Which of the following is an example of a key metric a security manager might track?

Tracking the time to resolve vulnerabilities is a key metric for a security manager because it directly relates to the effectiveness of the organization's vulnerability management process. This metric provides insights into how quickly the security team can identify, assess, and remediate vulnerabilities, which is crucial for maintaining a robust security posture.

A shorter time to resolution often indicates an efficient process and the capability to address security threats proactively, reducing the potential window of exposure for the organization. This metric can also help in understanding the workload and resource allocation of the security team, ensuring that vulnerabilities do not linger and that systems are kept secure.

While other metrics, such as the number of successful logins, the amount of data stored, and vendor performance ratings, can provide useful information about different aspects of the organization's operations and security, they do not directly reflect the organization's ability to manage and mitigate vulnerabilities in a timely manner. Thus, time to resolve vulnerabilities stands out as a critical metric for assessing the effectiveness of security measures.
