Improving Satellite Security Through Incremental Anomaly Detection On Large, Static Datasets, Connor Hamlet, Matthew Russell, Jeremy Straub, Scott Kerlin

Jeremy Straub

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 …

Small Satellite Communications Security And Student Learning In The Development Of Ground Station Software, Scott Kerlin, Jeremy Straub, Jacob Huhn, Alexander Lewis

Jeremy Straub

Communications security is gaining importance as small spacecraft include actuator capabilities (i.e., propulsion), payloads which could be misappropriated (i.e., high resolution cameras), and research missions with high value/cost. However, security is limited by capability, interoperability and regulation. Additionally, as the small satellite community becomes more mainstream and diverse, the lack of cheap, limited-to-no configuration, pluggable security modules for small satellites also presents a limit for user adoption of security.

This paper discusses a prospective approach for incorporating robust security into a student-developed ground station created at the University of North Dakota as part of a Computer Science Department senior design …
