Tags Share this article 9/23/14 Published Virtual Local Area Network (VLAN) Security Issues You’re in no doubt familiar with Virtual Local Area Network (VLAN) technology and its ability to segment traffic within your network. It’s one of those decades-old technologies that businesses have come to rely on to reduce costs, minimize network broadcast domains, and protect certain systems from others. It sounds good on paper but it’s rare to see a VLAN environment that’s truly configured in the right way in order to realize its intended benefits. For example, I’ve seen some networks segmented by physical switches rather than using logical VLANs configured within each managed switch. This means that anyone on the same physical switch/broadcast domain can see every host on that segment. And if they want to see all traffic, it’s often just a matter of using Cain & Abel’s ARP Poison Routing feature . This is not an effective way to manage network devices and there’s no way to prevent inadvertent connections to the wrong segment during network upgrades, troubleshooting, and the like. It becomes a jumbled mess that negates any perceived switching or VLAN benefits. Furthermore, many “virtual” networks allow anyone to hop between segments if they know the IP addressing scheme. For example, say a user is on the 10.10.10.x network and he wants to get onto the production network of 10.0.0.x. No problem… he just points his Web browser, his vulnerability scanner, or whatever to 10.0.0.x and he’s good to go. Worst case, he might have to configure his system with a static IP address on that network, but that’s simple enough to do. This configuration may be considered a “VLAN” that’s managing broadcast traffic but there are no real ACLs, firewall rules, or packet tagging to prevent unauthorized access by internal attackers, malware, and the like. The network is basically flat with no policies and little to no security between any of the network segments and systems. Another thing to remember is that many VLANs are used to partition networks into distinctive segments to separate business units and their unique data sets. Even if the technical aspects of the VLAN configuration are spot on, these environments are often defined at a very high level without involving the actual business unit managers or information owners, therefore there are often security gaps in the segmentation. This means that information specific to a business unit and believed to be isolated is often anything but – it may well be scattered across numerous other VLANs and network hosts within those segments. How does this happen? Convenience and mobility and general carelessness. Users copy information to places where they can work on it and end up copying it to systems outside of the intended VLAN domain or to different hosts on other VLANs. IT may even copy information for backup or test purposes. Either way, confidential information often ends up on unprotected “islands” that no one knows about until it’s too late. Network security based on VLAN technology can work if it’s done properly. And while it’s not perfect, it can add another layer of security to your environment, one that can make the difference between breach and no breach.

Tags Share this article 8/9/23 Published Firewall misconfigurations are one of the most common and preventable security issues that organizations face. Comprehensively managing access control, addressing vulnerabilities, and detecting configuration mistakes under these conditions is not easy It’s especially challenging for organizations that use the default firewall rules provided by their vendor. Your firewall policies should reflect your organization’s unique cybersecurity risk profile. This requires some degree of customization, and intelligence into kinds of cyber attacks hackers use to target your organization. Understanding security misconfigurations and their impact on network security Security misconfigurations happen when elements of your security tech stack expose preventable vulnerabilities that hackers can exploit. These misconfigurations can take a variety of forms, putting a wide range of security tools and open ports at risk. Network firewall misconfigurations can have a wide-ranging impact on your organization’s overall security posture. Hackers that target vulnerable infrastructure pose a threat to the entire application stack. They may be able to gain access to network services, application servers, and virtual machines. Depending on the specific misconfiguration, they may be able to compromise hardware routers and endpoints as well. In organizations with complex firewall deployments, attackers may be able to exploit misconfigurations, bypass security policies, and escalate their own privileges to make arbitrary changes to firewall security. From this point, attackers can easily modify access control lists (ACLs) to specifically allow the malware they wish to run, compromising the first line of defense against data breaches. This is exactly why Gartner recommends implementing a centralized solution for firewall management . Centralized visibility and control is crucial for maintaining effective firewall configurations and updating them accordingly. Otherwise, ensuring compliance with security best practices like the principle of least privilege becomes difficult or impossible. Routing network traffic through complex cloud-native infrastructure securely requires deep visibility into firewall configuration status, effective authentication processes, and automation-friendly security solutions. How hackers exploit misconfigured firewalls Common misconfigurations include implementing overly permissive rules, disabling critical security features, and neglecting to protect open ports against unauthorized access. This leaves organizations vulnerable to Distributed Denial-of-Service (DDoS) attacks, remote control, and data breaches . Here are some of the ways cybercriminals can exploit misconfigured firewalls: 1. Taking advantage of permissions misconfigurations Overly permissive firewall rules are a common problem among organizations with complex cloud-enabled infrastructure. Often, the organization’s demand for productivity and connectivity take precedence over the need to protect sensitive data from unauthorized network traffic. Additionally, IT team members may misunderstand the cloud provider’s shared responsibility model and assume that the provider has already secured the data center from all potential threats. These situations are particularly risky when the organization is undergoing change. For example, many security professionals start with completely open permissions and tighten them as they learn more about the network’s needs. Obvious and highly visible permissions get secured first, while less visible parts of the security framework are deprioritized – or never addressed at all. Hackers can exploit this situation by focusing on less obvious access points first. Instead of sending malicious traffic to IP addresses associated with core business servers, they might infiltrate the network through an unsecured API, or look for an unpatched operating system somewhere in the network. 2. Exploiting disabled security features Many firewalls offer advanced security features to organizations willing to configure them. However, security teams are often strained for time and resources. They may already be flooded with a backlog of high-priority security alerts to address, making it challenging to spend extra time configuring advanced firewall policies or fine-tuning their security posture. Even organizations that can enable advanced features don’t always do it. Features like leak detection and port scan alerts can put additional strain on limited computing resources, impacting performance. Other features may generate false positives, which only add to the security workload. But many of these features offer clear benefits to organizations that use them. Sophisticated technologies like application and identity-based inspection allow organizations to prioritize firewall performance more efficiently throughout the network. If threat actors find out that advanced security features like these are disabled, they are free to deploy the attack techniques these features protect against. For example, in the case of identity-based inspection, a hacker may be able to impersonate an unidentified administrator-level account and gain access to sensitive security controls without additional authentication. 3. Scanning for unsecured open ports Hackers use specialized penetration testing tools to scan for open ports. Tools like Nmap, Unicornscan , and Angry IP Scanner can find open ports and determine the security controls that apply to them. If a hacker finds out that your ACLs neglect to cover a particular port, they will immediately look for ways to exploit that vulnerability and gain access to your network. These tools are the same network discovery tools that system administrators and network engineers use on a routine basis. Tools like Nmap allow IT professionals to run security audits on local and remote networks, identifying hosts responding to network requests, discovering operating system names and versions, and more. Threat actors can even determine what kind of apps are running and find the version number of those apps. They also allow threat actors to collect data on weak points in your organization’s security defenses. For example, they might identify a healthcare organization using an outdated app to store sensitive clinical trial data. From there, it’s easy to look up the latest patch data to find out what exploits the outdated app is vulnerable to. How to optimize firewall configuration Protecting your organization from firewall breaches demands paying close attention to the policies, patch versions, and additional features your firewall provider offers. Here are three steps security leaders can take to address misconfiguration risks and ensure a robust security posture against external threats: 1. Audit your firewall policies regularly This is especially important for organizations undergoing the transition to cloud-native infrastructure. It’s virtually guaranteed that certain rules and permissions will no longer be needed as the organization adjusts to this period of change over time. Make sure that your firewall rules are constantly updated to address these changes and adapt to them accordingly. Auditing should take place under a strict change management framework . Implement a change log and incorporate it into your firewall auditing workflow so that you can easily access information about historical configuration changes. This change log will provide security professionals with readymade data about who implemented configuration changes, what time those changes took place, and why they were made in the first place. This gives you at-a-glance coverage of historical firewall performance, which puts you one step closer to building a unified, centralized solution for handling firewall policies. 2. Update and patch firewall software frequently Like every element in your security tech stack, firewall software needs to be updated promptly when developers release new patches. This applies both to hardware firewalls operating on-premises and software firewalls working throughout your network. These patches address known vulnerabilities, and they are often the first line of defense against rapidly emerging threats. The sooner you can deploy software patches to your firewalls, the more robust your network security posture will be. These changes should also be noted in a change log. This provides valuable evidence for the strength of your security posture against known emerging threats. If hackers start testing your defenses by abusing known post-patch vulnerabilities, you will be prepared for them. 3. Implement an intrusion detection system (IDS) Firewalls form the foundation of good network security, and intrusion detection systems supplement their capabilities by providing an additional line of defense. Organizations with robust IDS capabilities are much harder to compromise without triggering alerts. IDS solutions passively monitor traffic for signs of potential threats. When they detect a threat, they generate an alert, allowing security operations personnel to investigate and respond. This adds additional layers of value to the basic function of the firewall – allowing or denying traffic based on ACLs and network security rules. Many next-generation firewalls include intrusion detection system capabilities as part of an integrated solutions. This simplifies security management considerably and reduces the number of different devices and technologies security teams must gain familiarity with. Pay attention to firewall limitations – and prepare for them Properly configured firewalls offer valuable security performance to organizations with complex network infrastructure. However, they can’t prevent every cyber attack and block every bit of malicious code. Security leaders should be aware of firewall limitations and deploy security measures that compensate appropriately. Even with properly configured firewalls, you’ll have to address some of the following issues: Zero-day attacks Firewalls may not block attacks that exploit new and undiscovered vulnerabilities. Since these are not previously known vulnerabilities, security teams have not yet had time to develop patches or fixes that address them. These types of attacks are generally able to bypass more firewall solutions. However, some next-generation firewalls do offer advanced features capable of addressing zero-day attacks. Identity-based inspection is one example of a firewall technology that can detect these attacks because it enforces security policies based on user identity rather than IP address. Sandboxes are another next-generation firewall technology capable of blocking zero-day attacks. However, no single technology can reliably block 100% of all zero-day attacks. Some solutions are better-equipped to handle these types of attacks than others, but it takes a robust multi-layered security posture to consistently protect against unknown threats. Timely incident response Firewall configuration plays an important role in incident response. Properly configured firewalls help provide visibility into your security posture in real-time, enabling security teams to create high-performance incident response playbooks. Custom playbooks ensure timely incident response by prioritizing the types of threats found in real-world firewall data. If your firewalls are misconfigured, your incident response playbooks may reflect a risk profile that doesn’t match with your real-world security posture. This can lead to security complications that reduce the effectiveness of incident response processes down the line. Planned outages when updating firewalls Updating firewalls is an important part of maintaining an optimal firewall configuration for your organization. However, the update process can be lengthy. At the same time, it usually requires scheduling an outage in advance, which will temporarily expose your organization to the threats your firewall normally protects against. In some cases, there may be compatibility issues with incoming version of the firewall software being updated. This may lengthen the amount of time that the organization has to endure a service outage, which complicates firewall security. This is one reason why many security leaders intentionally delay updating their firewalls. As with many other aspects of running and maintaining good security policies, effective change management is an important aspect of planning firewall updates. Security leaders should stagger their scheduled updates to avoid reducing risk exposure and provide the organization with meaningful security controls during the update process.

Tags Share this article 11/15/21 Published In this guest blog, Jeff Yager from IT Central Station (soon to be PeerSpot), discusses how actual AlgoSec users have been able to securely accelerate their app delivery. These days, it is more important than ever for business owners, application owners, and information security professionals to speak the same language. That way, their organizations can deliver business applications more rapidly while achieving a heightened security posture. AlgoSec’s patented platform enables the world’s most complex organizations to gain visibility and process changes at zero-touch across the hybrid network. IT Central Station members discussed these benefits of AlgoSec , along with related issues, in their reviews on the site. Application Visibility AlgoSec allows users to discover, identify, map, and analyze business applications and security policies across their entire networks. For instance, Jacob S., an IT security analyst at a retailer, reported that the overall visibility that AlgoSec gives into his network security policies is high. He said, “It’s very clever in the logic it uses to provide insights, especially into risks and cleanup tasks . It’s very valuable. It saved a lot of hours on the cleanup tasks for sure. It has saved us days to weeks.” “AlgoSec absolutely provides us with full visibility into the risk involved in firewall change requests,” said Aaron Z. a senior network and security administrator at an insurance company that deals with patient health information that must be kept secure. He added, “There is a risk analysis piece of it that allows us to go in and run that risk analysis against it, figuring out what rules we need to be able to change, then make our environment a little more secure. This is incredibly important for compliance and security of our clients .” Also impressed with AlgoSec’s overall visibility into network security policies was Christopher W., a vice president – head of information security at a financial services firm, who said, “ What AlgoSec does is give me the ability to see everything about the firewall : its rules, configurations and usage patterns.” AlgoSec gives his team all the visibility they need to make sure they can keep the firewall tight. As he put it, “There is no perimeter anymore. We have to be very careful what we are letting in and out, and Firewall Analyzer helps us to do that.” For a cyber security architect at a tech services company, the platform helps him gain visibility into application connectivity flows. He remarked, “We have Splunk, so we need a firewall/security expert view on top of it. AlgoSec gives us that information and it’s a valuable contributor to our security environment.” Application Changes and Requesting Connectivity AlgoSec accelerates application delivery and security policy changes with intelligent application connectivity and change automation. A case in point is Vitas S., a lead infrastructure engineer at a financial services firm who appreciates the full visibility into the risk involved in firewall change requests. He said, “[AlgoSec] definitely allows us to drill down to the level where we can see the actual policy rule that’s affecting the risk ratings. If there are any changes in ratings, it’ll show you exactly how to determine what’s changed in the network that will affect it. It’s been very clear and intuitive.” A senior technical analyst at a maritime company has been equally pleased with the full visibility. He explained, “That feature is important to us because we’re a heavily risk-averse organization when it comes to IT control and changes. It allows us to verify, for the most part, that the controls that IT security is putting in place are being maintained and tracked at the security boundaries .” A financial services firm with more than 10 cluster firewalls deployed AlgoSec to check the compliance status of their devices and reduce the number of rules in each of the policies. According to Mustafa K. their network security engineer, “Now, we can easily track the changes in policies. With every change, AlgoSec automatically sends an email to the IT audit team. It increases our visibility of changes in every policy .” Speed and Automation The AlgoSec platform automates application connectivity and security policy across a hybrid network so clients can move quickly and stay secure. For Ilya K., a deputy information security department director at a computer software company, utilizing AlgoSec translates into an increase in security and accuracy of firewall rules. He said, “ AlgoSec ASMS brings a holistic view of network firewall policy and automates firewall security management in very large-sized environments. Additionally, it speeds up the changes in firewall rules with a vendor-agnostic approach.” “The user receives the information if his request is within the policies and can continue the request,” said Paulo A., a senior information technology security analyst at an integrator. He then noted, “Or, if it is denied, the applicant must adjust their request to stay within the policies. The time spent for this without AlgoSec is up to one week, whereas with AlgoSec, in a maximum of 15 minutes we have the request analyzed .” The results of this capability include greater security, a faster request process and the ability to automate the implementation of rules. Srdjan, a senior technical and integration designer at a large retailer, concurred when he said, “ By automating some parts of the work, business pressure is reduced since we now deliver much faster . I received feedback from our security department that their FCR approval process is now much easier. The network team is also now able to process FCRs much faster and with more accuracy.” To learn more about what IT Central Station members think about AlgoSec, visit https://www.itcentralstation.com/products/algosec-reviews Schedule a demo Related Articles Navigating Compliance in the Cloud AlgoSec Cloud Mar 19, 2023 · 2 min read 5 Multi-Cloud Environments Cloud Security Mar 19, 2023 · 2 min read Convergence didn’t fail, compliance did.

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”.

Tags Share this article 2/3/20 Published AlgoSec’s Integration with ServiceNow allows AlgoSec users to automate security change management and accelerate application deployments within their existing ServiceNow platform It isn’t easy for organizations to get holistic visibility and management across their increasingly complex, hybrid network environments. Application owners need to make changes to existing applications or launch new ones quickly to drive the business. Meanwhile, IT and security teams must maintain security, reduce the risk of outages and misconfigurations, and meet audit and compliance demands. It’s a difficult balance to achieve. In our 2019 cloud security survey , a lack of visibility into their entire network estate and seamless management of cloud and on-prem environments were two of the biggest challenges cited by organizations. Over 40% also reported having a network or application outage, with the leading cause being operational or human errors in making changes. So robust network security management and automation of processes are increasingly mission-critical. To manage network security changes efficiently, application owners prefer to use the familiar tools and workflows that they already know, while security owners need to understand the business context of the policies to ensure that they are making the right decisions to protect the organization’s assets. AlgoSec’s integration with ServiceNow’s IT Service Management solution allows these different stakeholders to share a single management. This bridges the gap between application and security teams and gives them both a holistic view of security, risk and compliance across their entire network environment. This, in turn, accelerates application delivery and strengthens the organization’s security and compliance postures. By integrating the AlgoSec Security Management Suite with ServiceNow, organizations can automate and enrich security policy change management while remaining entirely within the tool their team is already using, with the added benefit of business context. The solution works seamlessly with existing processes and workflows, which helps accelerate the rate of adoption across entire networks. Automating change management processes Making a single change in a complex enterprise environment could take days or even weeks. Using intelligent, highly customizable workflows, AlgoSec automates the entire security policy change process – from planning and design through to submission, proactive risk analysis, implementation, validation and auditing – all with zero-touch, enabling organizations to reduce change request processing times to minutes. By working with the tools that your organization is already familiar with, you don’t need to learn new workflows and user interfaces. Your application and IT teams can continue to use the tools they already know, and encourage organizational buy-in for automated network security policy change management.

Cloud Security 5 Multi-Cloud Environments 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 6/23/25 Published Top 5 misconfigurations to avoid for robust security Multi-cloud environments have become the backbone of modern enterprise IT, offering unparalleled flexibility, scalability, and access to a diverse array of innovative services. This distributed architecture empowers organizations to avoid vendor lock-in, optimize costs, and leverage specialized functionalities from different providers. However, this very strength introduces a significant challenge: increased complexity in security management. The diverse security models, APIs, and configuration nuances of each cloud provider, when combined, create a fertile ground for misconfigurations. A single oversight can cascade into severe security vulnerabilities, lead to compliance violations, and even result in costly downtime and reputational damage. At AlgoSec, we have extensive experience in navigating the intricacies of multi-cloud security. Our observations reveal recurring patterns of misconfigurations that undermine even the most well-intentioned security strategies. To help you fortify your multi-cloud defences, we've compiled the top five multi-cloud misconfigurations that organizations absolutely must avoid. 1. Over-permissive policies: The gateway to unauthorized access One of the most pervasive and dangerous misconfigurations is the granting of overly broad or permissive access policies. In the rush to deploy applications or enable collaboration, it's common for organizations to assign excessive permissions to users, services, or applications. This "everyone can do everything" approach creates a vast attack surface, making it alarmingly easy for unauthorized individuals or compromised credentials to gain access to sensitive resources across your various cloud environments. The principle of least privilege (PoLP) is paramount here. Every user, application, and service should only be granted the minimum necessary permissions to perform its intended function. This includes granular control over network access, data manipulation, and resource management. Regularly review and audit your Identity and Access Management (IAM) policies across all your cloud providers. Tools that offer centralized visibility into entitlements and highlight deviations can be invaluable in identifying and rectifying these critical vulnerabilities before they are exploited. 2. Inadequate network segmentation: Lateral movement made easy In a multi-cloud environment, a flat network architecture is an open invitation for attackers. Without proper network segmentation, a breach in one part of your cloud infrastructure can easily lead to lateral movement across your entire environment. Mixing production, development, and sensitive data workloads within the same network segment significantly increases the risk of an attacker pivoting from a less secure development environment to a critical production database. Effective network segmentation involves logically isolating different environments, applications, and data sets. This can be achieved through Virtual Private Clouds (VPCs), subnets, security groups, network access control lists (NACLs), and micro-segmentation techniques. The goal is to create granular perimeters around critical assets, limiting the blast radius of any potential breach. By restricting traffic flows between different segments and enforcing strict ingress and egress rules, you can significantly hinder an attacker's ability to move freely within your cloud estate. 3. Unsecured storage buckets: A goldmine for data breaches Cloud storage services, such as Amazon S3, Azure Blob Storage, and Google Cloud Storage, offer incredible scalability and accessibility. However, their misconfiguration remains a leading cause of data breaches. Publicly accessible storage buckets, often configured inadvertently, expose vast amounts of sensitive data to the internet. This includes customer information, proprietary code, intellectual property, and even internal credentials. It is imperative to always double-check and regularly audit the access controls and encryption settings of all your storage buckets across every cloud provider. Implement strong bucket policies, restrict public access by default, and enforce encryption at rest and in transit. Consider using multifactor authentication for access to storage, and leverage tools that continuously monitor for publicly exposed buckets and alert you to any misconfigurations. Regular data classification and tagging can also help in identifying and prioritizing the protection of highly sensitive data stored in the cloud. 4. Lack of centralized visibility: Flying blind in a complex landscape Managing security in a multi-cloud environment without a unified, centralized view of your security posture is akin to flying blind. The disparate dashboards, logs, and security tools provided by individual cloud providers make it incredibly challenging to gain a holistic understanding of your security landscape. This fragmented visibility makes it nearly impossible to identify widespread misconfigurations, enforce consistent security policies across different clouds, and respond effectively and swiftly to emerging threats. A centralized security management platform is crucial for multi-cloud environments. Such a platform should provide comprehensive discovery of all your cloud assets, enable continuous risk assessment, and offer unified policy management across your entire multi-cloud estate. This centralized view allows security teams to identify inconsistencies, track changes, and ensure that security policies are applied uniformly, regardless of the underlying cloud provider. Without this overarching perspective, organizations are perpetually playing catch-up, reacting to incidents rather than proactively preventing them. 5. Neglecting Shadow IT: The unseen security gaps Shadow IT refers to unsanctioned cloud deployments, applications, or services that are used within an organization without the knowledge or approval of the IT or security departments. While seemingly innocuous, shadow IT can introduce significant and often unmanaged security gaps. These unauthorized resources often lack proper security configurations, patching, and monitoring, making them easy targets for attackers. To mitigate the risks of shadow IT, organizations need robust discovery mechanisms that can identify all cloud resources, whether sanctioned or not. Once discovered, these resources must be brought under proper security governance, including regular monitoring, configuration management, and adherence to organizational security policies. Implementing cloud access security brokers (CASBs) and network traffic analysis tools can help in identifying and gaining control over shadow IT instances. Educating employees about the risks of unauthorized cloud usage is also a vital step in fostering a more secure multi-cloud environment. Proactive management with AlgoSec Cloud Enterprise Navigating the complex and ever-evolving multi-cloud landscape demands more than just awareness of these pitfalls; it requires deep visibility and proactive management.
