NIST SP 800-53 Rev. 5 Common Control Library

Browse 1,193 controls and enhancements across 20 security and privacy families. Use the GovRAMP crosswalk to locate controls referenced by Security Snapshot, Core, and Moderate.

A shared catalog supports common-control planning; designation as a common, hybrid, or system-specific control depends on your organization’s implementation and inheritance decisions.

Sources and crosswalk scope

NIST OSCAL content 5.1.1+u4, retrieved 2026-09-18. GovRAMP Snapshot v1.4 and Core selection from Moderate v1.06 reference the December 2020 Rev. 5 text. Mappings establish exact identifier correspondence, not identical requirements, inherited implementation, or GovRAMP authorization. GovRAMP parameters and additional requirements remain authoritative for each program. Full Moderate, High, and other programs are not mapped here. Withdrawn controls are retained for reference.

CP-9 · System Backup

Control statement and discussion

NIST control statement

a. Conduct backups of user-level information contained in [Assignment: system components] [Assignment: frequency]; b. Conduct backups of system-level information contained in the system [Assignment: frequency]; c. Conduct backups of system documentation, including security- and privacy-related documentation [Assignment: frequency] ; and d. Protect the confidentiality, integrity, and availability of backup information.

Discussion

System-level information includes system state information, operating system software, middleware, application software, and licenses. User-level information includes information other than system-level information. Mechanisms employed to protect the integrity of system backups include digital signatures and cryptographic hashes. Protection of system backup information while in transit is addressed by [MP-5](#mp-5) and [SC-8](#sc-8) . System backups reflect the requirements in contingency plans as well as other organizational requirements for backing up information. Organizations may be subject to laws, executive orders, directives, regulations, or policies with requirements regarding specific categories of information (e.g., personal health information). Organizational personnel consult with the senior agency official for privacy and legal counsel regarding such requirements.

Media Protection · Base control

MP-5 · Media Transport

Control statement and discussion

NIST control statement

a. Protect and control [Assignment: types of system media] during transport outside of controlled areas using [Assignment: organization-defined controls]; b. Maintain accountability for system media during transport outside of controlled areas; c. Document activities associated with the transport of system media; and d. Restrict the activities associated with the transport of system media to authorized personnel.

Discussion

System media includes digital and non-digital media. Digital media includes flash drives, diskettes, magnetic tapes, external or removable hard disk drives (e.g., solid state and magnetic), compact discs, and digital versatile discs. Non-digital media includes microfilm and paper. Controlled areas are spaces for which organizations provide physical or procedural controls to meet requirements established for protecting information and systems. Controls to protect media during transport include cryptography and locked containers. Cryptographic mechanisms can provide confidentiality and integrity protections depending on the mechanisms implemented. Activities associated with media transport include releasing media for transport, ensuring that media enters the appropriate transport processes, and the actual transport. Authorized transport and courier personnel may include individuals external to the organization. Maintaining accountability of media during transport includes restricting transport activities to authorized personnel and tracking and/or obtaining records of transport activities as the media moves through the transportation system to prevent and detect loss, destruction, or tampering. Organizations establish documentation requirements for activities associated with the transport of system media in accordance with organizational assessments of risk. Organizations maintain the flexibility to define record-keeping methods for the different types of media transport as part of a system of transport-related records.

Control statement and discussion

NIST control statement

Employ an identified custodian during transport of system media outside of controlled areas.

Discussion

Identified custodians provide organizations with specific points of contact during the media transport process and facilitate individual accountability. Custodial responsibilities can be transferred from one individual to another if an unambiguous custodian is identified.
