Assessment Title

Rule Text

Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors.

Description

Discussion Text

Cryptographic hashes provide quick password authentication while not actually storing the password.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

The root role is required.

Configure the system to disallow the use of UNIX encryption and enable SHA256 as the default encryption hash.

# pfedit /etc/security/policy.conf

Check that the following lines exist and are not commented out:

CRYPT_DEFAULT=6
CRYPT_ALGORITHMS_ALLOW=5,6
