Abstract
In one embodiment, an apparatus comprises a processing circuitry to detect an occurrence of at least one of a single-stepping event or a zero-stepping event in an execution thread on an architecturally protected enclave and in response to the occurrence, implement at least one mitigation process to inhibit further occurrences of the at least one of a single-stepping event or a zero-stepping event in the architecturally protected enclave.
