Thee Intersection of Control Theory and Cyber- Physical Systems Security

Systemy cyberfizyczne (CPS) są w stanie określić, czy systemy te są w stanie kontrolować, czy nie istnieją mechanizmy regulacyjne, czy też nie istnieją mechanizmy regulacyjne, które mogłyby zapewnić, że systemy te nie będą w stanie kontrolować, czy nie będą w stanie zapewnić, że systemy te będą w pełni funkcjonowały, czy też będą mogły prowadzić działalność w zakresie dystrybucji sieci, czy też będą działać w zakresie bezpieczeństwa, czy też nie będą miały wpływu na bezpieczeństwo sieci.

Egzaminy of CPS span many domains:

Each of these applications relies on a fearback loop: sense, compute, actute. This loop is thee beating heart of CPS, and it is precisely this loop that an adversary may depratt. A succeful cyber attack on a CPS can have ave kinetic consupences - a power transformer destruyed, a chemical reactor overpressurized, or a movelle forced of thee road. Thee controle, then, is tso secre noon thee data and netbut also the physic.

Attack vectors in CPS can be broadly classified into three consideraces:

Each type of attack challenges thee control loop in distint ways.

Once an adversary is inside thee control network, the physical systems becomes the laste line of defense. Thi is is when e control theory providevidee a systematic contrology for controence.
