Abstract
Today policy specification and enforcement mechanisms are often interwoven with the industrial control processes on which the security policy is enforced. This leads to interferences and non-secure behaviour as well as increases system attack surface. This paper presents a security system architecture and a framework where the processes, policies, and enforcement are strictly separated. The security architecture follows separation and least-privilege principles. The policy framework is based on a formal language and tools to specify and generate components for the security architecture. We illustrate our approach on an technological process and present how this solution is implemented in practice where security is mixed with safety requirements such as real-time, worst case execution time and certification.
