Modifying the User Watchlist
A Watchlist is a list of VIPs, executives, and devices known to be problematic that are monitored for authentication failures. Policy Manager collects all user authentication status. When Policy Manager finds a user defined in the Watchlist that both fails to authenticate and also matches the Watchlist triggers (severity, threshold, and interval), an alert notification is sent to the notification list via email or to mobile devices via SMS Short Message Service. SMS refers to short text messages (up to 140 characters) sent and received through mobile phones.. This allows the authentication failure to be resolved proactively before the problem is reported by the user. sThe Watchlist generates an alert only when an unsuccessful authentication for a specific device occurs.
