NSA Releases Network Infrastructure Security Guidance

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 designers and administrators to review the NSA CTR to help prioritize steps needed to harden networks against cyber threats.
