“…This is a useful technique in re-discovery of topology in large and complex SCADA systems, where a traditional network scanner can cause PLC failure in the form of a DOS attack. Hale (1988). Their solution was tested using a Siemens S7-1200 PLC with the Arduino connected to the Profinet interface.…”

Industrial Control Systems (ICS) and SCADA (Supervisory Control and Data Acquisition) systems are typically used in industries such as electricity generation and supply, gas supply, logistics, manufacturing and hospitals and are considered critical national infrastructure. The evolution of these systems from isolated environments into internet connected ones, in combination with their long service life and real-time nature have raised severe security concerns in the event of a cyber-attack. In this paper, we review the current literature surrounding the threats, vulnerabilities, exploits and existing approaches to securing vulnerable SCADA systems. We then focus specifically on the development of a distributed online runtime monitor to detect violations of safety properties. We conclude with suggestions for further research needed to progress the state of the art in the area of distributed online runtime verification of SCADA systems.

“…In this section we revisit the standard semantics of Interval Temporal Logic [15] (albeit restricted to the finite case) ITL is the underlying formalism of the AnaTempura Runtime Verification Framework [29] which uses an executable subset of ITL called Tempura developed by [40,41].…”

Industrial Control Systems (ICS) are widely deployed in nation's critical national infrastructures such as utilities, transport, banking and health-care. Whilst Supervisory Control and Data Acquisition (SCADA) systems are commonly deployed to monitor real-time data and operations taking place in the ICS they are typically not equipped to monitor the functional behaviour of individual components. In this paper (This paper expands on an earlier position paper presented at the International Symposium for Industrial Control System and SCADA Cyber Security Research 2014), we are presenting a runtime-monitoring technology that provides assurances of the functional behaviour of ICS components and demonstrates how this can be used to provide additional protection of the ICS against cyber attacks similar to the well-known Stuxnet attack.

“…The model can be implemented straightforwardly from its semantics using AnaTempura [10], [5], resulting in the following code for example 1: Here three events are modelled for the service, and an example trace is generated by the function evtmodel(Evts). AnaTempura can be run in a run-time verification mode and could receive these events from an external program.…”

Abstract-The Internet of Things, large scale sensor networks or even in social media, are now well established and their use is growing daily. Usage scenarios in these fields highlight the requirement to process, procure, and provide information with almost zero latency. This work is introducing new concepts for enabling fast communication by limiting information flow through filtering concepts combined with data processing techniques adopted from complex event processing. Specifically we introduce a novel mediation services architecture using filter policies to reduce latency. The filter policies define when and what data services need to provide to the mediator and thus save on bandwidth. The filter policies describe temporal conditions between two events removing the need to keep a complete history while still allowing temporal reasoning. Promising experimental results highlight the advantages to be gained from the approach.
