For local accounts created on the device, the Juniper SRX Services Gateway must enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.

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.

Juniper SRX is unable to comply with the 15-minute time period part of this control.

Verify the number of unsuccessful logon attempts is set to 3.

If the number of unsuccessful logon attempts is not set to 3, this is a finding.

Configure the number of unsuccessful logon attempts for all login account, globally.
