Inspect the "password" section of "/etc/pam.d/system-auth" and ensure that the "pam_unix.so" module includes the argument "sha512". $ grep sha512 /etc/pam.d/system-auth" If it does not, this is a finding. |

In "/etc/pam.d/system-auth", the "password" section of the file controls which PAM modules execute during a password change. Set the "pam_unix.so" module in the "password" section to include the argument "sha512", as shown below: password sufficient pam_unix.so sha512 [other arguments...] This will help ensure when local users change their passwords, hashes for the new passwords will be generated using the SHA-512 algorithm. This is the default. Note that any updates made to "/etc/pam.d/system-auth" will be overwritten by the "authconfig" program. The "authconfig" program should not be used. |
