SLEM-05-611050 - SLEM 5 must configure the Linux Pluggable Authentication Modules (PAM) to only store encrypted representations of passwords.
Information
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 Linux PAM to only store encrypted representations of passwords. All account passwords must be hashed with SHA512 encryption strength.Edit "/etc/pam.d/common-password" and edit the line containing "pam_unix.so" to contain the SHA512 keyword after third column. Remove the "nullok" option if it exists.
