During which phase of the SDLC should an organization consider the 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, as well as during the development and acquisition phases of the System Development Life Cycle (SDLC), is essential for building a secure system from the ground up. In the initiation phase, the organization's objectives, potential risks, and security needs can be identified to ensure that security is prioritized from the very beginning. During the development and acquisition phases, specific measures can be integrated into the software or systems being created or procured. At this stage, security requirements can include both technical specifications for security controls and policies to address potential threats and vulnerabilities. Incorporating security considerations early allows organizations to design systems with security in mind rather than tacking it on as an afterthought later in the process. This proactive approach helps to minimize security flaws and reduces costs associated with later remediation efforts. The other phases, such as implementation, operation/maintenance, and system disposal, while they include important security activities, are generally not the appropriate time to initially consider security requirements. By that point, the core system and architecture are already set, and changes could be more challenging and costly to implement effectively. Therefore, early consideration of security requirements is crucial in setting the foundation for a secure system throughout its lifecycle.
