Original release date: March 3, 2022

The National Security Agency (NSA) has released a new Cybersecurity Technical Report (CTR): Network Infrastructure Security Guidance. The report captures best practices based on the depth and breadth of experience in supporting customers and responding to threats. Recommendations include perimeter and internal network defenses to improve monitoring and access controls throughout the network.

CISA encourages network architects, defenders, and administrators to review NSA’s Network Infrastructure Security Guidance as well as CISA’s recently published Layering Network Security Through Segmentation infographic for assistance in hardening networks against cyber threats.
