As I was looking to see if NSA had updated their guides for RHEL 6 and it turns out they haven’t. I decided it would be a good idea to post about them to give them some better coverage.
This is just a small tip of free and useful information in regards to securing your RHEL/CentOS installation. A lot of the information is general in nature and can therefore be applied to any Linux distribution. It’s definitely worth your time.
I take no credit, the credit goes to NSA for creating the documents to begin with.
