Of the following types of SOCs (Security Operations Centers), which one would be MOST likely used if the CISO has decided to outsource the infrastructure and administration of it?

A Virtual SOC (vSOC) is the most likely option when a CISO decides to outsource the infrastructure and administration of a Security Operations Center. vSOCs provide SOC services remotely through managed service providers, eliminating the need for in-house infrastructure while offering flexibility and scalability. Dedicated SOCs (B) are in-house setups, Fusion SOCs (C) focus on cross-functional collaboration, and Command SOCs (D) are typically centralized for large-scale operations.
