Understand the network security policy management lifecycle, from creation to implementation and continuous review, ensuring optimal network protection and compliance. The network security policy management lifecycle Introduction IT security organizations today are judged on how they enable business transformation and innovation. They are tasked with delivering new applications to users and introducing new technologies that will capture new customers, improve productivity and lower costs. They are expected to be agile so they can respond faster than competitors to changing customer and market needs. Unfortunately, IT security is often perceived as standing in the way of innovation and business agility. This is particularly true when it comes to provisioning business application connectivity. When an enterprise rolls out a new application or migrates an application to the cloud it may take weeks or even months to ensure that all the servers, devices and network segments can communicate with each other, and at the same time prevent access to hackers and unauthorized users. But IT security does not have to be a bottleneck to business agility. Nor is it necessary to accept more risk to satisfy the demand for speed. The solution is to manage application connectivity and network security policies through a structured lifecycle methodology. IT security organizations that follow the five stages of a security policy management lifecycle can improve business agility dramatically without sacrificing security. A lifecycle approach not only ensures that the right activities are performed in the right order, it provides a framework for automating repeatable processes, and enables different technical and business groups to work together better. In this whitepaper, we will: Review the obstacles to delivering secure application connectivity and business agility. Explore the lifecycle approach to managing application connectivity and security policies. Examine how the activities at each stage of the lifecycle can help enterprises increase business agility, reduce risks, and lower operating costs. Schedule a Demo Why is it so hard to manage application and network connectivity? Top IT managers sometimes view security policy management as something routine, just part of the “plumbing.” In reality, delivering secure connectivity requires mastering complex data center and cloud infrastructures, coping with constant change, understanding esoteric security and compliance requirements, and coordinating the efforts of multiple technical and business teams. Application connectivity is complex The computing infrastructure of even a medium-sized enterprise includes hundreds of servers, storage systems, and network security devices such as firewalls, routers and load balancers. Complexity is magnified by the fact that many application components are now virtualized. Moreover, hybrid cloud architectures are becoming common. And since networking concepts differ profoundly between physical and cloud-based networks, unified visibility and control are very difficult to obtain. Change never stops Business users need access to data – fast! Yet every time a new application is deployed, changed or migrated, network and security staff need to understand how information will flow between the various web, application, database and storage servers. They need to devise application connectivity rules that allow traffic while preventing access from unauthorized users or creating gaps in their security perimeters. Security and compliance require thousands of application connectivity rules Many security policies are required to manage network access and protect confidential data from outside attackers and from unauthorized access by users or employees. In a typical enterprise, customers and businesses are only allowed to access specific web servers in a “demilitarized zone.” Some applications and databases are authorized for all employees, while others are restricted to specific departments or business units or management levels. Government regulations and industry standards require severely controlled access to credit card and financial information, Personally Identifiable Information (PII), Protected Health Information (PHI) and many other types of confidential data. Security best practices often require additional restrictions, such as limiting the use of protocols that can be used to evade security controls. To enforce these policies, IT security teams need to create and manage thousands, tens of thousands, and sometimes even hundreds of thousands of firewall rules on routers, firewalls and other network and security devices in order to comply with the necessary security, business and regulatory requirements. Technical and business groups don’t communicate After application delivery managers outline the business-level requirements of new or modified applications, network and security architects must translate them into network flows that traverse various web gateways, web servers, application servers, database servers and document repositories. Then firewall administrators and other security professionals have to create firewall rules that allow the right users to connect to the right systems, using appropriate services and protocols. Compliance and risk management officers also get involved to identify potential violations of regulations and corporate policies. These processes are handicapped by several factors: Each group speaks a different business or technical language. Information is siloed, and each group has its own tools for tracking business requirements, network topology, security rules and compliance policies. Data is often poorly documented. Often network and security groups are brought in only at the tail end of the process, when it is too late to prevent bad decisions.

Often network and security groups are brought in only at the tail end of the process, when it is too late to prevent bad decisions. Schedule a Demo The lifecycle approach to managing application connectivity and security policies Most enterprises take an ad-hoc approach to managing application connectivity. They jump to address the connectivity needs of high-profile applications and imminent threats, but have little time left over to maintain network maps, document security policies and firewall rules, or to analyze the impact of rule changes on production applications. They are also hard-pressed to translate dozens of daily change requests from business terms into complex technical details. The costs of these dysfunctional processes include: Loss of business agility, caused by delays in releasing applications and improving infrastructure. Application outages and lost productivity, caused by errors in updating rules and configuring systems. Inflexibility, when administrators refuse to change existing rules for fear of “breaking” existing information flows. Increased risk of security breaches, caused by gaps in security and compliance policies, and by overly permissive security rules on firewalls and other devices. Costly demands on the time of network and security staff, caused by inefficient processes and high audit preparation costs. IT security groups will always have to deal with complex networks and constantly changing applications. But given these challenges, they can manage application connectivity and security policies more effectively using a lifecycle framework such as the one illustrated in Figure 1. This lifecycle approach captures all the major activities that an IT organization should follow when managing change requests that affect application connectivity and security policies, organized into five stages. Figure 1: The Network Security Policy Lifecycle Structure activities and reduce risks A lifecycle approach ensures that the right activities are performed in the right order, consistently. This is essential to reducing risks. For example, failing to conduct an impact analysis of proposed firewall rule changes can lead to service outages when the new rules inadvertently block connections between components of an application. While neglecting to monitor policies and recertify rules can result in overly permissive or unnecessary rules that facilitate data breaches. A structured process also reduces unnecessary work and increases business agility. For example, a proactive risk and compliance assessment during the Plan & Assess stage of the lifecycle can identify requirements and prevent errors before new rules are deployed onto security and network devices. This reduces costly, time-consuming and frustrating “fire drills” to fix errors in the production environment. A defined lifecycle also gives network and security professionals a basis to resist pressures to omit or shortchange activities to save time today, which can cause higher costs and greater risks tomorrow. Automate processes The only way IT organizations can cope with the complexity and rapid change of today’s infrastructure and applications is through automation. A lifecycle approach to security policy management helps enterprises structure their processes to be comprehensive, repeatable and automated. When enterprises automate the process of provisioning security policies, they can respond faster to changing business requirements, which makes them more agile and competitive. By reducing manual errors and ensuring that key steps are never overlooked, they also avoid service outages and reduce the risk of security breaches and compliance violations. Automation also frees security and networking staffs so they have time to spend on strategic initiatives, rather than on routine “keep the lights on” tasks. Ultimately, it permits enterprises to support more business applications and greater business agility with the same staff. Enable better communication A lifecycle approach to security policy management improves communication across IT groups and their senior management. It helps bring together application delivery, network, security, and compliance people in the Discover & Visualize and Plan & Assess stages of the lifecycle, to make sure that business requirements can be accurately translated into infrastructure and security changes. The approach also helps coordinate the work of network, security and operations staffs in the Migrate & Deploy, Maintain and Decommission stages, to ensure that deployment and operational activities are executed smoothly. And it helps IT and business executives communicate better about the security posture of the enterprise. Document the environment In most enterprises security policies are poorly documented. Reasons include severe time pressures on network and security staff, and tools that make it hard to record and share policy and rule information (e.g., spreadsheets and bug tracking systems designed for software development teams). The result is minor time savings in the short run (“we’ll document that later when we have more time”) at the cost of more work later, lack of documentation needed for audits and compliance verification, and the greater risk of service outages and data breaches. Organizations that adopt a lifecycle approach build appropriate self-documenting processes into each step of the lifecycle. We will now look at how these principles and practices can be implemented in each of the five stages of a security policy management lifecycle. Schedule a Demo Stage 1: Discover & visualize The first stage of the security policy management lifecycle is Discover & Visualize. This phase is key to successful security policy management. It gives IT organizations an accurate, up-to-date mapping of their application connectivity across on-premises, cloud, and software-defined environments. Without this information, IT staff are essentially working blind, and will inevitably make mistakes and encounter problems down the line. While discovery may sound easy, for most IT organizations today it is extremely difficult to perform. As discussed earlier, most enterprises have hundreds or thousands of systems in their enterprise infrastructure. Servers and devices are constantly being added, removed, upgraded, consolidated, distributed, virtualized, and moved to the cloud. Few organizations can maintain an accurate, up-to-date map of their application connectivity and network topology, and it can take months to gather this information manually Fortunately, security policy management solutions can automate the application connectivity discovery, mapping, and documentation processes (see Figure 2). These products give network and security staffs an up-to-date map of their application connectivity and network topology, eliminating many of the errors caused by out-of-date (or missing) information about systems, connectivity flows, and firewall rules. In addition, the mapping process can help business and technical groups develop a shared understanding of application connectivity requirements. Figure 2: Auto discover, map and visualize application connectivity and security infrastructure Schedule a Demo Stage 2: Plan & assess Once an enterprise has a clear picture of its application connectivity and network infrastructure, it can effectively start to plan changes. The Plan & Assess stage of the lifecycle includes activities that ensure that proposed changes will be effective in providing the required connectivity, while minimizing the risks of introducing vulnerabilities, causing application outages, or violating compliance requirements. Typically, this stage involves: Translating business application connectivity requests, typically defined in business terms, into networking terminology that security staff can understand and implement. Analyzing the network topology, to determine if the requested changes are really needed (typically 30% of requests require no changes). Conducting a proactive impact analysis of proposed rule changes to understand in advance how they will affect other applications and processes. Performing a risk and compliance assessment, to make sure that the changes don’t open security holes or cause compliance violations (see Figure 3). Assessing inputs from vulnerabilities scanners and SIEM solutions to understand business risk. Many organizations perform these activities only periodically, in conjunction with audits or as part of a major project. They omit impact analysis for “minor” change requests and even when they perform risk assessments, they often focus on firewall rules and ignore the wider business application implications. Yet automating these analysis and assessment activities and incorporating them as part of a structured lifecycle process helps keep infrastructure and security data up to date, which saves time overall and prevents bad decisions from being made based on outdated information. It also ensures that key steps are not omitted, since even a single configuration error can cause a service outage or set the stage for a security breach. Impact analysis is particularly valuable when cloud-based applications and services are part of the project as it is often extremely difficult to predict the effect of rule changes when deployed to the cloud. Figure 3: Proactively assess risk and compliance for each security policy change Schedule a Demo Stage 3: Migrate & deploy The process of deploying connectivity and security rules can be extremely labor-intensive when it involves dozens of firewalls, routers, and other network security devices. It is also very error-prone. A single “fat-finger” typing mistake can result in an outage or a hole in the security perimeter. Security policy management solutions automate critical tasks during this stage of the lifecycle, including: Designing rule changes intelligently based on security, compliance and performance considerations. Automatically migrating these rules using intuitive workflows (see Figure 4). Pushing policies to firewalls and other security devices, both on-premise and on cloud platforms – with zero touch if no exceptions are detected (see Figure 5). Validating that the intended changes have been implemented correctly. Many enterprises overlook the validation process and fail to check that rule changes have been pushed to devices and activated successfully. This can create the false impression that application connectivity has been provided, or that vulnerabilities have been removed, when in fact there are time bombs ticking in the infrastructure. By automating these tasks, IT organizations can speed up application deployments, as well as ensure that rules are accurate and consistent across different security devices. Automated deployment also eliminates the need to perform many routine maintenance tasks and therefore frees up security professionals for more strategic tasks. Figure 4: Automate firewall rule migration through easy-to-use workflows Figure 5: Deploy security changes directly onto devices with zero touch Schedule a Demo Stage 4: Maintain In the rush to support new applications and technologies, many IT security teams ignore, forget or put off activities related to monitoring and maintaining their security policy – despite the fact that most firewalls accumulate thousands of rules and objects which become out-of-date or obsolete over the years. Typical symptoms of cluttered and bloated rulesets include: Overly permissive rules that create gaps in the network security perimeter which cybercriminals can use to attack the enterprise. Excessively complicated tasks in areas such as change management, troubleshooting and auditing. Excessive audit preparation costs to prove that compliance requirements are being met, or conversely audit failures because overly permissive rules allow violations. Slower network performance, because proliferating rules overload network and security devices. Decreased hardware lifespan and increased TCO for overburdened security devices. Cleaning up and optimizing security policies on an ongoing basis can prevent these problems (see Figure 6). Activities include: Identifying and eliminating or consolidating redundant and conflicting rules. Tightening rules that are overly permissive (for example, allowing network traffic from ANY source to connect to ANY destination using ANY protocol). Reordering rules for better performance. Recertifying expired rules based on security and business needs (see Figure 7). Continuously documenting security rules and their compliance with regulations and corporate policies. Figure 6: Automatically clean up and optimize security policies Automating these maintenance activities helps IT organizations move towards a “clean,” well-documented set of security rules so they can prevent business application outages, compliance violations, security holes, and cyberattacks. It also reduces management time and effort. Another key benefit of ongoing maintenance of security policy rules is that it significantly reduces audit preparation efforts and costs by as much as 80% (see Figure 8). Preparing firewalls for a regulatory or internal audit is a tedious, time-consuming and error-prone process. Moreover, while an audit is typically a point-in-time exercise, most regulations today require enterprises to be continually compliant, which can be difficult to achieve with bloated and ever-changing rule bases. Figure 7: Review and recertify rules based on security and business needs Figure 8: Significantly reduce audit preparation efforts and costs with automated audit reports Schedule a Demo Stage 5: Decommission Every business application eventually reaches the end of its life. At that point some or all of its security policies become redundant. Yet when applications are decommissioned, their policies are often left in place, either from oversight or out of fear that removing policies could negatively affect active business applications. These obsolete or redundant security policies increase the enterprise’s attack vector and add clutter, without providing any business value.A lifecycle approach to managing application connectivity and security policies reduces the risk of application outages and data breaches caused by obsolete rules. It provides a structured and automated process for identifying and safely removing redundant firewall rules as soon as applications are decommissioned, while verifying that their removal will not impact active applications or create compliance violations (see Figure 9). Figure 9: Automatically and safely remove redundant firewall rules when applications are decommissioned Schedule a Demo Summary Network and security operations should never be a bottleneck to business agility, and must be able to respond rapidly to the ever-changing needs of the business. The solution is to move away from a reactive, fire-fighting response to business challenges and adopt a proactive lifecycle approach to managing application connectivity and security policies that will enable IT organizations to achieve critical business objectives such as: Increasing business agility by speeding up the delivery of business continuity and business transformation initiatives. Reducing the risk of application outages due to errors when creating and deploying connectivity and security rules. Reducing the risk of security breaches caused by gaps in security and compliance policies and overly permissive security rules. Freeing up network and security professionals from routine tasks so they can work on strategic projects.

Get your application discovery and dependency mapping questions answered. Find clear explanations, best practices, and learn how to improve your understanding of your IT landscape. Application Discovery & Dependency Mapping Explained (FAQs) Introduction A network is the sum of its components, and if you want to ensure its functioning at the highest level, you need to be able to pinpoint every app that exists inside it. However, when the average company has 254 SaaS apps, identifying all the apps and dependencies that exist throughout an on-premise or cloud environment is easier said than done. Organizations cannot afford to rely on manual IP scanning to catalog or inventory each app their employees use every day; they need an AI-powered, automated, and scalable application discovery process. In this post we are going to examine what application discovery is, and how an automated dependency mapping tool can help. Schedule a Demo What is application discovery? Application discovery is the process of identifying and creating an inventory of the apps installed and used throughout an environment. This not only includes apps used within on-premise servers, but also those in the cloud, in containers, and even on employees’ personal devices. Discovering applications is essential for IT administrators because it helps to set out a framework they can use to navigate the network and understand how different elements fit together. It also enables security teams to manage the performance and security of the business apps used by the organization. Schedule a Demo What is a dependency mapping tool? A dependency mapping tool is essentially a tool that automatically maps apps and dependencies. A typical dependency mapping tool automates the discovery of applications within a network and provides a visual map to which an IT administrator can refer. Dependency mapping tools are a popular choice among IT teams because manually identifying and inventorying apps is a time-consuming process. Schedule a Demo Key benefits of application dependency mapping Taking the time to map application dependencies, or investing in a tool that automates the process, pays dividends because it provides administrators with a heightened understanding of their organization’s IT environment. Greater visibility over how apps connect to each other reduces the amount of time it takes to conduct troubleshooting and root cause analysis, which means that disruptions can be resolved faster, limiting the overall operational impact of downtime. Dependency mapping also enhances change management, giving administrators the ability to identify the impact that changing the topology or composition of the network will have on critical services. At the same time, better knowledge of the IT environment makes it easier to spot inefficiencies and redundancies, giving insights into more cost-effective ways of structuring the network and decreasing resource consumption. As an added bonus, having a complete understanding of application topology decreases the risk of vulnerabilities in the network, and reduces the likelihood of data leakage and intrusions from unauthorized third parties. Organizations interested in mapping application dependencies at scale would be well-advised to incorporate an application dependency mapping tool so they do not have to manually poll apps from scratch. Schedule a Demo Application discovery in cloud environments AlgoSec AlgoSec is the industry-leading AI-powered application and connectivity management solution for mapping apps, security policies, and connectivity flows across on-premise, hybrid, and multi-cloud environments. As a solution, it is designed to enable network security operations teams to map and understand app and connectivity flows through their organization. This top-down, topological perspective allows users to identify business risks and remediate them ASAP. For example, an administrator can use the platform to identify obsolete traffic that could serve as a potential entry point for malicious traffic. At a high level, application discovery not only helps administrators keep up with topology changes in the network and reduce the risk of downtime, it also provides the visibility needed to simplify the management of firewall and SSL configurations. Features Discovery of applications and connectivity flows Real-time map of app connectivity requirements Impact assessment of topology changes on application connectivity , security and compliance Complete easy-to-use workflows for streamlining migration to a new data center or cloud environment Zero-touch change management and access rule recertification Use cases Create a real-time map of applications and connectivity flows to outline network topology. Use workflows to support users who migrate apps as part of the data center migration process. Before migration, assess and predict the impact of topology changes on application connectivity, performance and security. Automatically configure application security policies post-migration. Amazon Web Services (AWS) and the AWS application discovery service AWS application discovery service is a common choice for migrating apps to an AWS environment. The AWS discovery service can automatically discover on-premise applications, and integrates with AWS Migration Hub to help migrate multiple applications at the same time. While this approach is useful for identifying applications in on-premise environments, unlike AlgoSec, it does not offer deep visibility into connectivity flows. It also offers limited support for cloud migration, lacking automated change management capabilities and migration workflows. Features The AWS application discovery service is designed to enable organizations to identify applications across AWS-powered cloud environments. The service includes the following features: Encrypt data in transit and at rest Create a snapshot of your on-premise application inventory Integrate discovery data with other AWS services, such as AWS Migration Hub and SMS Plan migrations for servers that share applications Connect applications to servers Group servers to migrate Mix agentless and agent-based approaches Use cases The main use case for AWS Application Discovery is discovering and creating an inventory of on-premise Information you can gather includes hostnames, IP addresses, MAC addresses and more. Map connections between applications and servers to create a visual representation of your network environment. Ingest utilization data to plan for your migration to the AWS Migration Hub. Microsoft Azure Migrate: Discovery and assessment tool One of the next biggest alternatives to the AWS application discovery service is the Microsoft Azure Migrate: Discovery and assessment tool. This solution enables users to automatically create an inventory of on-premise databases software, web apps, and SQL or AWS server instances. The Microsoft Azure Migrate: Discovery and assessment tool also integrates with Azure Monitor ’s Application Insight, an application monitoring solution. Oracle Cloud Infrastructure Oracle Cloud also offers its own migration tool designed to migrate on-premise applications and virtual machines from on-premise environments to Oracle Cloud Infrastructure using automated migration and provisioning. Oracle Cloud’s migration tool also offers templates, workflow automation and connectors for popular workloads including SQL Server, MySQL, Java, etc. Like Azure, Oracle Cloud also offers Application performance Monitoring integration. Schedule a Demo Other cloud providers and SaaS solutions Besides the top three cloud vendors, there are a number of other cloud security and SaaS-vendors offering application discovery capabilities. Some of these are listed below: Datadog Feature summary: Automated application and dependency mapping in real-time, alerts, latency graphs, and performance anomaly detection. Pros and cons: Rapid app and dependency mapping but beyond that lacks functionality for supporting cloud migrations. ManageEngine applications manager Feature summary: Application Discovery and Dependency Mapping (ADDM) with IP range application discovery, scheduled discoveries, scan summary reports, and a dependency map view. Pros and cons: IP range based discovery offers a broad view of apps and dependencies but does not offer migration workflows and change management capabilities. SolarWinds server & application monitor Feature summary: Polling to create application and dependency maps, tracking the response time of services, creating custom alerts for network latency, packet loss, and uptime monitoring. Pros and cons: Designed for monitoring application performance in on-premise environments, but it too lacks migration support. Schedule a Demo Application discovery in on-premises environments One of the main challenges that organizations face when trying to discover applications in on-premise environments is reliance on outdated legacy monitoring tools. Manually discovering and mapping applications is inefficient, and offers limited visibility over configuration data and metrics across the environment. Application discovery tools such as AlgoSec’s tools enable security teams to discover application dependencies and connections throughout the environment that could easily be overlooked by relying on manual approaches alone. Automation also opens the door for an organization to leverage virtualization technologies from providers like VMware and Hyper-V, which unlock new cloud-native capabilities that cannot necessarily be replicated on-premises. Schedule a Demo FAQs How does AlgoSec help with application discovery and asset management? AlgoSec can help you to discover, identify, and map applications across your on-premise and cloud environments in real-time using AI, so you can keep an up-to-date perspective of your entire network. How does AlgoSec help optimize traffic flows and improve firewall performance? Deploying AlgoSec enables an organization to scan traffic flows and match them to applications within the environment. Once you discovered traffic flows, you can start to automatically optimize application flows and the maximum number of flows per application in order to optimize your firewall throughput and performance for end users. How does AlgoSec help enforce security and compliance across the data center? Increased transparency of application, traffic and firewall flows makes it easier for IT security teams to assess the effectiveness of security policies in the environment, and creates an audit trail that can be used to manage potential compliance violations. Enhanced visibility makes it easier to maintain compliance and to ensure that security controls are effective at protecting your critical data assets from compromise or misuse. For example, administrators can automatically identify compliance gaps and generate compliance reports to document the state of firewalls and surrounding infrastructure to comply with PCI, HIPAA, SOX, and NERC. How does AlgoSec help with business continuity and disaster recovery? AlgoSec helps your organization to maintain business continuity not only through proactive network security policy management, but also by simplifying the process of migrating application connectivity flows and firewall policies to the cloud and ensuring compliance. Migrating your apps and data to a secondary site ensures that if your primary site is affected by a power outage or natural disaster, you will still be able to access critical information. Furthermore, according to an EMA survey, network security policy management also enhances business continuity by helping organizations to enforce more consistent security policies, conduct more proactive disaster recovery testing, and limit the number of change-related outages. How does AlgoSec help with data center migration? AlgoSec can help you to migrate your data center by discovering and mapping applications and connectivity flows, and connecting them to the relevant policies. Once these are discovered, the solution can migrate them to a new on-premise installation or cloud platform, while automatically identifying and removing obsolete and redundant firewall rules. This reduces the amount of overall manual processes associated with the migration. How does AlgoSec help with cloud cost optimization? AlgoSec’s application discovery and mapping capabilities help your organization to optimize costs in the cloud by giving you a reference point to conduct application performance monitoring and ensure that your cloud bandwidth is used efficiently. This ensures that you are getting the maximum throughput from your network infrastructure and are not being held back by outages or other application performance issues. What are ADDM solutions and their advantages? Application Discovery and Dependency Mapping (ADDM) is a category of software solutions that can map applications and dependencies to help human users understand how they connect together and interact. ADDM solutions are a popular choice for IT administrators because they enable users to identify and map dependencies automatically rather than spending a substantial amount of time locating them manually. How does application performance monitoring work? Application performance monitoring is where an organization monitors performance metrics from applications located throughout their environment. Monitoring application performance helps to generate insights into how to optimize system availability, performance and response time. It also helps to ensure that end users enjoy a solid user experience with minimal downtime. What are some common application discovery methods? There are a number of common application discovery methods that organizations can deploy. These include: Sweep and poll – A technique for discovering IT assets whereby a system pings IP addresses and identifies the devices that issue a response. Network monitoring – Monitoring real-time packet information to generate data on application dependencies. This can be done at the packet level by capturing packets or at the flow level with NetFlow. Agent on Server – A process for identifying applications that uses a software agent deployed to a server to conduct real-time monitoring of incoming and outgoing traffic in order to map dependencies. Orchestration-Level Discovery – Where an organization uses an orchestration platform like AlgoSec to discover applications and dependencies automatically without having to deploy agents to servers. What is the role of DevOps in application discovery? Application discovery plays an important role in the DevOps process because it enables development teams to work toward automated app deployment. Automating the discovery of apps and connectivity flows means that users do not need coding knowledge to understand the environment. Increased visibility also supports a DevSecOps strategy, offering security teams greater transparency over application components. For example, a security analyst can view apps and connected dependencies and get a clear perspective of the entire attack surface and potential vulnerabilities a hacker could exploit. What is the role of application discovery in cloud migration? Discovering applications and dependencies helps you to fast-track your cloud migration by identifying what components you need to move and allowing you to phase the deployment in steps. Schedule a Demo Take control of your network Gaining visibility over applications in your environment is a critical step on your journey toward enhancing your business agility and continuity and minimizing downtime. A better understanding of app topology helps administrators find risks and remediate them quickly to ensure ongoing compliance. If you cannot see how effectively your applications are being delivered, or how they perform, then there is no way to consistently optimize performance or enforce security policies. While manually developing an inventory of apps and dependencies is a time-consuming process, the AlgoSec platform can completely eliminate the need for this by discovering apps in real-time so you can see how these components connect to each other on-premise, and across the private or public cloud. Real-time visibility over apps gives you everything you need to manage performance, risk, and compliance challenges at enterprise pace.

Understand how to achieve and maintain firewall compliance with ISO/IEC 27001. Learn key requirements, best practices, and how to strengthen your overall security posture. Firewall ISO compliance: ISO/IEC 27001 explained Introductory prologue IT organizations and those dealing with digital assets often face many information security challenges. They must protect sensitive data from unauthorized access, as a crack in security can result in unimaginable losses. To keep information security risks minimal and optimize protection for organizations, ISO/IEC 27001 compliance was designed. What is ISO/IEC 27001 compliance? How does it work, and why does it matter? Read on to uncover answers to all your questions and more in this guide. Schedule a Demo What Is ISO/IEC 27001? ISO/IEC 27001 is an internationally accepted standard for data security. It is one of the standards jointly published by the ISO (International Standardization Organization) and IEC (International Electrotechnical Commission) in 2015. ISO/IEC 27001 aims to provide organizations with a framework for information security management, thereby protecting digital assets. Implementing the standard helps organizations minimize and effectively manage information security risks, such as hacks, data leaks or theft, and cyber attacks. Digital assets like intellectual property, software, employee information, and personal data are often a target for malicious actors. And that’s why asset management is crucial to companies and digital service providers. It demonstrates that the certified organization’s information security system is efficient as it follows the best practice. Any ISO/IEC 27001-certified organization can display its certification online (e.g., on its website, social media platforms, etc.) and offline. As a result, they get the trust and respect they deserve from partners, investors, customers, and other organizations. Schedule a Demo Evolution of ISO/IEC 27001 The International Standardization Organization (ISO) is a global federation of national standards bodies established in 1947. It is a leading organization that develops standards for ensuring the security of business systems. Since its emergence, ISO has published several standards, such as: ISO 27000 – Information Security Management Systems ISO 22301 – Business Continuity ISO 14000 – Environmental Management System ISO 45001 – Occupational Health and Safety ISO 9000 – Quality Management System etc. Although ISO/IEC 27001 was officially published in 2005, ISO had been providing measures for protecting digital systems and information before then. The rapid spread of the internet in the 1990s gave rise to the need for data security to prevent sensitive data from getting into the wrong hands. ISO 27001 was the first standard among the ISO 27000 series of standards for cybersecurity. Since its release, the standard has undergone revisions to tackle new and evolving cyber threats in the industry. The first revision took place in October 2013, when new controls were introduced, and the total controls numbered up to 114. This version is referred to as ISO/IEC 27001:2013 version. The second and latest revision of ISO/ICE 27001 was published in 2022 and enumerates 93 controls grouped into four sections. This revision was initially referred to as ISO/IEC 27001:2022 but is now known as ISO 27001. Another notable development in the latest version is the change in title. The new version’s complete title is – ISO 27001 (i.e., ISO/IEC 27001:2022) Information Security, Cybersecurity and Privacy Protection. Schedule a Demo Business Benefits of ISO/IEC 27001 Achieving ISO/IEC 27001 certification offers organizations several business benefits, especially for service providers handling people’s sensitive financial and personal data. Examples of such organizations are insurance companies, banks, health organizations, and financial institutions. Some of the business benefits of ISO 27001 are: 1. It prevents financial penalties and losses from data breaches Organizations that do not comply with the global security standard are at great risk of a data breach. Data breaches often attract financial penalties and cause companies to lose significant amounts. By implementing the best network security practices, organizations can prevent unnecessary financial losses and record more significant revenue in the long run. 2. It protects and enhances a company’s reputation. Partners, investors, and customers often prefer companies with a good reputation for handling data. In fact, the World Economic Forum states that reputation affects a quarter of a company’s market value. ISO/IEC 27001 certification can help businesses with an existing reputation to preserve their image. Companies with a previous record of security challenges can enhance their reputation and earn the trust and respect of others by becoming certified too. 3. Wins new business and sharpens competitive edge Certified companies stand a better chance of winning new businesses and recording more sales and profits than their competitors. That’s because clients want to feel safe knowing their data enjoy maximum protection. Also, certain organizations must attain other certifications like GDPR, HIPAA, NIST, etc., before commencing operation. And having ISO certification makes it easier to achieve such requirements. One major indicator that an organization can be trusted for security management is acquiring a worldwide certification. It sharpens its competitive advantage and propels the brand way ahead of others. 4. Improves structure and focus As businesses expand, new responsibilities arise, and it can be challenging to determine who should be responsible for what. But with ISO 27001 compliance, companies will have a clear structure to mirror. From authentication to network traffic management, the standard has an outlined structure that companies can apply to establish robust operations security. As a result, they can tackle rising needs while staying focused and productive. 5. It reduces the need for frequent audits. Organizations usually spend heavily performing frequent internal and external audits to generate valuable data about the state of their security. The data is deployed to improve cybersecurity so that threat intelligence and other security aspects are optimized. And even though it costs more and wastes more time, it doesn’t guarantee as much protection as implementing ISO 27001 standard. By becoming a certified name, companies can rest assured that the best cybersecurity practices protect them against attacks. Plus, frequent audits won’t be needed, thus saving cost and time. Schedule a Demo ISO/IEC 27001 Compliance Organizations looking to achieve ISO/IEC 27001 compliance must ensure the following: 1. Clearly Outline the Risk Assessment Process Develop your risk assessment process to detect vulnerabilities. State the categories of risks your organization is facing Outline your approach to tackle vulnerabilities. 2. Make Sure Executives Set the Tone Top management must be involved in the information security program. They should show financial support and be available to make strategic decisions that will help build robust security. Senior management should also conduct frequent assessments of the company’s ISMS to ensure it’s in sync with the globally agreed security standard. 3. Design an Information Security Policy (ISP) An ISP essentially functions to ensure that all the users and networks of your organization’s IT structure stick with the standard practices of digital data storage. You must design an effective ISP to achieve compliance as it governs information protection. Your ISP should encompass the A to Z of your organization’s IT security, including cloud security. You need to state who will be responsible for implementing the designed policy. 4. Write Out Your Statement of Applicability (SoA) Your SoA should carry core information about your ISMS. It should state the controls that your organization regards necessary to combat information security risks. It should document the controls that were not applied The SoA should only be shared with the certification body. 5. Create Your Risk Management Strategy Develop an effective risk management plan to address the possible risks of your chosen security controls. Ensure there’s an efficient security operations center (soc) to help detect cyber threats and forward notifications to the right systems. Design an information security incident management strategy to respond during threat detection. State who will implement specific security controls, how, and when they will deploy them. Schedule a Demo FAQs What does ISO/IEC 27001 stand for? ISO stands for International Standardization Organization, while IEC represents International Electrotechnical Commission. ISO/IEC 27001 is an internationally accepted standard for information security management, which ISO and IEC first created. What are the ISO 27001 Requirements? Every organization looking to apply for certification must prepare themselves and ensure to meet the requirements. These requirements are summarized in Clauses 4.1 to 10.2 below: 4.1 Understanding the organization and its context 4.2 Understanding the needs and expectations of interested parties 4.3 Determining the scope of the ISMS 4.4 Information security management system (ISMS) 5.1 Leadership and commitment 5.2 Information Security Policy 5.3 Organisational roles, responsibilities, and authorities 6.1 Actions to address risks and opportunities 6.2 Information security objectives and planning to achieve them 7.1 Resources 7.2 Competence 7.3 Awareness 7.4 Communication 7.5 Documented information 8.1 Operational planning and control 8.2 Information security risk assessment 8.3 Information security risk treatment 9.1 Monitoring, measurement, analysis, and evaluation 9.2 Internal audit 9.3 Management review 10.1 Nonconformity and corrective action 10.2 Continual improvement What are the ISO/IEC 27001 controls? The latest version of ISO 27001 Annex A enumerates 93 security controls divided into four sections or themes. The ISO 27001 controls are designed to simplify information security management such that digital assets get the best protection against security threats. These 4 sections are labelled A5 to A8 and are as follows: A.5 Organizational controls – containing 37 controls A.6 People controls – containing 8 controls A.7 Physical controls – containing 14 controls A.8 Technological controls – containing 34 controls How Does ISO/IEC 27001 ensure data protection? ISO/IEC 27001 ensures data protection by providing a framework through which companies can store sensitive data and have full access control. This standard can be adapted to suit each organization’s specific needs and structure, thereby offering optimized protection. ISO/IEC 27001 aims to ascertain that three core information security aspects are taken care of, which are: Confidentiality: this guarantees that only authorized individuals can access information. Also, because organizations deal with different categories of data, each employee must only be given the degree of access required to execute their tasks efficiently. Integrity: this ensures that only authorized individuals can change information on the system. So even in the event of a security breach, the risks are minimal. This is due to the change management plan that ensures unauthorized persons can not alter information. Availability: information security becomes a problem if the secured information isn’t accessible when needed. ISO 27001 enables authorized persons to have access to information whenever required to ensure that business operations are uninterrupted. By maintaining these guidelines, companies can put in place an effective information security system and risk management plan to prevent data leaks, theft, or hacks. How does my firewall management help with ISO 27001? Firewalls are the software in your organization’s IT structure managing the connection between different networks. Effective firewall management can help in designing the right Information Security Policy (ISP). In turn, your organization will be able to achieve ISO 27001 compliance. Thus, your firewall policies can help with ISO 27001 by enabling organizations to design an Information Security Policy that agrees with the standard required for compliance. What is the Importance of ISO 27001 Certification, and how can I gain it? ISO 27001 certification offers several advantages to businesses and organizations. It demonstrates to partners, investors, and customers that the certified business has a reliable information security management system, thus winning their trust. Also, it enhances communications security so that third parties do not interfere with your company’s operating system. You also get to reduce the risk of security failure, saving you from financial losses and penalties.

A network security policy is a critical part of your IT cyber policy It helps determine what traffic is allowed on your network, keeping critical assets secure Network security policy examples & procedures Introduction A network security policy delineates guidelines for computer network access, determines policy enforcement, and lays out the architecture of the organization’s network security environment and defines how the security policies are implemented throughout the network architecture. Network security policies describes an organization’s security controls. It aims to keep malicious users out while also mitigating risky users within your organization. The initial stage to generate a policy is to understand what information and services are available, and to whom, what the potential is for damage, and what protections are already in place. The security policy should define the policies that will be enforced – this is done by dictating a hierarchy of access permissions – granting users access to only what they need to do their work. These policies need to be implemented in your organization written security policies and also in your IT infrastructure – your firewall and network controls’ security policies. Schedule a Demo What is network security policy management? Network security policy management refers to how your security policy is designed and enforced. It refers to how firewalls and other devices are managed. Schedule a Demo Cyber Security Policies as Part of IT Security Policy A good IT security policy contains the following essentials: Purpose Audience Information security objective Authority and access control policy – This includes your physical security policy Data classification Data support and operations Security awareness and behavior Responsibility, rights, and duties A cyber security policy is part of your overall IT security. A cybersecurity policy defines acceptable cybersecurity procedures. Cybersecurity procedures explain the rules for how anyone with potential network access can access your corporate resources, whether they are in your physical offices, work remotely, or work in another company’s offices (for example, customers and suppliers), send data over networks. They also determine how organization’s manage security patches as part of their patch management policy. A good cybersecurity policy includes the systems that your business is using to protect your critical information and are already in place, including firewalls. It should align with your network segmentation and micro-segmentation initiatives. Schedule a Demo How AlgoSec helps you manage your network security policy?

Learn from expert-crafted firewall ruleset examples and best practices. Optimize your security posture with actionable guidance and improve your firewall configurations. Firewall ruleset examples & policy best practices Securing your network: guide to firewall rules examples Cyberattacks continue to rise globally as malicious actors tirelessly develop sophisticated tools and techniques to break through networks and security systems. With the digitalization of operations today and the increasing adoption of remote working, crucial business activities such as communication, data storage, and data transmission are now primarily done digitally. While this brings numerous advantages – allowing easy usability and scalability, enhancing collaboration, and reducing the risks of data loss – businesses have to deal with various security risks, such as data breaches and cyberattacks from hackers. Organizations must provide adequate network security to keep sensitive data safe and ensure their network is usable, trustworthy, and optimized for maximum productivity across all channels. Schedule a Demo Firewalls and your network Your network and systems (software and hardware) comprise the IT infrastructure through which you operate and manage your enterprise’s IT services. Every IT system regularly receives and transmits internet traffic, and businesses must ensure that only trusted and authorized traffic penetrates their network to maintain security. All unwanted traffic must be prevented from accessing your operating system as it poses a huge risk to network security. Malicious actors attempting to penetrate your system often send virus-carrying inbound traffic to your network. However, with an effective firewall, you can filter all traffic and block unwanted and harmful traffic from penetrating your network. A firewall serves as a barrier between computers, networks, and other systems in your IT landscape, preventing unauthorized traffic from penetrating. Schedule a Demo What are firewall rules? The firewall is your first line of defense in network security against hackers, malware, and other threats. Firewall rules refer to access control mechanisms that stipulate how a firewall device should handle incoming and outgoing traffic in your network. They are instructions given to firewalls to help them know when to block or allow communication in your network. These instructions include destination or source IP addresses, protocols, port numbers, and services. A firewall ruleset is formed from a set of rules and it defines a unit of execution and sharing for the rules. Firewall rulesets typically include: A source address A source port A destination address A destination port A decision on whether to block or permit network traffic meeting those address and port criteria Schedule a Demo What are the most common firewall ruleset examples? There are thousands of rulesets that can be used to control how a firewall deals with network traffic. Some firewall rules are more common than others, as they tend to be fundamental when building a secure network. Here are some examples of firewall rules for common use cases: Enable internet access for only one computer in the local network and block access for all others This rule gives only one computer in the local network access to the internet, and blocks all others from accessing the internet. This example requires obtaining the IP address of the computer being granted access (i.e., source IP address) and the TCP protocol type. Two rules will be created: a Permit rule and a Deny rule. The permit rule allows the chosen computer the required access, while the deny rule blocks all other computers in the local network from internet access. Prevent direct access from the public network to the firewall This rule blocks access to your firewall from any public network, to protect it from hackers who can modify or delete your rules if they access your firewall directly. Once hackers manipulate your rules, unwanted traffic will penetrate your network, leading to data breaches or an interruption in operation. A Deny rule for any attempt to access the firewall from public networks will be created and enabled. Block internet access for only one computer in the local network This rule comes in handy if you do not want a specific computer in the local network to access the internet. You will need to create a Deny rule in which you set the IP address of the computer you wish to block from the internet, and the TCP protocol type. Block access to a specific website from a local network In this scenario we want to configure our firewall to deny access to a particular website from a local network. We first obtain the IP address or addresses of the website we wish to deny access to, and then create a Deny rule. One way to obtain a website’s IP address is by running the special command ‘nslookup ’ in your operating system’s command line (Windows, Linux, or others). Since websites can run on HTTP and HTTPS, we must create a Deny rule for each protocol type and indicate the destination IP address(es). Thus, the local network will be unable to access both the HTTP and HTTPS versions of the website. Allow a particular LAN computer to access only one specific website This example gives a local computer access to only one specified website. We obtain the IP address of the destination website and the source IP address (of the local computer). We create a Permit rule for the source IP address and the destination website, and a Deny rule for the source IP address and other websites, taking the TCP protocol types into account. Allow internet access to and from the local network using specific protocols (services) only This example allows your LAN computer to access the internet using specific protocols, such as SMTP, FTP, IPv6, SSH, IPv4, POP3, DNS, and IMAP; and blocks all other traffic Here we first create an “Allow” rule for the “Home segment,” where we use the value “Any” for the Source and Destination IP addresses. In the Protocol field provided, we choose the protocols through which our local computer can access the internet. Lastly, we create Deny rules where we enter the value “Any” for the Source and Destination IP addresses. In the Protocol field, we set the values TCP and UDP, thus blocking internet access for unspecified protocols. Allow remote control of your router This rule enables you to access, view, or change your Router Settings remotely (over the internet). Typically, access to routers from the internet is blocked by default. To set this rule, you need specific data such as your router username, WAN IP address, and password. It is crucial to note that this setting is unsafe for individuals who use public IP addresses. A similar use case is a rule enabling users to check a device’s availability on their network by allowing ICMP ping requests. Block access from a defined internet subnet or an external network You can set a rule that blocks access to your network from a defined internet subnet or an external network. This rule is especially important if you observed repeated attempts to access your router from unknown IP addresses within the same subnet. In this case, set a Deny rule for IP addresses of the subnet attempting to access your WAN port. Schedule a Demo What are examples of best practices for setting up firewall rules? It is expedient to follow best practices during firewall configuration to protect your network from intruders and hackers. Deploying industry-standard rules when setting up firewalls can improve the security of your network and system components. Below are examples of the best practices for setting up firewall rules. Document firewall rules across multiple devices Documenting all firewall rule configurations and updating them frequently across various devices is one of the best practices for staying ahead of attacks. New rules should be included based on security needs, and irrelevant rules should be deactivated to reduce the possibility of a loophole in your network. With documentation, administrators can review the rules frequently and make any required changes whenever a vulnerability is detected. Configure your firewall to block traffic by default Using a block or deny-by-default policy is the safest way to deal with suspicious traffic. Enterprises must be sure that all types of traffic entering their network are identified and trusted to avoid security threats. In addition, whenever a vulnerability arises in the system, blocking by default helps prevent hackers from taking advantage of loopholes before administrators can respond. Monitor firewall logs Monitoring firewall logs on a regular basis helps maintain network security. Administrators can quickly and easily track traffic flow across your network, identify suspicious activity, and implement effective solutions in a timely manner. Organizations with highly sophisticated infrastructure can aggregate logs from routers, servers, switches, and other components to a centralized platform for monitoring. Group firewall rules to minimize complexity and enhance performance Depending on the complexity of your network, you may need thousands of rules to achieve effective network security. This complicates your firewall rules and can be a huge challenge for administrators. However, by grouping rules based on similar characteristics like protocols, TCP ports, IP addresses, etc., you simplify them and boost overall performance. Implement least-privileged access In any organization, employees have various roles and may require different data to execute their tasks efficiently. As part of network security practices, it’s important to ensure each employee’s access to the network is restricted to the minimum privileges needed to execute their tasks. Only users who require access to a particular service or resource should have it, thus preventing unnecessary exposure of data. This practice significantly minimizes the risk of intentional and accidental unauthorized access to sensitive data. Schedule a Demo How do firewall policies differ from a network security policy? A network security policy outlines the overall rules, principles, and procedures for maintaining security on a computer network. The policy sets out the basic architecture of an organization’s network security environment, including details of how the security policies are implemented. The overall objective of network security policy is to protect a computer network against internal and external threats. Firewall policies are a sub-group of network security policies, and refer to policies that relate specifically to firewalls. Firewall policies have to do with rules for how firewalls should handle inbound and outbound traffic to ensure that malicious actors do not penetrate the network. A firewall policy determines the types of traffic that should flow through your network based on your organization’s network and information security policies.
