Vulnerability discussion

Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed at specific intervals. One method of minimizing this risk is to use complex passwords and periodically change them. If the application does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the system and/or application passwords could be compromised. This requirement does not include emergency administration accounts which are meant for access to the application in case of failure. These accounts are not required to have maximum password lifetime restrictions.

Check content

If the AAA Service relies on directory services for user account management this is not applicable and the connected directory services must perform this function. Verify the AAA Service is configured to enforce a 60-day maximum password lifetime restriction. Additionally, the AAA Service must force password change upon the first logon after the expiration of the 60 days. If the AAA Service is not configured to enforce a 60-day maximum password lifetime restriction, this is a finding.

Fix text

Configure the AAA Service to enforce a 60-day maximum password lifetime restriction. Additionally, configure the AAA Service to force password change upon the first logon after the expiration of the 60 days.
