Description
Administrators need to be aware of activity that occurs regarding their network device management account. Providing administrators with information regarding the number of unsuccessful attempts made to login to their account allows them to determine if any unauthorized activity has occurred. Without this information, the administrator may not be aware that unauthorized activity has occurred. This incorporates all methods of login, including, but not limited to, SSH, HTTP, HTTPS, and physical connectivity.
