How to: Other Guides
There are many guides provided by experts, industry leaders, and the distributions themselves. It is not practical, and sometimes against copyright, to include everything from those guides. I recommend you check them out before starting with this guide.

- The [Center for Internet Security (CIS)](https://www.cisecurity.org/) provides [benchmarks](https://www.cisecurity.org/cis-benchmarks/) that are exhaustive, industry trusted, step-by-step instructions for securing many flavors of Linux. Check their [About Us](https://www.cisecurity.org/about-us/) page for details. My recommendation is to go through this guide (the one you're reading here) first and THEN CIS's guide. That way their recommendations will trump anything in this guide.
- For distribution specific hardening/security guides, check your distributions documentation.
