Select encryption algorithms that suit the classification of the data, the risk it carries and the practical usability of the technology, rather than applying one algorithm everywhere.
What else in your programme already covers this
This control maps to 32 controls across 22 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
12.3.3 Cryptographic cipher suites and protocols inventory
3.5.1.1 Hashes of PAN use keyed cryptographic functions
4.2.1 Strong cryptography and security protocols are implemented as follows to safeguard PAN during transmission over open, public networks: • Only trusted keys and certificates are accepted. • Certificates used to safeguard PAN during transmission
You are reading one control. How much of Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 have you already done?
Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 CCM-CEK-04 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 140 of 197 Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 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. 12 were rejected on the NIST SP 800-53 Rev 5 pair alone.
