Information

AlmaLinux OS 9 must be configured so that libuser is configured to store only encrypted representations of passwords.

GROUP ID: V-269399
RULE ID: SV-269399r1050282

Passwords must be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised.

The system must use a strong hashing algorithm to store the password.

Solution

Configure AlmaLinux OS 9 to use the SHA-512 algorithm for password hashing.

Add or change the following line in the "[defaults]" section of the "/etc/libuser.conf" file:

crypt_style = sha512
