Key-management policies and procedures must be in place to change each key when its cryptoperiod ends, as set by the relevant application vendor or key owner and informed by industry best practice and guidelines, including: (1) a defined cryptoperiod for every key type in use; and (2) a process for changing keys when that cryptoperiod ends. Guidance defines a cryptoperiod as the span during which a key may be used for its purpose, often expressed as active time and/or volume of ciphertext produced, and cites algorithm strength, key length, compromise risk and data sensitivity as factors, referring to Revision 5 of NIST SP 800-57 Part 1. Objective under the customized approach: keys are not used after their defined cryptoperiod.
This control maps to 16 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.
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.
PCI DSS 4.0 3.7.4 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of PCI DSS 4.0 your existing evidence covers. Hold ISO 27001:2022 and 139 of 280 PCI DSS 4.0 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 415 were rejected on the ISO 27001:2022 pair alone.
The graph holds this control, the 16 it maps to, and the evidence behind each claim, over MCP and REST.
