Which NIST publication document is concerned with security categorization of federal information and information systems? Response:

NIST SP 800-39 focuses on managing information security risk organization-wide, not specifically on the categorization of information and systems.

NIST SP 800-137 provides guidance on Information Security Continuous Monitoring (ISCM), which occurs after categorization and control implementation.

FIPS 199, titled 'Standards for Security Categorization of Federal Information and Information Systems,' provides a mandatory standard for federal agencies to categorize their information and information systems based on the potential impact of a security incident. This categorization is foundational for selecting appropriate security controls.

NIST SP 800-53 provides a catalog of security and privacy controls, which are selected based on FIPS 199 categorization, but it does not define the categorization process itself.
