ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

Mean Time to Remediate (sometimes called Average Remediation Time) measures the elapsed time between the discovery of a vulnerability and its successful fix in production or in the code repository. A shorter MTTR demonstrates that the team is responding to findings promptly, which is exactly what the manager wants to monitor. Vulnerability density focuses on the quantity of issues per code size, not the speed of resolution. Code-coverage percentages indicate testing breadth but reveal nothing about remediation speed. Counting security champions is a staffing measure, not a performance or timing metric.
