1. A single-chip system, comprising:
a plurality of computing units;
at least one input/output unit;
a memory unit;
an input/output control unit configured to coordinate communication between the plurality of computing units and the at least one input/output unit; and
an attack detection unit communicatively connected to the input/output control unit via a first hardware signal connection, wherein the attack detection unit is configured to:
evaluate a first input signal received from the input/output control unit for determining infringement of one or more rules based on a set of attack detection rules, wherein the attack detection rules comprise restrictions to the memory unit;
based on the evaluation of the first input signal and upon determination of a first infringement of the one or more rules, log the first infringement of the one or more rules;
based on the evaluation of the first input signal and upon determination of infringement of the one or more rules, respond to the first infringement of the one or more rules with at least one preconfigured measure;
evaluate a second input signal received from at least one component of the single-chip system via a second hardware signal connection for determining a second infringement of the one or more rules based on the set of attack detection rules;
based on the evaluation of the second input signal and upon determination of infringement of the one or more rules, log the second infringement of the one or more rules; and
based on the evaluation of the second input signal and upon determination of infringement of the one or more rules, respond to the second infringement of the one or more rules with the at least one preconfigured measure,
wherein the at least one component of the single-chip system comprises a memory access control unit and/or the memory unit.
