Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An integrated circuit comprising:
multiple peripheral devices;
an alert handler comprising:
multiple alert receiver modules, each alert receiver module coupled to a peripheral device of the multiple peripheral devices;
multiple escalation timers, each respective escalation timer corresponding to a respective escalation severity of multiple escalation severities;
a controller coupled to the multiple alert receiver modules and the multiple escalation timers, the controller configured to:
classify a triggered alert received from an alert receiver module of the multiple alert receiver modules into an alert classification of multiple alert classifications based on at least one of the alert receiver module or the triggered alert; and
initiate an escalation timer of the multiple escalation timers based on the alert classification; and

multiple escalation sender modules coupled to the multiple escalation timers; and

multiple escalation handlers, each escalation handler configured to implement at least one security countermeasure,
each escalation handler of the multiple escalation handlers coupled to an escalation sender module of the multiple escalation sender modules,
at least one escalation handler of the multiple escalation handlers configured, responsive to receiving an escalate command from the alert handler, to implement the at least one security countermeasure, and
the at least one security countermeasure comprising:
erasing stored data;
disconnecting a suspect peripheral device of the multiple peripheral devices from at least one interconnect;
collapsing a power domain that includes the suspect peripheral device of the multiple peripheral devices;
resetting at least a portion of the integrated circuit; or
transitioning at least part of the integrated circuit to an invalid life cycle state.
