The System Security knowledge area focuses on the security aspects of systems that are composed of components and connections, and use software. Understanding the security of a system requires viewing it not only as a set of components and connections, but also as a complete unit in and of itself. This requires a holistic view of the system. Together with the Component Security and Connection Security KAs, the System Security KA addresses the security issues of connecting components and using them within larger systems.
The Human Securityknowledge area focuses on protecting individuals’ data and privacy in the context of organizations (i.e., as employees) and personal life, in addition to the study of human behavior as it relates to cybersecurity.
