- Firewall Management 201 | algosec
Security Policy Management with Professor Wool Firewall Management 201 Firewall Management with Professor Wool is a whiteboard-style series of lessons that examine the challenges of and provide technical tips for managing security policies in evolving enterprise networks and data centers. Lesson 1 In this lesson, Professor Wool discusses his research on different firewall misconfigurations and provides tips for preventing the most common risks. Examining the Most Common Firewall Misconfigurations Watch Lesson 2 In this lesson, Professor Wool examines the challenges of managing firewall change requests and provides tips on how to automate the entire workflow. Automating the Firewall Change Control Process Watch Lesson 3 In this lesson, Professor Wool offers some recommendations for simplifying firewall management overhead by defining and enforcing object naming conventions. Using Object Naming Conventions to Reduce Firewall Management Overhead Watch Lesson 4 In this lesson, Professor Wool examines some tips for including firewall rule recertification as part of your change management process, including questions you should be asking and be able to answer as well as guidance on how to effectively recertify firewall rules Tips for Firewall Rule Recertification Watch Lesson 5 In this lesson, Professor Wool examines how virtualization, outsourcing of data centers, worker mobility and the consumerization of IT have all played a role in dissolving the network perimeter and what you can do to regain control. Managing Firewall Policies in a Disappearing Network Perimeter Watch Lesson 6 In this lesson, Professor Wool examines some of the challenges when it comes to managing routers and access control lists (ACLs) and provides recommendations for including routers as part of your overall security policy with tips on change management, auditing and ACL optimization. Analyzing Routers as Part of Your Security Policy Watch Lesson 7 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. Examining the Challenges of Accurately Simulating Network Routing Watch Lesson 8 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. NAT Considerations When Managing Your Security Policy Watch Lesson 9 In this lesson, Professor Wool explains how you can create templates - using network objects - for different types of services and network access which are reused by many different servers in your data center. Using this technique will save you from writing new firewall rules each time you provision or change a server, reduce errors, and allow you to provision and expand your server estate more quickly. How to Structure Network Objects to Plan for Future Policy Growth Watch Lesson 10 In this lesson, Professor Wool examines the challenges of migrating business applications and physical data centers to a private cloud and offers tips to conduct these migrations without the risk of outages. Tips to Simplify Migrations to a Virtual Data Center Watch Lesson 11 In this lesson, Professor Wool provides the example of a virtualized private cloud which uses hypervisor technology to connect to the outside world via a firewall. If all worksloads within the private cloud share the same security requirements, this set up is adequate. But what happens if you want to run workloads with different security requirements within the cloud? Professor Wool explains the different options for filtering traffic within a private cloud, and discusses the challenges and solutions for managing them. Tips for Filtering Traffic within a Private Cloud Watch Lesson 12 In this lesson Professor Wool discusses ways to ensure that your security policy on your primary site and on your disaster recovery (DR) site are always sync. He presents multiple scenarios: where the DR and primary site use the exact same firewalls, where different vendor solutions or different models are used on the DR site, and where the IP address is or is not the same on the two sites. Managing Your Security Policy for Disaster Recovery Watch Lesson 13 In this lesson, Professor Wool highlights the challenges, benefits and trade-offs of utilizing zero-touch automation for security policy change management. He explains how, using conditional logic, its possible to significantly speed up security policy change management while maintaining control and ensuring accuracy throughout the process. Zero-Touch Change Management with Checks and Balances Watch Lesson 14 Many organizations have different types of firewalls from multiple vendors, which typically means there is no single source for naming and managing network objects. This ends up creating duplication, confusion, mistakes and network connectivity problems especially when a new change request is generated and you need to know which network object to refer to. In this lesson Profession Wool provides tips and best practices for how to synchronize network objects in a multi-vendor environment for both legacy scenarios, and greenfield scenarios. Synchronized Object Management in a Multi-Vendor Environment Watch Lesson 15 Many organizations have both a firewall management system as well as a CMDB, yet these systems do not communicate with each other and their data is not synchronized. This becomes a problem when making security policy change requests, and typically someone needs to manually translate the names used by in the firewall management system to the name in the CMDB, which is a slow and error-prone process, in order for the change request to work. In this lesson Professor Wool provides tips on how to use a network security policy management to coordinate between the two system, match the object names, and then automatically populate the change management process with the correct names and definitions. How to Synchronize Object Management with a CMDB Watch Lesson 16 Some companies use tools to automatically convert firewall rules from an old firewall, due to be retired, to a new firewall. In this lesson, Professor Wool explains why this process can be risky and provides some specific technical examples. He then presents a more realistic way to manage the firewall rule migration process that involves stages and checks and balances to ensure a smooth, secure transition to the new firewall that maintains secure connectivity. How to Take Control of a Firewall Migration Project Watch Lesson 17 PCI-DSS 3.2 regulation requirement 6.1 mandates that organizations establish a process for identifying security vulnerabilities on the servers that are within the scope of PCI. In this new lesson, Professor Wool explains how to address this requirement by presenting vulnerability data by both the servers and the by business processes that rely on each server. He discusses why this method is important and how it allows companies to achieve compliance while ensuring ongoing business operations. PCI – Linking Vulnerabilities to Business Applications Watch Lesson 18 Collaboration tools such as Slack provide a convenient way to have group discussions and complete collaborative business tasks. Now, these automated chatbots can be used for answering questions and handling tasks for development, IT and infosecurity teams. For example, enterprises can use chatbots to automate information-sharing across silos, such as between IT and application owners. So rather than having to call somebody and ask them “Is that system up? What happened to my security change request?” and so on, tracking helpdesk issues and the status of help requests can become much more accessible and responsive. Chatbots also make access to siloed resources more democratic and more widely available across the organization (subject, of course to the necessary access rights). In this video, Prof. Wool discusses how automated chatbots can be used to help a wide range of users for their security policy management tasks – thereby improving service to stakeholders and helping to accelerate security policy change processes across the enterprise.

- Next Generation Firewalls | algosec
Security Policy Management with Professor Wool Next Generation Firewalls Next Generation Firewalls (NGFWs) with Professor Wool is a whiteboard-style series of lessons that examine the some of the challenges of and provide technical tips for managing security policies on NGFWs across in evolving enterprise networks and data centers. Lesson 1 In this lesson, Professor Wool examines next-generation firewalls and the granular capabilities they provide for improved control over applications and users. Next-Generation Firewalls: Overview of Application and User-Aware Policies Watch Lesson 2 In this lesson, Professor Wool examines the pros and cons of whitelisting and blacklisting policies and offers some recommendations on policy considerations. NGFWs – Whitelisting & Blacklisting Policy Considerations Watch Lesson 3 Next generation firewalls (NGFWs) allow you to manage security policies with much greater granularity, based on specific applications and users, which provides much greater control over the traffic you want to allow or deny. Today, NGFWs are usually deployed alongside traditional firewalls. Therefore change requests need to be written using each firewall type’s specific terminology; application names and default ports for NGFWs, and actual protocols and ports for traditional firewalls. This new lesson explains some of challenges of writing firewall rules for a mixed firewall environment, and how to address them. Managing Your Security Policy in a Mixed Next Gen and Traditional Firewall Environment Watch Lesson 4 As part of the blacklisting approach to application security, most NGFW vendors now offer their customers a subscription based service that provides periodic updates to firewall definitions and signatures for a great number of applications especially the malicious ones. In this lesson, Professor Wool discusses the pros and cons of this offering for cyber threat prevention. It also discusses the limitations of this service when home-grown applications are deployed in the enterprise, and provides a recommendation on how to solve this problem.

DevSecOps Why organizations need to embrace new thinking in how they tackle hybrid cloud security challenges Prof. Avishai Wool 2 min read Prof. Avishai Wool 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 10/9/22 Published Hybrid cloud computing enables organizations to deploy sensitive workloads on-premise or in a private cloud, while hosting less business-critical resources on public clouds. But despite its many benefits, the hybrid environment also creates security concerns. AlgoSec’s co-founder and CTO, Prof. Avishai Wool shares his expert insights on these concerns and offers best practices to boost hybrid cloud security. Hybrid cloud computing combines on-premises infrastructure, private cloud services, and one or more public clouds. Going hybrid provides businesses with enhanced flexibility, agility, cost savings, and scalability to innovate, grow, and gain a competitive advantage. So, how can you simplify and strengthen security operations in the hybrid cloud? It all starts with visibility – you still can’t protect what you can’t see To protect their entire hybrid infrastructure, applications, workloads, and data, security teams need to know what these assets are and where they reside. They also need to see the entire hybrid estate and not just the individual elements. However, complete visibility is a serious hybrid cloud security challenge. Hybrid environments are highly complex, which can create security blind spots, which then prevent teams from identifying, evaluating, and most importantly, mitigating risk. Another hybrid cloud security concern is that you cannot implement a fragmented security approach to control the entire network. With thousands of integrated and inter-dependent resources and data flowing between them, vulnerabilities crop up, increasing the risk of cyberattacks or breaches. For complete hybrid cloud security, you need a holistic approach that can help you control the entire network. Is DevSecOps the panacea? Not quite In many organizations, DevSecOps teams manage cloud security because they have visibility into what’s happening inside the cloud. However, in the hybrid cloud, many applications have servers or clients existing outside the cloud, which DevSecOps may not have visibility into. Also, the protection of data flowing into and out of the cloud is not always under their remit. To make up for these gaps, other teams are required to manage security operations and minimize hybrid cloud risks. These additional processes and team members must be coordinated to ensure continuous security across the entire hybrid network environment. But this is easier said than done. Using IaC to balance automation with oversight is key, but here’s why you shouldn’t solely rely on it Infrastructure as code (IaC) will help you automatically deploy security controls in the hybrid cloud to prevent misconfiguration errors, non-compliance, and violations while in the production stage and pre application testing. With IaC-based security, you can define security best practices in template files, which will minimize risks and enhance your security posture. But there’s an inherent risk in putting all your eggs in the automation and IaC basket. Due to the fact that all the controls are on the operational side, it can create serious hybrid cloud security issues. And without human attention and action, vulnerabilities may remain unaddressed and open the door to cyberattacks. Since security professionals who are not on the operational side must oversee the cloud environment, it could easily open the door to miscommunication and human errors – a very costly proposition for organizations. For this very reason, you should also implement a process to regularly deploy automatic updates without requiring time-consuming approvals that slow down workflows and weaken security. Strive for 95% automated changes and only involve a person for the remaining 5% that requires human input. Hybrid cloud security best practices – start early, start strong When migrating from on-prem to the cloud, you can choose a greenfield migration or a lift-and-shift migration. Greenfield means rolling out a brand-new application. In this case, ensure that security considerations are “baked in” from the beginning and across all processes. This “shift left” approach helps build an environment that’s secure from the get-go. This ensures that all team members adhere to a unified set of security policy rules to minimize vulnerabilities and reduce security risks within the hybrid cloud environment. If you lift-and-shift on-prem applications to the cloud, note any security assumptions made when they were designed. This is important because they were not built for the cloud and may incorporate protocols that increase security risks. Next, implement appropriate measures during migration planning. For example, implement an Application Load Balancer if applications leverage plaintext protocols, and use sidecars to encrypt applications without having to modify the original codebase. You can also leverage hybrid cloud security solutions to detect and mitigate security problems in real-time. Matching your cloud security with application structure is no longer optional Before moving to a hybrid cloud, map the business logic, application structure, and application ownership into the hybrid cloud estate’s networking structure. To simplify this process, here are some tried and proven ways to consider. Break up your environment into a virtual private cloud (VPC) or virtual network. With the VPC, you can monitor connections, screen traffic, create multiple subnets, and also restrict instance access to improve security posture. Use networking constructs to segregate applications into different functional and networking areas in the cloud. This way, you can deploy network controls to segment your cloud estate and ensure that only authorized users can access sensitive data and resources. Tag all resources based on their operating system, business unit, and geographical area. Tags with descriptive metadata can help to identify resources. They also establish ownership and accountability, provide visibility into cloud consumption, and help with the deployment of security policies. Conclusion In today’s fast-paced business environment, hybrid cloud computing can benefit your organization in many ways. But to capture these benefits, you should make an effort to boost hybrid cloud security. Incorporate the best practices discussed here to improve security and take full advantage of your hybrid environment.

Firewall Change Management NGFW vs UTM: What you need to know Sam Erdheim 2 min read Sam Erdheim 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 2/19/13 Published Podcast: Differences between UTM and NGFW In our recent webcast discussion alongside panelists from Fortinet, NSS Labs and General Motors, we examined the State of the Firewall in 2013. We received more audience questions during the webcast than the time allowed for, so we’d like to answer these questions through several blog posts in a Q&A format with the panelists. By far the most asked question leading up to and during the webcast was: “What’s the difference between a UTM and a Next-Generation Firewall?” Here’s how our panelists responded: Pankil Vyas, Manager – Network Security Center, GM UTM are usually bundled feature set, NGFW has bundle but licensing can be selective. Depending on the firewall’s function on the network, some UTM features might not be useful, creating performance issues and sometimes firewall conflicts with packet flows. Nimmy Reichenberg, VP of Strategy, AlgoSec Different people give different answers to this question, but if we refer to Gartner who are certainly a credible source, a UTM consolidates many security functions (email security, AV, IPS, URL filtering etc.) and is tailored mostly to SMBs in terms of management capabilities, throughput, support, etc. A NGFW is an enterprise-grade product that at the very least includes IPS capabilities and application awareness (layer 7 control). You can refer to a Gartner paper titled “Defining the Next-Generation Firewall” for more information. Ryan Liles, Director of Testing Services, NSS Labs There really aren’t any differences in a UTM and a NGFW. The technologies used in the two are essentially the same, and they generally have the same capabilities. UTM devices are typically classified with lower throughput ratings than their NGFW counterparts, but for all practical purposes the differences are in marketing. The term NGFW was coined by vendors working with Gartner to create a class of products capable of fitting into an enterprise network that contained all of the features of a UTM. The reason for the name shift is that there was a pervasive line of thought stating a device capable of all of the functions of a UTM/NGFW would never be fast enough to run in an enterprise network. As hardware has progressed, the capability of these devices to hit multi-gigabit speeds began to prove that they were indeed capable of enterprise deployment. Rather than try and fight the sentiment that a UTM could never fit into an enterprise, the NGFW was born. Patrick Bedwell, VP of Products, Fortinet There are several definitions in the market of both terms. Analyst firms IDC and Gartner provided the original definitions of the terms. IDC defined UTM as a security appliance that combines firewall, gateway antivirus, and intrusion detection / intrusion prevention (IDS/IPS). Gartner defined an NGFW as a single device with integrated IPS with deep packet scanning, standard first-generation FW capabilities (NAT, stateful protocol inspection, VPN, etc.) and the ability to identity and control applications running on the network. Since their initial definitions, the terms have been used interchangeably by customers as well as vendors. Depending on with whom you speak, UTM can include NGFW features like application ID and control, and NGFW can include UTM features like gateway antivirus. The terms are often used synonymously, as both represent a single device with consolidated functionality. At Fortinet, for example, we offer customers the ability to deploy a FortiGate device as a pure firewall, an NGFW (enabling features like Application Control or User- and Device-based policy enforcement) or a full UTM (enabling additional features like gateway AV, WAN optimization, and so forth). Customers can deploy as much or as little of the technology on the FortiGate device as they need to match their requirements. If you missed the webcast, you can view it on-demand.

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.
