A sandbox environment is designed to isolate and contain software or programs, preventing them from interacting with other parts of the system or network. This isolation can be used to safely run untested or untrusted programs or code without risking the integrity of the host system or network. Setting up a virtual machine within a sandbox environment ensures that the VM has no communication with other devices over the network, providing a controlled and secure environment for testing or development purposes.
