Azure Sentinel, Microsoft's new cloud SIEM solution, was recently released on the market. Notwithstanding its strengths Sentinel offers limited threat hunting capabilities out of the box and setting up an effective hunting solution is not straightforward. The Sentinel ATT&CK GitHub project is designed to provide guidance on setting up an ATT&CK-driven process monitoring solution within Sentinel; giving DFIR professionals a tool to effectively hunt in the Azure cloud.
The project, building on previous work from the open source DFIR community, provides instructions on how to properly configure Sysmon to monitor and detect specific processes in alignment with MITRE's ATT&CK framework. Secondly it provides clarity on how to onboard Sysmon logs from Windows virtual machines, shedding light on some poorly documented areas, while also offering an open source parser to correctly ingest Sysmon data in conformity with the Open Source Security Event Metadata information model. Thirdly it offers around 120 open source Kusto Query Language alerts ready for deployment; each mapped to a unique MITRE ATT&CK technique. Fourthly it provides a dedicated threat hunting dashboard to help DFIR professionals monitor their environment and execute precise hunts. Finally, Sentinel ATT&CK provides ready-made hunting queries to be leveraged when responding to alert notifications raised by the threat hunting dashboard.
This talk delivers an overview of how the Sentinel ATT&CK project can help organisations establish an effective threat hunting capability in Azure as well as an opportunity to share with the community the strengths and shortcomings of Sentinel when it comes to hunting adversaries within the Microsoft cloud.
