Intrusion Response as a Resource Allocation Problem Michael Bloem, Tansu Alpcan, and Tamer Basar
 

Summary: Intrusion Response as a Resource Allocation Problem
Michael Bloem, Tansu Alpcan, and Tamer Bas¸ar
Abstract-- We study intrusion response in access control
systems as a resource allocation problem, and address it
within a decision and control framework. By modeling the
interaction between malicious attacker(s) and the intrusion
detection system (IDS) as a noncooperative non-zero sum game,
we develop an algorithm for optimal allocation of the system
administrator's time available for responding to attacks, which
is treated as a scarce resource. This algorithm, referred to as
the Automatic or Administrator Response (AOAR) algorithm,
applies neural network and LP optimization tools. Finally, we
implement an IDS prototype in MATLAB based on a game
theoretical framework, and demonstrate its operation under
various scenarios with and without the AOAR algorithm. Our
approach and the theory developed are general and can be
applied to a variety of IDSs and computer networks.
