Patch Management involves patching which components?

Patch Management involves patching which components?

• A. The host and guest operating systems, the software applications, and the virtualization software itself
• B. Only the operating system
• C. End-user workstations only
• D. The network infrastructure only

Answer: (A)

Patch management must cover every layer that the system relies on in a virtualized environment: the host operating system that runs the virtualization software, the guest operating systems inside each virtual machine, the applications installed within those guests, and the virtualization software itself. Each of these components can have its own set of vulnerabilities, so leaving any one of them unpatched leaves an exploitable weakness that could be used to breach or move laterally within the environment. By patching all four areas, you close more potential attack paths and keep the entire stack more secure and stable. It’s not enough to patch only the OS or only end-user devices—the virtualization layer and the applications matter just as much.
