Which phase of the Risk Management Lifecycle demands significant time and effort for security control implementation?

The phase of the Risk Management Lifecycle that demands significant time and effort for security control implementation is the Control phase. During this phase, organizations focus on the actual deployment of security measures, which includes the design, configuration, and integration of controls that mitigate identified risks.

Implementing security controls is often complex and can involve various tasks such as selecting appropriate technologies, configuring systems to ensure they work effectively, and ensuring that personnel are trained to use the controls competently. This phase often requires collaboration across different teams and departments to ensure that the controls fit within the existing architecture and meet the organization's security requirements. The time and resources devoted to this phase are crucial for establishing a robust security posture, thus making it the most intensive phase regarding effort and commitment.

While Identify, Assess, and Review phases are also important, they focus on understanding risks, evaluating potential impacts, and reassessing controls over time rather than the intensive operational tasks associated specifically with implementing the controls themselves.
