Assessment Title
Rule Text
The macOS system must use only Message Authentication Codes (MACs) employing FIPS 140-2 validated cryptographic hash algorithms.
Description
Discussion Text
Unapproved mechanisms for authentication to the cryptographic module are not verified, and therefore cannot be relied upon to provide confidentiality or integrity, resulting in the compromise of DoD data.
Operating systems using encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules.
The implementation of OpenSSH that is included with macOS does not utilize a FIPS 140-2 validated cryptographic module. While the listed MACs are FIPS 140-2 approved algorithms, the module implementing them has not been validated.
By specifying a Keyed-Hash Message Authentication Code list with the order of hashes being in a "strongest to weakest" orientation, the system will automatically attempt to use the strongest hash for securing SSH connections.
Satisfies: SRG-OS-000033-GPOS-00014, SRG-OS-000120-GPOS-00061, SRG-OS-000125-GPOS-00065, SRG-OS-000250-GPOS-00093, SRG-OS-000393-GPOS-00173, SRG-OS-000394-GPOS-00174
