CCI(s)

• CCI-004062 - For password-based authentication, store passwords using an approved salted key derivation function, preferably using a keyed hash.

Fix Recommendation

Configure Red Hat Enterprise Linux 9 to use 5000 hashing rounds for hashing passwords.

Add or modify the following line in "/etc/pam.d/system-auth" and set "rounds" to "5000".

password sufficient pam_unix.so sha512 rounds=5000'

Check Contents

Verify the number of rounds for the password hashing algorithm is configured using the following command:

$ sudo grep rounds /etc/pam.d/system-auth

password sufficient pam_unix.so sha512 rounds=5000

If a matching line is not returned or "rounds" is less than "5000", this is a finding.
