Abstract

When we deal with the risks associated with the industrial control systems (ICS), we have to frame them into a more general problem: the risk management (RM) techniques. In fact, organizations always manage risk in order to fulfill their (business) tasks and objectives, and we speak here about economic and financial risk, personnel physical risk, equipment failure, ICS malfunctioning and so on. Normally, such organizations evaluate their business risks, determining how to deal with them in the frame of their priorities, taking into account internal and external constraints. In fact, RM is regarded as an interactive process, this being in permanent connection with usual (technical) processes. At the same time, when using ICS it is normal to have some sort of good engineering practices and safety compulsory rules. These safety assessments are formulated as regulatory requirements, this being a part of the official operating procedures. This is why we consider that RM (in general) and ICS associated risks (in particular) may be regarded as an added/complimentary dimension to any plant operation. Based on a comprehensible literature study, this chapter will concentrate on how ICS associated risks (usually formulated at the global system information level) are identified, expressed and (if possible) quantified. At the same time, like any other RM activity, we will indicate that dealing with these risks usually impacts the other system levels. It is our intention to show how extending the concepts here emphasized (for the control level) provides ICS-specific rules to be integrated in specific system/plant operating procedures. Finally, some conclusions will be presented.
