This section details the strategy and work done in order to reach the 50% milestone of the project. When the term 'mitigated' is used throughout this document, it is used in the sense that the WebGoat vulnerability in a lesson has been prevented from being exploited by using ModSecurity.
Project Setup and Environment
Disclaimer: The background of the project team member is software development and not system/network administration, so any suggestions or comments to improve the following configurations are welcome.
Network/hardware/software
The operating system is Kubuntu 7.10 on a Dell Inspiron laptop. Apache 2.2.7 and Tomcat 5.5 from the Kubuntu distribution is used; mod_jk glues Tomcat to Apache. Mod_proxy is used and configured so that Apache has a static IP address, WebGoat is accessible via port 80, and is available to other PCs on the internal network. For security, the NetGear wireless router is configured to block all HTTP & HTTPS traffic to and from the Web server to the outside world.
Firefox 2.0, Internet Explorer 7.0, and Opera 9.26 were used remotely on Windows XP SP2, and occasionally Firefox 2.0 was used on the Web server itself.
WebGoat version 5.2 Beta 1 was used. The standard release of WebGoat 5.2 was posted to Google Code on 12 July 2008 and the second half of this project will be based on the standard release. Also, the ModSecurity solutions provided for the first 50% will be re-tested.
ModSecurity 2.5.1 was compiled, installed and used. For the 2nd half of the project, the current release of ModSecurity 2.5.5 will be utilized.
Tools used
- WebScarab/Paros Proxy web proxies: The solutions use WebScarab and the project member used both WebScarab and Paros Proxy interchangably throughout the project.
- Remo - Rule Editor for ModSecurity (http://remo.netnea.com/) was invaluable to get started with an easy-to-use GUI that builds ModSecurity rules. Besides the tutorial video on the Remo site, another very helpful tutorial is at http://www.howtoforge.com/remo_modsecurity_apache.
- Regex tools: The Regex Coach 0.9.2 (http://weitz.de/regex-coach/) and Expresso 3.0 (http://www.ultrapico.com/Expresso.htm) were used for building, testing, and analyzing regular expressions.
- Lua tools: The standalone binaries and all related documentation and artifacts for using the Lua scripting language can be found starting at http://www.lua.org. A big help was a version of Notepad2 with Lua support (http://zigmar.googlepages.com/notepad2withluasupport).
- The ModSecurity debug file: It's simply not possible to go without the ModSecurity debug file set at level 9 for debugging.
- A text editor with line numbers: the ModSecurity debug file makes extensive references to line numbers with rulesets, so having a text editor with line numbers is essential for a debugging session. 'kate' was used on Kubuntu 7.10 and 'Notepad2' was used on WinXP.
