Understanding Microsoft Sentinel Fusion for Advanced Threat Detection

Threat intelligence plays a crucial role in Microsoft Sentinel solutions, enabling the detection of multi-stage attacks, ransomware activities, and emerging threats. Fusion technology combines Graph-powered Machine Learning and probabilistic kill chain analysis to detect anomalies and high-fidelity incidents across cloud services, providing a new level of security for organizations. With extensive data coverage and customizable analytics rules, Fusion empowers security teams to monitor and respond to threats effectively.

1. Agenda Threat Intelligence Overview Fusion Incident Investigation

2. Threat intelligence is used throughout Microsoft Sentinel Solutions Data Connectors Incidents Analytics Investigations Playbooks Notebooks Workbooks

3. Microsoft Sentinel Fusion Advanced Multistage Attack Detection Analyzing activities across multiple cloud services into high-fidelity security cases using Graph-powered Machine Learning Activity Anomalous signals Graph-powered ML + probabilistic kill chain Further ML analysis 2.4 . 1.5 2.3 1.1 + Identity (millions of events) Office 365 activity (millions of events) Security alerts (thousands) Azure / AWS / GCP activities (millions of events) Suspicious candidates (hundreds) High Fidelity Incidents Anomalies (thousands) Host activities (millions of events) Firewall (multi-billion events)

4. Fusion Detects 122 multi-stage attack scenarios covering kill chain stages from initial access to impact. Potential ransomware activities at defense evasion and execution stages A new set of ML algorithms that detects emerging threats Extended source signal coverage for all the assets monitored by the SOC team in a Sentinel workspace A new configuration UI to fine tune the input and output of Fusion
