A sandbox is an isolated environment used to open files or run software without the risk of affecting the host system or device.
Sandboxing is applied in various areas of information technology, such as cybersecurity and virtualization.
In cybersecurity, sandboxes are used to locate malware in files and software. Web browsers use sandboxes to protect browsers and users from vulnerability exploits.
Virtualization is done using virtual machines – sandboxes that allow users to test operating systems and use files and software within those operating systems without endangering the main system.
