Security applications and technologies for IP communications networks.

This white paper briefly highlights past network security issues, examines the shortcomings of existing security architectures that do not address the future’s security requirements, and presents possible approaches that can solve them. Notable among these approaches are those for security applications and technologies that go beyond the basic need to control “access” to the network to those that can actually securely control the network and its content, and are likely to become prevalent in the world’s current evolution toward IP communications networks.
