I’ve read that standard containers are optimized for developer productivity and not security, which makes sense.
But then what would be ideal to use for security? Suppose I want to isolate environments from each other for security purposes, to run questionable programs or reduce attack surface. What are some secure solutions?
Something without the performance hit of VMs
There are multiple use cases I have in mind, but one of them is running proprietary software I don’t outright trust. For example, zoom video conferencing for work, or steam for games.
Docker isnt build to run these type of Programms. You should look into sandbox environments to test these apps.
Try firejail and flatseal for that.
