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 lockout policy is configured.

1. SSH into the ProxySG console, type "enable", press "Enter".
2. Enter the appropriate password, type "config", press "Enter". 
3. Type "show security local-user-list", press "Enter". 

This should return a value of "3" for the "Max failed attempts" and "900" for the value of both the "lockout duration" and "reset interval" fields.

If Symantec ProxySG is not configured 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

The lockout policy may be configured for both SSH and Web Management Console sessions. 

1. SSH into the ProxySG console, type "enable", press "Enter".
2. Enter the appropriate password, type "config", press "Enter". 
3. Type "security local-user-list edit local_user_database", press "Enter". 
4. Type "lockout-duration 900", type "max-failed-attempts 3", press "Enter".
