Abstract : Transient attacks manipulate speculative execution to alter the control flow path in an application program and modify microarchitectural state. These state changes are not captured by the existing Instruction Set Architectures (ISAs). In this paper, we propose a novel OS-level detection-based mitigation mechanism, called Transit-Guard, that uses machine learning and real-time behavioral data of concurrent processes to detect and subsequently mitigate these attacks at run-time.
