The author of the presentation lost my respect when I read he is advocating for using SELinux and Linux containers instead of zones and SmartOS, which tells me he is not up to date on security. The whole thing was even made worse by him advocating for the use of continous integration: no, .tar files and Docker images are not the same thing as operating system packages, nor do they come anywhere near the functionality, therefore &quot;DevOps&quot; is insane, especially when the whole thing can be pulled off correctly and securely with SmartOS zones, OS packaging for both delivery and configuration management, and change management process modeling. Those are your airbags, crumple zones, and safety systems, not SELinux, &quot;DevOps&quot;, nor Linux &quot;containers&quot;. The only thing of technical value in the presentation is how to put SSH keys on SmartCards, and even that is just explained as a series of manual steps (hacking in system engineering context), rather than as a turnkey, OS packaging process (full, high quality, repeatable integration). Damn it how I loathe half-baked stuff from people who should know better but don&#x27;t: if you are going to be presenting on security, you better know what you are talking about, or else it is <i>blind leading the blind</i>.
