Which of the following solutions should an administrator use to reduce the risk from an unknown vulnerability in a third-party software application?

The correct answer is A. Sandboxing. To mitigate risks from unknown vulnerabilities in third-party applications, an administrator should implement sandboxing, which isolates the application to prevent exploits from affecting the broader system.

Why each option

To mitigate risks from unknown vulnerabilities in third-party applications, an administrator should implement sandboxing, which isolates the application to prevent exploits from affecting the broader system.

ASandboxingCorrect

Sandboxing creates an isolated environment for the third-party application, ensuring that any exploits leveraging an unknown vulnerability are contained within that sandbox and cannot compromise the underlying operating system or other critical resources.

BEncryption

Encryption primarily protects data confidentiality at rest or in transit, and does not prevent an unknown software vulnerability from being exploited.

CCode signing

Code signing verifies the authenticity and integrity of software, but it does not prevent legitimate, signed software from containing or exposing unknown vulnerabilities.

DFuzzing

Fuzzing is a testing technique used to discover vulnerabilities before deployment, not a runtime control to reduce risk from an unknown vulnerability in deployed software.
