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.
With the recent Heartbleed vulnerability shaking the internet, and Docker gaining traction in version 0.10, isolation is the priority. Here is how to secure your Linux Containers (LXC) effectively while maintaining performance.
It is 2014, and the container revolution is here. But before you deploy Docker to production, you need to understand the security risks of shared kernels. Here is a battle-hardened guide to locking down LXC and why KVM is mandatory for true isolation.
While the buzz around Docker and lightweight virtualization grows, the security implications of shared kernels remain a massive blind spot. We dive deep into hardening LXC, managing cgroups, and why KVM isolation is the superior choice for Norwegian data sovereignty.
Container virtualization offers speed, but default configurations leave you wide open. We dive into capability dropping, cgroups resource control, and why KVM isolation is the ultimate security layer for Norwegian mission-critical data.
We benchmark the leading container technologies of 2013. Discover why raw LXC performance beats OpenVZ overhead and how to manage isolation without melting your kernel.
It is 2013, and Linux Containers (LXC) are exploding in popularity. But shared kernels mean shared risks. We explore capability dropping, cgroups, and why KVM remains the isolation king for Norwegian enterprise data.
While the industry buzzes about the new 'Docker' project, serious infrastructure relies on LXC. Here is a deep dive into isolating container traffic using Open vSwitch and HAProxy, ensuring your Norwegian workloads stay compliant and fast.
Container virtualization (LXC/OpenVZ) offers speed, but shared kernels invite disaster. Learn how to harden your isolation, drop kernel capabilities, and why KVM might be the safer bet for critical Norwegian workloads.
Container virtualization offers incredible density, but the shared kernel model exposes risks. From cgroups resource limiting to dropping capabilities, here is how we lock down instances at CoolVDS.
It is March 2013. LXC is entering the enterprise and Docker is making waves. But does sharing a kernel compromise your data? We explore cgroups, namespace isolation, and why hardware virtualization (KVM) remains the gold standard for security in Norway.
Forget the cloud buzzwords. In 2013, real performance comes from understanding packet flow, bridges, and interrupts. We dive deep into architecting low-latency networks for Linux Containers and KVM without melting your CPU.
Container virtualization is the future, but networking across hosts is a nightmare. We explore how to build a robust multi-host network using LXC, GRE tunnels, and Open vSwitch on high-performance Linux clusters.
Container virtualization offers raw speed, but shared kernels pose significant security risks. Learn how to lock down LXC and OpenVZ environments using cgroups, capabilities, and network isolation.
Container virtualization is lightweight but risky. Learn how to lock down LXC and OpenVZ environments against root escalation and resource exhaustion using cgroups, iptables, and the new Kernel 3.8 user namespaces.
It is 2013, and everyone wants lightweight virtualization. But running root inside a container often means root on the host. Here is how to secure LXC against kernel exploits and noisy neighbors before you deploy to production.
Stop wrestling with iptables spaghetti. Learn how to architect scalable, low-latency container networks using Open vSwitch on KVM, focusing on pure performance and Norwegian compliance standards.
Container virtualization offers incredible density, but the shared kernel model exposes significant attack surfaces. We dive into manual cgroup limits, iptables isolation, and why KVM is still king for sensitive data under Norwegian privacy laws.
