VLAN security best practices Kevin Beaver 2 min read Kevin Beaver 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 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.

  • AlgoSec | Firewall has detected a new network

    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.

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 Horizon Security 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. Horizon AppViz 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 Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Firewall Change Management How to secure your LAN (Local Area Network) Matthew Pascucci 2 min read Matthew Pascucci 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 11/12/13 Published How to Secure Your Local Area Network In my last blog series we reviewed ways to protect the perimeter of your network and then we took it one layer deeper and discussed securing the DMZ . Now I’d like to examine the ways you can secure the Local Area Network, aka LAN, also known as the soft underbelly of the beast. Okay, I made that last part up, but that’s what it should be called. The LAN has become the focus of attack over the past couple years, due to companies tightening up their perimeter and DMZ. It’s very rare you’ll you see an attacker come right at you these days, when they can trick an unwitting user into clicking a weaponized link about “Cat Videos” (Seriously, who doesn’t like cat videos?!). With this being said, let’s talk about a few ways we can protect our soft underbelly and secure our network. For the first part of this blog series, let’s examine how to secure the LAN at the network layer. LAN and the Network Layer From the network layer, there are constant things that can be adjusted and used to tighten the posture of your LAN. The network is the highway where the data traverses. We need protection on the interstate just as we need protection on our network. Protecting how users are connecting to the Internet and other systems is an important topic. We could create an entire series of blogs on just this topic, but let’s try to condense it a little here. Verify that you’re network is segmented – it better be if you read my last article on the DMZ – but we need to make sure nothing from the DMZ is relying on internal services. This is a rule. Take them out now and thank us later. If this is happening, you are just asking for some major compliance and security issues to crop up. Continuing with segmentation, make sure there’s a guest network that vendors can attach to if needed. I hate when I go to a client/vendor’s site and they ask me to plug into their network. What if I was evil? What if I had malware on my laptop that’s now ripping throughout your network because I was dumb enough to click a link to a “Cat Video”? If people aren’t part of your company, they shouldn’t be connecting to your internal LAN plain and simple. Make sure you have egress filtering on your firewall so you aren’t giving complete access for users to pillage the Internet from your corporate workstation. By default users should only have access to port 80/443, anything else should be an edge case (in most environments). If users need FTP access there should be a rule and you’ll have to allow them outbound after authorization, but they shouldn’t be allowed to rush the Internet on every port. This stops malware, botnets, etc. that are communicating on random ports. It doesn’t protect everything since you can tunnel anything out of these ports, but it’s a layer! Set up some type of switch security that’s going to disable a port if there are different or multiple MAC addresses coming from a single port. This stops hubs from being installed in your network and people using multiple workstations. Also, attempt to set up NAC to get a much better understating of what’s connecting to your network while giving you complete control of those ports and access to resources from the LAN. In our next LAN security-focused blog, we’ll move from the network up the stack to the application layer.

Cloud Security Understanding and Preventing Kubernetes Attacks and Threats Ava Chawla 2 min read Ava Chawla Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 10/20/21 Published As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy, and scale containers across different machines. The bad news is that cybercriminals have figured out how to exploit the platform’s vulnerabilities , resulting in catastrophic network intrusions across many company infrastructures. A recent report revealed that 94% of respondents reported security incidents in Kubernetes environments. The question is, what is behind this surge of Kubernetes attacks, and how can they be prevented? How Kubernetes is Vulnerable As a container-based platform, a new set of vulnerabilities, permission issues, and specific images set the stage for the increase in attacks. The threats have included fileless malware in containers, leveraging misconfigured Docker API ports, and using container images for attacks. Misconfigured Docker API Ports Exploitation Scanning for misconfigured Docker API ports and using them for deploying images containing malware is a relatively new type of attack. The malware, designed to evade static scanning, has become a popular method to hijack compute cycles for fraudulent cryptomining. This cryptojacking activity steals CPU power to mine currencies such as Ethereum and Monero. By first identifying vulnerable front-end websites and other systems, attackers send a command through the application layer simply by manipulating a domain’s text field or through an exposed API in the website’s URL. The code then enters the container, where it is executed with commands sent to a Docker container’s shell. A wget command is executed to download the malware. To protect against this attack, enterprises must ensure their container files are not writable, establish CPU consumption limits, and enable alerts to detect interactive shell launches. DDoS Attacks With Open Docker Daemons Cybercriminals use misconfigured open Docker daemons to launch DDoS attacks using a botnet of containers. UDP flood and Slowloris were recently identified as two such types of container-based botnet attacks. A recent blog describes an anatomy of these Kubernetes attacks. The attackers first identified open Docker daemons using a scanning tool such as Shodan to scan the internet for IP addresses and find a list of hosts, open ports, and services. By uploading their own dedicated images to the Docker hub, they succeeded in deploying and remotely running the images on the host. Analyzing how the UDP flood attack was orchestrated required an inspection of the binary with IDA. This revealed the start_flood and start_tick threads. The source code for the attack was found on Github. This code revealed a try_gb parameter, with the range of 0 to 1,024, used to configure how much data to input to flood the target. However, it was discovered that attackers are able to modify this open-source code to create a self-compiled binary that floods the host with even greater amounts of UDP packets. In the case of the Slowloris attack, cybercriminals launched DDoS with the slowhttptest utility. The attackers were able to create a self-compiling binary that is unidentifiable in malware scans. Protection from these Kubernetes attacks requires vigilant assurance policies and prevention of images other than compliant ones to run in the system. Non-compliant images will then be blocked when intrusion attempts are made. Man in the Middle Attacks With LoadBalancer or ExternalIPs An attack affecting all versions of Kubernetes involves multi-tenant clusters. The most vulnerable clusters have tenants that are able to create and update services and pods. In this breach, the attacker can intercept traffic from other pods or nodes in the cluster by creating a ClusterIP service and setting the spec.externalIP’s field. Additionally, a user who is able to patch the status of a LoadBalancer service can grab traffic. The only way to mitigate this threat is to restrict access to vulnerable features. This can be done with the admission webhook container, externalip-webhook , which prevents services from using random external IPs. An alternative method is to lock external IPs with OPA Gatekeeper with this sample Constraint Templatecan. Siloscape Malware Security researcher, Daniel Prizmant, describes a newer malware attack that he calls Siloscape. Its primary goal is to escape the container that is mainly implemented in Windows server silo. The malware targets Kubernetes through Windows containers to open a backdoor into poorly configured clusters to run the malicious containers. While other malware attacks focus on cryptojacking, the Siloscape user’s motive is to go undetected and open a backdoor to the cluster for a variety of malicious activities. This is possible since Siloscape is virtually undetectable due to a lack of readable strings in the binary. This type of attack can prove catastrophic. It compromises an entire cluster running multiple cloud applications. Cybercriminals can access critical information including sign-ins, confidential files, and complete databases hosted inside the cluster. Additionally, organizations using Kubernetes clusters for testing and development can face catastrophic damage should these environments be breached. To prevent a Siloscape attack, it is crucial that administrators ensure their Kubernetes clusters are securely configured. This will prevent the malware from creating new deployments and force Siloscape to exit. Microsoft also recommends using only Hyper-V containers as a security boundary for anything relying on containerization. The Threat Matrix The MITRE ATT&CK database details additional tactics and techniques attackers are using to infiltrate Kubernetes environments to access sensitive information, mine cryptocurrency, perform DDoS attacks, and other unscrupulous activities. The more commonly used methods are as follows: 1. Kubernetes file compromise Because this file holds sensitive data such as cluster credentials, an attacker could easily gain initial access to the entire cluster. Only accept kubeconfig files from trusted sources. Others should be thoroughly inspected before they are deployed. 2. Using similar pod names Attackers create similar pod names and use random suffixes to hide them in the cluster. The pods then run malicious code and obtain access to many other resources. 3. Kubernetes Secrets intrusion Attackers exploit any misconfigurations in the cluster with the goal of accessing the API server and retrieving information from the Secrets objects. 4. Internal network access Attackers able to access a single pod that communicates with other pods or applications can move freely within the cluster to achieve their goals. 5. Using the writeable hostPath mount Attackers with permissions to create new containers can create one with a writeable hostPath volume. Kubernetes Attacks: Key Takeaways Kubernetes brings many advantages to organizations but also presents a variety of security risks, as documented above. However, by ensuring their environments are adequately protected through proper configuration and appropriately assigned permissions, the threat of Kubernetes attacks is greatly minimized. Should a container be compromised, properly assigned privileges can severely limit a cluster-wide compromise.

  • Best Practices for Amazon Web Services Security | algosec

    Security Policy Management with Professor Wool Best Practices for Amazon Web Services Security Best Practices for Amazon Web Services (AWS) Security is a whiteboard-style series of lessons that examine the challenges of and provide technical tips for managing security across hybrid data centers utilizing the AWS IaaS platform. Lesson 1 In this lesson Professor Wool provides an overview of Amazon Web Services (AWS) Security Groups and highlights some of the differences between Security Groups and traditional firewalls. The lesson continues by explaining some of the unique features of AWS and the challenges and benefits of being able to apply multiple Security Groups to a single instance. The Fundamentals of AWS Security Groups Watch Lesson 2 Outbound traffic rules in AWS Security Groups are, by default, very wide and insecure. In addition, during the set-up process for AWS Security Groups the user is not intuitively guided through a set up process for outbound rules – the user must do this manually. In this lesson, Professor Wool, highlights the limitations and consequences of leaving the default rules in place, and provides recommendations on how to define outbound rules in AWS Security Groups in order to securely control and filter outbound traffic and protect against data leaks. Protect Outbound Traffic in an AWS Hybrid Environment Watch Lesson 3 Once you start using AWS for production applications, auditing and compliance considerations come into play, especially if these applications are processing data that is subject to regulations such as PCI, HIPAA, SOX etc. In this lesson, Professor Wool reviews AWS’s own auditing tools, CloudWatch and CloudTrail, which are useful for cloud-based applications.
