At the ACS and DS, all key-management activity for the cryptographic keys the PCI 3DS Data Matrix specifies (Table 2 in v1.3: the ACS private key for signed content and the DS private key used to decrypt SDK-encrypted data) takes place in an HSM whose validation is either at Level 3 or above overall under FIPS 140-2, or PCI PTS HSM approved. The assessor examines the key-management procedures and interviews personnel.
This control maps to 3 controls across 3 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.
The graph holds this control, the 3 it maps to, and the evidence behind each claim, over MCP and REST.
