There is widespread concern that large-scale malicious attacks on computer networks could cause serious disruption to network services. We present the design of GrIDS Graph-Based Intrusion Detection System. GrIDS collects data about activity on computers and network traac between them. It aggregates this information into activity graphs which reveal the(More)
The IDS community is developing better techniques for collecting and analyzing data in order to handle intrusions in large, distributed environments. To take advantage of this ongoing work, IDSs should be able to dynamically adapt to new and improved components and to changes in the environment. The Intrusion Detection Inter-component Adaptive Negotiation(More)
The problem of removing sensitive information from data before it is released publicly, or turned over to less trusted analysts, underlies much of the unwillingness to share data. The solution is to sanitize, or deidentify, parts of the data. When dealing with network addresses, the set of available addresses is finite. This limits some aspects of the(More)
This report documents the design of the Graph-based Intrusion Detection System GrIDS in reasonable detail. It is intended as a guide to people who wish to understand the implementation, or who have more detailed questions about the design than are addressed elsewhere. GrIDS is a prototype intrusion detection system that was designed to explore the issues(More)
This work explores issues of computational disclosure control. We examine assumptions in the foundations of traditional problem statements and abstract models. We offer a comprehensive framework, based on the notion of an inference game, that unifies various inference problems by parameterizing their problem spaces. This work raises questions regarding the(More)
Necrotizing fasciitis is a rare but specific clinical entity which, if not diagnosed early and treated aggressively, is rapidly fatal. The disease was first described during the Civil War and continues to be associated with a 50% mortality. The infectious process is diagnosed by the presence of a widespread fascial necrosis with extensive undermining of the(More)
The MAGnetic Expansion Control (MAGEC) system is used increasingly in the management of early-onset scoliosis. Good results have been published, but there have been recent reports identifying implant failures that may be associated with significant metallosis surrounding the implants. This article aims to present the current knowledge regarding the(More)
