Managing Your Risk

How security establishes a suitable environment for safety. The frequent news stories relating to cyber breaches have led to a global increase in sensitivity toward the topic of security in all industries. Process safety practitioners are increasingly concerned with the potential impact of security threats on implemented safety instrumented functions (SIF).   The process automation industries have traditionally employed independent protection layers (such as BPCS and SIS) for safety so it is perhaps not surprising that there is a trend toward justifying the adoption of physical separation in order to potentially improve the security of an installation.   This paper outlines an approach to implementing cyber security in an integrated BPCS and SIS scenario and gives an overview of how security and functional safety can be addressed more effectively.
