NSA Releases Cyber Hygiene Guidance to Help Defend Against Advanced Threats
September 11, 2026
The National Security Agency has released a best practices guide to help organizations strengthen cyber hygiene and defend against advanced cyber threats, including those using artificial intelligence. The guide recommends immediate steps to reduce risk, including maintaining a network inventory, implementing multifactor authentication and promptly applying security patches.
It also outlines longer-term steps toward zero-trust security, including network segmentation and continuous monitoring. The guidance highlights defenses against AI-enhanced threats such as automated reconnaissance and “living off the land” attacks, which use legitimate tools already present on a victim’s system.
