How does Shadow IT visibility help in policy construction?

The correct choice highlights the importance of assigning risk scores to applications, which can significantly influence policy construction. In an environment where shadow IT is prevalent, organizations often do not have visibility into what applications are being used by employees. By utilizing a risk scoring system, organizations can identify which applications pose potential threats based on various factors such as data sensitivity, compliance issues, and known vulnerabilities.

When applications with a risk score above a certain threshold, like 4 in this case, are auto-blocked, it allows the organization to proactively manage and secure its network environment. This policy approach ensures that high-risk applications are curtailed, minimizing the potential for data breaches or other security incidents. It enables a risk-based framework that aligns security measures with actual usage patterns and threats, making the policy more effective.

The other choices do not provide constructive methodologies for managing shadow IT. Ignoring all applications would leave the organization vulnerable, while allowing all applications to be used freely ignores the inherent risks. Simplifying user access to applications may improve usability, but without a focus on security, it can lead to increased exposure to threats. Thus, focusing on a risk scoring system is essential for effective policy construction.
