Information Sharing for Computing Trust Metrics on COTS Electronic Components

Abstract

The Department of Defense (DoD) has become highly reliant on commercial-off-the-shelf (COTS) technology in mission-critical unclassified systems to reduce both the cost time to acquire a system, and standardize support for deployed systems. It is challenging for the DoD to determine whether and how much to trust in COTS components, given uncertainty and incomplete information about the developers and suppliers of COTS components as well as the capabilities provided by COTS components. The purpose of this thesis is to explore the current landscape of DoD information assurance (IA) as it pertains to COTS components, show how Josang's trust model can be used to calculate trust based on opinions provided by multiple government and non-government services, and explore the need for cross-domain sharing of information to support populating, maintaining, and using the trust models.
