During which phase of the SDLC are Security Reauthorizations conducted?

• A. Initiation
• B. Development/Acquisition
• C. Implementation
• D. Operations/Maintenance

Answer: (D)

Security Reauthorizations are primarily conducted during the Operations/Maintenance phase of the Software Development Life Cycle (SDLC). This phase focuses on the ongoing management and maintenance of the system after it has been implemented. It is during this period that continuous monitoring and risk assessment occur, necessitating the reauthorization of the system to ensure it still meets the required security standards. Reauthorizations are vital for confirming that the system still complies with the relevant policies, standards, and regulations, especially as threats, vulnerabilities, and business environments evolve over time. This ongoing assessment is crucial to maintaining the system's security posture and ensuring that any necessary updates or changes are documented and managed properly. In contrast, the other phases of the SDLC do not typically involve reauthorization. For example, the Initiation phase is focused on the initial planning and resource allocation, while the Development/Acquisition phase involves building or obtaining the system. The Implementation phase is primarily concerned with deploying the system into a live environment. Thus, security reauthorizations are distinctly relevant to the Operations/Maintenance phase when evaluating the security posture of an already deployed system.
