arXiv:2510.26307v3 Announce Type: replace-cross Abstract: Anomaly detection is a critical task in cybersecurity, where identifying insider threats, access violations, and coordinated attacks is essential for ensuring system resilience. Graph-based approaches have become increasingly important for modeling entity interactions, yet most rely on homogeneous and static structures, which limits their ability to capture the heterogeneity and temporal evolution of real-world environments. Heterogeneous Graph Neural Networks (HGNNs) have emerged as a promising paradigm for anomaly detection by incorpo
The increasing complexity and sophistication of cyber threats necessitate advanced detection methods, pushing the development of more robust AI and graph-based anomaly detection systems.
This development enhances the ability to secure critical digital infrastructure, preventing significant economic and strategic disruption from cyberattacks.
Cybersecurity anomaly detection can now leverage a more nuanced understanding of complex, heterogeneous, and dynamic system interactions, moving beyond static and homogeneous models.
