Tags Share this article 11/25/24 Published Azure Security Best Practices: Don't Get Caught with Your Cloud Pants Down Executive Summary The cloud isn't some futuristic fantasy anymore, folks. It's the backbone of modern business, and Azure is charging hard, fueled by AI, to potentially dethrone AWS by 2026. But with this breakneck adoption comes a harsh reality: security can't be an afterthought. This article dives deep into why robust security practices are non-negotiable in Azure and how tools like Microsoft Sentinel and Defender XDR can be your digital bodyguards. Introduction Let's face it, organizations are flocking to the cloud like moths to a digital flame. Why? Cost savings, streamlined operations, and the ability to scale at warp speed. We're talking serious money here – a projected $805 billion spent on public cloud services in 2024! The cloud's not just disrupting the game; it is the game. And the playing field is shifting. AWS might be the king of the hill right now, but Azure's hot on its heels, thanks to some serious AI muscle. ( As of 2024, they hold market shares of 31%, 24%, and 11%, respectively .) Forbes even predicts an Azure takeover by 2026. Exciting times, right? Hold your horses. This rapid cloud adoption has a dark side. Security threats are lurking around every corner, and sticking to best practices is more crucial than ever. Cloud service managers, listen up: you need to wrap your heads around the shared responsibility model (Figure 1). Think of it like this: you and Azure are partners in crime prevention. You're both responsible for keeping your digital assets safe, but you need to know who's holding which piece of the security puzzle. Don't assume security is built-in – it's a team effort, and you need to pull your weight. Figure 1: The shared responsibility model Azure's Security Architecture: A Fortress in the Cloud Okay, I get it. The shared responsibility model can feel like navigating a maze blindfolded. But here's the deal: whether you're dabbling in IaaS, PaaS, or SaaS, Azure's got your infrastructure covered. Their global network of data centers is built like Fort Knox, meeting industry standards like ISO/IEC 27001:2022 , HIPAA , and NIST SP 800-53 . But remember your part of the bargain! Azure provides a killer arsenal of security products to protect your workloads, both in Azure and beyond. Figure 2: Azure’s security architecture Take Microsoft Sentinel, for example. This superhero of a tool automatically sniffs out threats, investigates them, and neutralizes them before they can wreak havoc. It's like having a 24/7 security team with superhuman senses. And don't forget about Microsoft Defender XDR. This comprehensive security suite is like a digital Swiss Army knife, protecting your identities, endpoints, applications, email, and cloud apps. It's got your back, no matter where you turn. With Sentinel and Defender XDR in your corner, you're well-equipped to tackle the security challenges that come with cloud adoption. But don't get complacent! Let's dive into some core security best practices that will make your Azure environment an impenetrable fortress. Core Security Best Practices: Lock Down Your Secrets Protecting Secrets: Best Practices Using Azure Key Vault We all have secrets, right? In the digital world, those secrets are things like passwords, API keys, and encryption keys. You can't just leave them lying around for any cybercriminal to snatch. That's where Azure Key Vault comes in. This secure vault is like a digital safe deposit box for your sensitive data. It uses hardware security modules (HSMs) to keep your secrets locked down tight, even if someone manages to breach your defenses. Big names like Victoria's Secret & Co , Evup, and Sage trust Key Vault to keep their secrets safe. Figure 3: A new Key Vault named “algosec-kv” Here's a pro tip: once you've stashed your secrets in Key Vault, use a managed identity to access them. This eliminates the need to hardcode credentials in your code, minimizing the risk of exposure. var client = new SecretClient(new Uri("https://. vault.azure.net/ "), new DefaultAzureCredential(),options); KeyVaultSecret secret = client.GetSecret(""); string secretValue = secret.Value; Key Vault is a fantastic tool, but it's not a silver bullet. Download our checklist of additional best practices to keep your secrets safe: Database and Data Security: More Than Just Locking the Door Azure offers a smorgasbord of data storage solutions, from Azure SQL Database to Azure Blob Storage. But securing your data isn't just about protecting it at rest. You need to think about data in use and data in transit, too. Download our checklist for a full action plan: Identity Management: Who Are You, and What Are You Doing Here? Encryption is great, but it's only half the battle. You need to know who's accessing your resources and what they're doing. That's where identity access management (IAM) comes in. Think of IAM as a digital bouncer, controlling access to your network resources. It's all about verifying identities and granting the right level of access – no more, no less. Zero-trust network access (ZTNA) is your secret weapon here. It's like having a security checkpoint at every corner of your network, ensuring that only authorized users can access your resources. Figure 4: Zero-trust security architecture Remember the Capital One breach? A misconfigured firewall and overly broad permissions led to a massive data leak. Don't let that be you! Follow Azure's IAM documentation to build a robust and secure identity management system. Network Security: Building a Digital Moat Your network architecture is the foundation of your security posture. Choose wisely, my friends! The hub-spoke model is a popular choice in Azure, centralizing common services in a secure hub and isolating workloads in separate spokes. Figure 5: Hub-spoke network architecture in Azure (Source: Azure documentation ) For a checklist of how the hub-spoke model can boosts your security, download our checklist here. Digital Realty , a real estate investment giant, uses the hub-spoke model to secure its global portal and REST APIs. It's a testament to the power of this architecture for both security and performance. Figure 6: Digital Realty’s use of hub-spoke architecture (Adapted from Microsoft Customer Stories ) Operational Security: Stay Vigilant, Stay Secure (Continued) When a security incident strikes, your response time is critical. Think of operational security as your digital first aid kit. It's about minimizing human error and automating processes to speed up threat detection and response. We've already talked about MFA, password management, and the dynamic duo of Defender XDR and Sentinel. Download our checklist for a few more operational security essentials to add to your arsenal. Figure 7: Build-deploy workflow automation (Source: Azure documentation ) Think of these best practices as guardrails, guiding you toward secure decisions. But remember, flexibility is key. Adapt these practices to your specific environment and architecture. Conclusion As Azure's popularity skyrockets, so do the stakes. The shared responsibility model means you're not off the hook when it comes to security. Azure provides powerful tools like Sentinel and Defender XDR, but it's up to you to use them wisely and follow best practices. Protect your secrets like they're buried treasure, secure your data with Fort Knox-level encryption, implement identity management that would make a border patrol agent proud, and build a network architecture that's a digital fortress. And don't forget about operational security – it's the glue that holds it all together. But let's be real, managing security policies across multiple clouds can be a nightmare. That's where tools like AlgoSec CloudFlow come in. They provide a clear view of your security landscape, helping you identify vulnerabilities and streamline policy management. It's like having a security command center for your entire cloud infrastructure. So, what are you waiting for?

Tags Share this article 12/1/20 Published Yitzy Tannenbaum, Product Marketing Manager at AlgoSec, discusses how AWS customers can leverage AlgoSec for AWS to easily migrate applications Public cloud platforms bring a host of benefits to organizations but managing security and compliance can prove complex. These challenges are exacerbated when organizations are required to manage and maintain security across all controls that make up the security network including on-premise, SDN and in the public cloud. According to a Gartner study , 81% of organizations are concerned about security, and 57% about maintaining regulatory compliance in the public cloud. AlgoSec’s partnership with AWS helps organizations overcome these challenges by making the most of AWS’ capabilities and providing solutions that complement the AWS offering, particularly in terms of security and operational excellence. And to make things even easier, AlgoSec is now available in AWS Marketplace. Accelerating complex application migration with AlgoSec Many organizations choose to migrate workloads to AWS because it provides unparalleled opportunities for scalability, flexibility, and the ability to spin-up new servers within a few minutes. However, moving to AWS while still maintaining high-level security and avoiding application outages can be challenging, especially if you are trying to do the migration manually, which can create opportunities for human error. We help simplify the migration to AWS with a six-step automated process, which takes away manual processes and reduces the risk of error: Step 1 – AlgoSec automatically discovers and maps network flows to the relevant business applications. Step 2- AlgoSec assesses the changes in the application connectivity required to migrate it to AWS. Step 3- AlgoSec analyzes, simulates and computes the necessary changes, across the entire hybrid network (over firewalls, routers, security groups etc.), including providing a what-if risk analysis and compliance report. Step 4- AlgoSec automatically migrates the connectivity flows to the new AWS environment. Step 5 – AlgoSec securely decommissions old connectivity. Step 6- The AlgoSec platform provides ongoing monitoring and visibility of the cloud estate to maintain security and operation of policy configurations or successful continuous operation of the application. Gain control of hybrid estates with AlgoSec Security automation is essential if organizations are to maintain security and compliance across their hybrid environments, as well as get the full benefit of AWS agility and scalability. AlgoSec allows organizations to seamlessly manage security control layers across the entire network from on-premise to cloud services by providing Zero-Touch automation in three key areas. First, visibility is important, since understanding the network we have in the cloud helps us to understand how to deploy and manage the policies across the security controls that make up the hybrid cloud estate. We provide instant visibility, risk assessment and compliance, as well as rule clean-up, under one unified umbrella. Organizations can gain instant network visibility and maintain a risk-free optimized rule set across the entire hybrid network – across all AWS accounts, regions and VPC combinations, as well as 3rd party firewalls deployed in the cloud and across the connection to the on-prem network. Secondly, changes to network security policies in all these diverse security controls can be managed from a single system, security policies can be applied consistently, efficiently, and with a full audit trail of every change. Finally, security automation dramatically accelerates change processes and enables better enforcement and auditing for regulatory compliance. It also helps organizations overcome skill gaps and staffing limitations. Why Purchase Through AWS Marketplace?

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.

Firewall Change Management Firewall migration tips & best practices Joanne Godfrey 2 min read Joanne Godfrey 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. firewallmigration Tags Share this article 8/18/14 Published It goes without saying that security is the cornerstone of any organization today. This includes ensuring access to corporate data is secured, connectivity to the data center from both internal and external users is secured, and that critical security updates are installed. Now comes the big question: what if you have to migrate your security policy to a new platform? With cloud computing and distributed data centers across the world nothing in technology is ever constant anymore. So how do you control and manage a firewall migration? What if you use multiple vendors’ solutions with both virtual and physical appliances? A firewall migration can be as simple as moving from one model to another, or a lot more complicated. As an experienced cloud architect, I’ve been a part of a number of firewall migration projects. Here are three tips to help make your firewall migration project a little bit easier. Create powerful firewall and security visibility map. All aspects of your firewall must be documented and well planned before doing a migration, and you must plan for both current as well as future needs. Start by gathering information: create a visual, dynamic map of your firewall architecture and traffic, which should include all technical connectivity data. Understand, document and prepare policy migration. Once you have your visual firewall map it’s time to look under the hood. One firewall might be easy, but is it ever really just one security appliance? The dynamic nature of the modern data center means that multiple security vendors can live under one roof. So how do you create a policy migration plan around heterogeneous platforms? You need to identify and document all the security policies and services and network algorithms for each firewall end-point. Analyze business impact and create a migration path. How do your applications interact with various security policies? Do you have specific business units relying on specific firewall traffic? How are various data centers being segmented by your security policies? Migrating a firewall will have a business-wide impact. You must ensure that this impact is absolutely minimal. You need to understand how your entire business model interacts with firewall and security technologies and if any piece of the business is forgotten technological headaches may be the least of your worries. Migrating a firewall doesn’t have to be hard, but it must be well planned. With so much information traversing the modern data center, it’s imperative to have complete visibility across the security architecture. Ultimately, with the right tools to help you plan, map and actually implement a firewall change process, and lots of cups of coffee, you can greatly reduce security migration complexity. #FirewallMigration Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Network Security Policy Management Network segmentation vs. VLAN explained 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 Safeguarding the network architecture is the need of the hour. According to a study, the average cost of a data breach is at an all-time high of $4.35 million. And this figure will only increase with governments and regulators becoming ever stricter on data breaches. The go-to method IT administrators adopt to safeguard their networks is network segmentation. By segmenting a larger network into smaller chunks, it becomes much more manageable to secure the entire network. But network segmentation is a broad concept and doesn’t refer to a single procedure. In fact, there are several segmentation processes — one of them being VLAN. Instead of simplifying, this adds to the complexity. In this article, we will explain the core difference between network segmentation and VLAN and when you should opt for a particular one over the other. What is network segmentation? Let’s start with the definitions of network segmentation and VLAN. By definition, network segmentation is the practice of compartmentalizing a network according to firewall rules . In other words, it’s about dividing a computer network into subnetworks. The subnetworks, at the IP level, are known as subnets. Each of the subnets then works independently and in isolation. Think of how a nation is split into various states and provinces for better management at the local level. Running an entire nation at the federal level is too much work. In addition to subnetting, there are other segmentation options like firewall segmentation and SDN (Software Defined Network) segmentation. But for this article’s sake, we will focus on subnets since those are the most common. What is VLAN? VLAN or Virtual LAN (Virtual Local Area Network) is also a type of network segmentation approach where the main physical network is divided into multiple smaller virtual networks. The division is done logically or virtually, not requiring buying additional physical resources. The same resource is divided using computer logic. There are several benefits to dividing the parts of the network, either using VLAN segmentation or subnet techniques. Some of them are: Broadcast domain isolation Both subnets and VLAN isolate broadcast domains. This way, broadcasting network traffic is contained in a single segment instead of being exposed to the entire network. This reduces the chance of network congestion during peak hours and unnecessary server overload, thereby maximizing efficiency. Enhanced security The isolation by subnets or VLAN enhances the IT network’s security policies. This is achieved through various factors that are at play. But primarily, the creation of subnetworks makes the flat network more secure. With multiple subnetworks, you can regulate the security parameters. Thus, those subnets containing critical data (like that of healthcare) can have enhanced cybersecurity measures more than others, making them harder to crack. So, from a security perspective, both subnets and VLAN are a must. Better network management With digitization and IT modernization, the IT infrastructure is growing. Concurrently, it’s getting harder to manage them. Microsegmentation is one way of managing the ever-growing infrastructure. By segmenting, you can deploy teams to each segment, thereby strengthening their management and accountability. With the implementation of SDN, you can even configure and automate the management of some of the subnetworks. Flexibility in scalability Many network administrators face network performance and scalability issues expanding resources. The issues are a mix of technical and economical. Network segmentation offers a solution to such issues. By segmenting the entire data center network, you can choose which segments to expand and control the resources granted to each segment. This also makes scalability more economical. While both offer scalability opportunities, VLAN offers superior functionality than subnets. Reduced scope of compliance Compliance is another area that IT execs need to work on. And network segmentation, either via subnets or VLAN, can help in this regard. By having subnets, you don’t have to audit your entire segmented network as required by regulators. Just audit the necessary subnets and submit the reports to the regulators for approval. This takes far less time and costs significantly less than auditing the entire network. Differences between network segmentation and VLAN By definition, network segmentation (subnetting) and VLAN sound pretty similar. After all, there’s a division of the main network into subnetworks or smaller networks. But besides the core similarities mentioned above, there are a few critical differences. Let’s dive into the differences between the two. The primary difference between the two subnets are layer 3 divisions, while VLANs are layer 2 divisions. As you may recall, networks are layer 1 (device), layer 2 (data link), layer 3 (IP, routers), and so on, up to layer 7 (application). TCP/IP is the newer framework with four layers only. So, when you divide a network at a data link, you need to adopt VLAN. With VLAN, several networks exist on the same physical network but may not be connected to the same fiber switch. In subnets, the division occurs at IP level. Thus, the independent subnets are assigned their IP addresses and communicate with others over layer 3. Besides this significant difference, there are other dissimilarities you should know. Here’s a table to help you understand: VLAN Subnet 1 Divides the network within the same physical network using logic. Divides the IP network into multiple IP networks 2 VLANs communicate with other devices within the same LAN The communication between the subnets is carried out over layer 3 3 It is configured at the switch side It is configured at IP level 4 VLAN divisions are software-based terminology since they’re divided logically. Subnets can be both hardware- of software-based 5 VLAN provides better network access and tend to be more stable Subnets offer limited control When to adopt a subnet? There are use cases when subnets are more suited, while there are cases when you’re better off with Virtual LANs. As per the definition, you need to adopt a subnet when dividing different networks at IP level. So, if you want to create multiple IP addresses for each partition, implement subnets. The subnets are essentially networks within a network with their own IP addresses. Thus, they divide the broadcast domain and improve speed and efficiency. Subnets are also the go-to segmentation method when you need to make the sub-networks available over layer 3 to the outside world. With appropriate access control lists, anyone with an internet connection would be able to access the subnets But subnetting is also used to prevent access to a particular subnet. For example, you may want to limit access to the company’s software codebase to anyone outside the development department. So, only network devices with approved IP addresses used by the developer network are approved to access the codebase. But there are two downsides to subnets you should know. The first one is increased time complexity. When dealing with a single network, three steps are in place to reach the Process (Source Host, Destination Network, and Process). In subnets, there’s an additional step involved (Source Host, Destination Network, Subnet, Process). This extra step increases time complexity, requiring more time for data transfer and connectivity. It also affects stability. Subnetting also increases the number of IP addresses required since each subnet requires its own IP address. This can become hard to manage over time. When to adopt VLAN? Virtual LANs are internal networks within the same physical network. They interact with one another, not with other devices on the same network or outside the world. Think of VLAN as a private wireless network at home. Your neighbors don’t have access to it, but everyone in your home has. If that sounds like your desired result, you should adopt VLAN. There are three types of VLANs (basic, extended, and tagged). In basic VLAN, you assign IDs to each switch port or PCI . Once assigned, you can’t change them. Extended VLAN has more functionalities like priority-based routing. Lastly, tagged VLAN enables you to create multiple VLANs with IEEE 802.1Q. The main advantages of different VLANs over subnet are speed and stability. Since endpoints do not have to resolve IP addresses every time, they tend to be faster. But there’s a significant disadvantage to VLANs: It’s easier to breach multiple partitions if there’s a malicious injection. Without proper network security controls, it is easier to exploit vulnerabilities using malware and ransomware , putting your entire network at risk. Having ACLs (access control lists) can help in such situations. Furthermore, there are issues arising out of physical store requirements. Connecting two segments in VLAN requires you to use routers and IoT. Routers are physical devices that take up space. The more segments you create, the more routers you need to use. Over time, management can become an issue. The bottom line Both subnets and VLANs are network segmentation approaches that improve security and workload management. It’s not a given that you can’t have both. Some companies benefit from the implementation of VLAN and subnets simultaneously. But there are specific times when IT service providers prefer one over the other. Consider your requirements to select the approach that’s right for you.
