 Hi, I'm going to be demoing SecCop, a new security feature we're aiming to add to Docker containers. SecCop enables us to restrict certain system calls, preventing them from being used within containers. This allows us to add a new line of defense around the kernel to prevent container breakouts. I'm going to start by disabling SE Linux so you can see that it's actually me that is causing these changes. Next, we're going to run a dark container using a fairly standard command line, except we're going to add something new here. You can see here that we are going to have SecCop deny the NanoSleep system call, which is used in a few common commands, including sleep. And you can see here nothing appears to be different within the container. All appears to be well. So let's ask the container to sleep for a second. And you can see here we're getting operation not permitted off of the real-time clock. This is something that should never happen. This is not one of the normal error modes of that command. Now let's do this again without the SecCop command, and you can see it's sleeping, as you would expect. So this is just the most basic application of this. In a typical use-the-scenario, we would define a black list of system calls that would never be allowed to build containers, or alternatively a white list of the system calls that a container requires to run to allow it to use those and no others. Please note that the command line here that we're using is just a demo, and this is not a final version, nor is this actually in Docker at this point. This is still something that's making its way upstream. Thank you.
