Which of the following is an example of a coordination center?

Cisco PSIRT (Product Security Incident Response Team) is a vendor-specific team that handles vulnerabilities in Cisco products, not a neutral coordination center.

Microsoft MSRC (Microsoft Security Response Center) is also a vendor PSIRT focused on Microsoft products, not a coordination center serving the broader community.

The CERT Coordination Center (CERT/CC), operated by the Software Engineering Institute at Carnegie Mellon University, was established in 1988 and is the definitive example of a coordination center - it coordinates responses to internet security incidents, conducts research, and shares vulnerability information across organizations and national boundaries without being tied to a single vendor or company.

FIRST (Forum of Incident Response and Security Teams) is a global membership organization and forum that facilitates communication among CSIRTs, but it functions as an industry association rather than a coordination center.
