Wouldso would I actually do exactly the same factor for my server side code want to see my php programmer isn't doing exactly the same factor!??
- Check every checkin/do code reviews.
- If you cannot believe in developers, search for different developers.
Make use of the Firebug extension for Opera, and let the console. It will highlight any ajax Publish or GET demands.
knowing some degree of programming, do CODE REVIEW.
Not an immediate answer, but related... When I clarified here, you can examine the book Ajax Security. I do not recall whether it particularly handles your direct concern of personnel trust, however it does cope with many concrete issues of security in this region and could give you good quality suggestions for items to watch out for, or preventative measures to consider.
