Verify the BIG-IP appliance is configured to use a remote authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.

Navigate to the BIG-IP System manager >> System >> Users >> Authentication.

Verify "Authentication: User Directory" is configured for an approved remote authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.

If the BIG-IP appliance is not configure to use a remote authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period, this is a finding.
