NIST SP 800-53 Rev 5 MODERATE AC-21: Information Sharing

Enable authorized users to determine whether access authorizations match sharing restrictions.

What else in your programme already covers this

This control maps to 22 controls across 14 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

PCI DSS 4.0 · 4 controls

  • 3.4.1 PAN is masked when displayed (the BIN and last four digits are the maximum number of digits to be displayed), such that only personnel with a legitimate business need can
  • 7.2.4 All user accounts and related access privileges, including third-party/vendor accounts, are reviewed as follows: • At least once every six months. • To ensure user accounts and access remain appropriate based on job function.
  • 7.2.5 All application and system accounts and related access privileges are assigned and managed as follows: • Based on the least privileges necessary for the operability of the system or application. • Access is limited
  • 7.3.1 An access control system(s) is in place that restricts access based on a user's need to know and covers all system components

SOC 2 · 4 controls

  • SOC2-CC6.3 Role-based access and least privilege are enforced
  • SOC2-CC6.7 Transmission of data is restricted to authorized users

  • SOC2-P6.2 Records of personal information disclosures are maintained
  • SEC03-BP07 Analyze public and cross-account access

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
