Section 4: Mitigating the WebGoat lessons

Project metrics

See Section 2 for the WebGoat lesson Table of Contents, and an overview of the results from doing the WebGoat lessons. Appendix A contains a zip file which is made up of the lesson plans and solutions - in HTML format - which were taken from WebGoat and can be viewed stand-alone.

Out of 51 possible lessons, the following are teaching lessons, not vulnerabilities, and therefore have no context for ModSecurity rules:

• 1.1 Http Basics
• 4.1 Password Strength
• 15.3 Bypass Client Side JavaScript Validation
• 17.1 Create a SOAP Request

Therefore there is a total number of 47 lessons to do; half is 24 so that was the goal of the first 50% of project completion. The lowest hanging fruit was taken first because considerable effort was put into: (1) setup and configuration of the environment; (2) getting familiar with WebGoat and taking all of the lessons; (3) learning ModSecurity (and Remo); (4) re-learning regular expressions; (5) learning Lua script; and (6) developing an efficient work methodology.

The total number of sublessons mitigated by ModSecurity rules: 25 - thereby achieving the goal of at least 50% of sublessons mitigated.

They are:

• Sublesson 1.2
• Sublesson 2.4
• Sublessons 4.2, 4.4, 4.5
• Sublesson 6.1
• Sublessons 8.1, 8.2, 8.4, 8.5, 8.7
• Sublesson 10.1
• Sublessons 11.1, 11.2, 11.3, 11.4, 11.5, 11.6, 11.7, 11.8
• Sublesson 13.1
• Sublessons 15.1, 15.2
• Sublessons 17.3, 17.4
