Tags Share this article 8/9/23 Published A firewall that runs 24/7 requires a good amount of computing resources. Especially if you are running a complex firewall system, your performance overhead can actually slow down the overall throughput of your systems and even affect the actual functionalities of your firewall. Here is a brief overview of common firewall performance issues and the best practices to help you tune your firewall performance . 7 Common performance issues with firewalls Since firewall implementations often include some networking hardware usage, they can slow down network performance and traffic bottlenecks within your network. 1. High CPU usage The more network traffic you deal with, the more CPU time your server will need. When a firewall is running, it adds to CPU utilization since the processes need more power to execute the network packet analysis and subsequent firewall This may lead to firewall failures in extreme cases where the firewall process is completely shut down or the system experiences a noticeable lag affecting overall functionality. A simple way to resolve this issue would be to increase the hardware capabilities. But as that might not be a viable solution in all cases, you must consider minimizing the network traffic with router-level filtering or decreasing the server load with optimized 2. Route flapping Router misconfiguration or hardware failure can cause frequent advertising of alternate routes. This will increase the load on your resources and thus lead to performance issues. 3. Network errors and discards A high number of error packets or discarded packets can burden your resources as these packets are still processed by the firewall even when they ultimately turn out to be dud in terms of traffic. Such errors usually happen when routers try to reclaim some buffer space. 4. Congested network access link Network access link congestion can be caused due to a bottleneck happening between a high bandwidth IP Network and LAN. When there is high traffic, the router queue gets filled and causes jitters and time delays. When there are more occurrences of jitter, more packets are dropped on the receiving end, causing a degradation of the quality of audio or video being transmitted. This issue is often observed in VoIP systems . 5. Network link failure When packet loss continues for over a few seconds, it can be deemed a network link failure. While re-establishing the link could take just a few seconds, the routers may already be looking for alternate routes. Frequent network link failures can be a symptom of power supply or hardware issues. 6. Misconfigurations Software or hardware misconfigurations can easily lead to overloading of LAN, and such a burden can easily affect the system’s performance. Situations like these can be caused by misconfigured multicast traffic and can affect the overall data transfer rate of all users. 7. Loss of packets Loss of packets can cause timeout errors, retransmissions, and network slowness. Loss of packets can happen due to delayed operations, server slowdown, misconfiguration, and several other reasons. How to fine-Tune your firewall performance Firewall performance issues can be alleviated with hardware upgrades. But as you scale up, upgrading hardware at an increasing scale would mean high expenses and an overall inefficient system. A much better cost-effective way to resolve firewall performance issues would be to figure out the root cause and make the necessary updates and fixes to resolve the issues. Before troubleshooting, you should know the different types of firewall optimization techniques: Hardware updates Firewall optimization can be easily achieved through real-time hardware updates and upgrades. This is a straightforward method where you add more capacity to your computing resources to handle the processing load of running a firewall. General best practices This involves the commonly used universal best practices that ensure optimized firewall configurations and working. Security policies, data standard compliances , and keeping your systems up to date and patched will all come under this category of optimizations. Any optimization effort generally applied to all firewalls can be classified under this type. Vendor specific Optimization techniques designed specifically to fit the requirements of a particular vendor are called vendor-specific optimizations. This calls for a good understanding of your protected systems, how traffic flows, and how to minimize the network load. Model specific Similar to vendor-specific optimizations, model-specific optimization techniques consider the particular network model you use. For instance, the Cisco network models usually have debugging features that can slow down performance. Similarly, the PIX 6.3 model uses TCP intercept that can slow down performance. Based on your usage and requirements, you can turn the specific features on or off to boost your firewall performance. Best practices to resolve the usual firewall performance bottlenecks Here are some proven best practices to improve your firewall’s performance. Additionally, you might also want to read Max Power by Timothy Hall for a wholesome understanding. Standardize your network traffic Any good practice starts with rectifying your internal errors and vulnerabilities. Ensure all your outgoing traffic aligns with your cybersecurity standards and regulations. Weed out any application or server sending out requests that don’t comply with the security regulations and make the necessary updates to streamline your network. Router level filtering To reduce the load on your firewall applications and hardware, you can use router-level network traffic filtering. This can be achieved by making a Standard Access List filter from the previously dropped requests and then routing them using this list for any other subsequent request attempts. This process can be time-consuming but is simple and effective in avoiding bottlenecks. Avoid using complicated firewall rules Complex firewall rules can be resource heavy and place a lot of burden on your firewall performance. Simplifying this ruleset can boost your performance to a great extent. You should also regularly audit these rules and remove unused rules. To help you clean up firewall rules, you can start with Algosec’s firewall rule cleanup and performance optimization tool . Test your firewall Regular testing and auditing of your firewall can help you identify any probable causes for performance slowdown. You can collect information on your network traffic and use it to optimize how your firewall operates. You can use Algosec’s firewall auditor services to take care of all your auditing requirements and ensure compliance at all levels. Make use of common network troubleshooting tools To analyze the network traffic and troubleshoot your performance issues, you can use common network tools like netstat and iproute2. These tools provide you with network stats and in-depth information about your traffic that can be well utilized to improve your firewall configurations. You can also use check point servers and tools like SecureXL, and CoreXL. Follow a well-defined security policy As with any security implementation, you should always have a well-defined security policy before configuring your firewalls. This gives you a good idea of how your firewall configurations are made and lets you simplify them easily. Change management is also essential to your firewall policy management process . You should also document all the changes, reviews, and updates you make to your security policies to trace any problematic configurations and keep your systems updated against evolving cyber threats. A good way to mitigate security policy risks is to utilize AlgoSec. Network segmentation Segmentation can help boost performance as it helps isolate network issues and optimize bandwidth allocation. It can also help to reduce the traffic and thus further improve the performance. Here is a guide on network segmentation you can check out. Automation Make use of automation to update your firewall settings. Automating the firewall setup process can greatly reduce setup errors and help you make the process more efficient and less time-consuming. You can also extend the automation to configure routers and switches. Algobot is an intelligent chatbot that can effortlessly handle network security policy management tasks for you. Handle broadcast traffic efficiently You can create optimized rules to handle broadcast traffic without logging to improve performance. Make use of optimized algorithms Some firewalls, such as the Cisco Pix, ASA 7.0 , Juniper network models, and FWSM 4.0 are designed to match packets without dependency on rule order. You can use these firewalls; if not, you will have to consider the rule order to boost the performance. To improve performance, you should place the most commonly used policy rules on the top of the rule base. The SANS Institute recommends the following order of rules: Anti-spoofing filters User permit rules Management permit rules Noise drops Deny and alert Deny and log DNS objects Try to avoid using DNS objects that need DNS lookup services. This slows down the firewall. Router interface design Matching the router interface with your firewall interface is a good way to ensure good performance. If your router interface is half duplex and the firewall is full duplex, the mismatch can cause some performance issues. Similarly, you should try to match the switch interface with your firewall interface, making them report on the same speed and mode. For gigabit switches, you should set up your firewall to automatically adjust speed and duplex mode. You can replace the cables and patch panel ports if you cannot match the interfaces. VPN If you are using VPN and firewalls, you can separate them to remove some VPN traffic and processing load from the firewall and thus increase the performance. UTM features You can remove the additional UTM features like Antivirus, and URL scanning features from the firewall to make it more efficient. This does not mean you completely eliminate any additional security features. Instead, just offload them from the firewall to make the firewall work faster and take up fewer computing resources. Keep your systems patched and updated Always keep your systems, firmware, software, and third-party applications updated and patched to deal with all known vulnerabilities.

Understand HIPAA network compliance requirements. Learn how to safeguard patient data with robust network security measures and ensure compliance with HIPAA regulations. HIPAA network compliance & security requirements explained The advancement in data management technology has revolutionized how healthcare providers offer their services. Digital or electronic solutions are integrated into healthcare processes to improve productivity, enhance efficiency, and meet patients’ demands. Before digital transformation swept across the healthcare industry, healthcare providers at all levels relied upon manual methods and traditional data processing to carry out their day-to-day activities. Today, modern solutions, like computerized physician order entry (CPOE) and electronic health records (EHR), have replaced them, streamlining repetitive tasks, encouraging collaboration, and improving data sharing. Even though using computerized systems and other medical record management systems is very helpful, the security of confidential healthcare information has been a major challenge. To ensure that the privacy and security of patients’ information are maintained, the government created a law to enforce compliance (by organizations) with security best practices. This is where HIPAA comes in! What are HIPAA network compliance requirements, rules, and violations? This refers to compliance with regulatory standards that outline what organizations that handle protected health information (PHI) must do to ensure the privacy and security of patients’ data. The U.S. Health Insurance Portability and Accountability Act (HIPAA) requires healthcare providers and their business associates to implement physical, network, and process security measures to ensure the security of PHI. HIPAA regulations set clear standards that health organizations must meet when managing patients’ sensitive data, like patient medical records, health insurance information, and other personally identifiable information. What is HIPAA compliance? According to the HIPAA, the Privacy Rule covers: Health plans Health care clearinghouses Healthcare providers who execute certain financial and administrative transactions electronically. Who needs to be HIPAA-compliant? There are some measures organizations are required to implement to protect patients’ sensitive data. If your company is a “covered entity”, it is expected to meet the following compliance requirements: 1. Have a dedicated HIPAA privacy officer There is a need for a professional who understands HIPAA and how to comply with the regulations. The officer will guide your organization on the right path and implement necessary measures to avoid HIPAA violations. And when a data breach or violation happens, the officer should restore order following the provisions of the act. 2. Identify and classify sensitive data Does your organization manage data that is not subject to HIPAA regulations? If that is the case, identify and classify sensitive information that should be handled according to HIPAA requirements. This helps you to implement security measures with little or no ambiguity. 3. Staff training Malicious actors usually target employees of organizations they want to attack. To equip your staff with the ability to spot attacks from a distance, you need to institute staff training. Your employees need to learn how to implement physical, administrative, and technical safeguards to protect PHI. 4. Institute strict data management policies Getting your staff trained on HIPAA laws and regulations is not enough. They need good leadership to uphold data security standards. Establish data management policies to enforce best practices and regulate access privileges. 5. Equip your facilities with security solutions Access control is a significant part of HIPAA compliance. Ensure unauthorized users don’t have access to computers, documents, or sensitive parts of workstations. You can achieve this by implementing security measures that regulate access to data and notify you when someone trespasses. 6. Install encryption software where necessary Data encryption solutions make files inaccessible to cybercriminals. Cloud solutions and other digital methods of storing data have increased the surface area for attacks. Malicious cyber actors are relentlessly scouring the internet for security vulnerabilities. Safeguarding patients’ data with encryption software is the way to go. 7. Enforce common best practices Visiting a malware-compromised website or clicking an ‘infected’ link can make your organization prone to a security breach. Encourage safe browsing and adopt security solutions, like email security software and antivirus systems. 8. File disposal policy Don’t dispose of documents or storage devices without rendering them unreadable. The best way to dispose of documents and records is to destroy them – by shredding or burning them. 9. Establish procedures for handling data breaches The primary goal is to prevent a security breach. However, the undesirable happens, and you need to be ready for the worst-case scenario. Establish and maintain procedures for managing security challenges. Ensure you appoint well-trained security experts who can respond swiftly when a breach occurs. 10. Monitor & review your assets & procedures regularly Keep an eye on your data assets and management policies. This helps you to identify inefficiencies and adopt measures to plug loopholes. Regular review is necessary to ensure you are keeping up with best practices. Remove outdated solutions and procedures to stay a thousand steps ahead of criminals. 11. Implement a strict backup policy Implement a backup strategy that conforms with the dictates of HIPAA. That said, having a good backup policy helps you clean up a data breach quickly. The general backup best practice is to have three copies of data at three different premises – on-site, off-site, and cloud locations. 12. Establish and maintain a disaster recovery plan A disaster recovery plan outlines how your organization will restore operations and manage stakeholders after a security breach. It details how your security team will respond to emergencies or the aftermath of security problems. Remember, your disaster recovery system should comply with the provisions of HIPAA. What are HIPAA compliance requirements? The major HIPAA rules are the Privacy Rule , Security Rule , Breach Notification Rule , and Omnibus Rule . Let’s take a look at each rule. The HIPAA privacy rule The HIPAA Privacy Rule is a regulatory framework that mandates covered entities and their business associates to uphold patients’ rights to data privacy. The privacy rule states what constitutes electronically protected health information, how it should be safeguarded, and the DOs and DON’Ts of PHI management. In a nutshell, this rule establishes how patients’ sensitive information should be protected, stored, used, shared, and disclosed. Any identifiable patient data is subject to the Privacy Rule. The PHI includes: Any past, present or future documentation on physical or mental conditions Healthcare records of the patient Records showing past, present, or future healthcare payment information According to the Privacy Rule , covered entities and their business associates are responsible for protecting PHI. There are cases where organizations can disclose private health information. But such scenarios are strictly defined by the rule and subject to legal interpretation. The HIPAA security rule While the Privacy Rule defines what privacy and ePHI (electronic PHI) are, the Security Rule is a framework that outlines the standards required to ensure the security of electronically protected health information. The security rule covers every aspect of your organization’s operations, from administration and physical processes to computers and technology equipment. The security rule has five sections: general rules, administrative safeguards, physical safeguards, technical safeguards, and organizational requirements. The General Rules The General rules mandate organizations to: Protect ePHI from reasonably anticipated threats or hazards Prevent any reasonably anticipated uses or disclosures of PHI that are not in line with the provisions of the Privacy Rule Enforce compliance with the security rule by the employees The Administrative Safeguards The Administrative Safeguards require the implementation of security policies and procedures. It dictates that the Security Officer should be responsible for conducting risk analyses, staff training, adopting risks and vulnerability management measures, and other administrative measures. The Physical Safeguards The physical safeguards outline how physical access to ePHI should be regulated. Whether the ePHI is stored in the cloud, in a remote data center, or on on-premise servers, there should be a strict policy that regulates access. This section of the security rule also states how access to workstations and devices should be safeguarded. The Technical Safeguards This part of the security rules focuses on ensuring that every person accessing ePHI is legitimate and does exactly what they are supposed to do. The technical safeguards help to ensure that security challenges are identified and rectified timely. The safeguards cover access controls, audit controls, integrity controls, transmission security, and any person or entity authentication. Organizational Requirements This section states the things business associate agreements must cover. Organizational Requirements stipulate that: Business associate agreements must provide that the business associates comply with the relevant parts of the security rule. Business associates must ensure compliance with subcontractors by entering into an Agreement with them. Business associates will report any security breach to the concerned covered entity. The HIPAA breach notification rule As much as organizations strive to comply with the requirements of HIPAA, security breaches still happen. It’s difficult, if not impossible, for covered entities and business associates to protect data with 100% effectiveness. Organizations must notify the public and the data subjects about a breach and disclose the steps they are taking to contain the problem. The Breach Notification Rule outlines what covered entities need to do when a breach occurs. Organizations are required to: Notify the people affected by the breach Inform the affected people within 60 days of the discovery of the security incident Provide a public notice if more than 500 individuals are impacted And more! The HIPAA omnibus rule According to the Omnibus Rule, organizations outside of covered entities (business associates and contractors) must meet compliance obligations. This rule states that covered entities are responsible for ensuring that business associates and contractors are compliant. Consequently, covered entities have to implement compliance measures to avoid any violations. What are the four main HIPAA rules? Violation is said to have occurred when an organization fails to comply with or meet the requirements of HIPAA. There are two major categories of violations: civil and criminal violations. Civil violations are committed accidentally or without malicious intent. On the other hand, criminal violations are done with malicious intent. As expected, penalties for civil violations are less than that for criminal violations. Here are some examples of violations and tips on how to avoid them: Illegal exposure of patients’ data Disclosing patients’ data to unauthorized parties accidentally or on purpose violates HIPAA provisions. There is a guideline for disclosing sensitive healthcare information. When due process is not followed, a violation occurs. And the penalty for unlawful disclosure of medical records depends on a range of factors, including whether it’s a civil or criminal violation. To avoid this type of violation, implement strict administrative policies. Allow only a few well-trained administrators to have the privilege to access or disclose data. When data access is strictly regulated, you can easily prevent unauthorized access and keep tabs on data management. Failure to implement proper security best practices The HIPAA security rule outlines the security protocols covered entities are required to implement. Given the complexity of data protection today, it’s easy to leave important things undone. You can avoid this by appointing an experienced security officer. You should also set up a committee of security professionals responsible for ensuring the proper implementation of security protocols. Lack of a consistent training policy It takes consistent staff training to meet the requirements of HIPAA. Both old and new employees need to be trained from time to time on how to protect healthcare data. Make training an integral part of your administrative policy. Non-compliance to security regulations is mainly caused by people. No matter the type of access management or security risk mitigation software you implement, you need an informed workforce to ensure compliance. Lack of proper notification after a security breach The HIPAA breach notification rule states how healthcare service providers should notify affected data subjects and public officials after a security incident. Failure to do so accordingly results in HIPAA violation. To avoid this, appoint a HIPAA compliance officer to monitor compliance gaps and ensure that requirements are met at every point in time. In addition, your contingency plan or disaster recovery system should contain a guideline on how to notify impacted parties when things go wrong. Lack of measures to address existing compliance gaps Neglecting existing compliance gaps or not doing the needful to avoid potential security problems violates HIPAA. Healthcare organizations are expected to act proactively, leveraging risk assessment and risk management policy to protect PHI. To close compliance gaps, do the following: Establish a HIPAA compliance enforcement team and a compliance officer Keep all software updated Conduct HIPAA audits regularly Work with a health information technology and security company that offers HIPAA compliance services. What are HIPAA violations and how to avoid them? HIPAA compliance requirements can be challenging to meet. The requirements are many, and you need teams of dedicated experts to interpret and design compliance strategies. Managing in-house teams of compliance experts is capital-intensive and time-consuming. Therefore outsourcing compliance duties to a technology and security vendor is the way to go.

Firewall Change Management 5 Types of Firewalls for Enhanced Network Security Asher Benbenisty 9 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/25/23 Published Firewalls form the first line of defense against intrusive hackers trying to infiltrate internal networks and steal sensitive data. They act as a barrier between networks, clearly defining the perimeters of each. The earliest generation of packet-filter firewalls were rudimentary compared to today’s next-generation firewalls, but cybercrime threats were also less sophisticated. Since then, cybersecurity vendors have added new security features to firewalls in response to emerging cyber threats. Today, organizations can choose between many different types of firewalls designed for a wide variety of purposes. Optimizing your organization’s firewall implementation requires understanding the differences between firewalls and the network layers they protect. How Do Firewalls Work? Firewalls protect networks by inspecting data packets as they travel from one place to another. These packets are organized according to the transmission control protocol/internet protocol (TCP/IP), which provides a standard way to organize data in transit. This protocol is a concise version of the more general OSI model commonly used to describe computer networks. These frameworks allow firewalls to interpret incoming traffic according to strictly defined standards. Security experts use these standards to create rules that tell firewalls what to do when they detect unusual traffic. The OSI model has seven layers: Application Presentation Session Transport Network Data link Physical Most of the traffic that reaches your firewall will use one of the three major Transport layer protocols in this model, TCP, UDP, or ICMP. Many security experts focus on TCP rules because this protocol uses a three-step TCP handshake to provide a reliable two-way connection. The earliest firewalls only operated on the Network Layer, which provides information about source and destination IP addresses, protocols, and port numbers. Later firewalls added Transport Layer and Application Layer functionality. The latest next-generation firewalls go even further, allowing organizations to enforce identity-based policies directly from the firewall. Related Read : Host-Based vs. Network-Based Firewalls 1. Traditional Firewalls Packet Filtering Firewalls Packet-filtering firewalls only examine Network Layer data, filtering out traffic according to the network address, the protocol used, or source and destination port data. Because they do not inspect the connection state of individual data packets, they are also called stateless firewalls. These firewalls are simple and they don’t support advanced inspection features. However, they offer low latency and high throughput, making them ideal for certain low-cost inline security applications. Stateful Inspection Firewalls When stateful firewalls inspect data packets, they capture details about active sessions and connection states. Recording this data provides visibility into the Transport layer and allows the firewall to make more complex decisions. For example, a stateful firewall can mitigate a denial-of-service attack by comparing a spike in incoming traffic against rules for making new connections – stateless firewalls don’t have a historical record of connections to look up. These firewalls are also called dynamic packet-filtering firewalls. They are generally more secure than stateless firewalls but may introduce latency because it takes time to inspect every data packet traveling through the network. Circuit-Level Gateways Circuit-level gateways act as a proxy between two devices attempting to connect with one another. These firewalls work on the Session layer of the OSI model, performing the TCP handshake on behalf of a protected internal server. This effectively hides valuable information about the internal host, preventing attackers from conducting reconnaissance into potential targets. Instead of inspecting individual data packets, these firewalls translate internal IP addresses to registered Network Address Translation (NAT) addresses. NAT rules allow organizations to protect servers and endpoints by preventing their internal IP address from being public knowledge. 2. Next-Generation Firewalls (NGFWs) Traditional firewalls only address threats from a few layers in the OSI model. Advanced threats can bypass these Network and Transport Layer protections to attack web applications directly. To address these threats, firewalls must be able to analyze individual users, devices, and data assets as they travel through complex enterprise networks. Next-generation firewalls achieve this by looking beyond the port and protocol data of individual packets and sessions. This grants visibility into sophisticated threats that simpler firewalls would overlook. For example, a traditional firewall may block traffic from an IP address known for conducting denial-of-service attacks. Hackers can bypass this by continuously changing IP addresses to confuse and overload the firewall, which may allow routing malicious traffic to vulnerable assets. A next-generation firewall may notice that all this incoming traffic carries the same malicious content. It may act as a TCP proxy and limit the number of new connections made per second. When illegitimate connections fail the TCP handshake, it can simply drop them without causing the organization’s internal systems to overload. This is just one example of what next-gen firewalls are capable of. Most modern firewall products combine a wide variety of technologies to provide comprehensive perimeter security against comprehensive cyber attacks. How do NGFWs Enhance Network Security? Deep Packet Inspection (DPI) : NGFWs go beyond basic packet filtering by inspecting the content of data packets. They analyze the actual data payload and not just header information. This allows them to identify and block threats within the packet content, such as malware, viruses, and suspicious patterns. Application-Level Control : NGFWs can identify and control applications and services running on the network. This enables administrators to define and enforce policies based on specific applications, rather than just port numbers. For example, you can allow or deny access to social media sites or file-sharing applications. Intrusion Prevention Systems (IPS) : NGFWs often incorporate intrusion prevention capabilities. They can detect and prevent known and emerging cyber threats by comparing network traffic patterns against a database of known attack signatures. This proactive approach helps protect against various cyberattacks. Advanced Threat Detection: NGFWs use behavioral analysis and heuristics to detect and block unknown or zero-day threats. By monitoring network traffic for anomalies, they can identify suspicious behavior and take action to mitigate potential threats. U ser and Device Identification : NGFWs can associate network traffic with specific users or devices, even in complex network environments. This user/device awareness allows for more granular security policies and helps in tracking and responding to security incidents effectively. Integration with Security Ecosystem : NGFWs often integrate with other security solutions, such as antivirus software, intrusion detection systems (IDS), and security information and event management (SIEM) systems. This collaborative approach provides a multi-layered defense strategy . Security Automation : NGFWs can automate threat response and mitigation. For example, they can isolate compromised devices from the network or initiate other predefined actions to contain threats swiftly. In a multi-layered security environment, these firewalls often enforce the policies established by security orchestration, automation, and response (SOAR) platforms. Content Filtering : NGFWs can filter web content, providing URL filtering and content categorization. This helps organizations enforce internet usage policies and block access to potentially harmful or inappropriate websites. Some NGFWs can even detect outgoing user credentials (like an employee’s Microsoft account password) and prevent that content from leaving the network. VPN and Secure Remote Access : NGFWs often include VPN capabilities to secure remote connections. This is crucial for ensuring the security of remote workers and branch offices. Advanced firewalls may also be able to identify malicious patterns in external VPN traffic, protecting organizations from threat actors hiding behind encrypted VPN providers. Cloud-Based Threat Intelligence : Many NGFWs leverage cloud-based threat intelligence services to stay updated with the latest threat information. This real-time threat intelligence helps NGFWs identify and block emerging threats more effectively. Scalability and Performance : NGFWs are designed to handle the increasing volume of network traffic in modern networks. They offer improved performance and scalability, ensuring that security does not compromise network speed. Logging and Reporting : NGFWs generate detailed logs and reports of network activity. These logs are valuable for auditing, compliance, and forensic analysis, helping organizations understand and respond to security incidents. 3. Proxy Firewalls Proxy firewalls are also called application-level gateways or gateway firewalls. They define which applications a network can support, increasing security but demanding continuous attention to maintain network functionality and efficiency. Proxy firewalls provide a single point of access allowing organizations to assess the threat posed by the applications they use. It conducts deep packet inspection and uses proxy-based architecture to mitigate the risk of Application Layer attacks. Many organizations use proxy servers to segment the parts of their network most likely to come under attack. Proxy firewalls can monitor the core internet protocols these servers use against every application they support. The proxy firewall centralizes application activity into a single server and provides visibility into each data packet processed. This allows the organization to maintain a high level of security on servers that make tempting cyberattack targets. However, these servers won’t be able to support new applications without additional firewall configuration. These types of firewalls work well in highly segmented networks that allow organizations to restrict access to sensitive data without impacting usability and production. 4. Hardware Firewalls Hardware firewalls are physical devices that secure the flow of traffic between devices in a network. Before cloud computing became prevalent, most firewalls were physical hardware devices. Now, organizations can choose to secure on-premises network infrastructure using hardware firewalls that manage the connections between routers, switches, and individual devices. While the initial cost of acquiring and configuring a hardware firewall can be high, the ongoing overhead costs are smaller than what software firewall vendors charge (often an annual license fee). This pricing structure makes it difficult for growing organizations to rely entirely on hardware devices. There is always a chance that you end up paying for equipment you don’t end up using at full capacity. Hardware firewalls offer a few advantages over software firewalls: They avoid using network resources that could otherwise go to value-generating tasks. They may end up costing less over time than a continuously renewed software firewall subscription fee. Centralized logging and monitoring can make hardware firewalls easier to manage than complex software-based deployments. 5. Software Firewalls Many firewall vendors provide virtualized versions of their products as software. They typically charge an annual licensing fee for their firewall-as-a-service product, which runs on any suitably provisioned server or device. Some software firewall configurations require the software to be installed on every computer in the network, which can increase the complexity of deployment and maintenance over time. If firewall administrators forget to update a single device, it may become a security vulnerability. At the same time, these firewalls don’t have their own operating systems or dedicated system resources available. They must draw computing power and memory from the devices they are installed on. This leaves less power available for mission-critical tasks. However, software firewalls carry a few advantages compared to hardware firewalls: The initial subscription-based cost is much lower, and many vendors offer a price structure that ensures you don’t pay for resources you don’t use. Software firewalls do not take up any physical space, making them ideal for smaller organizations. The process of deploying software firewalls often only takes a few clicks. With hardware firewalls, the process can involve complex wiring and time-consuming testing. Advanced Threats and Firewall Solutions Most firewalls are well-equipped to block simple threats, but advanced threats can still cause problems. There are many different types of advanced threats designed to bypass standard firewall policies. Advanced Persistent Threats (APTs) often compromise high-level user accounts and slowly spread throughout the network using lateral movement. They may move slowly, gathering information and account credentials over weeks or months before exfiltrating the data undetected. By moving slowly, these threats avoid triggering firewall rules. Credential-based attacks bypass simple firewall rules by using genuine user credentials to carry out attacks. Since most firewall policies trust authenticated users, attackers can easily bypass rules by stealing user account credentials. Simple firewalls can’t distinguish between normal traffic and malicious traffic by an authenticated, signed-in user. Malicious insiders can be incredibly difficult to detect. These are genuine, authenticated users who have decided to act against the organization’s interest. They may already know how the firewall system works, or have privileged access to firewall configurations and policies. Combination attacks may target multiple security layers with separate, independent attacks. For example, your cloud-based firewalls may face a Distributed Denial of Service (DDoS) attack while a malicious insider exfiltrates information from the cloud. These tactics allow hackers to coordinate attacks and cover their tracks. Only next-generation firewalls have security features that can address these types of attack. Anti-data exfiltration tools may prevent users from sending their login credentials to unsecured destinations, or prevent large-scale data exfiltration altogether. Identity-based policies may block authenticated users from accessing assets they do not routinely use. Firewall Configuration and Security Policies The success of any firewall implementation is determined by the quality of its security rules. These rules decide which types of traffic the firewall will allow to pass, and what traffic it will block. In a modern network environment, this is done using four basic types of firewall rules: Access Control Lists (ACLs). These identify the users who have permission to access a certain resource or asset. They may also dictate which operations are allowed on that resource or asset. Network Address Translation (NAT) rules. These rules protect internal devices by hiding their original IP address from the public Internet. This makes it harder for hackers to gain unauthorized access to system resources because they can’t easily target individual devices from outside the network. Stateful packet filtering . This is the process of inspecting data packets in each connection and determining what to do with data flows that do not appear genuine. Stateful firewalls keep track of existing connections, allowing them to verify the authentication of incoming data that claims to be part of an already established connection. Application-level gateways. These firewall rules provide application-level protection, preventing hackers from disguising malicious traffic as data from (or for) an application. To perform this kind of inspection, the firewall must know what normal traffic looks like for each application on the network, and be able to match incoming traffic with those applications. Network Performance and Firewalls Firewalls can impact network performance and introduce latency into networks. Optimizing network performance with firewalls is a major challenge in any firewall implementation project. Firewall experts use a few different approaches to reduce latency and maintain fast, reliable network performance: Installing hardware firewalls on high-volume routes helps, since separate physical devices won’t draw computing resources away from other network devices. Using software firewalls in low-volume situations where flexibility is important. Sometimes, being able to quickly configure firewall rules to adapt to changing business conditions can make a major difference in overall network performance. Configuring servers to efficiently block unwanted traffic is a continuous process. Server administrators should avoid overloading firewalls with denied outbound requests that strain firewalls at the network perimeter. Firewall administrators should try to distribute unwanted traffic across multiple firewalls and routers instead of allowing it to concentrate on one or two devices. They should also try reducing the complexity of the firewall rule base and minimize overlapping rules.

Tags Share this article 11/27/20 Published With the rapid proliferation of cloud computing, lean deployment methods, such as containers, have become common practice. According to CIO.com, 70% of global companies are expected to be running multiple apps simultaneously using a containerized framework, like Kubernetes in the next few years. But as Kubernetes’ use becomes more widespread, so do the vulnerabilities inherent to containerization. According to a 2019 Forbes article , Kubernetes had at least 7,000 identified vulnerabilities at the beginning of 2019 alone. Couple that with the fact that cyber-attacks involving containerization have increased a whopping 240% since 2018, and you’ll understand the value of security should your company use a solution like Kubernetes to handle its container orchestration. What Causes Kubernetes Security Blindspots? To understand how to best optimize your Kubernetes experience, it’s worthwhile to understand the basic ways security issues arise in a containerized framework. Images are the core building blocks of containerization; they are the executable process at the centre of your container. As a result, anything that exposes an image to a broader audience puts the container at risk of being hijacked. One of the primary ways this occurs is by using out-of-date software. Using old software gives malicious actors a small incongruence that they can exploit within the code. Another problem is poorly defined user access roles. If sensible changes aren’t made to an orchestration tool’s default settings, inappropriate parties may have access to alter the container’s core executable. Containerization gives you a way to manage a large number of processes easily and with increased adaptability. As a result, automation makes it impossible to keep your eyes on everything at once. Here are some best practices that can help you counter the wide range of vulnerabilities inherent to containerization and Kubernetes in general. Kubernetes Security Best Practices Given the architecture of the Kubernetes framework, security risks are a constant and evolving threat. Luckily, Google made Kubernetes an open-source application under the auspices of the Cloud Native Computing Foundation where solutions to new security issues are actively crowdsourced by the community. Regardless, there are a number of things that you can do during the build, deployment, and runtime phases to make your Kubernetes implementation more secure. Take care of your images Images are the heart of every container. Executable functions are essential, so images must be well-maintained and in good working order. Only use up-to-date images, scanning them regularly for security issues. As a rule of thumb, you should also avoid including unnecessary tools and functions in your image coding as they can inadvertently give hackers an access route. Ensure that your secrets remain secret The term “secrets” refers to any private information such as login credentials, tokens, or other sensitive data. While it’s not customary to keep sensitive data stored adjacent to the container’s image, the scenario has come up before. Keep secret data as far from the image as possible in order to increase security. Keep up-to-date with scans and security patches The community does a good job of patching Kubernetes when issues arise. If you don’t take the time to update both your OS and Kubernetes’ security, you give malware additional avenues of attack. Updates should be performed at least every nine months, if not more often. Due to the nature of how Kubernetes works, if you are using an outdated version, you could actively be spreading issues when the container is deployed elsewhere. Take advantage of customization to define user roles and access A container orchestration tool like Kubernetes is a complex web running thousands of processes across numerous machines. That means hundreds of end-users involved with the application. Take advantage of Kubernetes administrative functions to clearly define user roles, limiting full access for those who don’t need it. As they say, too many cooks spoil the broth. Keeping Kubernetes Simple and Safe Containers are an agile, lightweight framework for cloud computing, but manually deploying the correct containers to their destinations can quickly become overwhelming. An orchestration tool like Kubernetes is the perfect solution to managing your containerization, but the security risks inherent to this model can be restrictive. By keeping a few key practices in mind when implementing Kubernetes into your workflow, you can help to promote safety while streamlining your processes. To Sum It All Up Kubernetes has become the centrepiece of the cloud Native landscape and a notable advantage for organizations to rapidly manage and deploy their containerized business logic. But certain security best practices must be followed such as working with reliable docker images, properly defined resource quotas, network policies, work with namespaces for access control and authentication\authorization, and more.

Firewall Policy Management What is Network Security Policy Automation? Tsippi Dach 6 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published Security policy automation is the process of automating certain cybersecurity tasks like threat detection (ransomware, malware, security rules, network changes), investigation, and remediation. Automating such practices reflects in the policy that governs them. Thus, security policy automation is the process of automating network security controls using a programmatic solution. In present-day security operation centers (SOCs), NSPM solutions can facilitate automation. These work by identifying vulnerabilities, threats, and attack surfaces in the security posture, assessing them, prioritizing them, responding to them in order through pre-defined actions, and streamlining the process for the security executives. So, automation doesn’t mean everything from end to end is automated. Some human intervention may be necessary, at least at the higher decision-making level. Benefits of network security policy automation Automation in security policy has several benefits for an organization. Thus, it’s not hard to see why companies are pumping money into network security automation solutions . Some of the proven benefits are: Automate manual tasks in cybersecurity The primary benefit of any automation practice is to reduce manual labor. Connectivity security automation frees up resources from many redundant manual tasks, which you can then deploy elsewhere. This automation yields several other benefits that make automation irresistible for companies. Bring down false positive alerts False positive alerts or alarms are those instances where the cloud security system gets triggered because of a false threat, like firewall rules . In other words, the management platform perceives certain actions to be threatening, which actually are harmless. This consumes unnecessary resources. IT teams can prevent such real-time false alerts by making use of regulatory automation. Automation tools can detect and verify such alarms and take pre-defined actions should the alerts be false. Consider it a second check before raising the issue at a higher level. Reduce downtime Downtime is one of the pressing issues in IT departments. A study by Gartner penned the average cost of downtime at $5,600 per minute for certain businesses. When the system detects a threat, it typically shuts down certain network segments (like web services, routers, and so on). This can result in downtime. Some downtimes might be unavoidable, but those arising from false positive alerts certainly are. Thus, network security policy automation helps in that regard too. Reduce headcount There’s a shortage of talent in the cybersecurity And often, competent men and women demand sky-high salaries. So, from an economic standpoint, using automation to counter the lack of talent makes sense. With automation, you can divert human resources to other productive tasks. Make compliance easier Compliance is critical for businesses, especially in critical insurance, medical, and legal sectors. Up-to-date infrastructure comprising of Cisco, AWS, Tufin , and other reputed companies with the latest cybersecurity measures is one of the prerequisites laid out by most regulators. Network security policy automation can help update the infrastructure to the latest standards. This, in turn, helps the business stay compliant. Why is automation still a challenge in network security? Despite all its promises and proven benefits, many companies are reluctant to invest in security automation And the reason is it’s challenging to do so. Automation is hard because management itself is hard. You can’t automate something you can’t fully manage properly. E mployees, teams, and projects change, as do the access control Because of such a dynamic environment, automation is still challenging. Another reason is teams tend to work in silos. Multiple stakeholders are involved, including the customers, who must understand and accept the changes. Automation in such instances, known as Deploy and Configure, remains a challenge. But despite the challenges, there are ways to automate multi-vendor on-premises network security Even if you successfully automate some aspects of the policy, it’d be a huge time and resource saver. How to automate network security policy management? Cloud-based security policy automation has been around for quite some time. It has received upgrades over time and has gotten better. Let’s look at present-day automation practices, change processes, and troubleshooting tips. Review the current policy You can’t start from scratch, especially if you have an existing network security policy . The best approach is to start automation from where you are. This way, your security teams do not need to make drastic changes, which may put your network in a more vulnerable state. So as a first step, review your existing cloud environments policy and establish needs. Post that, formulate a plan on which things you can automate and which require manual intervention. Start with things that can be automated. If starting from starch, you must create a security policy first. So, hire cybersecurity experts from AlgoSec to formulate and optimize a policy for your organization’s hybrid network. You can also use Prevasio CNAPP to manage the multi-cloud security You might also want to conduct a webinar if important stakeholders work remotely. The idea is to bring everyone on the same page. Select the type of security automation tools There are three types of hybrid environment security automation tools to choose from. These are no-code, low-code, and full-code automation. The type of automation you select will impact your security policy changes . Pricing of each tool will also play an important role. No-code security automation is the newest type. As the name suggests, such tools do not require coding to automate network security . There are several use cases and pre-made workflows that you can use right off the bat. These are much easier to manage but don’t grant you complete control over the policy. You can have several automation tools within low-code tools like some-code or more-code. Most businesses prefer these security tools since they offer a balance of user-friendliness and robust coding capabilities. You can change and apply the pre-defined use cases to your company’s security policy. Finally, you have full-code automation AlgoBot , for instance, is an intelligent chatbot for handling network security policy management tasks. These are legacy security orchestration, automation, and response (SOAR) platforms. A high level of coding work is necessary to work with these full-code firewall management tools, which poses a high barrier to entry. But the upside is you get full control over the policy. Adopt zero-touch change management Truth be told, you can’t automate 100% of the security policy. Skilled personnel will still be needed to look over everything. However, for those manual tasks, you need speed while still upholding the security principles. How do you balance both? With zero-touch change management. Zero-touch orchestration is an alternative to semi-automated security processes. Vulnerability management accelerates change requests, reducing the time it takes to implement requests to minutes. Despite the speed advantage, zero-touch orchestration has flaws. For example, it accepts the requests as-is and doesn’t check their validities. This can result in misconfiguration. For security risk mitigation , you can embed conditional logic into the orchestration and leverage security and speed. This form of automation will ensure none of the process steps are missed in the lifecycle. FireFlow provides automated security policy management, helping you confidently automate security policy change process. Establish priorities Deploying automation tools is one part done. The next part is adopting the best practices and organizing your team. One of the best practices of policy automation is to establish priorities. Finding the DevOps issues that are more critical to your security needs is imperative. Then place them higher for the team to address them. This requires you to look at your overall network posture (which you have done in the first step). Once you’ve established clear priorities, you should define the use cases and implement workflow automation. Train team members Last, to ensure continuous compliance, you must upskill your team members to grasp the implemented changes. The transition from manual to automated will be challenging for employees too. Make them understand why it’s being done and what they’re supposed to do. This is done through a combination of courses and practical knowledge. Besides the knowledge, they should also clarify where the machine’s capabilities end and human responsibility begins. Once automated, it will take some time for the team to get familiarized with it. For the best results, automate the workflow in batches and not the entire network at once. Develop the playbook along the way and get everyone on the same page. Once you get a tempo, invest in third-party tools and vendors to speed up the automation What’s next? Network security policy automation makes compliance easier, reduces downtime, and automates manual tasks in cybersecurity. However, automation still means having the right tools and professionals within reach.
