🚨Incoming: The Federal Zero Trust Data Security Guide Fresh off the presses - In alignment with M-22-09, the Federal CDO Council and Federal CISO Council gathered a cross-agency team of data and security specialists to develop a comprehensive data security guide for Federal agencies. Representatives from over 30 Federal agencies and departments worked together to produce the Federal Zero Trust Data Security Guide, which: 🔹Establishes the vision and core principles for ZT data security 🔹Details methods to locate, identify, and categorize data with clear, actionable criteria 🔹Enhances data protection through targeted security monitoring and control strategies 🔹Equips practitioners with adaptable best practices to align with their agency’s unique mission requirements Securing the data pillar in Zero Trust has been a challenging endeavor, but it’s foundational to a resilient cybersecurity posture. This guide lays out essential principles and a roadmap to embed security at the core of data management beyond traditional perimeters. Here are a few key takeaways: 🔐 Core ZT Principles: Adopting a data-centric approach with strict access controls, data resiliency, and integration of privacy and compliance from day one. 📊 Data Inventory and Classification: It is crucial to understand the data landscape, and the guide provides insights into cataloging and labeling sensitive data for targeted protection. 🤝 Managing Third-Party Risks: From privacy-preserving technologies to detailed vendor assessments, agencies can better secure shared data and protect it from supply chain threats. I had the privilege of attending a couple of these Working Group meetings before leaving CISA earlier this year, and I congratulate the group on this necessary release. This guide aligns closely with CISA's Zero Trust Maturity Model, providing agencies with a robust framework to secure federal data assets and advance a strong, data-centric ZT security model. #data #zerotust #cybersecurity #technology #informationsecurity #computersecurity #datascience #artificialintelligence #digitaltransformation #bigdata 

Here I attached the Cybersecurity Technology Stack. This poster is a complete visual guide to the key cybersecurity tools and technologies across all major categories from SIEM, EDR, XDR, SOAR, TIP, PAM, CSPM to deception technologies, UEBA and more. I created this to help professionals and newcomers get a clearer picture of what solutions are available and how they fit into the larger cybersecurity ecosystem. When I first started working in cybersecurity operations, most environments focused heavily on perimeter defence and endpoint protection. But attackers have evolved. Today, a proper setup requires multiple integrated layers that work together. No single tool is enough. What matters is how these tools connect to give visibility, control and speed in detection and response. If you're building or reviewing your cybersecurity stack, these are the key areas I recommend you consider: 1. Visibility with SIEM •Start with a strong SIEM platform. This will collect logs across your infrastructure from endpoints, firewalls, cloud and identity systems and help detect patterns or anomalies. 2. Real-time Threat Detection with EDR or XDR •Next, deploy EDR to get deep visibility into endpoint activities. If your budget allows, move towards XDR to combine endpoint, network and cloud telemetry into one detection layer. 3. Response Automation with SOAR •As alerts come in, you need a fast and consistent way to respond. A SOAR platform can automate triage, enrich alerts with threat intel and reduce the time analysts spend on manual tasks. 4. Threat Intelligence Integration •No matter how good your SIEM or EDR is, you need context. Use Threat Intelligence Platforms (TIP) to enrich data with external threat indicators and insights. 5. Secure Privileged Access with PAM •If an attacker gets access to a privileged account, the damage can be severe. Implement PAM to secure, manage and audit access to critical systems and credentials. 6. Vulnerability Management •A well-monitored environment still becomes weak if patching is not managed. Use vulnerability scanners and patch management systems to identify and remediate weaknesses quickly. 7. Cloud Security Posture and Identity Management •As more workloads move to the cloud, ensure you have CSPM tools and proper IAM controls in place to prevent misconfigurations and abuse of identity-based access. 8. Advanced Detection with NDR, UEBA, and Deception •For mature setups, consider adding Network Detection & Response, User Behaviour Analytics and deception technologies. These give you deeper layers of defence and help detect stealthy attacks. Building a modern cybersecurity setup is not about chasing tools, but designing an architecture where each solution complements the other. You want detection, correlation, automation and response to happen as smoothly as possible. This is the mindset behind the stack I designed. Every component in this poster plays a role in defending against modern threats.

🔐 All-in-One platform vs. Best-of-Breed tools: which #cybersecurity strategy truly defends your business in today’s fast-evolving cyber landscape? According to the latest insights from the CrowdStrike Global Threat Report (GTR), the rise in #ransomware and targeted attacks highlights the urgent need for predictive, AI-driven security systems. Much like the futuristic tech in "Minority Report", today’s cybersecurity solutions aim to anticipate and neutralize threats before they escalate. 🔵 Integrated Platforms consolidate multiple security functions into one system for ease of use but may lead to trade-offs in specific areas. 🔵 Best-of-Breed Solutions allow organizations to hand-pick the best tools for each security function, but may come with integration challenges. 🚀 Many forward-thinking companies like Veeam Software, CrowdStrike, Palo Alto Networks, Commvault, Google, and Rubrik are leading the way with integrated security systems that predict, prevent, and protect in real-time: 🟧 CrowdStrike + Palo Alto Networks: AI-driven threat detection + next-gen firewall = unified defence. 🟧 Rubrik + CrowdStrike: Enhance cyber resilience with AI-powered insights and immutable backups. 🟧 Google + Wiz: Cloud-native security with deep visibility, continuous monitoring, and AI-powered threat detection. 🟧 Veeam Software + Microsoft Security: Cloud-native security with AI-driven backup and disaster recovery. These partnerships underscore the need for hybrid security models that leverage the best of both integrated and specialized solutions to combat increasingly sophisticated cyber threats. 🌐 Why does this matter? As cybercriminals become more advanced, proactive threat detection and #AI response are no longer optional. Organizations are turning to solutions that can detect threats early, protect their assets across hybrid environments, and ensure data resilience—without the complexity. The future of cybersecurity? It's not just about reacting to threats. It's about anticipating and neutralizing them before they occur. 🔍 Read more about the evolution of cybersecurity and why integrated platforms might or might not be the key to the future 👇 #PredictiveSecurity #CyberResilience #DataProtection

AI agents should never receive unrestricted access just because they can complete a task. The more tools, systems, and data an agent can reach, the more carefully its permissions must be designed. These five access control models provide different ways to keep agent actions scoped, secure, and auditable: → 𝗥𝗼𝗹𝗲-𝗕𝗮𝘀𝗲𝗱 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 Permissions are assigned through predefined roles. It works well when responsibilities are stable and agents can be mapped to roles such as support agent, finance agent, or administrator. → 𝗔𝘁𝘁𝗿𝗶𝗯𝘂𝘁𝗲-𝗕𝗮𝘀𝗲𝗱 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 Access decisions use attributes such as agent identity, resource type, requested action, location, time, risk, and business context. This enables more precise and dynamic policies. → 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 𝗟𝗶𝘀𝘁𝘀 Each resource maintains a list of agents or groups allowed to access it and the actions they may perform. This provides direct resource-level control but can become difficult to manage at scale. → 𝗠𝗮𝗻𝗱𝗮𝘁𝗼𝗿𝘆 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 Central authorities assign security labels to agents and resources. Strict policies determine access, and individual users or agents cannot override them. → 𝗖𝗮𝗽𝗮𝗯𝗶𝗹𝗶𝘁𝘆-𝗕𝗮𝘀𝗲𝗱 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 Agents receive scoped tokens that authorize a specific action, resource, limit, or time period. This avoids granting broad standing permissions and works well for temporary, task-specific execution. No single access control model fits every agent workflow. Role-based control provides simplicity. Attribute-based control adds context. ACLs offer direct resource permissions. Mandatory control enforces strict policy. Capability-based control provides narrow, temporary authority. Which access control model best fits the AI agents operating inside your enterprise?

𝗜𝗖𝗦 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹: 𝗞𝗲𝗲𝗽𝗶𝗻𝗴 𝗖𝘆𝗯𝗲𝗿 𝗧𝗵𝗿𝗲𝗮𝘁𝘀 𝗢𝘂𝘁 𝟯:𝟬𝟬 𝗮.𝗺. 𝗶𝗻 𝗮𝗻 𝗲𝗻𝗲𝗿𝗴𝘆 𝗽𝗹𝗮𝗻𝘁: An operator sees the cursor moving—on its own. In 2021, hackers actually took control of a Florida water plant, nearly poisoning the water. Why? Shared passwords and open remote access. Access control in Industrial Control Systems (ICS) isn’t just IT hygiene—it’s a frontline defense. Unlike IT, ICS must balance security vs. uptime, making access control complex. 𝗞𝗲𝘆 𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲𝘀 𝗶𝗻 𝗜𝗖𝗦 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 ❌ Default & Shared Credentials – Many OT devices still use factory-set or hardcoded passwords. ❌ Overprivileged Accounts – Admins using the same account for both daily tasks & critical operations. ❌ Uncontrolled Remote Access – Unrestricted RDP, TeamViewer, or VPN access directly into OT. ❌ Lack of Continuous Audits – Old user accounts lingering long after employees leave. 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗮𝗹 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 (Aligned with IEC 62443) ✏️ Kill Default Credentials – Change all default passwords before deployment. Use compensating controls if you can’t. ✏️ Unique, Least-Privilege Accounts – No shared logins. Admins should have separate work and privileged accounts. ✏️ Secure Remote Access – Jump servers, MFA, and firewalls between IT & OT. No direct access to controllers. ✏️ Regular Audits & Offboarding – Disable accounts immediately when employees or contractors leave. 𝙍𝙚𝙘𝙚𝙣𝙩 𝙇𝙚𝙨𝙨𝙤𝙣: The Florida water plant breach could have been prevented with MFA, segmented access, and unique passwords. Simple steps can block attackers from turning small mistakes into disasters. ICS security is about access—who gets in, what they can do, and when they’re removed. Every login should tell a secure story. #ICS #CyberSecurity #IEC62443 #AccessControl #OTSecurity

Why Identity Access Management Is Critical for Modern Enterprises Identity Access Management (IAM) is the vital part of any robust security architecture - especially as traditional perimeters dissolve in today’s distributed environments. For technical leaders and practitioners, effective IAM isn’t just about authentication. It’s about implementing continuous, granular controls that adapt to organizational change and emerging risk. Key pillars include: User Access Reconciliation: Regular alignment of granted permissions with actual entitlements in critical systems is non-negotiable. Automated and periodic reconciliation detects orphaned accounts and excessive privileges, reducing attack surfaces. Privileged Access Management (PAM): High-risk accounts with broad capabilities must be tightly governed. PAM enforces strict controls such as just-in-time elevation, session monitoring, and audit trails to protect sensitive assets from exploitation. Timely Access Revocation: When users change roles or exit, immediate deprovisioning is crucial. Delays can leave dormant accounts vulnerable to misuse or compromise. Automated workflows ensure access rights are always in sync with current employment status and responsibilities. Principle of Least Privilege: Users should have the minimal access needed to perform their functions - nothing more. This foundational control limits exposure and contains lateral movement in case of breaches. Periodic Role Transition Audits: Role transitions are inevitable. Regular reviews of access entitlements ensure that evolving responsibilities are matched by appropriate authorizations, preventing privilege creep and segregation-of-duty violations. In a zero-trust era, identity is the new perimeter. Mature IAM programs employ multifactor authentication, continuous role audits, and real-time response to changes, providing both agility and security at enterprise scale. #IAM #CyberSecurity #IdentityManagement #PAM #ZeroTrust

Could your security tools be making you less secure? Microsoft tracks over 600 𝒎𝒊𝒍𝒍𝒊𝒐𝒏 𝒄𝒚𝒃𝒆𝒓𝒂𝒕𝒕𝒂𝒄𝒌𝒔 𝒅𝒂𝒊𝒍𝒚 — spanning ransomware, phishing, and identity-based threats. Their analysis reveals that more security tools don’t necessarily mean better security. Data from a recent survey conducted by Foundry supports this: - Companies using fewer security tools reported an average of 10.5 security incidents. - Those relying on more tools reported 15.3 incidents—a 31% increase in security breaches. The question is: Are you still using multiple security tools? Here’s why you should reconsider: 🔗 𝐃𝐢𝐬𝐜𝐨𝐧𝐧𝐞𝐜𝐭𝐞𝐝 𝐓𝐨𝐨𝐥𝐬 𝐂𝐫𝐞𝐚𝐭𝐞 𝐆𝐚𝐩𝐬 Overlapping solutions can result in inconsistent policies and configurations, inadvertently opening doors for attackers. 📊 𝐅𝐫𝐚𝐠𝐦𝐞𝐧𝐭𝐞𝐝 𝐕𝐢𝐬𝐢𝐛𝐢𝐥𝐢𝐭𝐲 A lack of cohesion between tools leads to missed connections, allowing advanced threats to slip through undetected. ⏱️ 𝐒𝐥𝐨𝐰𝐞𝐫 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐞 𝐓𝐢𝐦𝐞𝐬 Siloed systems mean teams waste precious time piecing together data from disparate sources instead of responding swiftly. 💡 𝐓𝐨𝐨𝐥 𝐅𝐚𝐭𝐢𝐠𝐮𝐞 𝐚𝐧𝐝 𝐎𝐯𝐞𝐫𝐡𝐞𝐚𝐝 Managing multiple tools can overwhelm security teams, increasing complexity and administrative overhead.

⏭️After a couple of months, it is time to update the 2025 “Get your Microsoft Defender optimized and configured” cheat sheet In recent years, Microsoft has significantly enhanced Defender’s capabilities and attack posture. With Defender evolving rapidly, “set and forget” is no longer an option. Stay up to date to get the latest innovations and protections. Microsoft continuously adds features, but many require manual configuration. Here’s my updated cheat sheet with the settings I still see overlooked in 2025: 👉𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫 • M365 Unified Audit Log with 12+ months of retention for all event types • Configure MDI sensors (AD/ ADFS/ADFC and ADConnect). It is not only DC anymore • Ensure Attack Disruption is fully configured. Please make sure this is configured, and when possible test the flow with some attacks •  Define and tag critical assets in Exposure Management •  Explore Attack Paths and Choke Points in Exposure Management •  Ensure the correct RBAC is in place and is documented which actions are available for which role 👉𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫 𝐟𝐨𝐫 𝐄𝐧𝐝𝐩𝐨𝐢𝐧𝐭 • Ensure Unified Audit log is enabled in Defender • Enable ASR rules on all Windows Devices in at least audit mode and switch to block mode based on the events. Microsoft recently released new rules, make sure to adopt new rules as well • Windows Server 2012R2 and 2016 still running on MMA agent, please migrate them to the new improved Unified Agent. Or better migrate the OS to one of the latest supported Windows versions • Manage all endpoints via Intune/ MDE-Management or other solutions • Be sure Linux is not for all machines running in passive mode (this is the default) when onboarding Defender/Intune lets you configure various policies, but not all settings are in the default templates. Make sure at least the following are enabled: • EnableFileHashComputation is enabled • Network Protection is enabled (server requires additional configuration, which is not in the policy list) • Firewall is enabled, and Firewall object access auditing is enabled With the above three settings, there is way more data available in Advanced Hunting, and better visibility in the network logs and data around the endpoint And also important: • Configure the hide exclusions for both users and local administrators All of the above settings except Firewall auditing are not available in the Endpoint Security policies, and can be configured via the settings catalog/ security baseline or when not using Intune; with the use of GPO 👉𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫 𝐟𝐨𝐫 𝐂𝐥𝐨𝐮𝐝 𝐀𝐩𝐩𝐬 • Enable App Governance (included in license, often ignored!) • Enable all pre-set policies in App Governance and review the alerts • Connect App Connectors for Microsoft Azure & Microsoft 365 And yes, there are many more items. Stay tuned for more! 👉𝐌𝐮𝐬𝐭 𝐫𝐞𝐚𝐝 𝐛𝐥𝐨𝐠𝐬: https://lnkd.in/dEtk7rCB
