Our Domain Expired and it Took Out All Our Services
Luckily for me, the domain had just expired and we were still within our grace period, so we hadn’t lost the domain. Can you imagine what would have happened if someone else had nabbed it!
I re-registered the domain as quickly as I possibly could, and 15 minutes or so later, our services started coming back up. Fantastic! Crisis averted.

Firefox & AppArmor hardening - Custom rules
Arguably, browsers are the weakest link in one's overall security stack, other than the user, that is. In other words, should something naughty happen to your computer, it's most likely going to involve your browser. To that end, browser vendors as well as operating system companies pay a lot of attention to making this delicate piece of software robust, secure, and isolated from the rest of the system.
A few days ago, I had some spare time, and I sat wondering if there was a way to make browsers in Linux extra secure, especially if one uses custom installations or setups? This led me to tinker with AppArmor, a security framework available in a bunch of Linux distributions. In this article, I want to show you what you can do to make your browser (Firefox) extra hardened. Let's go.
[...]
This brings me to the end of this tutorial, but not the end of this journey. There are many more things to cover, and cover them we shall in future articles. For now, this little guide should give you some basic grasp of how AppArmor works and how you can manually utilize it outside the predefined set of programs shipped by your distro (if any).
I focused on Firefox, because it's my favorite browser, and as an Internet-facing tool, it takes priority over something like your calculator. But the same logic applies to other browsers or programs of similar nature. Well, that would be all for now. Stay tuned for updates [sic]. Why [sic]? You will see in the sequel.
