Sandbox Testing for Untrusted Applications

C.

The BEST reason to run an untested application in a sandbox is to prevent the application from acquiring escalated privileges and accessing its host system, which is option C. Running an untested application in a sandbox means that it is isolated from the rest of the system and cannot interact with it directly. This can be useful for testing new or untrusted software without risking damage to the host system or data.

A sandbox is an environment in which an application is executed and isolated from other software running on the same system. Sandboxes are often used to test new or untrusted software, such as software downloaded from the internet, or to run software that is known to be potentially malicious, such as malware or viruses.

Option A, which suggests that running an application in a sandbox would allow it to take full advantage of the host system's resources and storage, is not a valid reason to run an untested application in a sandbox. The purpose of a sandbox is to limit an application's access to system resources and isolate it from other software, so it is not ideal for running an application that requires full access to the system.

Option B, which suggests that running an application in a sandbox would allow it to utilize the host system's antivirus and firewall applications, is not the BEST reason to run an untested application in a sandbox. While it is true that running an application in a sandbox can provide an additional layer of security by allowing the host system's antivirus and firewall applications to monitor it, preventing the application from accessing system resources is the primary goal.

Option D, which suggests that running an application in a sandbox would increase application processing speed, is also not a valid reason to run an untested application in a sandbox. Sandboxes are designed to limit an application's access to system resources, which can result in decreased processing speed. However, the security benefits of running an application in a sandbox outweigh any potential decrease in processing speed.

In summary, the BEST reason to run an untested application in a sandbox is to prevent the application from acquiring escalated privileges and accessing its host system, which is option C.
