Information

The SUSE operating system must configure the Linux Pluggable Authentication Modules (PAM) to only store encrypted representations of passwords.

GROUP ID: V-234886
RULE ID: SV-234886r1009625

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 the SUSE operating system 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.
