Title
Ubuntu 22.04 LTS must encrypt all stored passwords with a FIPS 140-3-approved cryptographic hashing algorithm.
Control
Verify that the shadow password suite configuration is set to encrypt passwords with a FIPS 140-3 approved cryptographic hashing algorithm by using the following command: $ grep -i '^\s*encrypt_method' /etc/login.defs ENCRYPT_METHOD SHA512 If "ENCRYPT_METHOD" does not equal SHA512 or greater, is commented out, or is missing, this is a finding.
Discussion
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.
