Open source vulnerability scanner for Linux systems - Lynis
2014-04-15 (last updated at October 20th, 2014) Michael BoelenAuditing, Linux, Lynis, Software There are several open source vulnerability scanners for Linux, like OpenVAS. While tools like these are powerful as well, we will have a look at Lynis, our auditing tool to detect vulnerabilities of Linux and Unix systems. Why is it different than others and how can it help you in securing your systems?

Linux kernel security and how to improve it
2014-04-27 (last updated at June 26th, 2018) Michael BoelenHardening, Kernel, Linux Every system is as strong as its weakest link. In the case of an operating system like Linux, one weakness in the kernel could result in a security breach. This article covers the Linux kernel features and how they work. Kernel features Live kernel patching As the kernel is similar to other software, it receives updates to improve it.
Docker Security: Best Practices for your Vessel & Containers
Everything you need to know about Docker security. Introduction into Docker Docker became very popular in a matter of just a few years. Operating systems like CoreOS use Docker to power the system by running applications on top of their own lightweight platform. Docker in its turn, provides utilities around technologies like Linux container technology (e.g. LXC, systemd-nspawn, libvirt). Previously Docker could be described as the “automated LXC”, now it’s actually even more powerful.
The state of Linux security
In the last 10 years, GNU/Linux achieved something some foresaw as almost impossible: powering both the smallest and biggest devices in the world, and everything in between. Only the desktop is not a conquered terrain yet. The year 2016 had an impact on the world, from both a real life and digital perspective. Some people found their personal details leaked on the internet; others found their software being backdoored. Let’s have a look back on what happened last year regarding Linux security.
Livepatch: Linux kernel updates without rebooting - Linux Audit
If you run a Linux server, software patching is a task that will have to be performed on a weekly (or daily) basis. Although most programs can be auto-restarted with a tool like needrestart, there is one exception: the kernel. Wouldn’t it be a nice if we could patch the kernel, without the mandatory reboot? Here is livepatch, the feature of the Linux kernel that makes it possible.
Using encrypted documents with vim - Linux Audit
Everyone has secrets. Or at least some data you don’t want to show others, right? Vim is a common editor to be found on Linux systems. It has an option to create and use encrypted files. We will look at how to configure it and use this encryption capability. Encryption is the process of fiddling with data so that others no longer can’t read it. The idea is that you still can, so when we speak about encryption, we can’t ignore decryption. This also means that we need a good cryptographic algorithm.
How to Promote your Open Source Project - Linux Audit
Tips and suggestions to get your open source project noticed Nowadays it is easy to start an open source project. People over the world start new projects daily, as can be seen on the popular site GitHub. Unfortunately, many of these projects simply don’t get traction and end up as inactive ideas on the web. Traction in software project is similar to speeding up a car. If you give too much gas, you might end at undesired places, too little and it takes too long to reach your destiny.
How the web changes with HTTP/2: Performance and Security
On invitation by the Dutch consultancy firm Snow, I attended their Snow Unix Event (SUE). It was the third time in a row, with again an impressive lineup of speakers. As I worked previously for the company, I expected no less than that. The theme was about knowledge sharing. That sounds like an invitation to also share some of the biggest insights I learned. Let’s start with the HTTP/2 insights by Daniel Stenberg. The first talk of the day was by Daniel Stenberg.
Deleting Outdated HPKP Key Pins in Firefox - Linux Audit
HPKP is a great technology to pin a certificate to a website. On first use of a domain, the browser of the client checks if key pinning is available. Upon a next visit, the browser applies an additional check if the certificate(s) provided is available in the previous list of whitelisted sites. Sometimes things go wrong with HPKP and you won’t be able to access a particular page. The best action is first to contact the website and see if they are aware of the problem.
