Abstract

Unauthorized URL requests are detected based on individual user's access map(s). An access map describes legitimate paths that a user may be led from one URL to another URL. Additional information on individual URLs forming the paths, such as whether a particular URL is a start URL or a critical URL, is also included in the access map. The access map may be updated based on the most currently available information. When a URL request is made from a client device associated with a user, and it if is determined that the requested URL may potentially suffer from CSRF attacks, then the requested URL and its referral URL are compared against the URL paths in the user's access map to determine whether the URL request is unauthorized. If so, then an alert may be raised.
