OWASP Testing Guide v3 Startup

Planning the new OWASP Testing Guide v3
3rd October 2007: Startup v3 The OWASP Testing Guide v2 was a great success, with thousand download and many many Companies that have adopted it as standard for a Web Application Penetration Testing. Now we would like to begin a new project that is based on v2 but improve it and complete it. In the OWASP Testing Guide v2 we have split the set of tests in 8 sub-categories:
 * Information Gathering
 * Business Logic Testing
 * Authentication Testing
 * Session Management Testing
 * Data Validation Testing
 * Denial of Service Testing
 * Web Services Testing
 * AJAX Testing

The following are my thoughts about the new OWASP Testing Guide v3:

1) Authorization testing missing. As Jeff and Dave said many time before it's important to create a new category. 2)	Information gathering is not a set of vulnerabilities --> not in report --> new category: Passive mode 3)	Business logic testing --> not in report --> Passive mode 4)	Infrastructural test --> new category 5)	Web Services section needs improvement 6)	AJAX Testing section needs improvement 7)	New category: Client side Testing. AJAX and Flash Testing
 * This should include things which were in v1 but dropped from v2, like: OWASP-AC-003 :	Authorization Parameter Manipulation, OWASP-AC-004 : Authorized pages/functions

This analyzes the OWASP Testing Guide v2 vulnerabilities and a plan for create the new v3.

The following clarifications/considerations also need to be made in preparation for v3: 1) Are "OWASP-AUTHN-001 : Authentication endpoint request should be HTTPS" and "OWASP-AUTHN-003 : Credentials transport over an encrypted channel" as they were in v1 fully covered by "OWASP-IG-005 : SSL/TLS Testing"? 2) Are "OWASP-AUTHN-009 : Password Structure" and "OWASP-AUTHN-010 : Blank Passwords" as they were in v1 fully covered by OWASP-AT-003 & OWASP-AT-001? 3) Are all 5 AUTHSM references as they were in v1 fully covered by "OWASP-SM-001 : Session Management Schema"? 4) What does "OWASP-DP-001 : Sensitive Data in HTML" fall under in v2/v3? 5) Are all the SSL Data protection references (DP-003 through DP-007) from v1 fall under "OWASP-IG-005 : SSL/TLS Testing"? 6) Is "OWASP-DS-001 : Locking Customer Accounts" a subset of AUTHN-008 in v1 or AT-006 in v2 or is it really an item on it's own? 7) Are "OWASP-EH-002 : User Error Messages" and "OWASP-EH-001 : Application Error Messages" as they were in v1 meant to fall under "OWASP-IG-004 : Analysis of Error Codes"? If so where would things like overly specific authentication errors appear in the report? (If I understand correctly Information gathering isn't going to be reported) [This would be things like errors messages which actually specify "invalid username" or "invalid password" instead of "Error: the credentials provided are invalid" or similar generic messaging.]
