SLEM-05-611075 - SLEM 5 must employ a password history file.

Information

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Solution

Configure SLEM 5 to create the password history file with the following commands:

Create the file:
> sudo touch /etc/security/opasswd

Set ownership permissions:
> sudo chown root:root /etc/security/opasswd

Set access permissions:
> sudo chmod 0600 /etc/security/opasswd
