Which phase of the SDLC is critical for identifying design flaws?

• A. Implementation
• B. Design
• C. Testing
• D. Deployment

Answer: (B)

The design phase of the Software Development Life Cycle (SDLC) is crucial for identifying design flaws because it is during this stage that the architectural and detailed design of the system is developed. In this phase, key decisions about how the software will function are made, including the overall structure, data flow, and interactions between various components. By thoroughly reviewing designs and developing prototypes, teams can identify potential vulnerabilities and flaws early in the process. This proactive approach allows developers to make necessary adjustments before proceeding to later phases, where fixing such issues can become more costly and complex. Moreover, security controls can be incorporated into the design, ensuring that they are woven into the fabric of the application rather than added as an afterthought during implementation or testing phases. Addressing design flaws at this stage can significantly improve the security posture and effectiveness of the software, as it sets the foundation for a secure system architecture. Thus, the design phase holds a pivotal role in ensuring a robust and secure end product.
