Title

Protect Audit Integrity with Cryptographic Mechanisms

Control

The technology supports this requirement and cannot be configured to be out of compliance. The technology inherently meets this requirement.

Discussion

The information system _IS_ configured to implement cryptographic mechanisms to protect the integrity of audit information and audit tools.

The Apple T2 Security Chip includes a dedicated Advanced Encryption Standard (AES) crypto engine built into the direct memory access (DMA) path between the flash storage and main system memory, which powers line-speed encrypted storage with FileVault and makes internal volume highly efficient.

NOTE: This will only apply to a Mac that includes a T2 security chip.

Fix
