Hey @YathindraNikshipth @sowjanyagunupuru, sorry for the late reply and thanks for the ping.

As far as I know, there's no real way to limit or restrict the terminal access of users. Aside from the fact that Theia only acts as a keystroke broker between the browser and the underlying terminal (which makes it technically much more difficult to implement any kind of restrictions) - as long as there's terminal access there are very likely workarounds for any restrictions you put in there (i.e. by renaming executables, using .sh scripts instead of executing the command directly, etc.)

The best way to prevent anything the user does in a terminal from breaking something in the environment, is to completely isolate the Theia environment from the underlying operating system via something like Docker, Kubernetes, a VM or something similar. That's how systems like theia-cloud (Kubernetes), Gitpod or GitHub Codespaces (both use VMs) operate.
