Summary
Blimey O'Reilly! Quite a head spin. At least it was downhill from grsecurity.
The reality, though, is that the work isn't just in installing these things, nor even in understanding them. The real work is in honing the configurations and rulesets, so do. That's the key.
As we leave the main body of this book, I want to leave you with one final thought—other than of me happily propping up the nearest bar having finished this damn thing—and that is this: there is a direct correlation between your expanding knowledge and the retention of security to your local machines, your networks, your server and, therefore, to your WordPress-powered sites.
You read the book. Don't get complacent. Read it again!
