Security of an In-orbit Satellite: Detection of Compromise Through Integrity — Stratosphere Laboratory

Small satellites are increasingly vulnerable to cyberattacks, yet their resource constraints make implementing robust security mechanisms a significant challenge. This thesis explores how to protect the integrity of satellite and payload data against malicious software running in orbit, a problem th

Poster: Multi-Objective Model Selection Pipeline for Network Flow Classification at POSTERS 2026 — Stratosphere Laboratory

Training classifiers for network intrusion detection is hindered by two types of problems: data challenges (lack of labels, class imbalance, non-IID data, and concept drift) and engineering challenges (memory & compute efficiency, data ingestion, parallel training, and hyperparameter optimizatio
