This document discusses the importance of balancing usability and security in user interface design for cybersecurity systems. It proposes a framework with five principles for user interface design for cybersecurity: clarity, consistency, feedback, accessibility, and security. The framework aims to provide users with clear understanding of security features, alerts for threats, and tools to keep systems secure, while still making systems easy for users to access. The next chapter will examine challenges of this balance between usability and security.
