NIST published SP 800-53 to provide guidelines on security controls for federal information systems. It’s to help agencies develop appropriate security policies and controls to protect all federal information systems. It also offers its Cybersecurity Framework to help organizations understand cybersecurity risks and how to reduce these risks using customized measures.
The framework also helps organizations know how to respond to and recover from cybersecurity incidents—prompting them to analyze root causes and consider how to make improvements.
