Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated. Think about it: your apps and data aren't neatly tucked away in one place anymore. They're bouncing around on AWS, Azure, GCP, all sorts of platforms – practically everywhere! Trying to handle that with old-school security is like trying to catch smoke with a fishing net. Not gonna work, right? That's why we're chatting today. Gal Yosef, Head of Product Management in the U.S., gets it. He's helped us dive into some crucial mindset shifts – basically, new ways of thinking – that are essential for navigating the craziness of modern security. We gotta ditch the old ways and get ready to be more agile, work together better, and ultimately, be way more effective. Mindset Shift #1: From "Our Stuff is Safe Inside This Box" to "Trust Nothing, Verify Everything" Remember the good old days? We built a perimeter – firewalls, VPNs – thinking that everything inside was safe and sound (danger!). Security was all about guarding that edge. The Problem: Well, guess what? That world is gone! Multi-cloud environments have totally shattered that perimeter. Trying to just secure the network edge leaves your real treasures – your applications, users, and data – vulnerable as they roam across different clouds. It's like locking the front door but leaving all the windows wide open! The New Way: Distributed Trust. Security needs to follow your assets, wherever they go. Instead of just focusing on the infrastructure (the pipes and wires), we need to embrace Zero-Trust principles . Think of it like this: never assume anyone or anything is trustworthy, even if they're "inside." We need identity-based, adaptive security policies that constantly validate trust, rather than just assuming it based on location. Security becomes built into applications and workloads, not just bolted onto the network. Think of it this way: Instead of one big, guarded gate, you have individual, smart locks on every valuable asset. You're constantly checking who's accessing what, no matter where they are. It's like having a personal bodyguard for each of your important things, always making sure they have the right ID. Mindset Shift #2: From "My Team Handles Network Security, Their Team Handles Cloud Security" to "Let's All Be Security Buddies!" Ever feel like your network security team speaks a different language than your cloud security team? You're not alone! Traditionally, these have been separate worlds, with network teams focused on firewalls and cloud teams on security groups. The Problem: These separate silos are a recipe for confusion and fragmented security policies. Attackers? They love this! It's like having cracks in your armor. They aren't always going to bash down the front door; they're often slipping through the gaps created by this lack of communication. The New Way: Cross-functional collaboration. We need to tear down those walls! Network and cloud security teams need to work together, speaking a shared security language. Unified visibility and consistent policies across all your environments are key. Think of it like a superhero team – everyone has their own skills, but they work together seamlessly to fight the bad guys. Regular communication, shared tools, and a common understanding of the risks are crucial. Mindset Shift #3: From "Reacting When Something Breaks" to "Always Watching and Fixing Things Before They Do" Remember the old days of waiting for an alert to pop up saying something was wrong? That's like waiting for your car to break down before you even think about checking the oil. Not the smartest move, right? The Problem: In the fast-paced world of the cloud, waiting for things to go wrong is a recipe for disaster. Attacks can happen super quickly, and by the time you react, the damage might already be done. Plus, manually checking everything all the time? Forget about it – it's just not scalable when you've got stuff spread across multiple clouds. The New Way: Continuous & Automated Enforcement. We need to shift to a mindset of constant monitoring and automated security actions. Think of it like having a security system that's always on, always learning, and can automatically respond to threats in real-time. This means using tools and processes that continuously check for vulnerabilities, enforce security policies automatically, and even predict potential problems before they happen. It's like having a proactive security guard who not only watches for trouble but can also automatically lock doors and sound alarms the moment something looks fishy. Mindset Shift #4: From "Locking Everything Down Tight" to "Finding the Right Balance with Flexible Rules" We used to think the best security was the strictest security – lock everything down, say "no" to everything. But let's be honest, that can make it super hard for people to actually do their jobs! It's like putting so many locks on a door that nobody can actually get through it. The Problem: Overly restrictive security can stifle innovation and slow things down. Developers can get frustrated, and the business can't move as quickly as it needs to. Plus, sometimes those super strict rules can even create workarounds that actually make things less secure in the long run. The New Way: Flexible Guardrails. We need to move towards security that provides clear boundaries (the "guardrails") but also allows for agility and flexibility. Think of it like setting clear traffic laws – you know what's allowed and what's not, but you can still drive where you need to go. This means defining security policies that are adaptable to different cloud environments and business needs. It's about enabling secure innovation, not blocking it. We need to find that sweet spot where security empowers the business instead of hindering it. Mindset Shift #5: From "Security is a Cost Center" to "Security is a Business Enabler" Sometimes, security gets seen as just an expense, something we have to do but doesn't really add value. It's like thinking of insurance as just another bill. The Problem: When security is viewed as just a cost, it often gets underfunded or seen as a roadblock. This can lead to cutting corners and ultimately increasing risk. It's like trying to save money by neglecting the brakes on your car – it might seem cheaper in the short term, but it can have disastrous consequences later. The New Way: Security as a Business Enabler. We need to flip this thinking! Strong security isn't just about preventing bad things from happening; it's about building trust with customers, enabling new business opportunities, and ensuring the long-term resilience of the organization. Think of it like a strong foundation for a building – without it, you can't build anything lasting. By building security into our processes and products from the start, we can actually accelerate innovation and gain a competitive advantage. It's about showing our customers that we take their data seriously and that they can trust us. Wrapping Up: Moving to a multi-cloud world is exciting, but it definitely throws some curveballs at how we think about security. By adopting these five new mindsets, we can ditch the outdated castle mentality and build a more agile, collaborative, and ultimately more secure future for our organizations. It's not about being perfect overnight, but about starting to shift our thinking and embracing these new approaches. So, let's level up our security game together!

Application Connectivity Management Achieving policy-driven application-centric security management for Cisco Nexus Dashboard Orchestrat Jeremiah Cornelius 2 min read Jeremiah Cornelius Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 1/2/24 Published Jeremiah Cornelius, Technical Lead for Alliances and Partners at AlgoSec, discusses how Cisco Nexus Dashboard Orchestrator (NDO) users can achieve policy-driven application-centric security management with AlgoSec. Leading Edge of the Data Center with AlgoSec and Cisco NDO AlgoSec ASMS A32.6 is our latest release to feature a major technology integration, built upon our well-established collaboration with Cisco — bringing this partnership to the front of the Cisco innovation cycle with support for Nexus Dashboard Orchestrator (NDO) . NDO allows Cisco ACI – and legacy-style Data Center Network Management – to operate at scale in a global context, across data center and cloud regions. The AlgoSec solution with NDO brings the power of our intelligent automation and software-defined security features for ACI, including planning, change management, and microsegmentation, to this global scope. I urge you to see what AlgoSec delivers for ACI with multiple use cases, enabling application-mode operation and microsegmentation, and delivering integrated security operations workflows. AlgoSec now brings support for Shadow EPG and Inter-Site Contracts with NDO, to our existing ACI strength. Let’s Change the World by Intent I had my first encounter with Cisco Application Centric Infrastructure in 2014 at a Symantec Vision conference. The original Senior Product Manager and Technical Marketing lead were hosting a discussion about the new results from their recent Insieme acquisition and were eager to onboard new partners with security cases and added operations value. At the time I was promoting the security ecosystem of a different platform vendor, and I have to admit that I didn’t fully understand the tremendous changes that ACI was bringing to security for enterprise connectivity. It’s hard to believe that it’s now seven years since then and that Cisco ACI has mainstreamed software-defined networking — changing the way that network teams had grown used to running their networks and devices since at least the mid-’90s. Since that 2014 introduction, Cisco’s ACI changed the landscape of data center networking by introducing an intent-based approach, over earlier configuration-centric architecture models. This opened the way for accelerated movement by enterprise data centers to meet their requirements for internal cloud deployments, new DevOps and serverless application models, and the extension of these to public clouds for hybrid operation – all within a single networking technology that uses familiar switching elements. Two new, software-defined artifacts make this possible in ACI: End-Point Groups (EPG) and Contracts – individual rules that define characteristics and behavior for an allowed network connection. ACI Is Great, NDO Is Global That’s really where NDO comes into the picture. By now, we have an ACI-driven data center networking infrastructure, with management redundancy for the availability of applications and preserving their intent characteristics. Through the use of an infrastructure built on EPGs and contracts, we can reach from the mobile and desktop to the datacenter and the cloud. This means our next barrier is the sharing of intent-based objects and management operations, beyond the confines of a single data center. We want to do this without clustering types, that depend on the availability risk of individual controllers, and hit other limits for availability and oversight. Instead of labor-intensive and error-prone duplication of data center networks and security in different regions, and for different zones of cloud operation, NDO introduces “stretched” shadow EPGs, and inter-site contracts, for application-centric and intent-based, secure traffic which is agnostic to global topologies – wherever your users and applications need to be. NDO Deployment Topology – Image: Cisco Getting NDO Together with AlgoSec: Policy-Driven, App-Centric Security Management  Having added NDO capability to the formidable shared platform of AlgoSec and Cisco ACI, regional-wide and global policy operations can be executed in confidence with intelligent automation. AlgoSec makes it possible to plan for operations of the Cisco NDO scope of connected fabrics in application-centric mode, unlocking the ACI super-powers for micro-segmentation. This enables a shared model between networking and security teams for zero-trust and defense-in-depth, with accelerated, global-scope, secure application changes at the speed of business demand — within minutes, rather than days or weeks. Change management : For security policy change management this means that workloads may be securely re-located from on-premises to public cloud, under a single and uniform network model and change-management framework — ensuring consistency across multiple clouds and hybrid environments. Visibility : With an NDO-enabled ACI networking infrastructure and AlgoSec’s ASMS, all connectivity can be visualized at multiple levels of detail, across an entire multi-vendor, multi-cloud network. This means that individual security risks can be directly correlated to the assets that are impacted, and a full understanding of the impact by security controls on an application’s availability. Risk and Compliance : It’s possible across all the NDO connected fabrics to identify risk on-premises and through the connected ACI cloud networks, including additional cloud-provider security controls. The AlgoSec solution makes this a self-documenting system for NDO, with detailed reporting and an audit trail of network security changes, related to original business and application requests. This means that you can generate automated compliance reports, supporting a wide range of global regulations, and your own, self-tailored policies. The Road Ahead Cisco NDO is a major technology and AlgoSec is in the early days with our feature introduction, nonetheless, we are delighted and enthusiastic about our early adoption customers. Based on early reports with our Cisco partners, needs will arise for more automation, which would include the “zero-touch” push for policy changes – committing Shadow EPG and Inter-site Contract changes to the orchestrator, as we currently do for ACI APIC. Feedback will also shape a need for automation playbooks and workflows that are most useful in the NDO context, and that we can realize with a full committable policy by the ASMS Firewall Analyzer. Contact Us! I encourage anyone interested in NDO and enhancing their operational maturity in aligned network and security operation, to talk to us about our joint solution. We work together with Cisco teams and resellers and will be glad to share more.

Top 10 cloud security tips and best practices for 2025 Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. Top 10 cloud security tips & best practices for 2025 This year’s cloud security recommendations look slightly different from previous years. There are two key reasons for this: New technologies like GenAI and agentic apps have emerged. Attackers are using more sophisticated techniques to exploit cloud assets and evade detection. For example, what used to be basic, easy-to-spot phishing has now become extensive vishing and deep-fake campaigns that even technical experts fall for. To stay ahead of 2025’s threats, the following cloud security best practices are essential. Quick review: What is cloud security and why are cloud security best practices important? Cloud security consists of the controls, policies, and technologies implemented for protecting cloud environments from threats. This includes data, services, applications, configurations, and GenAI models in the cloud. As access to technology has democratized how threat actors launch attacks, cloud security has taken on new meaning and is no longer solely about defense. With cutting-edge tools that often rival many organizations’ defenses at attackers’ disposal, proactive prevention is a must. 10 tips for cloud security Implementing the following recommendations will increase the security of your cloud assets and enhance your overall security posture. 1. Understand the shared responsibility model Traditionally, CSPs (e.g., AWS, Azure, GCP) handle securing your underlying cloud infrastructure and managed services. You, as the customer, need to secure everything running in the cloud (data, applications, configurations, etc.). However, with the arrival of GenAI, companies now also have to worry about safeguarding AI data and AI models. Tips: Understand and embrace your roles as specified by your provider. Establish explicit agreements with providers and supply chain vendors to ensure the integrity of third-party assets. Facilitate shared accountability. 2. Prioritize AI security New technologies come with unknown risks, and adopting them without proper safeguards is an invitation to attack. Tips: Use software composition analysis (SCA) to detect and block vulnerable AI packages to eliminate backdoors that hackers could exploit to attack your cloud environment. Protect your AI training data, model tuning pipelines, and inference endpoints with encryption, strict access controls, and AI-specific guardrails (e.g., model drift detection). Verify provider-enforced tenant isolation to safeguard your AI workloads from multi-tenant risks like data leakage and unauthorized access. Continuously monitor model behavior to spot common AI risks such as model poisoning and compromised AI APIs. Implement input/output validation using dedicated filtering tools (e.g., NVIDIA NeMo Guardrails) to block prompt injection, data exfiltration, and similar attacks. 3. Adopt shift-left security Shift-left security is the practice of securing cloud-native applications and APIs from the development phase. This dramatically reduces your threat footprint and remediation costs. Tips: Embrace secure coding ; integrate automated security and compliance checks (triggered at every pull request or commit) into the CI pipeline; this instantly flags and resolves vulnerable or non-compliant code before it goes live. Use secure container images from trusted sources; scanning for vulnerabilities enhances runtime security and minimizes potential attacker entry points. Store secrets securely (e.g., in HashiCorp Vault) and embed secret detection into developer workflows to uncover hardcoded secrets; this prevents threat actors from gaining a foothold in your cloud environment via exposed secrets. Shield-right as you shift-left, e.g., by enforcing real-time monitoring to detect any blind spots early; this helps deter hackers, who thrive on missed vulnerabilities. 4. Manage identity and access with least privilege and zero trust Embrace centralized identity and access management (IAM), defining policies that govern who can access what. Tips: Implement least privilege (e.g., via RBAC and ABAC), ensuring only essential human and machine identities can access cloud and AI workloads. Adopt a zero trust architecture, segmenting workloads and continuously verifying access rights with MFA, within and outside your network perimeter. Regularly review access rights to revoke unnecessary permissions. 5. Harden configurations Cloud assets, AI workloads, networks, and identities are all pretty easy to misconfigure—making them top causes of breaches. Tips: Validate IaC templates to eliminate security risks before code is shipped. Continuously assess cloud configurations to resolve publicly exposed assets fast. Autonomously enforce security policies with PaC for consistent security and compliance across hybrid and multi-cloud workloads. Enforce timely patching with automated patch management tools to fix vulnerabilities before they become attack vectors. Regularly audit firewall rules to spot misconfigurations that could compromise your cloud resources and networks. 6. Address shadow IT Shadow IT elements (e.g., unsanctioned VMs, data, APIs, and GPUs) are top security risks because they evade centralized governance and monitoring. Tips: Establish policies that balance security with productivity to eliminate the need to bypass centralized security. Automatically block unauthorized deployments from the source, using policies that require resources to be provisioned solely through approved templates. Continuously monitor data flows to discover and resolve shadow IT. 7. Embrace real-time monitoring, detection, and response Continuous monitoring spots threats and anomalies, such as unusual login patterns or configuration changes, before full-blown attacks occur. Tips: Track user behavior in real time to spot lateral movement, model misuse, and other early warning signs of attacks. Predict and prevent potential threats by using AI-powered analytics. Map external exposures to real-world attacker tactics, techniques, and procedures (TTPs) using frameworks like MITRE. 8. Encrypt data Encrypting data and storing encryption keys securely keeps data undecipherable in the event of a breach. However, with the rise of AI and edge computing, you need more than encryption in transit (TLS) and at rest (AES). Tips: Leverage confidential computing techniques like hardware-enforced trusted execution environments (TEEs) for encryption in use (during processing, e.g., for AI model training). Future-proof your data with quantum-resistant cryptography, like hash or code-based cryptography. 9. Automate compliance management Regulatory standards change frequently as technologies and security risks evolve. Companies must stay on top of their compliance posture . Tips: Use automated compliance management tools that keep up with evolving frameworks, including AI-specific standards like the NIST AI RMF and EU AI Act, as well as new policies from PCI DSS, NIST, etc. Maintain regular audit trails to provide audit-ready proof demonstrating your compliance with regulatory bodies and customers. 10. Incident management Having incident management procedures, including prevention and response playbooks, means teams are not left scrambling when incidents happen, i.e., when tensions are usually high and mistakes costly. Tips: Automate incident response with tools that offer autonomous context-based remediation and AI-augmented playbooks; this shortens the compromise-to-containment window. Educate teams on how to secure software development, safeguard third-party component usage, and deal with AI-powered phishing campaigns. Implementing cloud security best practices with AlgoSec Security breaches are costly, with the average figure now standing at $4.44 million , according to IBM’s 2025 Cost of a Data Breach Report.

Learn about the essential firewall change management process. Understand how to implement, track, and control changes to your firewall configurations for optimal security and compliance. Firewall change management process: How does It work? Are network firewalls adequately managed in today's complex environment? For more than two decades, we have been utilizing network firewalls, yet we’re still struggling to properly manage them. In today’s world of information-driven businesses there’s a lot more that can go wrong— and a lot more to lose—when it comes to firewalls, firewall policy management and overall network security. Network environments have become so complex that a single firewall configuration change can take the entire network offline and expose your business to cyber-attacks. Schedule a Demo Why you need firewall change management processes Improperly managed firewalls create some of the greatest business risks in any organization, however often you don’t find out about these risks until it is too late. Outdated firewall rules can allow unauthorized network access which result in cyber-attacks and gaps in compliance with industry and government regulations, while improper firewall rule changes can break business applications. Often, it is simple errors and oversights in the firewall change management process that cause problems, such as opening the network perimeter to security exploits and creating business continuity issues. Therefore, firewall configuration changes present a business challenge that you need to address properly once and for all. Schedule a Demo Firewall change management FAQs Frequently asked questions about the firewall change management process How can I manage firewall changes? In IT, things are constantly in a state of flux. The firewall change management process is one of the biggest problems that businesses face, however, if you can manage the firewall configuration changes consistently over time, then you’ve already won half the battle. You’ll not only have a more secure network environment, but you will allow IT to serve its purpose by facilitating business rather than getting in the way. To manage firewall changes properly, it’s critical to have well-documented and reasonable firewall policies and procedures, combined with automation controls, such as AlgoSec’s security policy management solution, to help with enforcement and oversight. With AlgoSec you can automate the entire firewall change management process: Process firewall changes with zero-touch automation in minutes, instead of days – from planning and design through to deployment on the device – while maintaining full control and ensuring accuracy Leverage topology awareness to identify all the firewalls that are affected by a proposed change Proactively assess the impact of every firewall change before it is implemented to ensure security and continuous compliance with regulatory and corporate standards Automate rule recertification processes while also identifying firewall rules which are out of date, unused or unnecessary Reconcile change requests with the actual changes performed, to identify any changes that were performed “out of band” Automatically document the entire firewall change management workflow It is also important to analyze the impact firewall changes will have on the business. The ideal way is to utilize AlgoSec’s firewall policy management solution to test different scenarios before pushing them out to production. Once AlgoSec and your processes are integrated with your overall change management workflow, you can set your business up for success instead of creating a “wait and see” situation, and “hoping” everything works out. Simply put, if you don’t have the proper insight and predictability, then you’ll set up your business and yourself for failure. How can I assess the risk of my firewall policies? As networks become more complex and firewall rulesets continue to grow, it becomes increasingly difficult to identify and quantify the risk caused by misconfigured or overly permissive firewall rules. A major contributor to firewall policy risks is lack of understanding of exactly what the firewall is doing at any given time. Even if traffic is flowing and applications are working, it doesn’t mean you don’t have unnecessary exposure. All firewall configuration changes either move your network towards better security or increased risks. Even the most experienced firewall administrator can make mistakes. Therefore, the best approach for minimizing firewall policy risks is to use automated firewall policy management tools to help find and fix the security risks before they get out of control. Automated firewall policy management tools, such as AlgoSec, employ widely-accepted firewall best practices and can analyze your current environment to highlight gaps and weaknesses. AlgoSec can also help tighten overly permissive rules (e.g., “ANY” service) by pinpointing the traffic that is flowing through any given rule. Combining policy analysis with the right tools allows you to be proactive with firewall security rather than finding out about the risks once it’s too late. How can I maintain optimized firewall rulesets? Maintaining a clean set of firewall rules is one of the most important functions in network security. Unwieldy rulesets are not just a technical nuisance—they also create business risks, such as open ports and unnecessary VPN tunnels, conflicting rules that create backdoor entry points, and an enormous amount of unnecessary complexity. In addition, bloated rulesets significantly complicate the auditing process, which often involves a review of each rule and its related business justification. This creates unnecessary costs for the business and wastes precious IT time. Examples of problematic firewall rules include unused rules, shadowed rules, expired rules, unattached objects and rules that are not ordered optimally (e.g. the most hit rule is at the bottom of the policy, creating unnecessary firewall overhead). Proactive and periodic checks can help eliminate rule base oversights and allow you to maintain a firewall environment that facilitates security rather than exposes weaknesses. To effectively manage your firewall rulesets, you need the right firewall administrator tools, such as AlgoSec, that will provide you with the visibility needed to see which rules can be eliminated or optimized, and what the implications are of removing or changing a rule. AlgoSec can also automate the change process, eliminating the need for time-consuming and inaccurate manual checks. You also need to ensure that you manage the rulesets on all firewalls. Picking and choosing certain firewalls is like limiting the scope of a security assessment to only part of your network. Your results will be limited, creating a serious false sense of security. It’s fine to focus on your most critical firewalls initially, but you need to address the rulesets across all firewalls eventually.

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

Tags Share this article 6/20/23 Published The past few years have witnessed a rapid surge in the use of SaaS applications across various industries. But with this growth comes a significant challenge: managing security and assessing risk in application connectivity. In this blog, I’ll explore the fascinating insights from a recent study conducted by the Cloud Security Alliance (CSA). The study delves into the complexities of managing security and assessing the risk of application connectivity in the rapidly growing world of SaaS applications and cloud environments. With responses from 1,551 IT and security professionals from organizations of all sizes and from all corners of the globe, this study provides valuable insights into the challenges of application security in cloud environments and how to best manage them. Insight # 1 – Human error is the leading cause of application outages With more than half of these outages linked to manual processes and the increasing complexity of the systems themselves, businesses are losing productivity, revenue, and even reputation due to downtime. In many cases, the root cause of these outages is traced back to configuration errors, software bugs, or human mistakes during deployments or maintenance activities. To combat these issues, investment in automation and machine learning technologies can mitigate the risk of human error and ensure the reliability and stability of their applications. Insight # 2 – 75% of organizations experienced application outages lasting an hour or more. The financial impact of outages has been significant, with an estimated cost of $300,000 or more per instance. These costs include lost productivity, revenue, and potential customer churn. While human error is the major contributor to downtime, outages are often caused by a combination of additional factors, including hardware or software failure and cyber-attacks. Comprehensive disaster recovery plans, backup systems, and application performance monitoring tools are necessary to minimize outages and ensure business continuity. Insight # 3 – A lack of visibility and compliance are the primary constraints to rolling out new applications . Visibility is essential to understanding how applications are used, where they are deployed, and how they integrate with other systems. Compliance gaps, on the other hand, can pose significant risks, resulting in issues such as data breaches, regulatory fines, or reputational damage. To ensure successful application rollout, organizations must have a clear view of their application environment and ensure compliance with relevant standards and regulations. Insight # 4 – The shift to the DevOps methodology has led to a shift-left movement where security is integrated into the application development process . Traditionally, application security teams have been responsible for securing applications in the public cloud. However, DevOps teams are becoming more involved in the security of applications in the public cloud. DevOps teams are now responsible for ensuring that applications are designed with security in mind, and they work with the application security teams to ensure that the necessary controls are in place. Involving the DevOps teams in the security process can reduce the risk of security breaches and ensure that security is integrated throughout the application lifecycle. Insight # 5 – Organizations are targeting unauthorized access to applications in the public cloud . Organizations can protect their applications by implementing strong authentication mechanisms, access controls, and encryption to protect sensitive data. Using the principle of least privilege can limit application access to only authorized personnel. cloud infrastructure is secure and that vulnerabilities are regularly identified and addressed. Organizations must review their security requirements, monitor the application environment, and regularly update their security controls to protect their data and applications in the public cloud. Insight # 6 – A rapidly evolving technology landscape has created skills gaps and staffing issues Specialized skills are not always readily available within organizations, which can result in a shortage of qualified personnel. This can overburden teams, resulting in burnout and increased staff turnover. Staffing shortages can also lead to knowledge silos, where critical skills and knowledge are concentrated in a few key individuals, leaving the rest of the team vulnerable to knowledge gaps. Organizations must invest in training and development programs to ensure that their teams have the skills and knowledge necessary to succeed in their roles. Successful cloud migrations require a comprehensive knowledge of cloud security controls and how they interconnect and collaborate with on-premise security systems. To make this happen, organizations need complete visibility across both cloud and on-premise environments, and must automate the network security management processes. To sum up, the rapidly evolving threat environment demands new ways to enhance security. Proactive risk detection, powerful automation capabilities, and enhanced visibility in the cloud and outside of it are just a few ways to strengthen your security posture. AlgoSec can do all that, and more, to help you stay ahead of emerging threats and protect your critical assets..

Tags Share this article 8/10/15 Published Last week our CTO, Professor Avishai Wool, presented a technical webinar on the do’s and don’ts for managing external connectivity to and from your network . We kicked off our webinar by polling the audience (186 people) on how many external permanent connections into their enterprise network they have. 40% have less than 50 external connections 31% have 50-250 external connections 24% have more than 250 external connections 5% wish they knew how many external connections they have! Clearly this is a very relevant issue for many enterprises, and one which can have a profound effect on security. The webinar covered a wide range of best practices for managing the external connectivity lifecycle and I highly recommend that you view the full presentation. But in the meantime, here are a few key issues that you should be mindful of when considering how to manage external connectivity to and from your network: Network Segmentation While there has to be an element of trust when you let an external partner into your network, you must do all you can to protect your organization from attacks through these connections. These include placing your servers in a demilitarized zone (DMZ), segregating them by firewalls, restricting traffic in both directions from the DMZ as well as using additional controls such as web application firewalls, data leak prevention and intrusion detection. Regulatory Compliance Bear in mind that if the data being accessed over the external connection is regulated, both your systems and the related peer’s systems are now subject t. So if the network connection touches credit card data, both sides of the connection are in scope, and outsourcing the processing and management of regulated data to a partner does not let you off the hook. Maintenance Sometimes you will have to make changes to your external connections, either due to planned maintenance work by your IT team or the peer’s team, or as a result of unplanned outages. Dealing with changes that affect external connections is more complicated than internal maintenance, as it will probably require coordinating with people outside your organisation and tweaking existing workflows, while adhering to any contractual or SLA obligations. As part of this process, remember that you’ll need to ensure that your information systems allow your IT teams to recognize external connections and provide access to the relevant technical information in the contract, while supporting the amended workflows. Contracts In most cases there is a contract that governs all aspects of the external connection – including technical and business issues. The technical points will include issues such as IP addresses and ports, technical contact points, SLAs, testing procedures and the physical location of servers. It’s important, therefore, that this contract is adhered to whenever dealing with technical issues related to external connections. These are just a few tips and issues to be aware of.

Uncategorized How to Perform a Network Security Risk Assessment in 6 Steps Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 1/18/24 Published For your organization to implement robust security policies, it must have clear information on the security risks it is exposed to. An effective IT security plan must take the organization’s unique set of systems and technologies into account. This helps security professionals decide where to deploy limited resources for improving security processes. Cybersecurity risk assessments provide clear, actionable data about the quality and success of the organization’s current security measures. They offer insight into the potential impact of security threats across the entire organization, giving security leaders the information they need to manage risk more effectively. Conducting a comprehensive cyber risk assessment can help you improve your organization’s security posture, address security-related production bottlenecks in business operations, and make sure security team budgets are wisely spent. This kind of assessment is also a vital step in the compliance process . Organizations must undergo information security risk assessments in order to meet regulatory requirements set by different authorities and frameworks, including: The Health Insurance Portability and Accountability Act (HIPAA), The International Organization for Standardization (ISO) The National Institute of Standards and Technology (NIST) Cybersecurity Framework The Payment Card Industry Data Security Standard (PCI DSS) General Data Protection Regulation (GDPR) What is a Security Risk Assessment? Your organization’s security risk assessment is a formal document that identifies, evaluates, and prioritizes cyber threats according to their potential impact on business operations. Categorizing threats this way allows cybersecurity leaders to manage the risk level associated with them in a proactive, strategic way. The assessment provides valuable data about vulnerabilities in business systems and the likelihood of cyber attacks against those systems. It also provides context into mitigation strategies for identified risks, which helps security leaders make informed decisions during the risk management process. For example, a security risk assessment may find that the organization needs to be more reliant on its firewalls and access control solutions . If a threat actor uses phishing or social engineering to bypass these defenses (or take control of them entirely), the entire organization could suffer a catastrophic data breach. In this case, the assessment may recommend investing in penetration testing and advanced incident response capabilities. Organizations that neglect to invest in network security risk assessments won’t know their weaknesses until after they are actively exploited. By the time hackers launch a ransomware attack, it’s too late to consider whether your antivirus systems are properly configured against malware. Who Should Perform Your Organization’s Cyber Risk Assessment? A dedicated internal team should take ownership over the risk assessment process . The process will require technical personnel with a deep understanding of the organization’s IT infrastructure. Executive stakeholders should also be involved because they understand how information flows in the context of the organization’s business logic, and can provide broad insight into its risk management strategy . Small businesses may not have the resources necessary to conduct a comprehensive risk analysis internally. While a variety of assessment tools and solutions are available on the market, partnering with a reputable managed security service provider is the best way to ensure an accurate outcome. Adhering to a consistent methodology is vital, and experienced vulnerability assessment professionals ensure the best results. How to Conduct a Network Security Risk Assessment 1. Develop a comprehensive asset map The first step is accurately mapping out your organization’s network assets. If you don’t have a clear idea of exactly what systems, tools, and applications the organization uses, you won’t be able to manage the risks associated with them. Keep in mind that human user accounts should be counted as assets as well. The Verizon 2023 Data Breach Investigation Report shows that the human element is involved in more than a quarter of all data breaches. The better you understand your organization’s human users and their privilege profiles, the more effectively you can protect them from potential threats and secure critical assets effectively. Ideally, all of your organization’s users should be assigned and managed through a centralized system. For Windows-based networks, Active Directory is usually the solution that comes to mind. Your organization may have a different system in place if it uses a different operating system. Also, don’t forget about information assets like trade secrets and intellectual property. Cybercriminals may target these assets in order to extort the organization. Your asset map should show you exactly where these critical assets are stored, and provide context into which users have permission to access them. Log and track every single asset in a central database that you can quickly access and easily update. Assign security value to each asset as you go and categorize them by access level . Here’s an example of how you might want to structure that categorization: Public data. This is data you’ve intentionally made available to the public. It includes web page content, marketing brochures, and any other information of no consequence in a data breach scenario. Confidential data. This data is not publicly available. If the organization shares it with third parties, it is only under a non-disclosure agreement. Sensitive technical or financial information may end up in this category. Internal use only. This term refers to data that is not allowed outside the company, even under non-disclosure terms. It might include employee pay structures, long-term strategy documents, or product research data. Intellectual property. Any trade secrets, issued patents, or copyrighted assets are intellectual property. The value of the organization depends in some way on this information remaining confidential. Compliance restricted data. This category includes any data that is protected by regulatory or legal obligations. For a HIPAA-compliant organization, that would include patient data, medical histories, and protected personal information. This database will be one of the most important security assessment tools you use throughout the next seven steps. 2. Identify security threats and vulnerabilities Once you have a comprehensive asset inventory, you can begin identifying risks and vulnerabilities for each asset. There are many different types of tests and risk assessment tools you can use for this step. Automating the process whenever possible is highly recommended, since it may otherwise become a lengthy and time-consuming manual task. Vulnerability scanning tools can automatically assess your network and applications for vulnerabilities associated with known threats. The scan’s results will tell you exactly what kinds of threats your information systems are susceptible to, and provide some information about how you can remediate them. Be aware that these scans can only determine your vulnerability to known threats. They won’t detect insider threats , zero-day vulnerabilities and some scanners may overlook security tool misconfigurations that attackers can take advantage of. You may also wish to conduct a security gap analysis. This will provide you with comprehensive information about how your current security program compares to an established standard like CMMC or PCI DSS. This won’t help protect against zero-day threats, but it can uncover information security management problems and misconfigurations that would otherwise go unnoticed. To take this step to the next level, you can conduct penetration testing against the systems and assets your organization uses. This will validate vulnerability scan and gap analysis data while potentially uncovering unknown vulnerabilities in the process. Pentesting replicates real attacks on your systems, providing deep insight into just how feasible those attacks may be from a threat actor’s perspective. When assessing the different risks your organization faces, try to answer the following questions: What is the most likely business outcome associated with this risk? Will the impact of this risk include permanent damage, like destroyed data? Would your organization be subject to fines for compliance violations associated with this risk? Could your organization face additional legal liabilities if someone exploited this risk? 3. Prioritize risks according to severity and likelihood Once you’ve conducted vulnerability scans and assessed the different risks that could impact your organization, you will be left with a long list of potential threats. This list will include more risks and hazards than you could possibly address all at once. The next step is to go through the list and prioritize each risk according to its potential impact and how likely it is to happen. If you implemented penetration testing in the previous step, you should have precise data on how likely certain attacks are to take place. Your team will tell you how many steps they took to compromise confidential data, which authentication systems they had to bypass, and what other security functionalities they disabled. Every additional step reduces the likelihood of a cybercriminal carrying out the attack successfully. If you do not implement penetration testing, you will have to conduct an audit to assess the likelihood of attackers exploiting your organization’s vulnerabilities. Industry-wide threat intelligence data can give you an idea of how frequent certain types of attacks are. During this step, you’ll have to balance the likelihood of exploitation with the severity of the potential impact for each risk. This will require research into the remediation costs associated with many cyberattacks. Remediation costs should include business impact – such as downtime, legal liabilities, and reputational damage – as well as the cost of paying employees to carry out remediation tasks. Assigning internal IT employees to remediation tasks implies the opportunity cost of diverting them from their usual responsibilities. The more completely you assess these costs, the more accurate your assessment will be. 4. Develop security controls in response to risks Now that you have a comprehensive overview of the risks your organization is exposed to, you can begin developing security controls to address them. These controls should provide visibility and functionality to your security processes, allowing you to prevent attackers from exploiting your information systems and detect them when they make an attempt. There are three main types of security control available to the typical organization: Physical controls prevent unauthorized access to sensitive locations and hardware assets. Security cameras, door locks, and live guards all contribute to physical security. These controls prevent external attacks from taking place on premises. Administrative controls are policies, practices, and workflows that secure business assets and provide visibility into workplace processes. These are vital for protecting against credential-based attacks and malicious insiders. Technical controls include purpose-built security tools like hardware firewalls, encrypted data storage solutions, and antivirus software. Depending on their configuration, these controls can address almost any type of threat. These categories have further sub-categories that describe how the control interacts with the threat it is protecting against. Most controls protect against more than one type of risk, and many controls will protect against different risks in different ways. Here are some of the functions of different controls that you should keep in mind: Detection-based controls trigger alerts when they discover unauthorized activity happening on the network. Intrusion detection systems (IDS) and security information and event management (SIEM) platforms are examples of detection-based solutions. When you configure one of these systems to detect a known risk, you are implementing a detection-based technical control. Prevention-based controls block unauthorized activity from taking place altogether. Authentication protocols and firewall rules are common examples of prevention-based security controls. When you update your organization’s password policy, you are implementing a prevention-based administrative control. Correction and compensation-based controls focus on remediating the effects of cyberattacks once they occur. Disaster recovery systems and business continuity solutions are examples. When you copy a backup database to an on-premises server, you are establishing physical compensation-based controls that will help you recover from potential threats. 5. Document the results and create a remediation plan Once you’ve assessed your organization’s exposure to different risks and developed security controls to address those risks, you are ready to condense them into a cohesive remediation plan . You will use the data you’ve gathered so far to justify the recommendations you make, so it’s a good idea to present that data visually. Consider creating a risk matrix to show how individual risks compare to one another based on their severity and likelihood. High-impact risks that have a high likelihood of occurring should draw more time and attention than risks that are either low-impact, unlikely, or both. Your remediation plan will document the steps that security teams will need to take when responding to each incident you describe. If multiple options exist for a particular vulnerability, you may add a cost/benefit analysis of multiple approaches. This should provide you with an accurate way to quantify the cost of certain cyberattacks and provide a comparative cost for implementing controls against that type of attack. Comparing the cost of remediation with the cost of implementing controls should show some obvious options for cybersecurity investment. It’s easy to make the case for securing against high-severity, high-likelihood attacks with high remediation costs and low control costs. Implementing security patches is an example of this kind of security control that costs very little but provides a great deal of value in this context. Depending on your organization’s security risk profile, you may uncover other opportunities to improve security quickly. You will probably also find opportunities that are more difficult or expensive to carry out. You will have to pitch these opportunities to stakeholders and make the case for their approval. 6. Implement recommendations and evaluate the effectiveness of your assessment Once you have approval to implement your recommendations, it’s time for action. Your security team can now assign each item in the remediation plan to the team member responsible and oversee their completion. Be sure to allow a realistic time frame for each step in the process to be completed – especially if your team is not actively executing every task on its own. You should also include steps for monitoring the effectiveness of their efforts and documenting the changes they make to your security posture. This will provide you with key performance metrics that you can compare with future network security assessments moving forward, and help you demonstrate the value of your remediation efforts overall. Once you have implemented the recommendations, you can monitor and optimize the performance of your information systems to ensure your security posture adapts to new threats as they emerge. Risk assessments are not static processes, and you should be prepared to conduct internal audits and simulate the impact of configuration changes on your current deployment. You may wish to repeat your risk evaluation and gap analysis step to find out how much your organization’s security posture has changed. You can use automated tools like AlgoSec to conduct configuration simulations and optimize the way your network responds to new and emerging threats. Investing time and energy into these tasks now will lessen the burden of your next network security risk assessment and make it easier for you to gain approval for the recommendations you make in the future.
