I'm about to setup a VPS that will host multiple websites of my companies that only I will have access to. These websites are our own sites and, therefor, it's my own code that will be running on the server.
So I'm wondering, should I bother separating sites with their own user/group to sandbox each site? Obviously, I won't be uploading a shell to one of the sites to read files from another site - I can just SSH in :>
But, I'm thinking in terms of if one of the sites gets hacked by someone else due to a vuln being found in a CMS/my code/etc. If I sandbox it off, then that one site gets hacked rather than all.
Should I bother with this?
