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.
