Official Requirement

A. Analyze the security and privacy impacts of changes to the system prior to implementation. B. Verify that the security requirements for the system continue to be satisfied after the system changes have been implemented.

In Plain English

Before making any system change, you must assess its security and privacy impact. After the change is implemented, you must verify that security controls still work as expected. This prevents changes from inadvertently weakening your security posture.

On-premises implementation and evidence

Security and privacy impact analysis for changes

Implementation steps

  1. Require a security impact assessment for every change request, documenting which controls may be affected
  2. Have the security team review and sign off on the impact assessment before the change is approved
  3. After implementation, test affected security controls (firewall rules, access controls, logging) to confirm they still function correctly
  4. Document post-implementation testing results in the change record
