Abstract
A system and method for identifying compromised systems, even where cyber security measures are in place, continuously monitors system parameters against a set of predefined thresholds. If the system violates those thresholds, either instantaneously or over a period of time, the system determines that unknown processes are using the system; those processes may be unauthorized processes loaded via a successful spoof attack. The system may monitor CPU usage, power usage, temperature, memory access, data storage access, data transmission rates, etc. The system may execute some remedial action when unauthorized processes are suspected.
Claims20
A computer apparatus comprising:
- a monitored processor;
- and
- at least one monitoring processor configured to:
- continuously receive one or more parameter values, each corresponding to an operating parameter of the monitored processor;
- compare the one or more parameter values to a corresponding threshold;
- determine if the one or more parameter values exceeds the corresponding threshold;
- and
- produce a risk assessment.
