Safe & sec case patterns

Abstract

Many industrial sectors, which manufacture safety intensive systems e.g., automotive, railway, etc., now face technical challenges on how to integrate and harmonize critical issues on safety in addition to security for their systems. In this paper, we will explore a new way of reconciling those issues in an argument form, which we call Safe & Sec (Safety and Security) case patterns. They are derived from process patterns identified from our literature survey on research and standards. Safe & Sec case patterns in this paper will provide practitioners a wide perspective and baseline on how they could provide an assurance framework for their safety intensive systems with security focus.
