SELinux has been around for a long time, but people are still confused by it.  This talk will explain what the technology is doing, in simple terms using the SELinux coloring book. 

I will then go on to explain the 4 things SELinux is trying to tell you and how you can modify your machine so the SELinux can be run in enforcing mode and your applications will be able to run more securely.

Order matters when bash executes a command, but isn't strictly left to right. Redirects, functions, sub-shells, {brace,tilde,parameter,variable,arithmetic} expansion, pipes, globbing, regular expressions, command substitution and more.

What happens when and how does it affect other portions of the command? Which portions of the command line are evaluated by the shell and which aren't?

Topic: Embedded

The barrage of recent publicity about automotive hacks has left the impression that the automotive cybersecurity problem is hopeless.   Will security problems block autonomous driving from becoming a reality?   Is security-through-obscurity inevitable?   Linux offers a number of applicable features, but the real hope for a robust, affordable solution lies in a thoughtful architectural and network design.  Linux can play a key role in secure automotive systems via its support for diverse hardware, virtualization and a large variety of network protocols.
