success stories “AlgoSec helps us be vendor-agnostic and understand our full security posture to lead us down this journey to achieve zero-trust.” Scott Theriault, Global Manager Network Perimeter Security NCR Corporation Background NCR Corporation is a leading global point-of-sale (POS) provider for restaurants, retailers, and banks and a provider of multi-vendor ATM software. Headquartered in Atlanta, Georgia, NCR has over 36,000 employees in 160 countries, and solutions are distributed in 141 countries. As NCR expands into public cloud platforms such as AWS, they require consistent visibility and security policy management across both on-premises and cloud environments. The challenge NCR needed to connect its DevOps pipeline with its network security. With over 4,500 policy changes made annually, it was difficult to securely manage their entire networking and security environment while being responsive to application owners but still achieve zero trust. Strategically, they were aiming to automate and orchestrate security policy changes across their entire hybrid network, so they could securely accelerate application delivery. As applications and services moved into AWS, NCR also needed unified governance across physical firewalls, Cisco ACI, and cloud-native controls such as AWS Security Groups and AWS Network Firewall. The solution They implemented the AlgoSec Security Policy Management Solution, made up of AlgoSec Firewall Analyzer, AlgoSec FireFlow, and AlgoSec AppViz and AppChange. This solution is now part of AlgoSec Horizon, which also includes AlgoSec Cloud Enterprise (ACE) for cloud-native visibility and policy management . AlgoSec Firewall Analyzer enables organizations to discover, identify, and map business applications across their entire hybrid network. It analyzes complex network security policies across the network. It automates and simplifies security operations, including troubleshooting, auditing, and risk analysis. AlgoSec FireFlow enables security staff to automate the entire security policy change process from design and submission to proactive risk analysis, implementation, validation, and auditing. Its intelligent, automated workflows save time and improve security by eliminating manual errors and reducing risk. AlgoSec AppViz, the application visibility add-on for AlgoSec Firewall Analyzer, provides visibility for your network applications, enabling secure application delivery. AlgoSec AppChange, the application automation add-on for AlgoSec FireFlow, allows for changes at the business application level, including during the application migrations, server deployment, and decommissioning projects. With ACE, NCR also gains visibility into AWS environments, including VPCs, Transit Gateways, Security Groups, and AWS Network Firewall, ensuring consistent zero-trust controls across their hybrid network. The results AlgoSec is a strategic component of NCR’s network security, managing its entire network security infrastructure. The AlgoSec platform enables the NCR Corporation to manage application connectivity end-to-end across their network — including public cloud, Cisco ACI, and physical firewalls. With AlgoSec Horizon and ACE, NCR now extends this visibility into AWS cloud environments, unifying security policy management across firewalls, Cisco ACI, and AWS-native controls such as Security Groups and AWS Network Firewall. “Most products don’t understand the end-to-end environment. AlgoSec does,” noted Scott Theriault, Global Manager, Network Perimeter Security. Some of the ways that NCR Corporation benefits from AlgoSec include: Launched migration of their on-premises data centers into the Cisco ACI fabric. Extended micro-segmentation to Cisco ACI environment. Extended segmentation and zero-trust policy enforcement into AWS cloud architectures. Achieved complete visibility of their global security posture from a single dashboard. Automated risk analysis, achieving visibility and insights into the risk that changes introduce. Streamlined auditing process with to automatic logging and audit-ready compliance reports. Cleaned up and reduced firewall policies with rule cleanup, object cleanup, and policy tuning. Unified governance across on-prem, ACI, and AWS environments to support consistent zero-trust policy controls. “As we aspire to achieve zero-trust, when moving into the cloud, micro-segmentation and container security come into play. Therefore, we need tools like AlgoSec to assist us in the journey because most application owners don’t know what access is needed. This tool helps them learn what needs to be implemented to reduce the attack surface,” stated Theriault. Schedule time with one of our experts

The Challenge SecureLink has been an on-site consultant for several years for a large global entertainment company. SecureLink’s client has over 100 firewalls running both on-premises and on AmazonWeb Services (AWS) from several different vendors. Some of the challenges included: “Shadow IT” had taken over, causing security risks and friction with IT, who had to support it. Security policies were being managed in tedious and unmaintainable Excel spreadsheets Lack of verification if official firewall policies accurately reflected traffic flows The business units were pushing a migration to a hybrid cloud environment rather than relying exclusively on an on-premises deployment. Business units were unilaterally moving business applications to the cloud, leading to “shadow IT.” Business application owners were unable to comply with security policies, troubleshoot their “shadow network,” nor connect cloud-based servers to local servers. When there were problems, the business units went back to the IT department, who had to fix a mess they didn’t create. The Solution SecureLink was searching for a solution that provided: Automation of security policy change management and documentation of security policy changes Comprehensive firewall support for their multi-vendor, hybrid estate Ability to determine compliance and risk profiles Full visibility and control for IT, while enabling business agility In order to keep the business happy and agile, but ensure that IT had full visibility and control, they implemented AlgoSec. The client selected AlgoSec’s Security Policy Management Solution, which includes AlgoSec Firewall Analyzer and AlgoSec FireFlow. AlgoSec Firewall Analyzer delivers visibility and analysis of complex network security policies across on-premise, cloud, and hybrid networks. It automates and simplifies security operations including troubleshooting, auditing, and risk analysis. Using Firewall Analyzer, SecureLink can optimize the configuration of firewalls, and network infrastructure to ensure security and compliance. AlgoSec FireFlow enables security staff to automate the entire security policy change process from design and submission to proactive risk analysis, implementation, validation, and auditing. Its intelligent, automated workflows save time and improve security by eliminating manual errors and reducing risk. The Results AlgoSec helped SecureLink gain control of shadow IT without slowing down the business. By using AlgoSec to gain full visibility of the entire network, IT was able to regain control over company’s security policy while supporting the move to the cloud. “AlgoSec lets us take ownership and be quick for the business,” said Björn Löfman, a consultant at SecureLink. “The way AlgoSec provides the whole map of the internal and cloud networks is outstanding, and to be able to apply the same policy on all your infrastructure is priceless.” By using the AlgoSec Security Management Solution, SecureLink was able to clean up risky firewall policies, gain increased understanding of their security policies, tighten compliance, and enhance migrations of hardware and implement a hybrid cloud environment with Amazon Web Services (AWS). Some benefits to the client of AlgoSec include: Greater understanding of network security policies Easier firewall migration – they migrated from Juniper NetScreen to Check Point firewalls Ability to optimize rules and reduce unneeded and duplicate rules and objects. They were able to go from 4,000 rules to 1,110 rules – a 72% reduction. Move to the hybrid cloud with the adoption of Amazon Web Services Able to reduce shadow IT and reclaim ownership of the cloud Full visibility of entire hybrid network – including both on-premise and devices in the cloud including firewalls, AWS security groups , and Access Control Lists (ACLs).

Cyber Attacks & Incident Response Resolving human error in application outages: strategies for success Malynnda Littky-Porath 2 min read Malynnda Littky-Porath 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 3/18/24 Published Application outages caused by human error can be a nightmare for businesses, leading to financial losses, customer dissatisfaction, and reputational damage. While human error is inevitable, organizations can implement effective strategies to minimize its impact and resolve outages promptly. In this blog post, we will explore proven solutions for addressing human error in application outages, empowering businesses to enhance their operational resilience and deliver uninterrupted services to their customers. Organizations must emphasize training and education One of the most crucial steps in resolving human error in application outages is investing in comprehensive training and education for IT staff. By ensuring that employees have the necessary skills, knowledge, and understanding of the application environment, organizations can reduce the likelihood of errors occurring. Training should cover proper configuration management, system monitoring, troubleshooting techniques, and incident response protocols. Additionally, fostering a culture of continuous learning and improvement is essential. Encourage employees to stay up to date with the latest technologies, best practices, and industry trends through workshops, conferences, and online courses. Regular knowledge sharing sessions and cross-team collaborations can also help mitigate human errors by fostering a culture of accountability and knowledge transfer. It’s time to implement robust change management processes Implementing rigorous change management processes is vital for preventing human errors that lead to application outages. Establishing a standardized change management framework ensures that all modifications to the application environment go through a well-defined process, reducing the risk of inadvertent errors. The change management process should include proper documentation of proposed changes, a thorough impact analysis, and rigorous testing in non-production environments before deploying changes to the production environment. Additionally, maintaining a change log and conducting post-implementation reviews can provide valuable insights for identifying and rectifying any potential errors. Why automate and orchestrate operational tasks Human errors often occur due to repetitive, mundane tasks that are prone to oversight or mistakes. Automating and orchestrating operational tasks can significantly reduce human error in application outages. Organizations should leverage automation tools to streamline routine tasks such as provisioning, configuration management, and deployment processes. By removing the manual element, the risk of human error decreases, and the consistency and accuracy of these tasks improve. Furthermore, implementing orchestration tools allows for the coordination and synchronization of complex workflows involving multiple teams and systems. This reduces the likelihood of miscommunication and enhances collaboration, minimizing errors caused by lack of coordination. Establish effective monitoring and alerting mechanisms Proactive monitoring and timely alerts are crucial for identifying potential issues and resolving them before they escalate into outages. Implementing robust monitoring systems that capture key performance indicators, system metrics, and application logs enables IT teams to quickly identify anomalies and take corrective action. Additionally, setting up alerts and notifications for critical events ensures that the appropriate personnel are notified promptly, allowing for rapid response and resolution. Leveraging artificial intelligence and machine learning capabilities can enhance monitoring by detecting patterns and anomalies that human operators might miss. Human errors will always be a factor in application outages, but by implementing effective strategies, organizations can minimize their impact and resolve incidents promptly. Investing in comprehensive training, robust change management processes, automation and orchestration, and proactive monitoring can significantly reduce the likelihood of human error-related outages. By prioritizing these solutions and fostering a culture of continuous improvement, businesses can enhance their operational resilience, protect their reputation, and deliver uninterrupted services to their customers.

Tags Share this article 12/1/20 Published Yitzy Tannenbaum, Product Marketing Manager at AlgoSec, discusses how AWS customers can leverage AlgoSec for AWS to easily migrate applications Public cloud platforms bring a host of benefits to organizations but managing security and compliance can prove complex. These challenges are exacerbated when organizations are required to manage and maintain security across all controls that make up the security network including on-premise, SDN and in the public cloud. According to a Gartner study , 81% of organizations are concerned about security, and 57% about maintaining regulatory compliance in the public cloud. AlgoSec’s partnership with AWS helps organizations overcome these challenges by making the most of AWS’ capabilities and providing solutions that complement the AWS offering, particularly in terms of security and operational excellence. And to make things even easier, AlgoSec is now available in AWS Marketplace. Accelerating complex application migration with AlgoSec Many organizations choose to migrate workloads to AWS because it provides unparalleled opportunities for scalability, flexibility, and the ability to spin-up new servers within a few minutes. However, moving to AWS while still maintaining high-level security and avoiding application outages can be challenging, especially if you are trying to do the migration manually, which can create opportunities for human error. We help simplify the migration to AWS with a six-step automated process, which takes away manual processes and reduces the risk of error: Step 1 – AlgoSec automatically discovers and maps network flows to the relevant business applications. Step 2- AlgoSec assesses the changes in the application connectivity required to migrate it to AWS. Step 3- AlgoSec analyzes, simulates and computes the necessary changes, across the entire hybrid network (over firewalls, routers, security groups etc.), including providing a what-if risk analysis and compliance report. Step 4- AlgoSec automatically migrates the connectivity flows to the new AWS environment. Step 5 – AlgoSec securely decommissions old connectivity. Step 6- The AlgoSec platform provides ongoing monitoring and visibility of the cloud estate to maintain security and operation of policy configurations or successful continuous operation of the application. Gain control of hybrid estates with AlgoSec Security automation is essential if organizations are to maintain security and compliance across their hybrid environments, as well as get the full benefit of AWS agility and scalability. AlgoSec allows organizations to seamlessly manage security control layers across the entire network from on-premise to cloud services by providing Zero-Touch automation in three key areas. First, visibility is important, since understanding the network we have in the cloud helps us to understand how to deploy and manage the policies across the security controls that make up the hybrid cloud estate. We provide instant visibility, risk assessment and compliance, as well as rule clean-up, under one unified umbrella. Organizations can gain instant network visibility and maintain a risk-free optimized rule set across the entire hybrid network – across all AWS accounts, regions and VPC combinations, as well as 3rd party firewalls deployed in the cloud and across the connection to the on-prem network. Secondly, changes to network security policies in all these diverse security controls can be managed from a single system, security policies can be applied consistently, efficiently, and with a full audit trail of every change. Finally, security automation dramatically accelerates change processes and enables better enforcement and auditing for regulatory compliance. It also helps organizations overcome skill gaps and staffing limitations. Why Purchase Through AWS Marketplace? AWS Marketplace is a digital catalog with thousands of software listings from independent software vendors (ISVs). It makes it easy for organizations to find, test, buy, and deploy software that runs on Amazon Web Services (AWS), giving them a further option to benefit from AlgoSec. The new listing also gives organizations the ability to apply their use of AlgoSec to their AWS Enterprise Discount Program (EDP) spend commitment. With the addition of AlgoSec in AWS Marketplace, customers can benefit from simplified sourcing and contracting as well as consolidated billing, ultimately resulting in cost savings. It offers organizations instant visibility and in-depth risk analysis and remediation, providing multiple unique capabilities such as cloud security group clean-ups, as well as central policy management.

Cloud Security Operation “Red Kangaroo”: Industry’s First Dynamic Analysis of 4M Public Docker Container Images Rony Moshkovich 2 min read Rony Moshkovich 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 12/1/20 Published Linux containers aren’t new. In fact, this technology was invented 20 years ago. In 2013, Docker entered the scene and revolutionized Linux containers by offering an easy-to-use command line interface (CLI), an engine, and a registry server. Combined, these technologies have concealed all the complexity of building and running containers, by offering one common industry standard . As a result, Docker’s popularity has sky-rocketed, rivalling Virtual Machines, and transforming the industry. In order to locate and share Docker container images, Docker is offering a service called Docker Hub . Its main feature, repositories , allows the development community to push (upload) and pull (download) container images. With Docker Hub, anyone in the world can download and execute any public image, as if it was a standalone application. Today, Docker Hub accounts over 4 million public Docker container images . With 8 billion pulls (downloads) in January 2020 and growing , its annualized image pulls should top 100 billion this year. For comparison , Google Play has 2.7M Android apps in its store, with a download rate of 84 billion downloads a year. How many container images currently hosted at Docker Hub are malicious or potentially harmful? What sort of damage can they inflict? What if a Docker container image downloaded and executed malware at runtime? Is there a reliable way to tell that? What if a compromised Docker container image was downloaded by an unsuspecting customer and used as a parent image to build and then deploy a new container image into production, practically publishing an application with a backdoor built into it? Is there any way to stop that from happening? At Prevasio, we asked ourselves these questions multiple times. What we decided to do has never been done before. The Challenge At Prevasio, we have built a dynamic analysis sandbox that uses the same principle as a conventional sandbox that ‘detonates’ malware in a safe environment. The only difference is that instead of ‘detonating’ an executable file, such as a Windows PE file or a Linux ELF binary, Prevasio Analyzer first pulls (downloads) an image from any container registry, and then ‘detonates’ it in its own virtual environment, outside the organization/customer infrastructure. Using our solution, we then dynamically analyzed all 4 million container images hosted at Docker Hub. In order to handle such a massive volume of images, Prevasio Analyzer was executed non-stop for a period of one month on 800 machines running in parallel. The result of our dynamic scan reveals that: 51 percent of all containers had “critical” vulnerabilities, while 13 percent were classified as “high” and four percent as “moderate” vulnerabilities. Six thousand containers were riddled with cryptominers, hacking tools/pen testing frameworks, and backdoor trojans. While many cryptominers and hacking tools may not be malicious per se, they present a potentially unwanted issue to an enterprise. More than 400 container images (with nearly 600,000 pulls) of weaponized Windows malware crossing over into the world of Linux. This crossover is directly due to the proliferation of cross-platform code (e.g. GoLang, .NET Core and PowerShell Core). Our analysis of malicious containers also shows that quite a few images contain a dynamic payload. That is, an image in its original form does not have a malicious binary. However, at runtime, it might be scripted to download a source of a coinminer, to then compile and execute it. A dynamic analysis sandbox, such as Prevasio Analyzer, is the only solution that provides a behavioral analysis of Docker containers. It is built to reveal malicious intentions of Docker containers by executing them in its own virtual environment, revealing a full scope of their behavior. The whitepaper with our findings is available here . Schedule a demo Related Articles 2025 in review: What innovations and milestones defined AlgoSec’s transformative year in 2025?

What are firewall logs and why they are important Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. What are firewall logs and why are they important? Network setups of the past consisted solely of servers in a server closet. Today, modern IT infrastructure consists of three main components: on-premises data centers, public clouds, and their connecting infrastructure. This new reality has created complex systems with multiple challenges. Regulations have become stricter, and organizations are under pressure to detect security threats fast. When faced with an issue, network security professionals must pinpoint the root cause, and to do that, they need evidence—which means investigating firewall logs. What is a firewall log? A firewall log is a record of the network connections (allowed and blocked) that a firewall inspects, capturing each event between your systems and the internet. Depending on the configuration, a firewall log may include all inspected traffic or only what the firewall allows to pass into the environment (what “gets past” the firewall). Each entry of a firewall log will specify the following data: Field Description Timestamp Exact date and time traffic was processed Action Decision made by the firewall (Allow, Deny, Drop) Rule ID Specific firewall rule that triggered the action Source IP & Port IP address and port from where traffic originated Destination IP & Port IP address and port that the traffic was trying to reach Protocol Network protocol used (TCP, UDP, ICMP) Bytes/Session Amount of data transferred during a session Zones Source and destination security zones (Trust, Untrust, DMZ) Beyond the question of “What is a firewall log?” there is also the question of where to store them. Organizations have a few options here. Firewall logs can: Stay on the firewall device Go to a basic syslog server for storage Undergo analysis via a security information and event management (SIEM) tool What is a firewall review? The process of reviewing a firewall is akin to a scheduled maintenance procedure that updates the rulebook of your firewall system. Things to be on the lookout for include: Duplicate rules Outdated server rules Overly broad rules that can lead to security vulnerabilities What is a firewall log review? Ready to play detective? Because a firewall log review requires just that. Analyzing firewall data is a continuous process of extracting relevant information from the firewall logs, i.e., the firewall’s own journal of events.. The key is to identify specific patterns that indicate security incidents, performance issues, or non-compliance events. This, in turn, requires centralizing logs with synchronized device clocks so that timelines line up (i.e., NTP across firewalls, servers, and your SIEM) and putting controls in place to preserve log integrity. How to interpret firewall logs in 6 steps So now that it is clear what a firewall log is—as well as how to store these logs and review them—the next step is knowing how to interpret them. Successfully extracting the necessary data from your firewall logs is a six-step process: Collect logs in one place: The central system needs to receive logs from all firewalls that extend from the data center to the cloud. Each entry missing from your logs allows malicious actors to remain unseen, i.e., pose an unknown threat.. Figure out what's normal: To detect abnormal behavior, you must first create a baseline for normal activity, i.e., typical traffic patterns. Hunt for suspicious patterns: The official investigation begins! What to flag? Network scanning activity from a single IP address that attempts to access multiple ports and internal devices and makes scheduled connections to unverified external servers (beaconing). Add context: Context turns raw events into decisions. Enrich IPs and ports from your logs with: Asset inventory: What system and business app is this? User directories: Who owns/uses it? Threat intelligence: Is the source/destination risky? This enrichment helps determine impact and priority—not just “who/what,” but whether the activity is expected, whether the system is critical, and how urgently you need to respond. Investigate and act: Trigger an incident response plan: Validate findings Contain the incident (isolate the host, block indicators at the firewall). Collect forensics (packet captures, memory snapshot, log preservation) Eradicate the threat Recover systems, operations, and data (patches, credential resets, rule updates) Notify stakeholders Document the case for post‑incident review. Measure and improve: Learn from your results. Identify rules that are creating too much noise and clean them up. Most importantly, track how long it takes you to respond to incidents you find in your logs. How does AlgoSec help with firewall logs?
