Containerization is revolutionizing deployment, but the security model in 2014 is still the Wild West. From Shellshock mitigation to kernel namespaces, here is how to run Docker securely on Norwegian infrastructure without exposing root.
In the wake of Heartbleed and Shellshock, the old firewall-castle model is obsolete. Learn how to lock down your infrastructure using 'Zero Trust' principles on Linux, specifically tailored for Norwegian data sovereignty.
Docker is exploding in popularity across Norway's dev teams, but default configurations are a security nightmare. We dissect kernel namespaces, capability dropping, and why true hardware virtualization (KVM) remains the only safe harbor for production data.
It is late 2014 and Docker is eating the world. But running containers in production without hardening is negligence. We dissect LXC isolation, kernel exploits, and why KVM is your safety net.

With the Shellshock vulnerability still echoing through data centers, it is time to get serious about container isolation. We explore kernel namespaces, capability dropping, and why a KVM-backed VPS is still your best defense line.
The old model of 'trusted LAN, untrusted WAN' is obsolete. Following the chaos of Heartbleed and Shellshock, we explore how to build a manual Zero-Trust architecture using iptables, strict SSH tunneling, and KVM isolation on Norwegian infrastructure.
Hardware fails. Humans make mistakes. If your disaster recovery plan relies on a single RAID array or a manual FTP transfer, you are already down. Here is the battle-tested blueprint for automated redundancy in Norway's hosting landscape.
Hardware fails. Networks congest. In a post-Snowden world, relying on a single US-based cloud is professional negligence. We detail a battle-tested disaster recovery setup using KVM, MySQL Replication, and Oslo-based redundancy.
With the release of Docker 1.0, everyone wants to containerize. But as a sysadmin managing Norwegian infrastructure, I see gaping security holes. Here is how to lock down LXC and Docker using AppArmor, capabilities, and the right virtualization layer.
