Description
A malicious or unauthorized user could gain access to an IDPS by guessing or using methods such as dictionary attack, word list substitution, or brute force attack-all of which require multiple login attempts. By limiting the number of failed login attempts within a defined period of time, the risk of unauthorized system access via user password guessing can be mitigated.
