On Chris Shiflett's weblog today there is a new posting today expanding on one of the most dangerous website security issues today - XSS scripting.
I stumbled upon an interesting resource today - the XSS Cheatsheet. This is a really wonderful collection of XSS (cross-site scripting) test cases. If you don't know what XSS is, you might find the following resources helpful: Christian has developed a script for filtering data specifically for XSS. He also has an example implementation where you can try it out for yourself - maybe someone with some free time can try entering all of the test cases to see if any of them expose a weakness.
With XSS, there are just too openings that your site could be vulnerable to - even without you knowing. I'm glad that people are making the public more aware of the issue and giving good ways to help counteract this dangerous threat.
