PCI DSS 4.0 12.3.3: 12.3.3 Cryptographic cipher suite and protocol inventory reviewed annually
The cipher suites and protocols in use must be documented, then checked at least every 12 months, with the review covering at minimum: a current inventory of every cipher suite and protocol in use, stating its purpose and where it is used; active tracking of industry developments on whether each remains viable; and a documented plan for responding to expected changes in cryptographic weaknesses. Applicability: covers every suite and protocol used to satisfy PCI DSS, including those rendering PAN unreadable at rest and in transit, protecting passwords, and supporting authentication. Objective under the customized approach: the entity can react fast to cryptographic protocol or algorithm weaknesses that affect cardholder data protection. Future-dated: treated as a best practice up to 31 March 2025 and mandatory since then.
This control maps to 45 controls across 19 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
You are reading one control. How much of PCI DSS 4.0 have you already done?
PCI DSS 4.0 12.3.3 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.
