In this special year-end edition, we revisit critical advice from our cybersecurity experts on AI, exposure management, cloud, vulnerability management, OT, and critical infrastructure.<\/h3>\n

Key takeaways<\/h4>\n
    \n
  1. Combating AI threats: Counter autonomous agentic AI attacks and shadow usage by enforcing strict governance and elevating basic cyber hygiene to prevent massive-scale breaches.<\/li>\n
  2. Adopting exposure management: Align security with business objectives by adopting a unified exposure management program to preemptively prioritize and remediate the most critical threats first.<\/li>\n
  3. Securing cloud and critical infrastructure: Reduce attack surfaces by rigorously managing identities to stop “permission creep,” implementing just-in-time (JIT) access, and maintaining precise asset inventories.<\/li>\n<\/ol>\n

    In case you missed it, we\u2019re recapping standout guidance from Tenable experts to help you with agentic AI attacks, overprivileged identities, risk-based metrics, OT inventories, vulnerability prioritization, and geopolitical threats.<\/p>\n

    1 – Defending against agentic AI and managing shadow AI risks<\/h4>\n

    The emergence of agentic AI tools that act autonomously has shifted the threat landscape. Here is how Tenable experts addressed security and governance in this new era.<\/p>\n

    In “Agentic AI Security: Keep Your Cyber Hygiene Failures from Becoming a Global Breach<\/span><\/a>,” Tenable Chief Security Officer Robert Huber warns that the weaponization of legitimate agentic AI coding tools, such as Anthropic’s Claude Code, “proves that neglecting fundamental cyber hygiene allows malicious AI to execute massive-scale attacks with unprecedented speed and low skill.”<\/p>\n

    The good news is that even AI-powered attacks can\u2019t succeed if you\u2019ve closed your most critical exposures, impeding lateral movement and privilege escalation. \u201cElevating the standard of basic security hygiene is essential for our collective defense,\u201d he wrote.<\/p>\n

    Blake Kizer recommends in “A Practical Defense Against AI-led Attacks<\/span><\/a>” a unified, preemptive and predictive exposure management program rooted in security fundamentals. By defining the new AI attack surface and fighting AI with AI, \u201cthe winner will be the team that builds the best partnership between human intuition and algorithmic speed,\u201d writes Kizer, a Staff Information Security Engineer at Tenable.<\/p>\n

    Meanwhile, in “FAQ About Model Context Protocol (MCP) and Integrating with AI for Agentic Applications<\/span><\/a>,” Chad Streck notes that while MCP standardizes connecting data to large language models (LLMs), it raises security concerns developers must address.<\/p>\n
