Linux RHEL-10-600740

DISA STIG RHEL-10-600740 (CAT I): RHEL 10 must be configured to use the shadow file to store only encrypted representations of passwords.

DISA STIG recommends

RHEL-10-600740 CAT I

RHEL 10 must be configured to use the shadow file to store only encrypted representations of passwords.

NIST SP 800-53: IA-5(1)

Check

Verify RHEL 10 is configured so that the shadow file stores only encrypted representations of passwords with a hash value of SHA512 with the following command: $ sudo grep -i encrypt_method /etc/login.defs ENCRYPT_METHOD SHA512 If "ENCRYPT_METHOD" does not have a value of "SHA512", or the line is commented out, this is a finding.

Fix

Configure RHEL 10 to store only SHA512 encrypted representations of passwords. Add or update the following line in the "/etc/login.defs" file: ENCRYPT_METHOD SHA512
