At which of the basic phases of the System Development Life Cycle are security requirements formalized?
Correct Answer: D
Explanation/Reference:
Explanation:
Requirements, including security requirements, are formalized in the Functional Requirements Definition phase.
Incorrect Answers:
A: Disposal activities need to ensure that an orderly termination of the system takes place and that all necessary data are preserved. Security requirements are not formalized at the disposal phase.
B: Within the Systems Development Life Cycle (DSLC) model the design phase, also known as the System Design Specifications phase, transforms requirements, including the security requirements, into a complete System Design Document.
C: In the implementation phase the system is implemented into a product production environment. The security requirements have already been developed long before this phase.
