SLEM-05-611080 - SLEM 5 must employ FIPS 140-2/140-3-approved cryptographic hashing algorithms for system authentication.

Information

The system must use a strong hashing algorithm to store the password. The system must use a sufficient number of hashing rounds to ensure the required level of entropy.

Passwords need to 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.

Solution

Configure SLEM 5 to encrypt all stored passwords with FIPS 140-2/140-3-approved cryptographic hash.

Add or modify the following line in the "/etc/login.defs" file:

ENCRYPT_METHOD SHA512

Lock all interactive user accounts not using SHA512 hashing until the passwords can be regenerated.
