Who needs to comply with NIST 800-53?

Organizations required to comply with NIST 800-53 include federal agencies, government contractors, and entities managing or handling federal information systems and data. This compliance is mandated to ensure the security and privacy of federal systems and applies particularly to organizations working with the U.S. government, especially those managing Controlled Unclassified Information (CUI) or other sensitive federal data. Compliance also extends to hosted systems and applications that support these federal functions.

What documentation is required for a NIST 800-53 audit?

A NIST 800-53 audit generally requires extensive documentation to demonstrate compliance with security controls. This typically includes the System Security Plan (SSP), Risk Assessment Report (RAR), Plan of Action and Milestones (POA&M), security policies and procedures, incident response plans, training records, evidence of control implementation, system architecture diagrams, and any previous audit reports or security assessments.

What is the NIST audit process?

The NIST audit process involves verifying an organization’s adherence to NIST standards by assessing security controls, identifying gaps, and creating a remediation plan to address deficiencies. It ensures that security controls function effectively and incorporates ongoing monitoring and improvement activities.
