Title

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

Fix Text
