A. B. C. D.A.
To reduce the risk from an unknown vulnerability in a third-party software application, an administrator should use Sandboxing.
A sandbox is a secure, isolated environment that separates running programs from the rest of the system. It allows the administrator to run potentially malicious or untested code in a controlled environment to observe its behavior without putting the system at risk. Sandboxing can help protect against unknown vulnerabilities because any exploits or malicious activity are contained within the sandbox.
Encryption is not an appropriate solution for reducing the risk of an unknown vulnerability. Encryption is a method of transforming data to protect it from unauthorized access. It does not protect against unknown vulnerabilities in software.
Code signing is a security technique that verifies the integrity and authenticity of software. It does not reduce the risk from an unknown vulnerability.
Fuzzing is a technique used to find vulnerabilities in software by sending random inputs to the program. It can be used to identify known vulnerabilities but is not effective at reducing the risk from unknown vulnerabilities.
In summary, sandboxing is the most appropriate solution for reducing the risk from an unknown vulnerability in a third-party software application.
