Explanation

Security requirements are formally developed during the Functional Design Analysis and Planning phase, where system requirements - including security needs - are identified, analyzed, and documented before any implementation begins. Building security in at the design stage is a core principle ('security by design'). The Initiation phase (B) identifies the need for the system at a high level. Implementation (D) and Operation (A) occur after requirements have already been defined.
