I just uploaded my talk Hashdays 2012 „Self-Defending Databases“ to the Red-Database-Security website. The talk explains how to detect SQL Injection attacks in databases (Oracle/MSSQL/MySQL) and how to react in case of a SQL Injection (e.g. done with Pangolin, Havij or Netsparker).
Initially the idea covered only Oracle and MSSQL but Xavier Mertens extend the concept to MySQL (MySQL Attacks Self-Detection) after he saw my presentation at the Hashdays Management Session.
