DS5.8:

DS 5.8 Cryptographic Key Management

Control Objective:

Determine that policies and procedures are in place to organize the generation, change, revocation, destruction, distribution, certification, storage, entry, use and archiving of cryptographic keys to ensure the protection of keys against modification and unauthorized disclosure.

Applicability:

Sarbanes-Oxley

HIPAA

GLBA

PCI

FISMA

NIST SP 800-66

Ditscap

Control Exception

User Defined

Risk Association Control Activities:

1. PCI-3.5.1 Restrict access to keys to the fewest number of custodians necessary.

2. PCI-3.5.2 Store keys securely in the fewest possible locations and forms.

3. PCI-3.6.1 Generation of strong keys.

4. PCI-3.6.2 Secure key distribution.

5. PCI-3.6.3 Secure key storage.

6. PCI-3.6.4 Periodic key changes.

7. PCI-3.6.5 Destruction of old keys.

8. PCI-3.6.6 Split knowledge and dual control of keys (so that it requires 2 or 3 people, each knowing only their part of the key, to reconstruct the whole key).

9. PCI-3.6.7 Prevention of unauthorized substitution of keys.

10. PCI-3.6.8 Replacement of known or suspected compromised keys.

11. PCI-3.6.9 Revocation of old or invalid keys (mainly for RSA keys).

12. PCI-3.6.10 Requirement for key custodians to sign a form specifying that they understand and accept their key-custodian responsibilities.
