The Component Security knowledge area focuses on the design, procurement, testing, analysis and maintenance of components integrated into larger systems. The security of a system depends, in part, on the security of its components. The security of a component depends on how it is designed, fabricated, procured, tested, connected to other components, used and maintained. This knowledge area is primarily concerned with the security aspects of the design, fabrication, procurement, testing and analysis of components. Together with the Connection Security and System Security KAs, the Component Security KA addresses the security issues of connecting components and using them within larger systems.
