Overview

Finding ID Version Rule ID IA Controls Severity

Description
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.

Verify the password history file exists on the SUSE operating system.

Check that the password history file exists with the following command:

# ls -al /etc/security/opasswd

-rw------- 1 root root 7 Dec 13 17:21 /etc/security/opasswd

If "/etc/security/opasswd" does not exist, this is a finding.
