Which phase of the SDLC includes the implementation of security controls?

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

Answer: (C)

The correct answer focuses on the Implementation phase of the Software Development Life Cycle (SDLC), where security controls are put into place. During this phase, the actual deployment of the system occurs, and it is crucial to ensure that all security measures are applied to safeguard data and protect the system from vulnerabilities. In the Implementation phase, security controls are integrated into the system's architecture. This involves not just applying security technologies but also configuring them to ensure they operate correctly and effectively mitigate risks identified in earlier phases. Additionally, employee training and awareness programs may also be established at this point to manage human factors in security. This phase is critical because it translates theoretical security plans into practical measures. Without proper implementation of these controls at this stage, the system may be exposed to risks, which could potentially lead to data breaches and other security incidents. Other phases, such as Initiation, Development/Acquisition, and Operations/Maintenance, do involve considerations of security but do not specifically focus on the applied implementation of security controls to the same extent as the Implementation phase.
