MaGOS-IDS: A Mahalanobis-Enhanced OpenMax Method for Graph Neural Network-Based Intrusion Detection

Graph Neural Networks achieve strong closed-set accuracy in network intrusion detection but cannot flag zero-day attacks, because the closed-world assumption forces every input into a known class. OpenMax adds an Extreme Value Theory reject option, yet its Euclidean distance ignores the class-conditional covariance tha...
