Description
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the account. This applies to network elements that have the concept of a user account (e.g., VPN, ALG, and proxy) as well as devices that can control traffic flow based on access authorizations (firewalls, IDPS).
