As computing technology becomes increasingly pervasive and interconnected, mobility leads to shorter-lasting relationships between end-points with many different security requirements. Also the rapid development of new service landscapes calls for standardized, yet highly flexible security protocols. It has been demonstrated that the increasing number of application contexts of these highly flexible...
Most intrusion detection systems deployed today apply the misuse detection approach. Misuse detection compares recorded audit data with predefined patterns denoted as signatures. A signature is usually empirically engineered based on experience and expert knowledge. This induces relatively long development times for novel signatures causing inappropriate long vulnerability windows. Methods for a systematic...
We present the challenges facing businesses wishing to outsource processes to service providers who must maintain regulatory compliance via data access control procedures. We argue that it is not currently possible to capture the necessary agreements, and supporting evidence, pertaining to the usage of data a client may send to a service provider. As a result, the richness of evidence and controls...
Workflow management systems provide some of the required technical means to preserve integrity, confidentiality and availability at the control-, data- and task assignment layers of a workflow. We currently observe a move away from predefined strict workflow enforcement approaches towards supporting exceptions which are difficult to foresee when modelling a workflow. One specific approach for exception...
This paper provides a general and comprehensive approach to implementing misuse detection on expert systems and an in-depth analysis of the effectiveness of the optimization strategies of the Rete algorithm wrt. the general implementation approach. General efficiency limits of Rete- based expert systems in the domain of misuse detection are determined analytically and validated experimentally. We...
