(in versions v2 r3 through v1 r3)
Title
The BIG-IP appliance must be configured to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period. (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.
Check Content
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.
Fix Text
Configure the BIG-IP appliance to use an approved remote authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.
