success stories "Today, we are many times more efficient and secure thanks to AlgoSec." Background The company’s globally distributed network includes more than ten demilitarized zones (DMZs) with 20 billion events processed per month across the multiple company locations. Firewalls play a vital role in protecting intellectual property at the perimeter level. Every firewall event is logged and processed. Challenges The company’s operations require a very large and diverse network with a large Global Network Security operations team that is spread across the US, EMEA and Asia. The team is responsible for the management of all perimeter and internal security solutions, remote access solutions, customer connectivity solutions and the Security Operations Center (SOC). “We suffered from a lot of network security issues that prevented us from running at the speed of the business,” declared the Senior Manager of Global Security and SOC. Auditing Firewall rules was a long, tedious and painful process Access revocation was performed using a manual reminders process The diverse army of firewalls across the network estate resulted in a non-standard way of making and executing Firewall change requests, requiring many steps to complete the process An out-of-the-box ServiceNow workflow with limited functionality couldn’t keep up Limited reporting capabilities relied on manual data processing There was no way to track performance of SLAs The cumbersome approval process required managers to login to the company ticketing portal Notification of unauthorized or unapproved changes on firewalls was clumsy and slow The company decided to acquire an orchestration and automation solution that could identify and mitigate risky firewall rules. Since the company is subject to many industry and legal regulations, the solution would have to automate compliance reporting as well as ensure accountability for all firewall changes. The solution also would have to integrate into existing ticketing processes and workflows while enabling the company, at its own pace, to advance to more and more automation. Solution The company evaluated several solutions by reviewing their features carefully and putting the best among them to the test in parallel proof of concept projects. The senior manager recalls, “We had a very close look at the leading solutions in the Network Security Policy Management space. One of them definitely stood out from the pack as the superior solution.” The company chose AlgoSec Horizon Security Analyzer (AFA) and AlgoSec Horizon FireFlow (AFF), two of the flagship products in the AlgoSec arsenal. AlgoSec Horizon Security Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec Horizon FireFlow improves security and saves security staffs’ time by automating the entire security policy change process, eliminating manual errors, and reducing risk. Results In short order, the company was able to capitalize on the significant advantages of the AlgoSec solution. “It was easy to customize the AlgoSec solution to fit into our environment and enhance it,” continued the senior manager. “But it didn’t take long before we were using the power of the two products to help us adopt better practices for lower risk, higher security, and better efficiency of our team.” Today, the AlgoSec solution is delivering significant improvements to the company’s security processes such as: Visibility across the entire network with an easy-to-use-and-understand executive dashboard Integration with the ticketing tool Proactive analysis of change requests to ensure compliance risk mitigation Prevention of unauthorized changes Elimination of human errors and associated application outages Automatic discovery and mapping of application-connectivity flows Single Sign On (SSO) integration that eliminated static user passwords Support for mobile firewall change-request manager approval “We are a big company with an enormous volume of network-security activity,” stated the manager. “In addition to the superior capabilities of the solution, we greatly appreciated the excellent customization opportunities that AlgoSec’s Professional Services were able to help us with. Today, we are many times more efficient and secure thanks to AlgoSec.” Schedule time with one of our experts

Auditing and Compliance Compliance Made Easy: How to improve your risk posture with automated audits Tal Dayan 2 min read Tal Dayan 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 4/29/21 Published Tal Dayan, security expert for AlgoSec, discusses the secret to passing audits seamlessly and how to introduce automated compliance Compliance standards come in many different shapes and sizes. Some organizations set their own internal policies, while others are subject to regimented global frameworks such as PCI DSS , which protects customers’ card payment details; SOX to safeguard financial information or HIPAA , which protects patients’ healthcare data. Regardless of which industry you operate in, regular auditing is key to ensuring your business retains its risk posture whilst also remaining compliant. The problem is that running manual risk and security audits can be a long, drawn-out, and tedious affair. A 2020 report from Coalfire and Omdia  found that for the majority of organizations, growing compliance obligations are now consuming 40% or more of IT security budgets and threaten to become an unsustainable cost.  The report suggests two reasons for this growing compliance burden.  First, compliance standards are changing from point-in-time reviews to continuous, outcome-based requirements. Second, the ongoing cyber-skills shortage is stretching organizations’ abilities to keep up with compliance requirements. This means businesses tend to leave them until the last moment, leading to a rushed audit that isn’t as thorough as it could be, putting your business at increased risk of a penalty fine or, worse, a data breach that could jeopardize the entire organization. The auditing process itself consists of a set of requirements that must be created for organizations to measure themselves against. Each rule must be manually analyzed and simulated before it can be implemented and used in the real world. As if that wasn’t time-consuming enough, every single edit to a rule must also be logged meticulously. That is why automation plays a key role in the auditing process. By striking the right balance between automated and manual processes, your business can achieve continuous compliance and produce audit reports seamlessly. Here is a six-step strategy that can set your business on the path to sustainable and successful ongoing auditing preservation: Step 1: Gather information This step will be the most arduous but once completed it will become much easier to sustain. This is when you’ll need to gather things like security policies, firewall access logs, documents from previous audits and firewall vendor information – effectively everything you’d normally factor into a manual security audit. Step 2: Define a clear change management process A good change management process is essential to ensure traceability and accountability when it comes to firewall changes. This process should confirm that every change is properly authorized and logged as and when it occurs, providing a picture of historical changes and approvals. Step 3: Audit physical & OS security With the pandemic causing a surge in the number of remote workers and devices used, businesses must take extra care to certify that every endpoint is secured and up-to-date with relevant security patches. Crucially, firewall and management services should also be physically protected, with only designated personnel permitted to access them. Step 4: Clean up & organize rule base As with every process, the tidier it is, the more efficient it is. Document rules and naming conventions should be enforced to ensure the rule base is as organized as possible, with identical rules consolidated to keep things concise. Step 5: Assess & remediate risk Now it’s time to assess each rule and identify those that are particularly risky and prioritize them by severity. Are there any that violate corporate security policies? Do some have “ANY” and a permissive action? Make a list of these rules and analyze them to prepare plans for remediation and compliance. Step 6: Continuity & optimization Now it’s time to simply hone the first five steps and make these processes as regular and streamlined as possible. By following the above steps and building out your own process, you can make day-to-day compliance and auditing much more manageable. Not only will you improve your compliance score, you’ll also be able to maintain a sustainable level of compliance without the usual disruption and hard labor caused by cumbersome and expensive manual processes.

Yes, Here’s 6 Vulnerabilities Tsippi Dach 2 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 12/20/23 Published Can Firewalls Be Hacked? Yes, Here’s 6 Vulnerabilities Like all security tools, firewalls can be hacked. That’s what happened to the social media platform X in January 2023, when it was still Twitter. Hackers exploited an API vulnerability that had been exposed since June the previous year. This gave them access to the platform’s security system and allowed them to leak sensitive information on millions of users. This breach occurred because the organization’s firewalls were not configured to examine API traffic with enough scrutiny. This failure in firewall protection led to the leak of more than 200 million names, email addresses, and usernames, along with other information, putting victims at risk of identity theft . Firewalls are your organization’s first line of defense against malware and data breaches. They inspect all traffic traveling into and out of your network, looking for signs of cyber attacks and blocking malicious activity when they find it. This makes them an important part of every organization’s cybersecurity strategy. Effective firewall management and configuration is vital for preventing cybercrime. Read on to find out how you can protect your organization from attacks that exploit firewall vulnerabilities you may not be aware of. Understanding the 4 Types of Firewalls The first thing every executive and IT leader should know is that there are four basic types of firewalls . Each category offers a different level of protection, with simpler solutions costing less than more advanced ones. Most organizations need to use some combination of these four firewall types to protect sensitive data effectively. Keep in mind that buying more advanced firewalls is not always the answer. Optimal firewall management usually means deploying the right type of firewall for its particular use case. Ideally, these should be implemented alongside multi-layered network security solutions that include network detection and response, endpoint security, and security information and event management (SIEM) technology. 1. Packet Filtering Firewalls These are the oldest and most basic types of firewalls. They operate at the network layer, checking individual data packets for their source IP address and destination IP. They also verify the connection protocol, as well as the source port and destination port against predefined rules. The firewall drops packets that fail to meet these standards, protecting the network from potentially harmful threats. Packet filtering firewalls are among the fastest and cheapest types of firewalls available. Since they can not inspect the contents of data packets, they offer minimal functionality. They also can’t keep track of established connections or enforce rules that rely on knowledge of network connection states. This is why they are considered stateless firewalls. 2. Stateful Inspection Firewalls These firewalls also perform packet inspection, but they ingest more information about the traffic they inspect and compare that information against a list of established connections and network states. Stateful inspection firewalls work by creating a table that contains the IP and port data for traffic sources and destinations, and dynamically check whether data packets are part of a verified active connection. This approach allows stateful inspection firewalls to deny data packets that do not belong to a verified connection. However, the process of checking data packets against the state table consumes system resources and slows down traffic. This makes stateful inspection firewalls vulnerable to Distributed Denial-of-Service (DDoS) attacks. 3. Application Layer Gateways These firewalls operate at the application layer, inspecting and managing traffic based on specific applications or protocols, providing deep packet inspection and content filtering. They are also known as proxy firewalls because they can be implemented at the application layer through a proxy device. In practice, this means that an external client trying to access your system has to send a request to the proxy firewall first. The firewall verifies the authenticity of the request and forwards it to an internal server. They can also work the other way around, providing internal users with access to external resources (like public web pages) without exposing the identity or location of the internal device used. 4. Next-Generation Firewalls (NGFW) Next-generation firewalls combine traditional firewall functions with advanced features such as intrusion prevention, antivirus, and application awareness . They contextualize data packet flows and enrich them with additional data, providing comprehensive security against a wide range of threats. Instead of relying exclusively on IP addresses and port information, NGFWs can perform identity-based monitoring of individual users, applications, and assets. For example, a properly configured NGFW can follow a single user’s network traffic across multiple devices and operating systems, providing an activity timeline even if the user switches between a desktop computer running Microsoft Windows and an Amazon AWS instance controlling routers and iOT devices. How Do These Firewalls Function? Each type of firewall has a unique set of functions that serve to improve the organization’s security posture and prevent hackers from carrying out malicious cyber attacks. Optimizing your firewall fleet means deploying the right type of solution for each particular use case throughout your network. Some of the most valuable functions that firewalls perform include: Traffic Control They regulate incoming and outgoing traffic, ensuring that only legitimate and authorized data flows through the network. This is especially helpful in cases where large volumes of automated traffic can slow down routine operations and disrupt operations. For example, many modern firewalls include rules designed to deny bot traffic. Some non-human traffic is harmless, like the search engine crawlers that determine your website’s ranking against certain keyword searches. However, the vast majority of bot traffic is either unnecessary or malicious. Firewalls can help you keep your infrastructure costs down by filtering out connection attempts from automated sources you don’t trust. Protection Against Cyber Threats Firewalls act as a shield against various cyber threats, including phishing attacks, malware and ransomware attacks . Since they are your first line of defense, any malicious activity that targets your organization will have to bypass your firewall first. Hackers know this, which is why they spend a great deal of time and effort finding ways to bypass firewall protection. They can do this by exploiting technical vulnerabilities in your firewall devices or by hiding their activities in legitimate traffic. For example, many firewalls do not inspect authenticated connections from trusted users. If cybercriminals learn your login credentials and use your authenticated account to conduct an attack, your firewalls may not notice the malicious activity at all. Network Segmentation By defining access rules, firewalls can segment networks into zones with varying levels of trust, limiting lateral movement for attackers. This effectively isolates cybercriminals into the zone they originally infiltrated, and increases the chance they make a mistake and reveal themselves trying to access additional assets throughout your network. Network segmentation is an important aspect of the Zero Trust framework. Firewalls can help reinforce the Zero Trust approach by inspecting traffic traveling between internal networks and dropping connections that fail to authenticate themselves. Security Policy Enforcement Firewalls enforce security policies, ensuring that organizations comply with their security standards and regulatory requirements. Security frameworks like NIST , ISO 27001/27002 , and CIS specify policies and controls that organizations need to implement in order to achieve compliance. Many of these frameworks stipulate firewall controls and features that require organizations to invest in optimizing their deployments. They also include foundational and organizational controls where firewalls play a supporting role, contributing to a stronger multi-layered cybersecurity strategy. Intrusion Detection and Prevention Advanced firewalls include intrusion detection and prevention capabilities, which can identify and block suspicious activities in real-time. This allows security teams to automate their response to some of the high-volume security events that would otherwise drag down performance . Automatically detecting and blocking known exploits frees IT staff to spend more time on high-impact strategic work that can boost the organization’s security posture. Logging and Reporting Firewalls generate logs and reports that assist in security analysis, incident response, and compliance reporting. These logs provide in-depth data on who accessed the organization’s IT assets, and when the connection occurred. They enable security teams to conduct forensic investigations into security incidents, driving security performance and generating valuable insights into the organization’s real-world security risk profile. Organizations that want to implement SIEM technology must also connect their firewall devices to the platform and configure them to send log data to their SIEM for centralized analysis. This gives security teams visibility into the entire organization’s attack surface and enables them to adopt a Zero Trust approach to managing log traffic. Common Vulnerabilities & Weaknesses Firewalls Share Firewalls are crucial for network security, but they are not immune to vulnerabilities. Common weaknesses most firewall solutions share include: Zero-day vulnerabilities These are vulnerabilities in firewall software or hardware that are unknown to the vendor or the general public. Attackers can exploit them before patches or updates are available, making zero-day attacks highly effective. Highly advanced NGFW solutions can protect against zero-day attacks by inspecting behavioral data and using AI-enriched analysis to detect unknown threats. Backdoors Backdoors are secret entry points left by developers or attackers within a firewall’s code. These hidden access points can be exploited to bypass security measures. Security teams must continuously verify their firewall configurations to identify the signs of backdoor attacks. Robust and effective change management solutions help prevent backdoors from remaining hidden. Header manipulation Attackers may manipulate packet headers to trick firewalls into allowing unauthorized traffic or obscuring their malicious intent. There are multiple ways to manipulate the “Host” header in HTTP traffic to execute attacks. Security teams need to configure their firewalls and servers to validate incoming HTTP traffic and limit exposure to header vulnerabilities. How Cyber Criminals Exploit These Vulnerabilities Unauthorized Access Exploiting a vulnerability can allow cybercriminals to penetrate a network firewall, gaining access to sensitive data, proprietary information, or critical systems. Once hackers gain unauthorized access to a network asset, only a well-segmented network operating on Zero Trust principles can reliably force them to reveal themselves. Otherwise, they will probably remain hidden until they launch an active attack. Data Breaches Once inside your network, attackers may exfiltrate sensitive information, including customer data, intellectual property, and financial records (like credit cards), leading to data breaches. These complex security incidents can lead to major business disruptions and reputational damage, as well as enormous recovery costs. Malware Distribution Attackers may use compromised firewalls to distribute malware, ransomware, or malicious payloads to other devices within the network. This type of attack may focus on exploiting your systems and network assets, or it may target networks adjacent to your own – like your third-party vendors, affiliate partners, or customers. Denial of Service (DDoS) Exploited firewalls can be used in DDoS attacks, potentially disrupting network services and rendering them unavailable to users. This leads to expensive downtime and reputational damage. Some hackers try to extort their victims directly, demanding organizations pay money to stop the attack. 6 Techniques Used to Bypass Firewalls 1. Malware and Payload Delivery Attackers use malicious software and payloads to exploit firewall vulnerabilities, allowing them to infiltrate networks or systems undetected. This often occurs due to unpatched security vulnerabilities in popular firewall operating systems. For example, in June 2023 Fortinet addressed a critical-severity FortiOS vulnerability with a security patch. One month later in July, there were still 300,000 Fortinet firewalls still using the unpatched operating system. 2. Phishing Attacks Phishing involves tricking individuals into divulging sensitive information or executing malicious actions. Attackers use deceptive emails or websites that may bypass firewall filters. If they gain access to privileged user account credentials, they may be able to bypass firewall policies entirely, or even reconfigure firewalls themselves. 3. Social Engineering Tactics Cybercriminals manipulate human psychology to deceive individuals into disclosing confidential information, effectively bypassing technical security measures like firewalls. This is typically done through social media, email, or by telephone. Attackers may impersonate authority figures both inside and outside the organization and demand access to sensitive assets without going through the appropriate security checks. 4. Deep Packet Inspection Evasion Attackers employ techniques to disguise malicious traffic, making it appear benign to firewalls using deep packet inspection, allowing it to pass through undetected. Some open-source tools like SymTCP can achieve this by running symbolic executions on the server’s TCP implementation, scanning the resulting execution paths, and sending malicious data through any handling discrepancies identified. 5. VPNs and Remote Access Attackers may use Virtual Private Networks (VPNs) and remote access methods to circumvent firewall restrictions and gain unauthorized entry into networks. This is particularly easy in cases where simple geo restrictions block traffic from IP addresses associated with certain countries or regions. Attackers may also use more sophisticated versions of this technique to access exposed services that don’t require authentication, like certain containerized servers . 6. Intrusion Prevention Systems (IPS) Bypass Sophisticated attackers attempt to evade IPS systems by crafting traffic patterns or attacks that go undetected, enabling them to compromise network security. For example, they may use technologies to decode remote access tool executable files hidden inside certificate files, allowing them to reassemble the malicious file after it passes through the IPS. Protecting Against Firewall Vulnerabilities Multi-factor Authentication (MFA) MFA adds an extra layer of security by requiring users to provide multiple forms of identification, such as a password and a one-time code sent to their mobile device, before they gain access. This prevents attackers from accessing sensitive network assets immediately after stealing privileged login credentials. Knowing an account holder’s password and username is not enough. Two-factor Authentication (2FA) 2FA is a subset of MFA that involves using two authentication factors, typically something the user knows (password) and something the user has (a mobile device or security token), to verify identity and enhance firewall security. Other versions use biometrics like fingerprint scanning to authenticate the user. Intrusion Prevention Systems (IPS) IPS solutions work alongside firewalls to actively monitor network traffic for suspicious activity and known attack patterns, helping to block or mitigate threats before they can breach the network. These systems significantly reduce the amount of manual effort that goes into detecting and blocking known malicious attack techniques. Web Application Firewalls (WAF) WAFs are specialized firewalls designed to protect web applications from a wide range of threats, including SQL injection, cross-site scripting (XSS), and other web-based attacks. Since these firewalls focus specifically on HTTP traffic, they are a type of application level gateway designed specifically for web applications that interact with users on the public internet. Antivirus Software and Anti-malware Tools Deploying up-to-date antivirus and anti-malware software on endpoints, servers, and Wi-Fi network routers helps detect and remove malicious software, reducing the risk of firewall compromise. In order to work effectively, these tools must be configured to detect and mitigate the latest threats alongside the organization’s other security tools and firewalls. Automated solutions can help terminate unauthorized processes before attackers get a chance to deliver malicious payloads. Regular Updates and Patch Management Keeping firewalls and all associated software up-to-date with the latest security patches and firmware updates is essential for addressing known vulnerabilities and ensuring optimal security. Security teams should know when configuration changes are taking place, and be equipped to respond quickly when unauthorized changes take place. Implementing a comprehensive visibility and change management platform like AlgoSec makes this possible. With AlgoSec, you can simulate the effects of network configuration changes and proactively defend against sophisticated threats before attackers have a chance to strike. Monitoring Network Traffic for Anomalies Continuous monitoring of network traffic helps identify unusual patterns or behaviors that may indicate a security incident. Anomalies can trigger alerts for further investigation and response. Network detection and response solutions grant visibility into network activities that would otherwise go unnoticed, potentially giving security personnel early warning when unannounced changes or suspicious behaviors take place.

Tags Share this article 10/9/22 Published Hybrid cloud computing enables organizations to deploy sensitive workloads on-premise or in a private cloud, while hosting less business-critical resources on public clouds. But despite its many benefits, the hybrid environment also creates security concerns. AlgoSec’s co-founder and CTO, Prof. Avishai Wool shares his expert insights on these concerns and offers best practices to boost hybrid cloud security. Hybrid cloud computing combines on-premises infrastructure, private cloud services, and one or more public clouds. Going hybrid provides businesses with enhanced flexibility, agility, cost savings, and scalability to innovate, grow, and gain a competitive advantage. So, how can you simplify and strengthen security operations in the hybrid cloud? It all starts with visibility – you still can’t protect what you can’t see To protect their entire hybrid infrastructure, applications, workloads, and data, security teams need to know what these assets are and where they reside. They also need to see the entire hybrid estate and not just the individual elements. However, complete visibility is a serious hybrid cloud security challenge. Hybrid environments are highly complex, which can create security blind spots, which then prevent teams from identifying, evaluating, and most importantly, mitigating risk. Another hybrid cloud security concern is that you cannot implement a fragmented security approach to control the entire network. With thousands of integrated and inter-dependent resources and data flowing between them, vulnerabilities crop up, increasing the risk of cyberattacks or breaches. For complete hybrid cloud security, you need a holistic approach that can help you control the entire network. Is DevSecOps the panacea? Not quite In many organizations, DevSecOps teams manage cloud security because they have visibility into what’s happening inside the cloud. However, in the hybrid cloud, many applications have servers or clients existing outside the cloud, which DevSecOps may not have visibility into. Also, the protection of data flowing into and out of the cloud is not always under their remit. To make up for these gaps, other teams are required to manage security operations and minimize hybrid cloud risks. These additional processes and team members must be coordinated to ensure continuous security across the entire hybrid network environment. But this is easier said than done. Using IaC to balance automation with oversight is key, but here’s why you shouldn’t solely rely on it Infrastructure as code (IaC) will help you automatically deploy security controls in the hybrid cloud to prevent misconfiguration errors, non-compliance, and violations while in the production stage and pre application testing. With IaC-based security, you can define security best practices in template files, which will minimize risks and enhance your security posture. But there’s an inherent risk in putting all your eggs in the automation and IaC basket. Due to the fact that all the controls are on the operational side, it can create serious hybrid cloud security issues. And without human attention and action, vulnerabilities may remain unaddressed and open the door to cyberattacks. Since security professionals who are not on the operational side must oversee the cloud environment, it could easily open the door to miscommunication and human errors – a very costly proposition for organizations. For this very reason, you should also implement a process to regularly deploy automatic updates without requiring time-consuming approvals that slow down workflows and weaken security. Strive for 95% automated changes and only involve a person for the remaining 5% that requires human input. Hybrid cloud security best practices – start early, start strong When migrating from on-prem to the cloud, you can choose a greenfield migration or a lift-and-shift migration. Greenfield means rolling out a brand-new application. In this case, ensure that security considerations are “baked in” from the beginning and across all processes. This “shift left” approach helps build an environment that’s secure from the get-go. This ensures that all team members adhere to a unified set of security policy rules to minimize vulnerabilities and reduce security risks within the hybrid cloud environment. If you lift-and-shift on-prem applications to the cloud, note any security assumptions made when they were designed. This is important because they were not built for the cloud and may incorporate protocols that increase security risks. Next, implement appropriate measures during migration planning. For example, implement an Application Load Balancer if applications leverage plaintext protocols, and use sidecars to encrypt applications without having to modify the original codebase. You can also leverage hybrid cloud security solutions to detect and mitigate security problems in real-time. Matching your cloud security with application structure is no longer optional Before moving to a hybrid cloud, map the business logic, application structure, and application ownership into the hybrid cloud estate’s networking structure. To simplify this process, here are some tried and proven ways to consider. Break up your environment into a virtual private cloud (VPC) or virtual network. With the VPC, you can monitor connections, screen traffic, create multiple subnets, and also restrict instance access to improve security posture. Use networking constructs to segregate applications into different functional and networking areas in the cloud. This way, you can deploy network controls to segment your cloud estate and ensure that only authorized users can access sensitive data and resources. Tag all resources based on their operating system, business unit, and geographical area. Tags with descriptive metadata can help to identify resources. They also establish ownership and accountability, provide visibility into cloud consumption, and help with the deployment of security policies. Conclusion In today’s fast-paced business environment, hybrid cloud computing can benefit your organization in many ways. But to capture these benefits, you should make an effort to boost hybrid cloud security. Incorporate the best practices discussed here to improve security and take full advantage of your hybrid environment.
