SRG-APP-000170-AAA-000500
(in versions v2 r2 through v2 r1)
Title
AAA Services must be configured to require the change of at least eight of the total number of characters when passwords are changed. (Cat II impact)
Discussion
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Use of a complex password helps to increase the time and resources required to compromise the password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised.
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. Where passwords are used, verify AAA Services are configured to require the change of at least eight of the total number of characters when passwords are changed. This requirement may be verified by demonstration or configuration review. If AAA Services are not configured to require the change of at least eight of the total number of characters when passwords are changed, this is a finding.
Fix Text
Configure AAA Services to require the change of at least eight of the total number of characters when passwords are changed. Note: The best practice would be to require that all characters must be changed with each password change, especially for privileged accounts.
