Sandbox is a security mechanism used to separate running programs. The Chinese name is sandbox. It is usually used to mitigate the spread of system failures or software vulnerabilities. It is often used to execute untested or untrusted programs or code, possibly from unverified or untrusted third parties, vendors, users or websites, without causing harm to the host or operating system.

Extended information:

Sandbox usually provides guest programs with a strictly controlled set of resources, such as temporary space on disk and memory. Network access, the ability to inspect the host system or read from input devices is often not allowed or severely restricted.

The Sandbox can be considered a specific example of virtualization in the sense of providing a highly controlled environment. Sandboxes are often used to test unverified programs that may contain viruses or other malicious code, without allowing the software to harm the host device.
