| [PCI-DSS] Requirement 3: Protect stored cardholder data Encryption is a critical component of cardholder data protection. If an intruder circumvents other network security controls and gains access to encrypted data, without the proper cryptographic keys, the data is unreadable and unusable to that person. Other effective methods of protecting stored data should be considered as potential risk mitigation opportunities. For example, methods for minimizing risk include not storing cardholder data unless absolutely necessary, truncating cardholder data if full PAN is not needed, and not sending PAN in unencrypted e-mails. |

[PCI-DSS] 3.5.1 Restrict access to cryptographic keys to the fewest number of custodians necessary.
3.5.1 Examine user access lists to verify that access to keys is restricted to very few custodians.
