Blackboard-Based Electronic Warfare System, Jeremy Straub

With internet-connected, SCADA and cyber-physical systems becoming the next battlefield for crime and warfare, technologies for defending and attacking these systems are growing in prevalence. For entities with significant asset collections that are prospectively vulnerable to this type of an attack, autonomous response, retaliation and attack capabilities are necessary to respond to a growing threat from numerous sectors. This paper presents a command and control technique for cyberwarfare based on the Blackboard Architecture. It discusses the utility of this approach and proposes a distributed command system that can run across multiple nodes of various types.

Anomaly detection is a widely used technique to detect system intrusions. Anomaly detection in Intrusion Detection and Prevent Systems (IDPS) works by establishing a baseline of normal behavior and classifying points that are at a farther distance away as outliers. The result is an “anomaly score”, or how much a point is an outlier. Recent work has been performed which has examined use of anomaly detection in data streams [1]. We propose a new incremental anomaly detection algorithm which is up to 57,000x faster than the non-incremental version while slightly sacrificing the accuracy of results. We conclude that our method …

Supervisory control and data acquisition (SCADA) systems are becoming more and more com-monplace in many industries today. Industries are making better use of software and large scale control systems to run efficiently, without the need for large amounts of oversight. Security is a particularly large issue with such systems, however. A human must still be involved to ensure smooth operation in the event of catastrophic system error, or unusual circumstanc-es. Human involvement presents problems: operators could make mistakes, configure the system to operate sub-optimally or take malicious actions. This imple-mentation of SCADA security aims to combat these problems.

Wireless power transfer (WPT) can be used to deliver space-generated power to ground stations through the use of microwave beams. WPT satellite power delivery systems have two major failure states: misdi-recting a beam and failing to send power to a station. This project has implemented an expert system to perform pattern recognition in an effort to prevent failures by analyzing the system state and predicting potential failures before they happen in support of space-based testing [1] and deployment [2].
