Open Web Application Security Project
The Open Web Application Security Project (OWASP) is a worldwide free and open community focused on improving the security of application software. Our mission is to make application security “visible”, so that people and organizations can make informed decisions about application security risks. Every one is free to participate in OWASP and all of our materials are available under a free and open software license.
Creating a guide like this is a huge undertaking, requiring the expertise of hundreds of people around the world. There are many different ways to test for security flaws and this guide captures the consensus of the leading experts on how to perform this testing quickly, accurately, and efficiently. OWASP gives like minded security folks the ability to work together and form a leading practice approach to a security problem.
