When Cyber Scoring Systems Diverge: An Empirical Comparison
Kirsi Hellsten, Joni Herttuainen, Ambrose Kam +3
Vulnerability scoring systems underpin cyber patch prioritization and risk management, but their comparative behavior is almost always assessed in the abstract, through correlation…
AI-Based Vulnerability Assessment Capability and Cyber Attack Graph Analysis
Joni Herttuainen, Kirsi Hellsten, Vesa Kuikka +4
Cyber threats targeting mission-critical infrastructure are becoming more sophisticated while the barrier to launching attacks continues to fall. Traditional point solutions like a…
Diffusion-Induced Spatial Attention Overlapping Community Detection
Kosti Koistinen, Vesa Kuikka, Joni Herttuainen +3
Detection of overlapping communities is essential for modelling networks in which nodes participate simultaneously in multiple structural or functional groups. Existing graph neura…
Spatio-Temporal Attention Graph Neural Network: Explaining Causalities With Attention
Kosti Koistinen, Kirsi Hellsten, Joni Herttuainen +1
Industrial Control Systems (ICS) underpin critical infrastructure and face growing cyber-physical threats due to the convergence of operational technology and networked environment…
Integrating Network and Attack Graphs for Service-Centric Impact Analysis
Joni Herttuainen, Vesa Kuikka, Kimmo K. Kaski
Cyberattacks on enterprise networks exploit complex dependencies among infrastructure, services, and applications, which challenge traditional analysis methods that focus on attack…
