CPS-MT: A Real-Time Cyber-Physical System Monitoring Tool for Security Research

Abstract

Monitoring systems are essential to understand and control the behaviour of systems and networks. Cyber-physical systems (CPS) are particularly delicate under that perspective since they involve real-time constraints and physical phenomena that are not usually considered in common IT solutions. Therefore, there is a need for publicly available monitoring tools able to contemplate these aspects. In this poster/demo, we present our initiative, called CPS-MT, towards a versatile, real-time CPS monitoring tool, with a particular focus on security research. We first present its architecture and main components, followed by a MiniCPS-based case study. We also describe a performance analysis and preliminary results. During the demo, we will discuss CPS-MT's capabilities and limitations for security applications.

Defining a set of metrics for detecting attacks at FSC

“…Идея обработки данных состоит в том, что строится нормальное распределение случайно величины, значения которых получены для некоторого количества вре-менных участков. Далее, после того как нормальное распределение для заданного количества случайных величин построено и накоплена информация о некотором количестве новых временных участков, на которых зафиксировано значение случайно величины, необходимо построить новую функцию распределения вероятностей [12]. Для этого необходимо определить количество участков, через которое функция нормального распределения будет обновляться.…”

Analysing Mission-critical Cyber-physical Systems with AND/OR Graphs and MaxSAT

“…While useful in many types of scenarios [69], most of them are focused on OR-only graph-based models for IT networks and do not cover AND/OR semantics. Other important approaches targeting cyber-physical systems include probabilistic model checking and formal methods [30,42,73,78], security metrics and graph-based methods [34,61,70,72], system design analysis [19], real-time monitoring [12,38], structural controllability aspects [3,52,58,60], among others. The focus of this work is on the identification of CPS components that are most likely to jeopardise the system's mission.…”

Trustworthy Inter-connected Cyber-Physical Systems

“…Therefore, there is a need for publicly available monitoring tools able to contemplate these aspects. We have developed an approach, called CPS-MT [1], which is a proof-of-concept of a versatile, real-time CPS monitoring tool, with a particular focus on security research.…”
