    Product Marketing Manager AlgoSec Cloud Navigating Compliance in the Cloud Iris Stein 2 min read Iris Stein 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 6/29/25 Published Cloud adoption isn't just soaring; it's practically stratospheric. Businesses of all sizes are leveraging the agility, scalability, and innovation that cloud environments offer. Yet, hand-in-hand with this incredible growth comes an often-overlooked challenge: the increasing complexities of maintaining compliance. Whether your organization grapples with industry-specific regulations like HIPAA for healthcare, PCI DSS for payment processing, SOC 2 for service organizations, or simply adheres to stringent internal governance policies, navigating the ever-shifting landscape of cloud compliance can feel incredibly daunting. It's akin to staring at a giant, knotted ball of spaghetti, unsure where to even begin untangling. But here’s the good news: while it demands attention and a strategic approach, staying compliant in the cloud is far from an impossible feat. This article aims to be your friendly guide through the compliance labyrinth, offering practical insights and key considerations to help you maintain order and assurance in your cloud environments. The foundation: Understanding the Shared Responsibility Model Before you even think about specific regulations, you must grasp the Shared Responsibility Model . This is the bedrock of cloud compliance, and misunderstanding it is a common pitfall that can lead to critical security and compliance gaps. In essence, your cloud provider (AWS, Azure, Google Cloud, etc.) is responsible for the security of the cloud – that means the underlying infrastructure, the physical security of data centers, the global network, and the hypervisors. However, you are responsible for the security in the cloud . This includes your data, your configurations, network traffic protection, identity and access management, and the applications you deploy. Think of it like a house: the cloud provider builds and secures the house (foundation, walls, roof), but you’re responsible for what you put inside it, how you lock the doors and windows, and who you let in. A clear understanding of this division is paramount for effective cloud security and compliance. Simplify to conquer: Centralize your compliance efforts Imagine trying to enforce different rules for different teams using separate playbooks – it's inefficient and riddled with potential for error. The same applies to cloud compliance, especially in multi-cloud environments. Juggling disparate compliance requirements across multiple cloud providers manually is not just time-consuming; it's a recipe for errors, missed deadlines, and a constant state of anxiety. The solution? Aim for a unified, centralized approach to policy enforcement and auditing across your entire multi-cloud footprint. This means establishing consistent security policies and compliance controls that can be applied and monitored seamlessly, regardless of which cloud platform your assets reside on. A unified strategy streamlines management, reduces complexity, and significantly lowers the risk of non-compliance. The power of automation: Your compliance superpower Manual compliance checks are, to put it mildly, an Achilles' heel in today's dynamic cloud environments. They are incredibly time-consuming, prone to human error, and simply cannot keep pace with the continuous changes in cloud configurations and evolving threats. This is where automation becomes your most potent compliance superpower. Leveraging automation for continuous monitoring of configurations, access controls, and network flows ensures ongoing adherence to compliance standards. Automated tools can flag deviations from policies in real-time, identify misconfigurations before they become vulnerabilities, and provide instant insights into your compliance posture. Think of it as having an always-on, hyper-vigilant auditor embedded directly within your cloud infrastructure. It frees up your security teams to focus on more strategic initiatives, rather than endless manual checks. Prove it: Maintain comprehensive audit trails Compliance isn't just about being compliant; it's about proving you're compliant. When an auditor comes knocking – and they will – you need to provide clear, irrefutable, and easily accessible evidence of your compliance posture. This means maintaining comprehensive, immutable audit trails . Ensure that all security events, configuration changes, network access attempts, and policy modifications are meticulously logged and retained. These logs serve as your digital paper trail, demonstrating due diligence and adherence to regulatory requirements. The ability to quickly retrieve specific audit data is critical during assessments, turning what could be a stressful scramble into a smooth, evidence-based conversation. The dynamic duo: Regular review and adaptation Cloud environments are not static. Regulations evolve, new services emerge, and your own business needs change. Therefore, compliance in the cloud is never a "set it and forget it" task. It requires a dynamic approach: regular review and adaptation . Implement a robust process for periodically reviewing your compliance controls. Are they still relevant? Are there new regulations or updates you need to account for? Are your existing controls still effective against emerging threats? Adapt your policies and controls as needed to ensure continuous alignment with both external regulatory demands and your internal security posture. This proactive stance keeps you ahead of potential issues rather than constantly playing catch-up. Simplify Your Journey with the Right Tools Ultimately, staying compliant in the cloud boils down to three core pillars: clear visibility into your cloud environment, consistent and automated policy enforcement, and the demonstrable ability to prove adherence. This is where specialized tools can be invaluable. Solutions like AlgoSec Cloud Enterprise can truly be your trusted co-pilot in this intricate journey. It's designed to help you discover all your cloud assets across multiple providers, proactively identify compliance risks and misconfigurations, and automate policy enforcement. By providing a unified view and control plane, it gives you the confidence that your multi-cloud environment not only meets but also continuously maintains the strictest regulatory requirements. Don't let the complexities of cloud compliance slow your innovation or introduce unnecessary risk. Embrace strategic approaches, leverage automation, and choose the right partners to keep those clouds compliant and your business secure.

Tags Share this article 7/15/14 Published Insecure Service Protocols and Ports Okay, we all have them… they’re everyone’s dirty little network security secrets that we try not to talk about. They’re the protocols that we don’t mention in a security audit or to other people in the industry for fear that we’ll be publicly embarrassed. Yes, I’m talking about cleartext protocols which are running rampant across many networks. They’re in place because they work, and they work well, so no one has had a reason to upgrade them. Why upgrade something if it’s working right? Wrong. These protocols need to go the way of records, 8-tracks and cassettes (many of these protocols were fittingly developed during the same era). You’re putting your business and data at serious risk by running these insecure protocols. There are many insecure protocols that are exposing your data in cleartext, but let’s focus on the three most widely used ones: FTP, Telnet and SNMP. FTP (File Transfer Protocol) This is by far the most popular of the insecure protocols in use today. It’s the king of all cleartext protocols and one that needs to be smitten from your network before it’s too late. The problem with FTP is that all authentication is done in cleartext which leaves little room for the security of your data. To put things into perspective, FTP was first released in 1971, almost 45 years ago. In 1971 the price of gas was 40 cents a gallon, Disneyland had just opened and a company called FedEx was established. People, this was a long time ago. You need to migrate from FTP and start using an updated and more secure method for file transfers, such as HTTPS, SFTP or FTPS. These three protocols use encryption on the wire and during authentication to secure the transfer of files and login. Telnet If FTP is the king of all insecure file transfer protocols then telnet is supreme ruler of all cleartext network terminal protocols. Just like FTP, telnet was one of the first protocols that allowed you to remotely administer equipment. It became the defacto standard until it was discovered that it passes authentication using cleartext. At this point you need to hunt down all equipment that is still running telnet and replace it with SSH, which uses encryption to protect authentication and data transfer. This shouldn’t be a huge change unless your gear cannot support SSH. Many appliances or networking gear running telnet will either need the service enabled or the OS upgraded. If both of these options are not appropriate, you need to get new equipment, case closed. I know money is an issue at times, but if you’re running a 45 year old protocol on your network with the inability to update it, you need to rethink your priorities. The last thing you want is an attacker gaining control of your network via telnet. Its game over at this point. SNMP (Simple Network Management Protocol) This is one of those sneaky protocols that you don’t think is going to rear its ugly head and bite you, but it can! escortdate escorts . There are multiple versions of SNMP, and you need to be particularly careful with versions 1 and 2. For those not familiar with SNMP, it’s a protocol that enables the management and monitoring of remote systems. Once again, the strings can be sent via cleartext, and if you have access to these credentials you can connect to the system and start gaining a foothold on the network, including managing, applying new configurations or gaining in-depth monitoring details of the network. In short, it a great help for attackers if they can get hold of these credentials. Luckily version 3.0 of SNMP has enhanced security that protects you from these types of attacks. So you must review your network and make sure that SNMP v1 and v2 are not being used. These are just three of the more popular but insecure protocols that are still in heavy use across many networks today. By performing an audit of your firewalls and systems to identify these protocols, preferably using an automated tool such as AlgoSec Firewall Analyzer , you should be able to pretty quickly create a list of these protocols in use across your network. It’s also important to proactively analyze every change to your firewall policy (again preferably with an automated tool for security change management ) to make sure no one introduces insecure protocol access without proper visibility and approval. Finally, don’t feel bad telling a vendor or client that you won’t send data using these protocols. If they’re making you use them, there’s a good chance that there are other security issues going on in their network that you should be concerned about. It’s time to get rid of these protocols. They’ve had their usefulness, but the time has come for them to be sunset for good.

Risk Management and Vulnerabilities How to optimize the security policy management lifecycle 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 8/9/23 Published Information security is vital to business continuity. Organizations trust their IT teams to enable innovation and business transformation but need them to safeguard digital assets in the process. This leads some leaders to feel that their information security policies are standing in the way of innovation and business agility. Instead of rolling new a new enterprise application and provisioning it for full connectivity from the start, security teams demand weeks or months of time to secure those systems before they’re ready. But this doesn’t mean that cybersecurity is a bottleneck to business agility. The need for speedier deployment doesn’t automatically translate to increased risk. Organizations that manage application connectivity and network security policies using a structured lifecycle approach can improve security without compromising deployment speed. Many challenges stand between organizations and their application and network connectivity goals. Understanding each stage of the lifecycle approach to security policy change management is key to overcoming these obstacles. Challenges to optimizing security policy management ` Complex enterprise infrastructure and compliance requirements A medium-sizded enterprise may have hundreds of servers, systems, and security solutions like firewalls in place. These may be spread across several different cloud providers, with additional inputs from SaaS vendors and other third-party partners. Add in strict regulatory compliance requirements like HIPAA , and the risk management picture gets much more complicated. Even voluntary frameworks like NIST heavily impact an organization’s information security posture, acceptable use policies, and more – without the added risk of non-compliance. Before organizations can optimize their approach to security policy management, they must have visibility and control over an increasingly complex landscape. Without this, making meaningful progress of data classification and retention policies is difficult, if not impossible. Modern workflows involve non-stop change When information technology teams deploy or modify an application, it’s in response to an identified business need. When those deployments get delayed, there is a real business impact. IT departments now need to implement security measures earlier, faster, and more comprehensively than they used to. They must conduct risk assessments and security training processes within ever-smaller timeframes, or risk exposing the organization to vulnerabilities and security breaches . Strong security policies need thousands of custom rules There is no one-size-fits-all solution for managing access control and data protection at the application level. Different organizations have different security postures and security risk profiles. Compliance requirements can change, leading to new security requirements that demand implementation. Enterprise organizations that handle sensitive data and adhere to strict compliance rules must severely restrict access to information systems. It’s not easy to achieve PCI DSS compliance or adhere to GDPR security standards solely through automation – at least, not without a dedicated change management platform like AlgoSec . Effectively managing an enormous volume of custom security rules and authentication policies requires access to scalable security resources under a centralized, well-managed security program. Organizations must ensure their security teams are equipped to enforce data security policies successfully. Inter-department communication needs improvement Application deliver managers, network architects, security professionals, and compliance managers must all contribute to the delivery of new application projects. Achieving clear channels of communication between these different groups is no easy task. In most enterprise environments, these teams speak different technical languages. They draw their data from internally siloed sources, and rarely share comprehensive documentation with one another. In many cases, one or more of these groups are only brought in after everyone else has had their say, which significantly limits the amount of influence they can have. The lifecycle approach to managing IT security policies can help establish a standardized set of security controls that everyone follows. However, it also requires better communication and security awareness from stakeholders throughout the organization. The policy management lifecycle addresses these challenges in five stages ` Without a clear security policy management lifecycle in place, most enterprises end up managing security changes on an ad hoc basis. This puts them at a disadvantage, especially when security resources are stretched thin on incident response and disaster recovery initiatives. Instead of adopting a reactive approach that delays application releases and reduces productivity, organizations can leverage the lifecycle approach to security policy management to address vulnerabilities early in the application development lifecycle. This leaves additional resources available for responding to security incidents, managing security threats, and proactively preventing data breaches. Discover and visualize application connectivity The first stage of the security policy management lifecycle revolves around mapping how your apps connect to each other and to your network setup. The more details can include in this map, the better prepared your IT team will be for handling the challenges of policy management. Performing this discovery process manually can cost enterprise-level security teams a great deal of time and accuracy. There may be thousands of devices on the network, with a complex web of connections between them. Any errors that enter the framework at this stage will be amplified through the later stages – it’s important to get things right at this stage. Automated tools help IT staff improve the speed and accuracy of the discovery and visualization stage. This helps everyone – technical and nontechnical staff included – to understand what apps need to connect and work together properly. Automated tools help translate these needs into language that the rest of the organization can understand, reducing the risk of misconfiguration down the line. Plan and assess security policy changes Once you have a good understanding of how your apps connect with each other and your network setup, you can plan changes more effectively. You want to make sure these changes will allow the organization’s apps to connect with one another and work together without increasing security risks. It’s important to adopt a vulnerability-oriented perspective at this stage. You don’t want to accidentally introduce weak spots that hackers can exploit, or establish policies that are too complex for your organization’s employees to follow. This process usually involves translating application connectivity requests into network operations terms. Your IT team will have to check if the proposed changes are necessary, and predict what the results of implementing those changes might be. This is especially important for cloud-based apps that may change quickly and unpredictably. At the same time, security teams must evaluate the risks and determine whether the changes are compliant with security policy. Automating these tasks as part of a regular cycle ensures the data is always relevant and saves valuable time. Migrate and deploy changes efficiently The process of deploying new security rules is complex, time-consuming, and prone to error . It often stretches the capabilities of security teams that already have a wide range of operational security issues to address at any given time. In between managing incident response and regulatory compliance, they must now also manually update thousands of security rules over a fleet of complex network assets. This process gets a little bit easier when guided by a comprehensive security policy change management framework. But most organizations don’t unlock the true value of the security policy management lifecycle until they adopt automation. Automated security policy management platforms enable organizations to design rule changes intelligently, migrate rules automatically, and push new policies to firewalls through a zero-touch interface. They can even validate whether the intended changes updated correctly. This final step is especially important. Without it, security teams must manually verify whether their new policies successfully address the vulnerabilities the way they’re supposed to. This doesn’t always happen, leaving security teams with a false sense of security. Maintain configurations using templates Most firewalls accumulate thousands of rules as security teams update them against new threats. Many of these rules become outdated and obsolete over time, but remain in place nonetheless. This adds a great deal of complexity to small-scale tasks like change management, troubleshooting issues, and compliance auditing. It can also impact the performance of firewall hardware , which decreases the overall lifespan of expensive physical equipment. Configuration changes and maintenance should include processes for identifying and eliminating rules that are redundant, misconfigured, or obsolete. The cleaner and better-documented the organization’s rulesets are, the easier subsequent configuration changes will be. Rule templates provide a simple solution to this problem. Organizations that create and maintain comprehensive templates for their current firewall rulesets can easily modify, update, and change those rules without having to painstakingly review and update individual devices manually. Decommission obsolete applications completely Every business application will eventually reach the end of its lifecycle. However, many organizations keep decommissioned security policies in place for one of two reasons: Oversight that stems from unstandardized or poorly documented processes, or; Fear that removing policies will negatively impact other, active applications. As these obsolete security policies pile up, they force the organization to spend more time and resources updating their firewall rulesets. This adds bloat to firewall security processes, and increases the risk of misconfigurations that can lead to cyber attacks. A standardized, lifecycle-centric approach to security policy management makes space for the structured decommissioning of obsolete applications and the rules that apply to them. This improves change management and ensures the organization’s security posture is optimally suited for later changes. At the same time, it provides comprehensive visibility that reduces oversight risks and gives security teams fewer unknowns to fear when decommissioning obsolete applications. Many organizations believe that Security stands in the way of the business – particularly when it comes to changing or provisioning connectivity for applications. It can take weeks, or even months to ensure that all the servers, devices, and network segments that support the application can communicate with each other while blocking access to hackers and unauthorized users. It’s a complex and intricate process. This is because, for every single application update or change, Networking and Security teams need to understand how it will affect the information flows between the various firewalls and servers the application relies on, and then change connectivity rules and security policies to ensure that only legitimate traffic is allowed, without creating security gaps or compliance violations. As a result, many enterprises manage security changes on an ad-hoc basis: they move quickly to address the immediate needs of high-profile applications or to resolve critical threats, but have little time left over to maintain network maps, document security policies, or analyze the impact of rule changes on applications. This reactive approach delays application releases, can cause outages and lost productivity, increases the risk of security breaches and puts the brakes on business agility. But it doesn’t have to be this way. Nor is it necessary for businesses to accept greater security risk to satisfy the demand for speed. Accelerating agility without sacrificing security The solution is to manage application connectivity and network security policies through a structured lifecycle methodology, which ensures that the right security policy management activities are performed in the right order, through an automated, repeatable process. This dramatically speeds up application connectivity provisioning and improves business agility, without sacrificing security and compliance. So, what is the network security policy management lifecycle, and how should network and security teams implement a lifecycle approach in their organizations? Discover and visualize The first stage involves creating an accurate, real-time map of application connectivity and the network topology across the entire organization, including on-premise, cloud, and software-defined environments. Without this information, IT staff are essentially working blind, and will inevitably make mistakes and encounter problems down the line. Security policy management solutions can automate the application connectivity discovery, mapping, and documentation processes across the thousands of devices on networks – a task that is enormously time-consuming and labor-intensive if done manually. In addition, the mapping process can help business and technical groups develop a shared understanding of application connectivity requirements. Plan and assess Once there is a clear picture of application connectivity and the network infrastructure, you can start to plan changes more effectively – ensure that proposed changes will provide the required connectivity, while minimizing the risks of introducing vulnerabilities, causing application outages, or compliance violations. Typically, it involves translating application connectivity requests into networking terminology, analyzing the network topology to determine if the changes are really needed, conducting an impact analysis of proposed rule changes (particularly valuable with unpredictable cloud-based applications), performing a risk and compliance assessment, and assessing inputs from vulnerabilities scanners and SIEM solutions. Automating these activities as part of a structured lifecycle keeps data up-to-date, saves time, and ensures that these critical steps are not omitted – helping avoid configuration errors and outages. Functions Of An Automatic Pool Cleaner An automatic pool cleaner is very useful for people who have a bad back and find it hard to manually operate the pool cleaner throughout the pool area. This type of pool cleaner can move along the various areas of a pool automatically. Its main function is to suck up dirt and other debris in the pool. It functions as a vacuum. Automatic pool cleaners may also come in different types and styles. These include automatic pressure-driven cleaners, automatic suction side-drive cleaners, and robotic pool cleaners. Migrate and deploy Deploying connectivity and security rules can be a labor-intensive and error-prone process. Security policy management solutions automate the critical tasks involved, including designing rule changes intelligently, automatically migrating rules, and pushing policies to firewalls and other security devices – all with zero-touch if no problems or exceptions are detected. Crucially, the solution can also validate that the intended changes have been implemented correctly. This last step is often neglected, creating the false impression that application connectivity has been provided, or that vulnerabilities have been removed, when in fact there are time bombs ticking in the network. Maintain Most firewalls accumulate thousands of rules which become outdated or obsolete over the years. Bloated rulesets not only add complexity to daily tasks such as change management, troubleshooting and auditing, but they can also impact the performance of firewall appliances, resulting in decreased hardware lifespan and increased TCO. Cleaning up and optimizing security policies on an ongoing basis can prevent these problems. This includes identifying and eliminating or consolidating redundant and conflicting rules; tightening overly permissive rules; reordering rules; and recertifying expired ones. A clean, well-documented set of security rules helps to prevent business application outages, compliance violations, and security gaps and reduces management time and effort. Decommission Every business application eventually reaches the end of its life: but when they are decommissioned, its security policies are often left in place, either by oversight or from fear that removing policies could negatively affect active business applications. These obsolete or redundant security policies increase the enterprise’s attack surface and add bloat to the firewall ruleset. The lifecycle approach reduces these risks. It provides a structured and automated process for identifying and safely removing redundant rules as soon as applications are decommissioned while verifying that their removal will not impact active applications or create compliance violations. We recently published a white paper that explains the five stages of the security policy management lifecycle in detail. It’s a great primer for any organization looking to move away from a reactive, fire-fighting response to security challenges, to an approach that addresses the challenges of balancing security and risk with business agility.

Tags Share this article 4/13/22 Published Prof. Avishai Wool, AlgoSec co-founder and CTO, stresses the importance of getting the often-overlooked function of managing network objects right, particularly in hybrid or multi-vendor environments Using network traffic filtering solutions from multiple vendors makes network object management much more challenging. Each vendor has its own management platform, which often forces network security admins to define objects multiple times, resulting in a counter effect. First and foremost, this can be an inefficient use of valuable resources from a workload bottlenecking perspective. Secondly, it creates a lack of naming consistency and introduces a myriad of unexpected errors, leading to security flaws and connectivity problems. This can be particularly applicable when a new change request is made. With these unique challenges at play, it begs the question: Are businesses doing enough to ensure their network objects are synchronized in both legacy and greenfield environments? What is network object management? At its most basic, the management of network objects refers to how we name and define “objects” within a network. These objects can be servers, IP addresses, or groups of simpler objects. Since these objects are subsequently used in network security policies, it is imperative to simultaneously apply a given rule to an object or object group. On its own, that’s a relatively straightforward method of organizing the security policy. But over time, as organizations reach scale, they often end up with large quantities of network objects in the tens of thousands, which typically lead to critical mistakes. Hybrid or multi-vendor networks Let’s take name duplication as an example. Duplication on its own is bad enough due to the wasted resource, but what’s worse is when two copies of the same name have two distinctly different definitions. Let’s say we have a group of database servers in Environment X containing three IP addresses. This group is allocated a name, say “DBs”. That name is then used to define a group of database servers in Environment Y containing only two IP addresses because someone forgot to add in the third. In this example, the security policy rule using the name DBs would look absolutely fine to even a well-trained eye, because the names and definitions it contained would seem identical. But the problem lies in what appears below the surface: one of these groups would only apply to two IP addresses rather than three. As in this case, minor discrepancies are commonplace and can quickly spiral into more significant security issues if not dealt with in the utmost time-sensitive manner. It’s important to remember that accuracy is the name in this game. If a business is 100% accurate in the way it handles network object management, then it has the potential to be 100% efficient. The Bottom Line The security and efficiency of hybrid multi-vendor environments depend on an organization’s digital hygiene and network housekeeping. The naming and management of network objects aren’t particularly glamorous tasks. Having said that, everything from compliance and automation to security and scalability will be far more seamless and risk averse if taken care of correctly.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/25/23 Published Fortified network security requires getting a variety of systems and platforms to work together. Security teams need to scan for potential threats, look for new vulnerabilities in the network, and install software patches in order to keep these different parts working smoothly. While small organizations with dedicated cybersecurity teams may process these tasks manually at first, growing audit demands will quickly outpace their capabilities. Growing organizations and enterprises rely on automation to improve IT security auditing and make sure their tech stack is optimized to keep hackers out. Network Security Audit Tools Explained Network Security Audit Tools provide at-a-glance visibility into network security operations and infrastructure. They scan network security tools throughout the environment and alert administrators of situations that require their attention. These situations can be anything from emerging threats, newly discovered vulnerabilities, or newly released patches for important applications. Your network security audit tools provide a centralized solution for managing the effectiveness of your entire security tech stack – including cloud-based software solutions and on-premises tools alike. With such a wide set of responsibilities, it should come as no surprise that many audit tools differ widely from one another. Some are designed for easy patch management while others may focus on intrusion detection or sensitive data exfiltration. Major platforms and operating systems may even include their own built-in audit tools. Microsoft Windows has an audit tool that focuses exclusively on Active Directory. However, enterprise security teams don’t want to clutter their processes with overlapping tools and interfaces – they want to consolidate their auditing tools onto platforms that allow for easy management and oversight. Types of Network Security Audit Tools Firewall Auditing Tools Firewall security rules provide clear instructions to firewalls on what kind of traffic is permitted to pass through. Firewalls can only inspect connections they are configured to detect . These rules are not static , however. Since the cybersecurity threat landscape is constantly changing, firewall administrators must regularly update their policies to accommodate new types of threats. At the same time, threat actors who infiltrate firewall management solutions can gain a critical advantage over their targets. They can change the organization’s security policies to ignore whatever malicious traffic they are planning on using to compromise the network. If these changes go unnoticed, even the best security technologies won’t be able to detect or respond to the threat. Security teams must regularly evaluate their firewall security policies to make sure they are optimized for the organization’s current risk profile. This means assessing the organization’s firewall rules and determining whether it is meeting its security needs. The auditing process may reveal overlapping rules, unexpected configuration changes , or other issues. Vulnerability Scanners Vulnerability scanners are automated tools that create an inventory of all IT assets in the organization and scan those assets for weak points that attackers may exploit. They also gather operational details of those assets and use that information to create a comprehensive map of the network and its security risk profile. Even a small organization may have thousands of assets. Hardware desktop workstations, laptop computers, servers, physical firewalls, and printers all require vulnerability scanning. Software assets like applications , containers, virtual machines, and host-based firewalls must also be scanned. Large enterprises need scanning solutions capable of handling enormous workloads rapidly. These tools provide security teams with three key pieces of information: Weaknesses that hackers know how to exploit . Vulnerability scanners work based on known threats that attackers have exploited in the past. They show security teams exactly where hackers could strike, and how. The degree of risk associated with each weakness . Since scanners have comprehensive information about every asset in the network, they can also predict the damage that might stem from an attack. This allows security teams to focus on high-priority risks first. Recommendations on how to address each weakness . The best vulnerability scanners provide detailed reports with in-depth information on how to mitigate potential threats. This gives security personnel step-by-step information on how to improve the organization’s security posture. Penetration Testing Tools Penetration testing allows organizations to find out how resilient their assets and processes might be in the face of an active cyberattack. Penetration testers use the same tools and techniques hackers use to exploit their victims, showing organizations whether their security policies actually work. Traditionally, penetration testing is carried out by two teams of cybersecurity professionals. The “red team” attempts to infiltrate the network and access sensitive data while the “blue team” takes on defense. Cybersecurity professionals should know how to use the penetration testing tools employed by hackers and red team operatives. Most of these tools have legitimate uses and are a fixture of many IT professionals’ toolkits. Some examples include: Port scanners . These identify open ports on a particular system. This can help users identify the operating system and find out what applications are running on the network. Vulnerability scanners . These search for known vulnerabilities in applications, operating systems, and servers. Vulnerability reports help penetration testers identify the most reliable entry point into a protected network. Network analyzers . Also called network sniffers, these tools monitor the data traveling through the network. They can provide penetration testers with information about who is communicating over the network, and what protocols and ports they are using. These tools help security professionals run security audits by providing in-depth data on how specific attack attempts might play out. Additional tools like web proxies and password crackers can also play a role in penetration testing, providing insight into the organization’s resilience against known threats.

Steps to Conduct a Network Security Audit Define the Scope : Start by defining the scope of your audit. You’ll need to determine which parts of your network and systems will be audited. Consider the goals and objectives of the audit, such as identifying vulnerabilities, ensuring compliance, or assessing overall security posture. Gather Information : Collect all relevant information about your network, including network diagrams, asset inventories, and existing security policies and procedures. This information will serve as a baseline for your audit. The more comprehensive this information is, the more accurate your audit results can be. Identify Assets : List all the assets on your network, including servers, routers, switches, firewalls, and endpoints. Ensure that you have a complete inventory of all devices and their configurations. If this information is not accurate, the audit may overlook important gaps in your security posture. Assess Vulnerabilities : Use network vulnerability scanning tools to identify vulnerabilities in your network. Vulnerability scanners like Nessus or OpenVAS can help pinpoint weaknesses in software, configurations, or missing patches. This process may take a long time if it’s not supported by automation. Penetration Testing : Conduct penetration testing to simulate cyberattacks and assess how well your network defenses hold up. Penetration testing tools like Metasploit or Burp Suite can help identify potential security gaps. Automation can help here, too – but the best penetration testing services emulate the way hackers work in the real world. Review Policies and Procedures : Evaluate the results of your vulnerability and penetration testing initiatives. Review your existing security policies and procedures to ensure they align with best practices and compliance requirements. Make necessary updates or improvements based on audit findings. Log Analysis : Analyze network logs to detect any suspicious or unauthorized activities. Log analysis tools like Splunk or ELK Stack can help by automating the process of converting log data into meaningful insights. Organizations equipped with SIEM platforms can analyze logs in near real-time and continuously monitor their networks for signs of unauthorized behavior. Review Access Controls : Ensure the organization’s access control policies are optimal. Review user permissions and authentication methods to prevent unauthorized access to critical resources. Look for policies and rules that drag down production by locking legitimate users out of files and folders they need to access. Firewall and Router Configuration Review: Examine firewall and router configurations to verify that they are correctly implemented and that access rules are up to date. Ensure that only necessary ports are open, and that the organization’s firewalls are configured to protect those ports. Prevent hackers from using port scanners or other tools to conduct reconnaissance. Patch Management : Check for missing patches and updates on all network devices and systems. Regularly update and patch software to address known vulnerabilities. Review recently patched systems to make sure they are still compatible with the tools and technologies they integrate with. Incident Response Plan : Review and update your incident response plan. Ensure the organization is prepared to respond effectively to security incidents, and can rely on up-to-date playbooks in the event of a breach. Compare incident response plans with the latest vulnerability scanning data and emerging threat intelligence information. Documentation and Reporting: Document all audit findings, vulnerabilities, and recommended remediation steps. Generate data visualizations that guide executives and other stakeholders through the security audit process and explain its results. Create a comprehensive report that includes an executive summary, technical details, and prioritized action items. Remediation : Implement the necessary changes and remediation measures to address the identified vulnerabilities and weaknesses. Deploy limited security resources effectively, prioritizing fixes based on their severity. Avoid unnecessary downtime when reconfiguring security tools and mitigating risk. Follow-Up Audits: Schedule regular follow-up audits to ensure that the identified vulnerabilities have been addressed and that security measures are continuously improved. Compare the performance metric data gathered through multiple audits and look for patterns emerging over time. Training and Awareness: Provide training and awareness programs for employees to enhance their understanding of security best practices and their role in maintaining network security. Keep employees well-informed about the latest threats and vulnerabilities they must look out for. FAQs What are some general best practices for network security auditing? Network security audits should take a close look at how the organization handles network configuration management over time. Instead of focusing only on how the organization’s current security controls are performing, analysts should look for patterns that predict how the organization will perform when new threats emerge in the near future. This might mean implementing real-time monitoring and measuring how long it takes for obsolete rules to get replaced. What is the ideal frequency for conducting network security audits? Network security audits should be conducted at least annually, with more frequent audits recommended for organizations with high-security requirements. Automated policy management platforms like AlgoSec can help organizations audit their security controls continuously. Are network security audit tools effective against zero-day vulnerabilities? Network security audit tools may not detect zero-day vulnerabilities immediately. However, they can still contribute by identifying other weaknesses that could be exploited in tandem with a zero-day vulnerability. They also provide information on how long it takes the organization to recognize new vulnerabilities once they are discovered. What should I look for when choosing a network security audit tool for my organization? Consider factors like the tool’s compatibility with your network infrastructure, reporting capabilities, support and updates, and its track record in identifying vulnerabilities relevant to your industry. Large enterprises highly value scalable tools that support automation. Can network security audit tools help with regulatory compliance? Yes, many audit tools offer compliance reporting features, helping organizations adhere to various industry and government regulations. Without an automated network security audit tool in place, many organizations would be unable to consistently demonstrate compliance. How long does it take to conduct a typical network security audit? The duration of an audit varies depending on the size and complexity of the network. A thorough audit can take anywhere from a few days to several weeks. Continuous auditing eliminates the need to disrupt daily operations when conducting audits, allowing security teams to constantly improve performance. What are the most common mistakes organizations make during network security audits? Common mistakes include neglecting to update audit tools regularly, failing to prioritize identified vulnerabilities, and not involving key stakeholders in the audit process. Overlooking critical assets like third-party user accounts can also lead to inaccurate audit results. What are some important capabilities needed for a Cloud-Based Security Audit? Cloud-based security audits can quickly generate valuable results by scanning the organization’s cloud-hosted IT assets for vulnerabilities and compliance violations. However, cloud-based audit software must be able to recognize and integrate third-party SaaS vendors and their infrastructure. Third-party tools and platforms can present serious security risks, and must be carefully inspected during the audit process. What is the role of Managed Service Providers (MSPs) in Network Security Auditing? MSPs can use audits to demonstrate the value of their services and show customers where improvement is needed. Since this improvement often involves the customer drawing additional resources from the MSP, comprehensive audits can improve the profitability of managed service contracts and deepen the connection between MSPs and their customers.

Tags Share this article 8/9/23 Published If your firewall shows a notification that it has detected a new network, it means it is doing one of its fundamental jobs properly. But good network security does not stop with just detecting a new network. You will have to analyze the network location, ensure it is authorized to connect with your network, automate this process, and ensure full-on monitoring so that none of the intrusive attempts ever go unnoticed. A good amount of all these tasks can be made more efficient, accurate, and automated with the help of strong network security solutions. What should you do if your firewall has detected an unrecognized network? 1. Analyze the incoming network request If the process is not automated, you might have to check for the incoming network request’s trustworthiness manually. You can check the security certificates associated with the request, check its source, validate with the right information whether this source can be trusted, and then decide whether to allow access. The best way to deal with any new network detection is to automate the authorization by using a strong network security policy that outlines what sources can be trusted, what cannot be trusted, and which decisions require further approval. 2. Analyze your network for any impact In case of an untrusted new network detection and possible intrusion, you should be able to check the impact or effect it has had on your current assets. You should analyze the entire system for performance, feature validation, and asset availability. A quick way to do this would be to use any network visualization product, such as Firewall Analyzer . This tool can also assess how your overall home network will be impacted by any possible security policy 3. Reassess your security policies and improve them In the event of any security incident, you will have to isolate your network, mitigate any impact caused by the intrusion and reset the system to a healthy state. And most importantly, you will have to investigate the incident, figure out the root cause, and fix it. This would require updating your security policies, risk management, and local network security settings. Following up on any security incident is highly recommended so that no unauthorized intrusion attempts go unnoticed and are handled appropriately. And like any other seemingly enormous task, this can be automated too. Check out firewall change management tools to help you implement continuous improvement within your network security management, contributing to network protection. How to setup strong firewall protection Here are some security measures and troubleshooting tips you need to employ to strengthen your Microsoft firewall management and network security. 1. Establish a strong network security policy management To implement a strong network security management framework, you must design the security policies, systems, and solutions as per your operating system. A network security policy framework can help you guide and streamline the security design and guide you with the enforcement of the same. As with any process, policy management should also be a continuously evolving framework and must be managed well to facilitate all the relevant tasks. Use intelligent systems like Algosec’s Algobot to help your firewall admins to carry out their tasks efficiently. And if you are looking to automate the security policy management tasks, you can also check out Fireflow . It helps you automate the security policy change process across the many phases of policy management, from planning to implementation and validation. 2. Visualize the network data Network monitoring is critical to enabling t strong firewall While AI-based alerting and monitoring systems could greatly help automate intrusion detection and notification, certain tasks require human supervision and deep analysis of the network logs. This way, you can not only analyze the network for any intrusion attempts (whether it be through malware sent through a web browser, file sharing, router, ethernet network adapter, or wi-fi) but also get to have a good understanding of your traffic and business trends. Appviz Firewall Analyzer from Algosec is a helpful tool for achieving this functionality. 3. Optimize your firewall configuration Firewall configurations include a broad range of activities that range from designing your firewall solution and choosing the right software/hardware to setting up the firewall rules and management processes. Set these configurations early on with all necessary considerations regarding your environment and applications. This process should also include the overall policy configurations and security rules that define the change process, firewall administration, monitoring, and management operations. Read this resourceful guide to learn more about firewall configuration, its challenges, and guidance on implementation. 4. Ensure cloud compliance Compliance and security go hand in hand in protecting your assets and boosting the overall goodwill and trust associated with your brand. Cloud compliance frameworks provide guidelines and cover most of the pain points of managing cloud security. Staying compliant with these guidelines means that your security is up to date and can be considered on par with the high standards set by these frameworks. 5. Micro-segmentation Micro-segmentation is a domain network security technique that helps you implement flexible security measures for individually segmented data center parts. It is most helpful with protecting your virtual machine implementations as it allows you to deploy specific security measures crafted to fit each virtual machine’s requirements. With security deployed on segmented workloads, your network becomes more resilient to attacks. 6. Perform regular firewall audits To ensure continuous compliance, you must conduct regular audit checks on the status of your firewall settings, policies, and implementations. Gather all the related documents and key information, review your current processes, firewall mechanisms, perform penetration tests, assess the security measures, and optimize as required. Perform a complete risk assessment on your Windows server and fix any issues that might be discovered as part of the audit process. Tips and best practices for enhanced network security 1. Firewall for native cloud applications Make use of cloud-first prioritized firewall solutions to protect your native cloud applications. You need comprehensive visibility on all your cloud assets, ensuring advanced threat detection and protection. This requires a whole set of tools and security applications working together to provide a centralized security system. You will also have to ensure data compliance at all levels as well. You can try to employ native cloud solutions such as the extensive tools provided by Algosec. 2. Use centralized solutions Make use of centralized solutions to manage hybrid and multi-cloud applications so that you have all the important information accessible from a single platform. AlgoSec Cloud from Algosec is an amazing solution to achieve centralized visibility across hybrid and multi-cloud accounts and assets. 3. Follow the best security practices and guidelines Look into the best security practices and guidelines put forth by your cloud vendor and follow them to get the best out of the collective knowledge. You can also use vendor-specific firewall management solutions to help you deal with issues related to specific cloud accounts you might be using. Additionally, having an antivirus like Windows Defender and using a VPN also helps. A good practice to follow in case of uncertainty is to block by default. Any new network or source must be blocked unless specifically permitted by the user. Regarding access privileges, you can follow the principle of least privilege, where users are only granted as many privileges as would be required for their specific roles and responsibilities. Use audit tools for regular auditing and keep improving on any vulnerabilities your firewall may have. To increase the performance of your firewall applications, you can look into how you have set up your firewall rules and optimize them for better performance. Here are some more best practices you can follow when setting up your firewall rules: Document all your rules and firewall configurations across all the devices. Make sure to document every new rule created and keep your documentation up to date. This can help security admins review the rules and optimize them as and when necessary. As mentioned earlier, follow a zero trust policy where you block traffic by default and permit network access only on a need basis. Monitor your firewall logs even when there is no particular security incident to investigate. Regular monitoring and analysis will give you a better understanding of your network traffic and can help you identify suspicious activities early on. Group the firewall rules to boost performance and avoid complications and loopholes. You can hire expert security administrators and security solutions such as Algosec to help review your firewall rules and keep them updated. Firewall management FAQs What can a firewall do? A Windows firewall can be interpreted as similar to a literal wall. It blocks unwanted access to your system and lets you decide whether or not to allow any new network connection or access request. Similar to how a fort works, you only give access to access requests that you trust and block the rest. It is the first defensive setup you can set up for your network security. You can set a list of trusted sources, and the requests from these sources will be given automated access. The rest of the access requests from any other source, be it a third-party network, mobile devices, internet connection, or any other endpoint, can be blocked by your firewall. You can set up firewall rules that dictate which type of requests and sources can be trusted. A firewall can be implemented by using multiple methods. It can be a cloud app, hardware, software, virtualizations, an access-restricted private cloud, and more. A typical firewall ruleset consists of the following specifications: Source address Source port Destination address Destination port Information on whether to block or permit the traffic to the respective address and port criteria. A firewall can be implemented by using multiple methods. It can be a cloud app, hardware, software, virtualizations, an access-restricted private cloud, and more. How does a firewall protect businesses from cyberthreats? The obvious main use of the firewall is to restrict all kinds of unauthorized access, thus protecting your systems from cyberattacks. But it also has several other benefits, such as: Providing data privacy so your work network traffic is guarded from outside public networks. Restricting content access to your private network For instance, educational institutions can block inappropriate sites for their students while in class. Blocking unwanted traffic from ads, spam, and gaming sites. Ensuring data confidentiality and keeping you compliant with security standards. Monitoring all your incoming traffic, helping you analyze your network profile, and helping you gain insights into trending user behavior. Filtering out unwanted traffic and restricting access to certain websites. Providing secure remote access through VPNs and similar remote access mechanisms. What are the most common types of firewalls? Based on the way data is filtered through a firewall, it can be broadly classified into one of the following types: Packet filtering Stateful inspection firewalls Circuit-level gateway firewalls Proxy firewalls Next-generation firewalls (NGFWs) Threat focused NGFWs Virtual firewalls Cloud-native firewalls Schedule a demo Related Articles 2025 in review: What innovations and milestones defined AlgoSec’s transformative year in 2025?

Tags Share this article 12/23/20 Published The aim of this post is to provide a very high-level illustration of the DNS Tunneling method used in the SolarWinds supply chain attack . An Attacker compromises SolarWinds company and trojanizes a DLL that belongs to its software. Some of the customers receive the malicious DLL as an update for the SolarWinds Orion software. “Corporation XYZ” receives the malicious and digitally signed DLL via update. SolarWinds Orion software loads the malicious DLL as a plugin. Once activated, the DLL reads a local domain name “local.corp-xyz.com” (a fictious name). The malware encrypts the local domain name and adds it to a long domain name. The long domain name is queried with a DNS server (can be tapped by a passive DNS sensor). The recursive DNS server is not authorized to resolve avsvmcloud[.]com, so it forwards the request. An attacker-controlled authoritative DNS server resolves the request with a wildcard A record. The Attacker checks the victim’s name, then adds a CNAME record for the victim’s domain name. The new CNAME record resolves the long domain name into an IP of an HTTP-based C2 server. The malicious DLL downloads and executes the 2nd stage malware (TearDrop, Cobalt Strike Beacon). A Threat Researcher accesses the passive DNS (pDNS) records. One of the long domain names from the pDNS records is decrypted back into “local.corp-xyz.com”. The Researcher deducts that the decrypted local domain name belongs to “Corporation XYZ”.

Hybrid Cloud Security Management Six best practices for managing security in the hybrid cloud Omer Ganot 2 min read Omer Ganot 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 8/5/21 Published Omer Ganot, Cloud Security Product Manager at AlgoSec, outlines six key things that businesses should be doing to ensure their security in a hybrid cloud environment Over the course of the past decade, we’ve seen cloud computing vastly transitioning from on-prem to the public cloud. Businesses know the value of the cloud all too well, and most of them are migrating their operations to the cloud as quickly as possible, particularly considering the pandemic and the push to remote working. However, there are major challenges associated with transitioning to the cloud, including the diversity and breadth of network and security controls and a dependency on legacy systems that can be difficult to shake. Public cloud allows organizations for better business continuity, easier scalability and paves the way for DevOps to provision resources and deploy projects quickly. But, what’s the security cost when looking at the full Gpicture of the entire hybrid network? Here I outline the six best practices for managing security in the hybrid cloud: 1. Use next-generation firewalls Did you know that almost half (49%) of businesses report running virtual editions of traditional firewalls in the cloud? It’s becoming increasingly clear that cloud providers’ native security controls are not enough, and that next-gen firewall solutions are needed. While a traditional stateful firewall is designed to monitor incoming and outgoing network traffic, a next-generation firewall (NGFW) includes features such as application awareness and control, integrated breach prevention and active threat intelligence. In other words, while a traditional firewall will allow for layer 1-2 protection, NGFWs allow for protection from levels 3 through 7. 2. Use dynamic objects On-premise security tends to be easier because subnets and IP addresses are typically static. In the cloud, however, workloads are dynamically provisioned and decommissioned, IP addresses change, so traditional firewalls simply cannot keep up. NGFW dynamic objects allow businesses to match a group of workloads using cloud-native categories, and then use these objects in policies to properly enforce traffic and avoid the need to frequently update the policies. 3. Gain 360-degree visibility As with any form of security, visibility is critical. Without that, even the best preventative or remedial strategies will fall flat. Security should be evaluated both in your cloud services and in the path from the internet and data center clients. Having one single view over the entire network estate is invaluable when it comes to hybrid cloud security. AlgoSec’s powerful AutoDiscovery capabilities help you understand the network flows in your organization. You can automatically connect the recognized traffic flows to the business applications that use them and seamlessly manage the network security policy across your entire hybrid estate. 4. Evaluate risk in its entirety Too many businesses are guilty of only focusing on cloud services when it comes to managing security. This leaves them inherently vulnerable on other network paths, such as the ones that run from the internet and data centers towards the services in the cloud. As well as gaining 360-degree visibility over the entire network estate, businesses also need to be sure to actively monitor those areas for risk with equal weighting in terms of priority. 5. Clean up cloud policies regularly The cloud security landscape changes at a faster rate than most businesses can realistically keep up with. For that reason, cloud security groups tend to change with the wind, constantly being adjusted to account for new applications. If a business doesn’t keep on top of its cloud policy ‘housekeeping’, they’ll soon become bloated, difficult to maintain and risky. Keep cloud security groups clean and tidy so they’re accurate, efficient and don’t expose risk. 6. Embrace DevSecOps The cloud might be perfect for DevOps in terms of easy and agile resource and security provisioning using Infrastructure-as-code tools, but the methodology is seldom used for risk analysis and remediation recommendations. Businesses that want to take control of their cloud security should pay close attention to this. Before a new risk is introduced, you should obtain an automatic what-if risk check as part of the code’s pull request, before pushing to production. From visibility and network management right through to risk evaluation and clean-up, staying secure in a hybrid cloud environment might sound like hard work, but by embracing these fundamental practices your organization can start putting together the pieces of its own security puzzle. The AlgoSec Security Management Suite (ASMS) makes it easy to support your cloud migration journey, ensuring that it does not block critical business services and meet compliance requirements.

It will scan the entire cloud environment to detect and prevent misconfiguration errors. This is important because configurations in the cloud happen quickly and just as quickly introduce new threats into the environment. For robust ongoing protection, you need to monitor the environment continuously and automatically. Here’s where CSPM comes in. The best CSPM solutions implement configuration best practices and automatically initiate corrective actions to remove risks, thus improving cloud security, ensuring adherence to compliance policies, and reducing the likelihood of breaches. Additionally, they are agentless, do not require long configuration, and don’t add to your cloud bills by utilizing additional cloud resources. What is Cloud Infrastructure Entitlement Management (CIEM)? In cloud environments, identity goes beyond users and groups. It also plays a vital role in managing all the resources and services that need to access data. All these accesses happen very quickly and constitute a complex web of interactions. It’s crucial to know when and between whom these interactions occur to ensure that only legitimate resources can access or modify data. But as your cloud resources increase, the complexity of entitlements also grows. It’s not easy to keep track of these entitlements or to maintain the security-focused principle of least privilege (PoLP). CIEM tools are specialized identity-centric solutions to manage cloud access risk and govern entitlements in hybrid and multi-cloud environments. With CIEM, you can manage entitlements across all your cloud resources and maintain PoLP to mitigate the risk created by granting excessive permissions to cloud resources. What is a Cloud Workload Protection Platform (CWPP)? CWPP solutions manage cloud applications and workloads. They can reach back into on- prem environments and thus effectively detect and prevent security problems like malware and vulnerabilities across the entire hybrid landscape. CWPP solutions can scale automatically and support your organization as your cloud environment grows or changes. What is a Cloud Native Application Protection Platform (CNAPP)? Each of these solutions are geared towards a specific area of cloud security. CSPM prevents misconfiguration errors, CIEM platforms manage cloud access risks, and CWPP protects your assets and workloads. But what if you want a single solution that can completely manage the security of your cloud environment? Try a Cloud Native Application Protection Platform . CNAPP solutions combine security posture management, workload protection, and entitlement management into one single platform to provide comprehensive, holistic security across multi-cloud environments. Thus, you can protect your entire cloud estate with one solution instead of having to implement and manage multiple point solutions. Another advantage of a CNAPP tool is that it will enable you to “shift left”. Thus, you can not only secure applications in production environments, but also manage the runtime and DevOps aspects of security. For this reason, these platforms are aimed at both security professionals and DevOps practitioners. Conclusion and Next Steps A CNAPP solution is the most comprehensive solution. However, in today’s market there is no one tool that truly covers all the functionalities that CNAPP promises. Therefore, each organization should choose the solution that fits its immediate needs, including taking other considerations into account such as the skill level and the maturity of its cloud adoption. One important thing to remember: Regardless of the solution you choose, make sure it’s agentless. Agentless is important in today’s cloud security because agent-based solutions are hard to manage, expensive, and intrusive. If you’re looking for a modern agentless CSPM with container protection to safeguard your cloud-based application and workload data, then Prevasio might be the best option for you.
