Oracle information rights managment has just released a white paper which I believe defines the future of data leakage prevention and information rights management, also called enterprise rights management.

This paper is an excellent paper and a must read for senior executives, strategists, CIOs and information management and security managers. The introduction to the white paper is summarized below, while this white paper can be accessed by clicking here.

Introduction to the white paper
Organizations face the ongoing challenge of protecting their most sensitive information from being leaked. Two of the most popular solutions used to address this problem are Data Leakage Prevention and Enterprise Rights Management.

This datasheet explains how these technologies are highly complementary
and advises how they can most effectively be used together to provide a complete data leakage solution.

It also describes the integrations today between Oracle Information Rights Management and the DLP products from Symantec, McAfee, InfoWatch and Sophos.
