NIST 800-53, Rev. 4 vs. Rev. 5 - Notable Differences

The differences between NIST 800-53, Rev. 4 vs. Rev. 5 are considerable as NIST SP 800-53, Revision 5 adds 66 new base controls, 202 new control enhancements and 131 new parameters to existing controls. Furthermore, there are 90 newly withdrawn controls that have been incorporated into or moved to other controls, along with 92 previously withdrawn controls, resulting in a total of 1007 controls and enhancements in NIST SP 800-53, Revision 5.

Other changes include the following:

  • Two additional control families have been added: Personally Identifiable Information Processing and Transparency (PT), and Supply Chain Risk Management (SR).
  • The Program Management family also grew considerably in terms of the number of controls.
  • The privacy measures previously outlined in Appendix J of revision 4 have now been incorporated into the main body of controls.
  • Because of growing supply chain threats, NIST has grouped the supply chain risk management functions into their own family.

Note that NIST SP 800-53, Revision 4 was retired as of September 23rd, 2021, so say hello to NIST SP 800-53, Revision 5 and the massive new control requirements put forth by NIST.
