Time-based intrusion detection in cyber-physical systems
Christopher J. Zimmer, Balasubramanya Bhat, Frank Mueller, Sibin Mohan · 2010
Embedded systems, particularly real-time systems with temporal constraints, are increasingly deployed in every day life. Such systems that interact with the physical world are also referred to as cyber-physical systems (CPS). These systems commonly find use in critical infrastructure from transportation to health care. While security in CPS-based real-time embedded systems has been an afterthought, it is becoming a critical issue as these systems are increasingly networked and inter-dependent. The advancement in their functionality has resulted in more conspicuous interfaces that may be exploited to attack them.
