What is a security sandbox? Think about the type of sandbox that kids play in. It is small, safe environment where kids can play with just the toys in the sandbox, and they’re temporarily contained so that they can’t touch anything outside the sandbox (unless they leave the sandbox). In computer security, there is […] A few months ago, I had a problem with one of my Virtual Machines (VMs), so I fired up Wireshark, and started capturing traffic. At first I thought I was seeing things. There was a bunch of traffic that was not originating on the VM; it was originating on the host OS. That seemed mighty […] Software is a fact of modern life, but not all of it is safe to use. The real problem is that there is no way for us to tell if a program is good or not.
