Title
AAA Services must be configured to maintain locks on user accounts until released by an administrator. (Cat II impact)
Discussion
By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the account.
Check Content
If AAA Services rely on directory services for user account management, this is not applicable and the connected directory services must perform this function. Verify AAA Services are configured to maintain locks on user accounts until released by an administrator. If AAA Services are not configured to maintain locks on user accounts until released by an administrator, this is a finding.
Fix Text
