O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.
I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
6.28. Blocking Worms with mod_security
Problem

Solution
If you have mod_security installed (see Recipe 2.9), then you can use its basic “core rules” accessory package to intercept many of the most common attack and probe forms that hit Web servers. The core rules package is periodically updated to keep pace with new issues that appear on the Web.
Discussion
Installing the core rules package and following the instructions in the README file makes this very simple. In addition, the files in the package make it easy to write your own rules by illustrating the formats.
