Explanation

In requirements engineering, functional requirements specify what a system must do while non-functional requirements specify how the system performs those functions. Security is a classic non-functional requirement at the architectural level because it defines quality attributes like confidentiality and integrity. A checking account rule represents a functional requirement at the design level because it specifies specific business logic the system must implement.
