Security intrusion detection and response

摘要

A system comprises an enclosure, host logic contained in the enclosure, and intrusion security logic also contained in the enclosure. The intrusion security logic is coupled to the host logic and configured to detect a security intrusion to the system and to respond to a security intrusion with a user-configurable trigger event. The intrusion security logic implements at least two tamper blocks, each tamper block configured to monitor one more input signals and initiate a trigger event when a security breach of the enclosure is detected. At least one of the tamper blocks comprises a state machine whose operation is controlled by way of user-programmable registers.

1. A system, comprising:
an enclosure; host logic contained in said enclosure; intrusion security logic also contained in said enclosure, said intrusion security logic coupled to said host logic and configured to detect an intrusion security to said system and to respond to said security intrusion with a user-configurable trigger event,
the user-configured trigger event including at least:
a) which types of input stimuli correlated to a physical condition of a security intrusion of the enclosure are to be monitored for detection of a security breach, andb) what sort of response the intrusion security logic should perform upon detection of the security breach, wherein said intrusion security logic implements at least two tamper blocks, each tamper block configured to: monitor one more input signals and initiate a trigger event when a security breach of the enclosure is detected correlated to said physical condition, and wherein at least one of said tamper blocks comprises a state machine whose operation is controlled by way of user-programmable registers.
