MarketNetf protecting access to information systems through financial market controls

摘要

This paper describes novel market-based technologies that uniquely establish quantifiable and adjustable limits on the power of attackers, enable verifiable accountability for malicious attacks, and admit systematic and uniform monitoring and detection of attacks. These technologies, incorporated in the MarketNet system, establish a financial economy to regulate the trade and use of access rights in information systems. Resources are instrumented to use currency for access control and monitoring, establishing accountability in their use. Domains control access to their resources through resource prices and budgets available to clients. Domains control and fine tune their exposure to attacks; adjust this exposure in response to emerging risks; detect intrusion attacks through automated, uniform statistical analysis of currency flows; and tune their exposure to resource unavailability by purchasing protection through financial-like instruments.
