OL07-00-010220 - The Oracle Linux operating system must be configured so that user and group account administration utilities are configured to store only 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. Passwords encrypted with a weak algorithm are no more protected than if they are kept in plain text.Solution
Configure the operating system to store only SHA512 encrypted representations of passwords.Add or update the following line in '/etc/libuser.conf' in the [defaults] section:
crypt_style = sha512
