This paper explores the importance and necessity of information technology (IT) and telecommunications security (combined, these activities are referred to as INFOSEC) in an ever more interconnected world. A review of the current state of affairs, some important organizations, privacy, regulatory issues, threats, protections, and tools is undertaken, and a plan for proceeding in this complex arena is presented. A detailed Security Hierarchy Chart is presented at the end of the paper that compiles in a single, easy to use repository threats, attacks, tools and products by segment and layer.
