IronBee versus ModSecurity
After spending a couple of weeks talking about IronBee to anyone willing to listen, I have assembled a list of commonly asked questions. Not unexpectedly, the question that tops the list is about the difference between ModSecurity and IronBee.
With IronBee we had a luxury of starting a brand new project with a wealth of experience and a clear idea of what we want to achieve long-term. (This is completely the opposite from where I was when I started ModSecurity.) Thus, we were able to look at our goals and choose the best path to reach them. Because so much of our lives were spent with ModSecurity, the first thing we did was look at its successes and limitations, with the idea that we should keep what's good and improve what's not as good. Two not so good things of ModSecurity stuck out: the lack of a community of developers and the fact that ModSecurity runs only in the Apache web server.
To deal with that, we do two core things differently:
- Community focus. We are making IronBee as open as it can be, not only by using a non-viral open source licence (Apache Software License v2), but also by adopting a transparent community-oriented approach to project management and development. We have also designed IronBee to be highly modular, so that adding to it does not have to mean having to understand the entire architecture and operation. Time will tell, but the idea is that giving up tight control will make for a better open source project in the long run.
- Abstracted data acquisition and host-container interaction model. IronBee is built as a framework from ground up, with focus on portability among web servers and a variety of deployment models (embedded, proxy, passive, batch, etc). Hence the universal application security sensor wording. We want you to have access to IronBee no matter what your platform is.
These two things are actually tightly related. For example, we can't succeed with the second goal without first succeeding with the first one. There are so many platforms (potential host containers) out there, so it is not possible for a small team to support all of them. However, by being open and by structuring the code base to make it easy to add new platforms, we create the right conditions for others to port IronBee to other platforms as the need arises.
