US Patent 11836064 Computing device monitoring

A method of monitoring an operating state of a computing device includes running a system agent on the computing device. An introduced process is executed on the computing device, and a captured parameter relating to at least one of the system agent and the introduced process is captured. The captured parameter is compared to at least one pre-determined parameter. Where the captured parameter differs from the pre-determined parameter by more than a pre-determined threshold, a signal indicative of a change in operating state of the computing device is output.
