Like many others in the technology industry, I share a passion for artificial intelligence (AI). This year at OpenStack Summit in Berlin, I presented a talk around parallel AI training. OpenStack lends itself well to big data problems.

Security technical implementation guides (STIGs) provide a standardized set of security protocols for practically any system. From networks to servers and computers, STIGs are designed to enhance overall security and reduce vulnerabilities. But what happens when the guidelines vary across an enterprise? How do you apply these to a specific product without breaking it? Challenge accepted.

Most of us have been using PAM when authenticating without really thinking about it, but for the few of us that have actually tried to make sense of it, PAM is the partner that always says “no”, unless otherwise stated. It’s the bane of any sysadmin’s existence when it comes to making system x secure, and it becomes a major pain point on and off when I forget about the normal rules of engagement.

Hello, my name is Christopher Tate and I want to show you how to set up virtualization and a virtual machine for DNS and Identity Management to open our OpenShift web console and routes to the network.
In my previous videos, I showed you how to install OpenShift with valid SSL certificates.
Hey Tate: Step by step securing OpenShift and routes with SSL certificates for development.

I created this series of videos to show how to first, purchase a domain name for cheap, to use for valid SSL certificates and URLs for all your applications. I do this for learning and developing applications, not just for deploying to production. Then I show how to generate a free SSL certificate for secure, verified https connections to your sites. Then I show you how to run OpenShift locally, from the ground up, with SSL certificates for the web console, and all routes.

Next week in Vancouver, Canada thousands of OpenStack users will meet at the seventeenth annual OpenStack Summit. This year will expand beyond OpenStack to cover topics like CI/CD, container infrastructure, Edge Computing, HPC, Open Source communities, private, hybrid, and public cloud, and telecommunications.

Remote Execution is a very useful feature of Satellite 6. This long anticipated feature made its first appearance in version 6.2. Much has changed since the days of Remote Command in Satellite 5. Most significantly Remote Execution relies on ssh, instead of a client side daemon. This change introduces some new security considerations for hardened environments. Let’s take a closer look.
