Computer Network Denial Of Service Denial

October 1st, 2009 No comments

1. Cross site scripting (XSS)

The problem: The “most prevalent and pernicious” Web application security vulnerability, XSS flaws happen when an application sends user data to a Web browser without first validating or encoding the content.
