What Developers Need to Know About Cross Site Request Forgeries

Cross Site Forgery, or cross site request forgery (CSRF), is a web based attack where a malicious web site, instant message, email, or program causes the victim’s Web browser to perform an unwanted action on a trusted site for which the user is currently authenticated.For example, let’s say I am logged into my bank account, or cookie information is stored from a recent login, and I click on a malicious link.
