Contributed Session 2: Design of In-Flight Cyber Experimentation for Spacecraft
Meghan Galiardi Sahakian is a Principal Member of the Technical Staff at Sandia National Laboratories. She earned her PhD in mathematics at University of Illinois Urbana-Champaign in 2016. She has since been at Sandia National Laboratories and her work focuses on cyber experimentation including topics such as design of experiments, modeling/simulation/virtualization, and quantitative cyber resilience metrics.
Cyber resilience technologies are critical to ensuring the survival of mission critical assets for space systems. Such emerging cyber resilience technologies ultimately need to be proven out through in-flight experimentation. However, there are significant technical challenges for proving that new technologies actually enhance resilience of spacecraft. In particular, in-flight experimentation suffers from a “low data” problem due to many factors including 1) no physical access limits what types of data can be collected, 2) even if data can be collected, size, weight, and power (SWaP) constraints of the spacecraft make it difficult to store large amounts of data, 3) even if data can be stored, bandwidth constraints limit the transfer of data to the ground in a timely manner, and 4) only a limited number of trials can be performed due to spacecraft scheduling and politics. This talk will discuss a framework developed for design and execution of in-flight cyber experimentation as well as statistical techniques appropriate for analyzing the data. More specifically, we will discuss how data from ground-based test beds can be used to augment the results of in-flight experiments. The discussed framework and statistical techniques will be demonstrated on a use case.
