Method for intrusion detection in a database system
DCFirst Claim
1. A method for detecting intrusion in a database managed by an access control system, comprising:
- defining at least one intrusion detection profile, each profile including a set of item access rates, one of which includes a definition of a number of rows that may be accessed in a predetermined period of time;
associating each user with one of said defined profiles;
receiving a database query from a user;
determining that execution of said query causes said user to exceed an item access rate defined in the profile associated with said user; and
notifying the access control system to alter user authorization, thereby preventing the result of the query from being transmitted to the user.

Abstract
A method for detecting intrusion in a database, managed by an access control system, includes defining at least one intrusion detection profile and associating each user with one of said profiles. Each profile includes at least one item access rate. Further, the method determines whether a result of a query exceeds any one of the item access rates defined in the profile associated with the user. In such a case, the access control system is notified to alter the user authorization, thereby making the received request an unauthorized request, before the result is transmitted to the user. Such a method allows for a real time prevention of intrusion by letting the intrusion detection process interact directly with the access control system, and change the user authority dynamically as a result of the detected intrusion.
