AU-9(3): Cryptographic Protection

Implement cryptographic mechanisms to protect the integrity of audit information and audit tools.


Not applicable - Not applicable
Planned - The implementation is planned
In progress - The implementation is currently in progress
Partially implemented - The control is partially implemented
Implemented - The control is fully implemented
Alternative implementation - There is an alternative implementation in place (e.g., shared responsibility or inherited implementation)
Description

Cryptographic mechanisms used for protecting the integrity of audit information include signed hash functions using asymmetric cryptography. This enables the distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash.
