- Micro-segmentation from strategy to execution | AlgoSec
Implement micro-segmentation effectively, from strategy to execution, to enhance security, minimize risks, and protect critical assets across your network. Micro-segmentation from strategy to execution Overview Learn how to plan and execute your micro-segmentation project in AlgoSec’s guide. Schedule a Demo What is Micro segmentation Micro-segmentation is a technique to create secure zones in networks. It lets companies isolate workloads from one another and introduce tight controls over internal access to sensitive data. This makes network security more granular. Micro-segmentation is an “upgrade” to network segmentation. Companies have long relied on firewalls, VLANs, and access control lists (ACL) to segment their network. Network segmentation is a key defense-in-depth strategy, segregating and protecting company data and limiting attackers’ lateral movements. Consider a physical intruder who enters a gated community. Despite having breached the gate, the intruder cannot freely enter the houses in the community because, in addition to the outside gate, each house has locks on its door. Micro-segmentation takes this an additional step further – even if the intruder breaks into a house, the intruder cannot access all the rooms. Schedule a Demo Why Micro-segment? Organizations frequently implement micro-segmentation to block lateral movement. Two common types of lateral movements are insider threats and ransomware. Insider threats are employees or contractors gaining access to data that they are not authorized to access. Ransomware is a type of malware attack in which the attacker locks and encrypts the victim’s data and then demands a payment to unlock and decrypt the data. If an attacker takes over one desktop or one server in your estate and deploys malware, you want to reduce the “blast radius” and make sure that the malware can’t spread throughout the entire data center. And if you decide not to pay the ransom? Datto’s Global State of the Channel Ransomware Report informs us that: The cost of downtime is 23x greater than the average ransom requested in 2019. Downtime costs due to ransomware are up by 200% year-over-year. Schedule a Demo The SDN Solution With software-defined networks, such as Cisco ACI and VMware NSX, micro-segmentation can be achieved without deploying additional controls such as firewalls. Because the data center is software-driven, the fabric has built-in filtering capabilities. This means that you can introduce policy rules without adding new hardware. SDN solutions can filter flows both inside the data center (east-west traffic) and flows entering or exiting the data center (north-south traffic). The SDN technology supporting your data center eliminates many of the earlier barriers to micro-segmentation. Yet, although a software-defined fabric makes segmentation possible, there are still many challenges to making it a reality. Schedule a Demo What is a Good Filtering Policy A good filtering policy has three requirements: 1 – Allows all business traffic The last thing you want is to write a micro-segmented policy and have it break necessary business communication, causing applications to stop functioning. 2 – Allows nothing else By default, all other traffic should be denied. 3 – Future-proof “More of the same” changes in the network environment shouldn’t break rules. If you write your policies too narrowly, then any change in the network, such as a new server or application, could cause something to stop working. Write with scalability in mind. How do organizations achieve these requirements? They need to know what the traffic flows are as well as what should be allowed and what should be denied. This is difficult because most traffic is undocumented. There is no clear record of the applications in the data center and what network flows they depend on. To get accurate information, you need to perform a “discovery” process. Schedule a Demo A Blueprint for Creating a Micro-segmentation Policy Micro-segmentation Blueprint Discovery You need to find out which traffic needs to be allowed and then you can decide what not to allow. Two common ways to implement a discovery process are traffic-based discovery and content-based discovery. Traffic-Based Discovery Traffic-based discovery is the process of understanding traffic flows: Observe the traffic that is traversing the data center, analyze it, and identify the intent of the flows by mapping them to the applications they support. You can collect the raw traffic with a traffic sniffer/network TAP or use a NetFlow feed. Content-based or Data-Based Approach In the content-based approach, you organize the data center systems into segments based on the sensitivity of the data they process. For example, an eCommerce application may process credit card information which is regulated by the PCI DSS standard. Therefore, you need to identify the servers supporting the eCommerce application and separate them in your filtering policy. Discovering traffic flows within a data center Micro-segmentation Blueprint Using NetFlow for Traffic Mapping The traffic source on which it is easiest to base application discovery is NetFlow. Most routers and switches can be configured to emit a NetFlow feed without requiring the deployment of agents throughout the data center. The flows in the NetFlow feed are clustered into business applications based on recurring IP addresses and correlations in time. For example, if an HTTPS connection from a client at 172.7.1.11 to 10.3.3.3 is observed at 10 AM, and a PostgreSQL connection from the same 10.3.3.3 to 10.1.1.1 is observed 0.5 seconds later, it’s clear that all three systems support a single application, which can be labeled with a name such as “Trading System”. 172.7.1.0/2410.3.3.3 TRADE SYS HTTPS10.3.3.3 TRADE SYS 10.1.1.11 DB TCP/543210.3.3.7 FOREX 10.1.1.11 DB TCP/5432 Identifying traffic flows in common, based on shared IP addresses NetFlow often produces thousands of “thin flow” records (one IP to another IP), even for a single application. In the example above, there may be a NetFlow record for every client desktop. It is important to aggregate them into “fat flows” (e.g., that allows all the clients in the 172.7.1.0/24 range). In addition to avoiding an explosion in the number of flows, aggregation also provides a higher-level understanding, as well as future-proofing the policies against fluctuations in IP address allocation. Using the discovery platform in the AlgoSec Security Management Suite to identify the flows in combination with information from your firewalls can help you decide where to put the boundaries of your segments and which policies to put in these filters. Micro-segmentation Blueprint Defining Logical Segments Once you have discovered the business applications whose traffic is traversing the data center (using traffic-based discovery) and have also identified the data sensitivity (using a content-based approach) you are well positioned to define your segments. Bear in mind that all the traffic that is confined to a segment is allowed. Traffic crossing between segments is blocked by default – and needs to be explicitly allowed by a policy rule. There are two potential starting points: Segregate the systems processing sensitive data into their own segments. You may have to do this anyway for regulatory reasons. Segregate networks connecting to client systems (desktops, laptops, wireless networks) into “human-zone” segments. Client systems are often the entry points of malware, and are always the source of malicious insider attacks. Then, place the remaining servers supporting each application, each in its own segment. Doing so will save you the need to write explicit policy rules to allow traffic that is internal to only one business application. Example segment within a data center Micro-segmentation Blueprint Creating the Filtering Policy Once the segments are defined, we need to write the policy. Traffic confined to a segment is automatically allowed so we don’t need to worry about it anymore. We just need to write policy for traffic crossing micro-segment boundaries. Eventually, the last rule on the policy must be a default-deny: “from anywhere to anywhere, with any service – DENY.” However, enforcing such a rule in the early days of the micro-segmentation project, before all the rest of the policy is written, risks breaking many applications’ communications. So start with a (totally insecure) default-allow rule until your policy is ready, and then switch to a default-deny on “D-Day” (“deny-day”). We’ll discuss D-Day shortly. What types of rules are we going to be writing? Cross segment flows – Allowing traffic between segments: e.g., Allow the eCommerce servers to access the credit-card Flows to/from outside the data center – e.g., allow employees in the finance department to connect to financial data within the data center from their machines in the human-zone, or allow access from the Internet to the front-end eCommerce web servers. Users outside the data center need to access data within the data center Micro-segmentation Blueprint Default Allow – with Logging To avoid major connectivity disruptions, start your micro-segmentation project gently. Instead of writing a “DENY” rule at the end of the policy, write an “ALLOW” rule – which is clearly insecure – but turn on logging for this ALLOW rule. This creates a log of all connections that match the default-allow rule. Initially you will receive many logs entries from the default-allow rule; your goal in the project is to eliminate them. To do this, you go over the applications you discovered earlier, write the policy rules that support each application’s cross-segment flows, and place them above the default-allow rule. This means that the traffic of each application you handle will no longer match the default-allow (it will match the new rules you wrote) – and the amount of default-allow logs will decrease. Keep adding rules, application by application, until the final allow rule is not generating any more logs. At that point, you reach the final milestone in the project: D-Day. Micro-segmentation Blueprint Preparing for “D-Day” Once logging generated by the default-allow rule ceases to indicate new flows that need to be added to your filtering policy, you can start preparing for “D-Day.” This is the day that you flip the switch and change the final rule from “default ALLOW” to “default DENY.” Once you do that, all the undiscovered traffic is going to be denied by the filtering fabric, and you will finally have a secured, micro-segmented, data center. This is a big deal! However, you should realize that D-Day is going to cause a big organizational change. From this day forward, every application developer whose application requires new traffic to cross the data center will need to ask for permission to allow this traffic; they will need to follow a process, which includes opening a change request, and then wait for the change to be implemented. The free-wheeling days are over. You need to prepare for D-Day. Consider steps such as: Get management buy-in Communicate the change across the organization Set a change control window Have “all hands on deck” on D-Day to quickly correct anything that may have been missed and causes applications to break Micro-segmentation Blueprint Change Requests & Compliance Notice that after D-Day, any change in application connectivity requires filing a “change request”. When the information security team is evaluating a change request – they need to check whether the request is in line with the “acceptable traffic” policy. A common method for managing policy at the high-level is to use a table, where each row represents a segment, and every column represents a segment. Each cell in the table lists all the services that are allowed from its “row” segment to its “column” segment. Keeping this table in a machine readable format, such an Excel spreadsheet, enables software systems to run a what-if risk-check that compares each change-request with the acceptable policy, and flags any discrepancies before the new rules are deployed. Such a what-if risk-check is also important for regulatory compliance. Regulations such as PCI and ISO27001 require organizations to define such a policy, and to compare themselves to it; demonstrating the policy is often part of the certification or audit.

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 2025 in review: What innovations and milestones defined AlgoSec’s transformative year in 2025?

Risk Management and Vulnerabilities How to optimize the security policy management lifecycle Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published Information security is vital to business continuity. Organizations trust their IT teams to enable innovation and business transformation but need them to safeguard digital assets in the process. This leads some leaders to feel that their information security policies are standing in the way of innovation and business agility. Instead of rolling new a new enterprise application and provisioning it for full connectivity from the start, security teams demand weeks or months of time to secure those systems before they’re ready. But this doesn’t mean that cybersecurity is a bottleneck to business agility. The need for speedier deployment doesn’t automatically translate to increased risk. Organizations that manage application connectivity and network security policies using a structured lifecycle approach can improve security without compromising deployment speed. Many challenges stand between organizations and their application and network connectivity goals. Understanding each stage of the lifecycle approach to security policy change management is key to overcoming these obstacles. Challenges to optimizing security policy management ` Complex enterprise infrastructure and compliance requirements A medium-sizded enterprise may have hundreds of servers, systems, and security solutions like firewalls in place. These may be spread across several different cloud providers, with additional inputs from SaaS vendors and other third-party partners. Add in strict regulatory compliance requirements like HIPAA , and the risk management picture gets much more complicated. Even voluntary frameworks like NIST heavily impact an organization’s information security posture, acceptable use policies, and more – without the added risk of non-compliance. Before organizations can optimize their approach to security policy management, they must have visibility and control over an increasingly complex landscape. Without this, making meaningful progress of data classification and retention policies is difficult, if not impossible. Modern workflows involve non-stop change When information technology teams deploy or modify an application, it’s in response to an identified business need. When those deployments get delayed, there is a real business impact. IT departments now need to implement security measures earlier, faster, and more comprehensively than they used to. They must conduct risk assessments and security training processes within ever-smaller timeframes, or risk exposing the organization to vulnerabilities and security breaches . Strong security policies need thousands of custom rules There is no one-size-fits-all solution for managing access control and data protection at the application level. Different organizations have different security postures and security risk profiles. Compliance requirements can change, leading to new security requirements that demand implementation. Enterprise organizations that handle sensitive data and adhere to strict compliance rules must severely restrict access to information systems. It’s not easy to achieve PCI DSS compliance or adhere to GDPR security standards solely through automation – at least, not without a dedicated change management platform like AlgoSec . Effectively managing an enormous volume of custom security rules and authentication policies requires access to scalable security resources under a centralized, well-managed security program. Organizations must ensure their security teams are equipped to enforce data security policies successfully. Inter-department communication needs improvement Application deliver managers, network architects, security professionals, and compliance managers must all contribute to the delivery of new application projects. Achieving clear channels of communication between these different groups is no easy task. In most enterprise environments, these teams speak different technical languages. They draw their data from internally siloed sources, and rarely share comprehensive documentation with one another. In many cases, one or more of these groups are only brought in after everyone else has had their say, which significantly limits the amount of influence they can have. The lifecycle approach to managing IT security policies can help establish a standardized set of security controls that everyone follows. However, it also requires better communication and security awareness from stakeholders throughout the organization. The policy management lifecycle addresses these challenges in five stages ` Without a clear security policy management lifecycle in place, most enterprises end up managing security changes on an ad hoc basis. This puts them at a disadvantage, especially when security resources are stretched thin on incident response and disaster recovery initiatives. Instead of adopting a reactive approach that delays application releases and reduces productivity, organizations can leverage the lifecycle approach to security policy management to address vulnerabilities early in the application development lifecycle. This leaves additional resources available for responding to security incidents, managing security threats, and proactively preventing data breaches. Discover and visualize application connectivity The first stage of the security policy management lifecycle revolves around mapping how your apps connect to each other and to your network setup. The more details can include in this map, the better prepared your IT team will be for handling the challenges of policy management. Performing this discovery process manually can cost enterprise-level security teams a great deal of time and accuracy. There may be thousands of devices on the network, with a complex web of connections between them. Any errors that enter the framework at this stage will be amplified through the later stages – it’s important to get things right at this stage. Automated tools help IT staff improve the speed and accuracy of the discovery and visualization stage. This helps everyone – technical and nontechnical staff included – to understand what apps need to connect and work together properly. Automated tools help translate these needs into language that the rest of the organization can understand, reducing the risk of misconfiguration down the line. Plan and assess security policy changes Once you have a good understanding of how your apps connect with each other and your network setup, you can plan changes more effectively. You want to make sure these changes will allow the organization’s apps to connect with one another and work together without increasing security risks. It’s important to adopt a vulnerability-oriented perspective at this stage. You don’t want to accidentally introduce weak spots that hackers can exploit, or establish policies that are too complex for your organization’s employees to follow. This process usually involves translating application connectivity requests into network operations terms. Your IT team will have to check if the proposed changes are necessary, and predict what the results of implementing those changes might be. This is especially important for cloud-based apps that may change quickly and unpredictably. At the same time, security teams must evaluate the risks and determine whether the changes are compliant with security policy. Automating these tasks as part of a regular cycle ensures the data is always relevant and saves valuable time. Migrate and deploy changes efficiently The process of deploying new security rules is complex, time-consuming, and prone to error . It often stretches the capabilities of security teams that already have a wide range of operational security issues to address at any given time. In between managing incident response and regulatory compliance, they must now also manually update thousands of security rules over a fleet of complex network assets. This process gets a little bit easier when guided by a comprehensive security policy change management framework. But most organizations don’t unlock the true value of the security policy management lifecycle until they adopt automation. Automated security policy management platforms enable organizations to design rule changes intelligently, migrate rules automatically, and push new policies to firewalls through a zero-touch interface. They can even validate whether the intended changes updated correctly. This final step is especially important. Without it, security teams must manually verify whether their new policies successfully address the vulnerabilities the way they’re supposed to. This doesn’t always happen, leaving security teams with a false sense of security. Maintain configurations using templates Most firewalls accumulate thousands of rules as security teams update them against new threats. Many of these rules become outdated and obsolete over time, but remain in place nonetheless. This adds a great deal of complexity to small-scale tasks like change management, troubleshooting issues, and compliance auditing. It can also impact the performance of firewall hardware , which decreases the overall lifespan of expensive physical equipment. Configuration changes and maintenance should include processes for identifying and eliminating rules that are redundant, misconfigured, or obsolete. The cleaner and better-documented the organization’s rulesets are, the easier subsequent configuration changes will be. Rule templates provide a simple solution to this problem. Organizations that create and maintain comprehensive templates for their current firewall rulesets can easily modify, update, and change those rules without having to painstakingly review and update individual devices manually. Decommission obsolete applications completely Every business application will eventually reach the end of its lifecycle. However, many organizations keep decommissioned security policies in place for one of two reasons: Oversight that stems from unstandardized or poorly documented processes, or; Fear that removing policies will negatively impact other, active applications. As these obsolete security policies pile up, they force the organization to spend more time and resources updating their firewall rulesets. This adds bloat to firewall security processes, and increases the risk of misconfigurations that can lead to cyber attacks. A standardized, lifecycle-centric approach to security policy management makes space for the structured decommissioning of obsolete applications and the rules that apply to them. This improves change management and ensures the organization’s security posture is optimally suited for later changes. At the same time, it provides comprehensive visibility that reduces oversight risks and gives security teams fewer unknowns to fear when decommissioning obsolete applications. Many organizations believe that Security stands in the way of the business – particularly when it comes to changing or provisioning connectivity for applications. It can take weeks, or even months to ensure that all the servers, devices, and network segments that support the application can communicate with each other while blocking access to hackers and unauthorized users. It’s a complex and intricate process. This is because, for every single application update or change, Networking and Security teams need to understand how it will affect the information flows between the various firewalls and servers the application relies on, and then change connectivity rules and security policies to ensure that only legitimate traffic is allowed, without creating security gaps or compliance violations. As a result, many enterprises manage security changes on an ad-hoc basis: they move quickly to address the immediate needs of high-profile applications or to resolve critical threats, but have little time left over to maintain network maps, document security policies, or analyze the impact of rule changes on applications. This reactive approach delays application releases, can cause outages and lost productivity, increases the risk of security breaches and puts the brakes on business agility. But it doesn’t have to be this way. Nor is it necessary for businesses to accept greater security risk to satisfy the demand for speed. Accelerating agility without sacrificing security The solution is to manage application connectivity and network security policies through a structured lifecycle methodology, which ensures that the right security policy management activities are performed in the right order, through an automated, repeatable process. This dramatically speeds up application connectivity provisioning and improves business agility, without sacrificing security and compliance. So, what is the network security policy management lifecycle, and how should network and security teams implement a lifecycle approach in their organizations? Discover and visualize The first stage involves creating an accurate, real-time map of application connectivity and the network topology across the entire organization, including on-premise, cloud, and software-defined environments. Without this information, IT staff are essentially working blind, and will inevitably make mistakes and encounter problems down the line. Security policy management solutions can automate the application connectivity discovery, mapping, and documentation processes across the thousands of devices on networks – a task that is enormously time-consuming and labor-intensive if done manually. In addition, the mapping process can help business and technical groups develop a shared understanding of application connectivity requirements. Plan and assess Once there is a clear picture of application connectivity and the network infrastructure, you can start to plan changes more effectively – ensure that proposed changes will provide the required connectivity, while minimizing the risks of introducing vulnerabilities, causing application outages, or compliance violations. Typically, it involves translating application connectivity requests into networking terminology, analyzing the network topology to determine if the changes are really needed, conducting an impact analysis of proposed rule changes (particularly valuable with unpredictable cloud-based applications), performing a risk and compliance assessment, and assessing inputs from vulnerabilities scanners and SIEM solutions. Automating these activities as part of a structured lifecycle keeps data up-to-date, saves time, and ensures that these critical steps are not omitted – helping avoid configuration errors and outages. Functions Of An Automatic Pool Cleaner An automatic pool cleaner is very useful for people who have a bad back and find it hard to manually operate the pool cleaner throughout the pool area. This type of pool cleaner can move along the various areas of a pool automatically. Its main function is to suck up dirt and other debris in the pool. It functions as a vacuum. Automatic pool cleaners may also come in different types and styles. These include automatic pressure-driven cleaners, automatic suction side-drive cleaners, and robotic pool cleaners. Migrate and deploy Deploying connectivity and security rules can be a labor-intensive and error-prone process. Security policy management solutions automate the critical tasks involved, including designing rule changes intelligently, automatically migrating rules, and pushing policies to firewalls and other security devices – all with zero-touch if no problems or exceptions are detected. Crucially, the solution can also validate that the intended changes have been implemented correctly. This last step is often neglected, creating the false impression that application connectivity has been provided, or that vulnerabilities have been removed, when in fact there are time bombs ticking in the network. Maintain Most firewalls accumulate thousands of rules which become outdated or obsolete over the years. Bloated rulesets not only add complexity to daily tasks such as change management, troubleshooting and auditing, but they can also impact the performance of firewall appliances, resulting in decreased hardware lifespan and increased TCO. Cleaning up and optimizing security policies on an ongoing basis can prevent these problems. This includes identifying and eliminating or consolidating redundant and conflicting rules; tightening overly permissive rules; reordering rules; and recertifying expired ones. A clean, well-documented set of security rules helps to prevent business application outages, compliance violations, and security gaps and reduces management time and effort. Decommission Every business application eventually reaches the end of its life: but when they are decommissioned, its security policies are often left in place, either by oversight or from fear that removing policies could negatively affect active business applications. These obsolete or redundant security policies increase the enterprise’s attack surface and add bloat to the firewall ruleset. The lifecycle approach reduces these risks. It provides a structured and automated process for identifying and safely removing redundant rules as soon as applications are decommissioned while verifying that their removal will not impact active applications or create compliance violations. We recently published a white paper that explains the five stages of the security policy management lifecycle in detail. It’s a great primer for any organization looking to move away from a reactive, fire-fighting response to security challenges, to an approach that addresses the challenges of balancing security and risk with business agility.

Tags Share this article 8/19/21 Published Kyle Wickert explains how organizations can balance the need to modernize their networks without compromising security For businesses of all shapes and sizes, the inherent value in moving enterprise applications into the cloud is beyond question. The ability to control computing capability at a more granular level can lead to significant cost savings, not to mention the speed at which new applications can be provisioned. Having a modern cloud-based infrastructure makes businesses more agile, allowing them to capitalize on market forces and other new opportunities much quicker than if they depended on on-premises, monolithic architecture alone. However, there is a very real risk that during the goldrush to modernized infrastructures, particularly during the pandemic when the pressure to migrate was accelerated rapidly, businesses might be overlooking the potential blind spot that threatens all businesses indiscriminately, and that is security. One of the biggest challenges for business leaders over the past decade has been managing the delicate balance between infrastructure upgrades and security. Our recent survey found that half of organizations who took part now run over 41% of workloads in the public cloud, and 11% reported a cloud security incident in the last twelve months. If businesses are to succeed and thrive in 2021 and beyond, they must learn how to walk this tightrope effectively. Let’s consider the highs and lows of modernizing legacy infrastructures, and the ways to make it a more productive experience. What are the risks in moving to the cloud? With cloud migration comes risk. Businesses that move into the cloud actually stand to lose a great deal if the process isn’t managed effectively. Moreover, they have some important decisions to make in terms of how they handle application migration. Do they simply move their applications and data into the cloud as they are as a ‘lift and shift’, or do they seek to take a more cloud-native approach and rebuild applications in the cloud to take full advantage of its myriad benefits? Once a business has started this move toward the cloud, it’s very difficult to rewind the process and unpick mistakes that may have been made, so planning really is critical. Then there’s the issue of attack surface area. Legacy on-premises applications might not be the leanest or most efficient, but they are relatively secure by default due to their limited exposure to external environments. Moving said applications onto the cloud has countless benefits to agility, efficiency, and cost, but it also increases the attack surface area for potential hackers. In other words, it gives bots and bad actors a larger target to hit. One of the many traps that businesses fall into is thinking that just because an application is in the cloud, it must be automatically secure. In fact, the reverse is true unless proper due diligence is paid to security during the migration process. The benefits of an app-centric approach One of the ways in which AlgoSec helps its customer master security in the cloud is by approaching it from an app-centric perspective. By understanding how a business uses its applications, including its connectivity paths through the cloud, data centers and SDN fabrics, we can build an application model that generates actionable insights such as the ability to create policy-based risks instead of leaning squarely on firewall controls. This is of particular importance when moving legacy applications onto the cloud. The inherent challenge here is that a business is typically taking a vulnerable application and making it even more vulnerable by moving it off-premise, relying solely on the cloud infrastructure to secure it. To address this, businesses should rank applications in order of sensitivity and vulnerability. In doing so, they may find some quick wins in terms of moving modern applications into the cloud that have less sensitive data. Once these short-term gains are dealt with, NetSecOps can focus on the legacy applications that contain more sensitive data which may require more diligence, time, and focus to move or rebuild securely. Migrating applications to the cloud is no easy feat and it can be a complex process even for the most technically minded NetSecOps. Automation takes a large proportion of the hard work away and enables teams to manage cloud environments efficiently while orchestrating changes across an array of security controls. It brings speed and accuracy to managing security changes and accelerates audit preparation for continuous compliance. Automation also helps organizations overcome skills gaps and staffing limitations. We are likely to see conflict between modernization and security for some time. On one hand, we want to remove the constraints of on-premises infrastructure as quickly as possible to leverage the endless possibilities of cloud. On the other hand, we have to safeguard against the opportunistic hackers waiting on the fray for the perfect time to strike. By following the guidelines set out in front of them, businesses can modernize without compromise.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/2/23 Published Cloud threats are at an all-time high. But not only that, hackers are becoming more sophisticated with cutting-edge tools and new ways to attack your systems. Cloud service providers can only do so much. So, most of the responsibility for securing your data and applications will still fall on you. This makes it critical to equip your organization’s cloud architects and security teams with the necessary skills that help them stay ahead of the evolving threat landscape. Although the core qualities of a cloud architect remain the same, upskilling requires them to learn emerging skills in strategy, leadership, operational, and technical areas. Doing this makes your cloud architects and security teams well-rounded to solve complex cloud issues and ensure the successful design of cloud security architecture. Here, we’ll outline the top skills for cloud architects. This can be a guide for upskilling your current security team and hiring new cloud security architects. But besides the emerging skills, what are the core responsibilities of a cloud security architect? Responsibilities of Cloud Security Architects A cloud security architect builds, designs, and deploys security systems and controls for cloud-based computing services and data storage systems. Their responsibilities will likely depend on your organization’s cloud security strategy. Here are some of them: 1. Plan and Manage the Organization’s Cloud Security Architecture and Strategy: Security architects must work with other security team members and employees to ensure the security architecture aligns with your organization’s strategic goals. 2. Select Appropriate Security Tools and Controls: Cloud security architects must understand the capabilities and limitations of cloud security tools and controls and contribute when selecting the appropriate ones. This includes existing enterprise tools with extensibility to cloud environments, cloud-native security controls, and third-party services. They are responsible for designing new security protocols whenever needed and testing them to ensure they work as expected. 3. Determine Areas of Deployments for Security Controls: After selecting the right tools, controls, and measures, architects must also determine where they should be deployed within the cloud security architecture. 4. Participating in Forensic Investigations: Security architects may also participate in digital forensics and incident response during and after events. These investigations can help determine how future incidents can be prevented. 5. Define Design Principles that Govern Cloud Security Decisions: Cloud security architects will outline design principles that will be used to make choices on the security tools and controls to be deployed, where, and from which sources or vendors. 6. Educating employees on data security best practices: Untrained employees can undo the efforts of cloud security architects. So, security architects must educate technical and non-technical employees on the importance of data security. This includes best practices for creating strong passwords, identifying social engineering attacks, and protecting sensitive information. Best Practices for Prioritizing Cloud Security Architecture Skills Like many other organizations, there’s a good chance your company has moved (or is in the process of moving) all or part of its resources to the cloud. This could either be a cloud-first or cloud-only strategy. As such, they must implement strong security measures that protect the enterprise from emerging threats and intrusions. Cloud security architecture is only one of many aspects of cloud security disciplines. And professionals specializing in this field must advance their skillset to make proper selections for security technologies, procedures, and the entire architecture. However, your cloud security architects cannot learn everything. So, you must prioritize and determine the skills that will help them become better architects and deliver effective security architectures for your organization. To do this, you may want to consider the demand and usage of the skill in your organization. Will upskilling them with these skills solve any key challenge or pain point in your organization? You can achieve this by identifying the native security tools key to business requirements, compliance adherence, and how cloud risks can be managed effectively. Additionally, you should consider the relevance of the skill to the current cloud security ecosystem. Can they apply this skill immediately? Does it make them better cloud security architects? Lastly, different cloud deployment (e.g., a public, private, edge, and distributed cloud) or cloud service models (e.g., Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS)) bring unique challenges that demand different skillsets. So, you must identify the necessary skills peculiar to each proposed project. Once you have all these figured out, here are some must-have skillsets for cloud security architects. Critical Skills for Cloud Security Architect Cloud security architects need several common skills, like knowledge of programming languages (.NET, PHP, Python, Java, Ruby, etc.), network integration with cloud services, and operating systems (Windows, macOS, and Linux). However, due to the evolving nature of cloud threats, more skills are required. Training your security teams and architects can have more advantages than onboarding new recruits. This is because existing teams are already familiar with your organization’s processes, culture, and values. However, whether you’re hiring new cloud security architects or upskilling your current workforce, here are the most valuable skills to look out for or learn. 1. Experience in cloud deployment models (IaaS, PaaS, and SaaS) It’s important to have cloud architects and security teams that integrate various security components in different cloud deployments for optimal results. They must understand the appropriate security capabilities and patterns for each deployment. This includes adapting to unique security requirements during deployment, combining cloud-native and third-party tools, and understanding the shared responsibility model between the CSP and your organization. 2. Knowledge of cloud security frameworks and standards Cloud security frameworks, standards, and methodologies provide a structured approach to security activities. Interpreting and applying these frameworks and standards is a critical skill for security architects. Some cloud security frameworks and standards include ISO 27001, ISAE 3402, CSA STAR, and CIS benchmarks. Familiarity with regional or industry-specific requirements like HIPAA, CCPA, and PCI DSS can ensure compliance with regulatory requirements. Best practices like the AWS Well-Architected Framework, Microsoft Cloud Security Benchmark, and Microsoft Cybersecurity Reference Architectures are also necessary skills. 3. Understanding of Native Cloud Security Tools and Where to Apply Them Although most CSPs have native tools that streamline your cloud security policies, understanding which tools your organization needs and where is a must-have skill. There are a few reasons why; it’s cost-effective, integrates seamlessly with the respective cloud platform, enhances management and configuration, and aligns with the CSP’s security updates. Still, not all native tools are necessary for your cloud architecture. As native security tools evolve, cloud architects must constantly be ahead by understanding their capabilities. 4. Knowledge of Cloud Identity and Access Management (IAM) Patterns IAM is essential for managing user access and permissions within the cloud environment. Familiarity with IAM patterns ensures proper security controls are in place. Note that popular cloud service providers, like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, may have different processes for implementing IAM. However, the key principles of IAM policies remain. So, your cloud architects must understand how to define appropriate IAM measures for access controls, user identities, authentication techniques like multi-factor authentication (MFA) or single sign-on (SSO), and limiting data exfiltration risks in SaaS apps. 5. Proficiency with Cloud-Native Application Protection Platforms CNAPP is a cloud-native security model that combines the capabilities of Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), and Cloud Service Network Security (CSNS) into a single platform. Cloud solutions like this simplify monitoring, detecting, and mitigating cloud security threats and vulnerabilities. As the nature of threats advances, using CNAPPs like Prevasio can provide comprehensive visibility and security of your cloud assets like Virtual Machines, containers, object storage, etc. CNAPPs enable cloud security architects to enhance risk prioritization by providing valuable insights into Kubernetes stack security configuration through improved assessments. 6. Aligning Your Cloud Security Architecture with Business Requirements It’s necessary to align your cloud security architecture with your business’s strategic goals. Every organization has unique requirements, and your risk tolerance levels will differ. When security architects are equipped to understand how to bridge security architecture and business requirements, they can ensure all security measures and control are calibrated to mitigate risks. This allows you to prioritize security controls, ensures optimal resource allocation, and improves compliance with industry-specific regulatory requirements. 7. Experience with Legacy Information Systems Although cloud adoption is increasing, many organizations have still not moved all their assets to the cloud. At some point, some of your on-premises legacy systems may need to be hosted in a cloud environment. However, legacy information systems’ architecture, technologies, and security mechanisms differ from modern cloud environments. This makes it important to have cloud security architects with experience working with legacy information systems. Their knowledge will help your organization solve any integration challenges when moving to the cloud. It will also help you avoid security vulnerabilities associated with legacy systems and ensure continuity and interoperability (such as data synchronization and maintaining data integrity) between these systems and cloud technologies. 8. Proficiency with Databases, Networks, and Database Management Systems (DBMS) Cloud security architects must also understand how databases and database management systems (DBMS) work. This knowledge allows them to design and implement the right measures that protect data stored within the cloud infrastructure. Proficiency with databases can also help them implement appropriate access controls and authentication measures for securing databases in the cloud. For example, they can enforce role-based access controls (RBAC) within the database environment. 9. Solid Understanding of Cloud DevOps DevOps is increasingly becoming more adopted than traditional software development processes. So, it’s necessary to help your cloud security architects embrace and support DevOps practices. This involves developing skills related to application and infrastructure delivery. They should familiarize themselves with tools that enable integration and automation throughout the software delivery lifecycle. Additionally, architects should understand agile development processes and actively work to ensure that security is seamlessly incorporated into the delivery process. Other crucial skills to consider include cloud risk management for enterprises, understanding business architecture, and approaches to container service security. Conclusion By upskilling your cloud security architects, you’re investing in their personal development and equipping them with skills to navigate the rapidly evolving cloud threat landscape. It allows them to stay ahead of emerging threats, align cloud security practices with your business requirements, and optimize cloud-native security tools.
