Mô tả

The commands below change password encryption from md5 to sha512 (a much stronger hashing algorithm). All existing accounts will need to perform a password change to upgrade the stored hashes to the new algorithm. Note: • These changes only apply to accounts configured on the local system. • Additional module options may be set, recommendation only covers those listed here. Audit: Passes when pam_unix.so on the password stack of /etc/pam.d/system-auth and /etc/pam.d/system-password uses the sha512 option.

Edit the /etc/pam.d/system-password and /etc/pam.d/system-auth files to include sha512 option and remove the md5 option for pam_unix.so: password sufficient pam_unix.so sha512 Note: • Any system accounts that need to be expired should be carefully done separately by the system administrator to prevent any potential problems. • If it is determined that the password algorithm being used is not SHA-512, once it is changed, it is recommended that all user ID's be immediately expired and forced to change their passwords on next login, In accordance with local site policies.
