Setting Up User Login Controls

You can set up login controls to make it more difficult for hackers to
access the EMX and the devices connected to it. You can arrange to
lock persons out after a specified number of failed logins, limit the
number of persons who log in using the same user name at the same
time, and force users to create strong passwords.

Enabling User Blocking

User blocking determines how many times a user can attempt to log in to
the EMX and fail authentication before the user's login is blocked.

Note that this function applies only to local authentication instead of
authentication through external AA servers.

Note: If any user blocking event occurs, you can unblock that user
manually by using the "unblock" CLI command via a serial connection.
See

Unblocking a User

(on page 321).

To enable user blocking:

1. Choose Device Settings > Security > Login Settings. The Login

Settings dialog appears.

2. Locate the User Blocking section.
