During which phase of the SDLC should the organization consider security requirements?

• A. Initiation Phase/Development/Acquisition Phase
• B. Implementation Phase
• C. Operation/Maintenance Phase
• D. System Disposal Phase

Answer: (A)

Considering security requirements during the initiation phase and the development/acquisition phase of the System Development Life Cycle (SDLC) is crucial because this is when the foundation for security is laid. In these early stages, organizations are defining the system's purpose, needs, and scope, which inherently includes identifying potential security risks and compliance needs related to sensitive data and resources. Incorporating security requirements at this stage helps to identify vulnerabilities early, allowing for the integration of appropriate security controls and standards throughout the development process. This proactive approach ensures that security is not an afterthought but rather an integral component of the system design, which can prevent costly fixes and potential security breaches later in the lifecycle. By addressing security concerns upfront, the organization can align its security strategy with business objectives, ensuring that as the system evolves, all components are designed to protect against threats effectively. This reduces the risk of rework and increases the likelihood of the system meeting compliance mandates when it transitions to later phases, such as implementation and operation.
