A Novel System-Theoretic Matrix-Based Approach to Analysing Safety and Security of Cyber-Physical Systems

Aligning Cyber-Physical System Safety and Security

Safety and security are two key properties of Cyber-Physical Systems (CPS). Safety is aimed at protecting the systems from accidental failures in order to avoid hazards, while security is focused on protecting the systems from intentional attacks. They share identical goals – protecting CPS from failing. When aligned within a CPS, safety and security work well together in providing a solid foun...

Cyber Safety: A Systems Theory Approach to Managing Cyber Security Risks – Applied to TJX Cyber Attack

To manage security risks more effectively in today’s complex and dynamic cyber environment, a new way of thinking is needed to complement traditional approaches. In this paper we propose a new approach for managing cyber security risks, based on a model for accident analysis used in the Systems Safety field, called System-Theoretic Accident Model and Processes (STAMP). We have adapted and appli...

Cyber Safety: A Systems Thinking and Systems Theory Approach to Managing Cyber Security Risks

If we are to manage security risks more effectively in today’s complex and dynamic cyber environment, then a new way of thinking is needed to complement traditional approaches. According to Symantec’s 2014 Internet Security Threat Report, in 2012 more than ten million identities that included real names, dates of birth, and social security were exposed by a single breach. In 2013 there were eig...
