What is the focus of continuous monitoring in security as per DSAC Annex B?

Continuous monitoring in security primarily emphasizes the ongoing assessment and enhancement of security controls, practices, and effectiveness for an organization. This process allows organizations to adapt to changes in both internal and external environments, especially in terms of emerging threats and vulnerabilities.

The improvement of key performance indicators relates directly to how effectively security measures are implemented and maintained over time. By continuously monitoring these indicators, organizations can make informed decisions regarding the necessity of adjustments or improvements to their security posture. This approach ensures that the organization can quickly identify and respond to incidents, thereby reducing potential risks.

The other options, while potentially relevant to general business operations, do not capture the essence of continuous monitoring specific to security needs. For instance, cost reduction strategies, enhancements to communication systems, and expansion of business services do not inherently focus on safeguarding information and assets, which is the central goal of continuous monitoring in security contexts.
