Within an organization’s vulnerability management program, who has the responsibility to implement remediation actions?

In a typical vulnerability management program, the responsibility for implementing remediation actions, such as applying patches or reconfiguring systems, falls to the team or individual who manages the affected asset. The system administrator is responsible for the configuration, maintenance, and operational integrity of servers and operating systems. Therefore, they are the ones who perform the hands-on technical work to fix identified vulnerabilities on the systems they manage, following the guidance and priorities set by the security team.

A. The security officer is responsible for governance and oversight of the program, not hands-on implementation.
B. The data owner is a business role responsible for data classification and accepting risk, not technical remediation.
C. The vulnerability engineer typically identifies and analyzes vulnerabilities, but does not manage the production systems to remediate them.

Section 2.3, "Roles and Responsibilities," page 10. This guide explicitly states that system administrators are key personnel responsible for the deployment and installation of patches on systems.

Chapter 10, "Operations Security," describes the role of a system administrator as including the responsibility to "apply all necessary security patches to systems," which is a core remediation activity.
