Every item of media with cardholder data must be classified according to how sensitive the data is. The guidance adds that media should be identified so its classification status is apparent, which does not mean it needs a literal confidential label. Applicability: all entities holding cardholder data on media. Customized approach objective: media are classified and given appropriate protection.
This control maps to 28 controls across 17 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 9.4.2 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 28 it maps to, and the evidence behind each claim, over MCP and REST.
