As the lead cybersecurity analyst for XYZ Corp, you are developing a report for management on the current security posture of the organization. In the context of vulnerability management, which metric would be most appropriate to include in your report to demonstrate the organization’s improvement in identifying and mitigating vulnerabilities over time?
Mean time to remediate (MTTR) is a key performance indicator that measures the average time taken to fix a vulnerability after it has been detected. This metric is valuable to management as it shows the responsiveness and efficiency of the vulnerability management process. A decreasing MTTR over time indicates an improvement in the process. Mean time between failures (MTBF) is mostly related to hardware reliability and not directly applicable to vulnerability management. Time to first acknowledgement reflects the initial response, not the full remediation process. Percentage of uptime is a metric related to availability, not vulnerability management. Number of patches applied does not provide information on the speed or effectiveness of the remediation process.
