Web Application Security Testing Cheat Sheet

From OWASP
Jump to: navigation, search

Introduction

This cheat sheet provides a checklist of tasks to be performed during blackbox security testing of a web application.

Purpose

This checklist is intended to be used as an aide memoire for experienced pentesters and should be used in conjunction with the OWASP Testing Guide. It will be updated as the Testing Guide v4 is progressed.

The intention is that this guide will be available as an XML document, with scripts that convert it into formats such as pdf, Media Wiki markup, HTML etc.

This will allow it to be consumed within security tools as well as being available in a format suitable for printing.

All feedback or offers of help will be appreciated - and if you have specific changes you think should be made, please log in and make suggestions.
