During which phase of an IT system life cycle are security requirements developed?
Correct Answer: C
Explanation/Reference:
Within the Systems Development Life Cycle (DSLC) model the design phase, also known as the security requirement phase, transforms requirements, including the security requirements, into a complete System Design Document.
Incorrect Answers:
A: The operation phase describes tasks to operate in a production environment, and is not concerned with development of security requirements.
B: The initiation phase starts when a sponsor identifies a need or an opportunity. During this phase a Concept Proposal, but no security requirements, is created.
D: In the implementation phase the system is implemented into a product production environment. The security requirements have already been developed long before this phase.
