Accountability involves the identification of those that have access to, or control of, cryptographic keys throughout their lifecycles. Accountability can be an effective tool to help prevent key compromises and to reduce the impact of compromises once they are detected. Although it is preferred that no humans are able to view keys, as a minimum, the key management system should account for all individuals who are able to view plaintext cryptographic keys. In addition, more sophisticated key-management systems may account for all individuals authorized to access or control any cryptographic keys, whether in plaintext or ciphertext form. Accountability provides three significant advantages It aids in the determination of when the compromise could have occurred and what individuals could have been involved. It tends to protect against compromise, because individuals with access to the key know that their access to the key is known. It is very useful in recovering from a detected key compromise to know where the key was used and what data or other keys were protected by the compromised key. Certain principles have been found to be useful in enforcing the accountability of cryptographic keys. These principles might not apply to all systems or all types of keys. Some of the principles that apply to long-term keys controlled by humans include Uniquely identifying keys. Identifying the key user. Identifying the dates and times of key use, along with the data that is protected. Identifying other keys that are protected by a symmetric or private key. Two types of audit should be performed on key management systems The security plan and the procedures that are developed to support the plan should be periodically audited to ensure that they continue to support the Key Management Policy (NIST SP 800-57 Part 2). The protective mechanisms employed should be periodically reassessed with respect to the level of security that they provide and are expected to provide in the future, and that the mechanisms correctly and effectively support the appropriate policies. New technology developments and attacks should be taken into consideration. On a more frequent basis, the actions of the humans that use, operate and maintain the system should be reviewed to verify that the humans continue to follow established security procedures. … Attribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
