This seminar will provide an overview of how Information Security (AKA Cyber Security, AKA INFOSEC) engineering, requirements analysis and security policies and other activities fit into the overall life cycle of an IT system. We will define an INFOSEC systems engineering methodology using industry best practices and we will define the major steps or key activities in that systems engineering methodology. We will also discuss what the role of Information Systems Security Engineering and the Systems Security Engineers should be in the Life Cycle processes.
