R3S: Attack-Mitigation Reasoning in Security Knowledge Graphs

Published
Record updated

Summary

The paper proposes R3S, a framework for attack-mitigation reasoning in security knowledge graphs, addressing gaps in how existing threat intelligence work models causal links between vulnerabilities and mitigation measures. R3S combines H-AIMG, a hierarchical adversary-informed mitigation graph built from APT ecosystem intelligence, with DPSR, which adaptively fuses semantic and structural candidate rankings using an elbow-point detection on score distributions. Experiments on H-AIMG are reported to validate DPSR's effectiveness.
