1. An electronic device comprising:
a printed circuit board;
a controller coupled to the printed circuit board;
a sensor;
a chipset comprising a set of integrated circuit components coupled to the printed circuit board;
a line coupled to the sensor and to the chipset;
wherein the chipset includes one or more integrated circuit components storing processor executable instructions which, when executed by one or more processors, cause the electronic device to perform operations comprising:
receiving intrusion detection configuration settings,
accessing a first cryptographic key stored at the set of integrated circuit components,
generating a cryptographic signature based on the first cryptographic key and content data representing the intrusion detection configuration settings,
storing, at the set of integrated circuit components, the cryptographic signature and the content data,
based on booting of the device:
accessing the content data stored at the set of integrated circuit components,
accessing the cryptographic signature stored at the set of integrated circuit components,
authenticating the content data using the content data and the cryptographic signature, and
based on the authenticating of the content data, loading the intrusion detection configuration settings using the content data,
receiving an interrupt signal via the line,
based on the receiving of the interrupt signal and the intrusion detection configuration settings:
determining a first time associated with the interrupt signal, and
storing, at the set of integrated circuit components, event data indicating the first time.
