[Owasp-testing] Updated Index draft

[kevin horvath]

Hello Team,

I know everyone is busy writing but if anyone could help and do a
quick review of one of my sections I would appreciate it.  I know that
is going to be covered starting next month, but I have a few other
sections to write and want to make sure I am on the right track here
before I start the others.  Thanks again and I appreciate any
assistance.
