I had a fascinating job once that involved designing hardening procedures for systems we were going to use for security-related projects. This was probably 15 years ago, and not only were guides a little thin on the ground for the Linux distribution I was using, but what we were doing was quite niche. At first, I think I'd assumed I could just write a script to close down a few holes that originated from daemons1 that had been left running for no reasons: httpd, sendmail, stuff like that.

If you are new to this series (and to Linux), take a look at our first installment. In that article, we worked our way through the tree-like structure of the Linux filesystem, or more precisely, the File Hierarchy Standard. I recommend reading through it to make sure you understand what you can and cannot safely touch. Because this time around, I’ll show how to get all touchy-feely with your directories.

At KubeCon + CloudNativeCon in Copenhagen, Denmark recently, I met many users, technologists, and business leaders -- all aware of the dramatic pace of innovation and eager to learn about the new technologies that are coming out of open source space.

We also want to ensure that our personal information (e.g., a site password) is secure, and scholarly publishers have a responsibility to the community to protect our data.

Internet Protocol (IP) needs no introduction—we all use it daily. Even if you don't use it directly, when you type website-name.com on your web browser, it looks up the IP address of that URL and then loads the website.

Today, the U.S. Senate passed a Congressional Review Act (CRA) resolution to save net neutrality and overturn the FCC’s disastrous order to end net neutrality protections. We’re pleased this resolution passed – it’s a huge step, but the battle to protect net neutrality and reinstate the 2015 rules isn’t over. The next step is for the motion to go to the House of Representatives for a vote before the order is supposed to go into effect on June 11. Unfortunately, the rules in the House will make passage much harder than in the Senate
