Network Survivability Analysis of the Navy and Marine Corps Intranet (NMCI)

摘要

NMCI is a mechanism to transform the Navy and Marine Corps information systems and prepare 21st century warfare. Just as the Internet has transformed business and commerce around the globe, NMCI may transform the U.S. Navy and Marine Corps by harnessing the power of an integrated network. The Navy and Marine Corps Intranet constitutes the first major step into a truly network- centric warfare environment and makes them full participants in the cyber world. This network will handle the data on which an increasing percentage of the Navy and Marine Corps mission essential services will rely. Yet, the hardware and software that make up these systems have demonstrated vulnerabilities that put these mission essential functions at risk. Consequently, the Navy and Marine Corps must consider systems and strategies that address the need for survivability of the mission essential functions in the same manner applied to major weapons systems on the battlefield. 'Network survivability' is a field of study that addresses exactly this issue. Developed in 199S under a Department of Defense contract by the Carnegie Mellon University Software Engineering Institute, network survivability addresses the need of a network to fulfill its essential mission in the presence of failures, compromise, or attack. This thesis examines the Navy and Marine Corps Intranet mission and structure in an attempt to determine its inherent survivability and ability to support the needs of the Navy and Marine Corps team. It focuses on identifying the network mission functions and the ability of the network architecture to produce the required survivability characteristics. Based on this examination I propose a mission definition for NMCI and highlight the need within the security architecture to achieve a survivable NMCI network.
