Graphs for decision support and situational awareness

Curbing fraud is another central graph-based government use case, especially Covid-related fraud. Cyber criminals are exploiting the spread of the pandemic in order to carry out fraud and cyber crime, pinpointing aid programs as easy targets.

In their efforts to hinder such cyber-attacks, researchers at MITRE Corporation, a US federally funded, not-for-profit company, have been using graph technology to develop a special security decision support tool called CyGraph, a cyber warfare analytics, visualization and knowledge management platform.

CyGraph brings together isolated data and events into an ongoing overall picture for decision support and situational awareness. It prioritizes exposed vulnerabilities mapped to specified, identified potential threats, in the context of protecting mission-critical assets. It also correlates intrusion alerts to known vulnerability paths and suggests the best course of action for responding to attacks.

For Steven Noel, a cyber security researcher at MITRE, “graph queries make it possible to focus our analysis on the relevant portions of attack graphs, allowing us to pinpoint vulnerabilities and target responses”. The use of graph database technology provides insight into the mission impact of cyber activities. Graph layers (network infrastructure, cyber defense posture, mission dependencies, etc.) define subsets of the overall model space with connections within and across each layer. Analysts also gain visibility into operations for global situational awareness.
