An IT administrator uses the Remote Agent Presence Interface to register applications that are required by IT policy to run on client platforms, such as Anti-virus, firewall, or software installation tracking programs. ISVs develop these applications incorporating calls to the Local Agent Presence Interface. When the application starts executing, it sends heartbeat messages to Intel AMT. If the application fails to start or stops running due to a virus interrupting its operation or due to a user shutting it down, Intel AMT detects the problem and can send an alert to a management console using the Event Management Interface. A System Defense policy, created with the Circuit Breaker Interface can limit workstation access to the network until the interrupted application is operational.
