Multi-Layer Network Security Architecture

Abstract

This month is the last of four installments on multi-layer network architectures. We talked about the need for satellite, fiber and wireless network architectures to include all layers in its designs. When they are integrated together to form one Internet, issues on internetworking appear at all layers including the Application Layer. All the more critical are network architectures with coherent multi-layer designs. This last piece addresses network security and resiliency and the need for a multi-layer approach to an effective design.
