Blogs were very popular for a long time, until social media came along. Many blogs are no longer around or are decaying in corners of the internet. Fortunately, there are still enough skilled Linux and security specialists that love to share their knowledge. We looked which blogs are still writing about Linux security and grouped them in this overview. Although there are not many, their insights and non-hyped knowledge is a treasure to be collected.

Tip: most of the authors of these blogs are also available via Twitter.
