We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy. This article provides a good introductory overview of Linux iptables commands for configuring host-based firewall rules on your Linux systems. Cloud Computing/Cloud Management.

At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. Russell Pope at Kovarus recently wrote about using security groups to manage the VMware NSX distributed firewall. I knew Microsoft was cozying up to Linux, but I honestly didn’t expect they would port SQL Server to Linux.

Flatpak is a (relatively) new application packaging/sandboxing mechanism for Linux applications. The post is a bit geeky but quite informative, and worth reading if SSH bastion hosts are a key part of your architecture.
