Measuring the Health of the Global Information Grid

摘要

Monitoring the health of the GIG is one of the most critical aspects of operationalizing cyber missions. This report focuses on the health of the Global Information Grid (GIG), a globally interconnected Department of Defense (DoD) network (of systems) that collects, processes, and manages information for warfighters, policymakers, and support personnel. The three primary components of GIG health (as defined by the customer) include sustainability, reliability and survivability. Sustainability is the consistent performance of network tasks over time; whereas reliability is the accuracy, accessibility and obtainability of information for the user; and survivability being the availability of alternate data route despite internal/external issues. The focus of the project was to design a framework for metrics to assess the health of the GIG. Private sector metrics were extrapolated to measure the sustainability, reliability, and survivability of the GIG and were included as commercial best practices. Also investigated were internal and external threats, such as interference, intrusion, and malicious activity (e.g., cyber- terrorists) that could undermine the system's capability.
