(This setting is used to disable the connector.)Īccording to Microsoft docs, these are the pre-defined security event collection groups depending on the tier set: None - No security or AppLocker events.It covers only events that might indicate a successful breach, and other important events that have very low rates of occurrence. This set does not contain a full audit trail. Minimal - A small set of events that might indicate potential threats.This is because the main point of the Common set is to reduce the volume of events to a more manageable level, while still maintaining full audit trail capability. Common - A standard set of events for auditing purposes. The Common event set may contain some types of events that aren't so common.All events - All Windows security and AppLocker events.For example, these are the only options to collect data from Windows machines with the old connector: The old connector is not flexible enough to choose what specific events to collect. In order to apply a DCR to a virtual machine, one needs to create an association between the machine and the rule. A virtual machine may have an association with multiple DCRs, and a DCR may have multiple virtual machines associated with it.įor more detailed information about setting up the Windows Security Events connector with both Log Analytics Agent and Azure Monitor Agents manually, take a look at this document. DCRs define what data to collect and where it should be sent. Here is where we can set it to send data to the log analytics workspace backing up our Azure Sentinel instance. The new connector, on the other hand, uses a combination of Data Connection Rules (DCR) and Data Connector Rules Association (DCRA). In your Azure Sentinel data connector's view, you can now see both connectors:Ī New Version? What is New? Data Connector Deploymentīesides using the Log Analytics Agent to collect and ship events, the old connector uses the Data Sources resource from the Log Analytics Workspace resource to set the collection tier of Windows security events. Windows Security Events (new version): Based on the new Azure Monitor Agent (AMA).Security events (legacy version): Based on the Log Analytics Agent (Usually known as the Microsoft Monitoring Agent (MMA) or Operations Management Suite (OMS) agent).Therefore, I am constantly trying to improve the deployment templates as I cover more scenarios. Feedback is greatly appreciated.Ī New Version of the Windows Security Events Connector?Īccording to Microsoft docs , the Windows Security Events connector lets you stream security events from any Windows server (physical or virtual, on-premises or in any cloud) connected to your Azure Sentinel workspace. After last week, there are now two versions of this connector: Connect Windows security event data to Azure Sentinel (tabbed version) | Microsoft DocsĪzure Sentinel2Go is an open-source project maintained and developed by the Open Threat Research community to automate the deployment of an Azure Sentinel research lab and a data ingestion pipeline to consume pre-recorded datasets. Every environment I release through this initiative is an environment I use and test while performing research as part of my role in the MSTIC R&D team.A powerful agent for Azure Monitor and a simpler world of data collection now generally available!.Azure Monitor Agent and Data Collection Rules now generally available | Azure updates | Microsoft Az.I highly recommend reading the following blog posts to learn more about the announcement of the new Azure Monitor features and the Windows Security Events data connector: In this post, I will talk about the new features of the new data connector and how to automate the deployment of an Azure Sentinel instance with the connector enabled, the creation and association of DCRs and installation of the AMA on a Windows workstation. This is an extension of a blog post I wrote, last year (2020), where I covered the collection of Windows security events via the Log Analytics Agent (Legacy). This is the first data connector created leveraging the new generally available Azure Monitor Agent (AMA) and Data Collection Rules (DCR) features from the Azure Monitor ecosystem. As any other new feature in Azure Sentinel, I wanted to expedite the testing process and empower others in the InfoSec community through a lab environment to learn more about it. Last week, on Monday June 14 th , 2021, a new version of the Windows Security Events data connector reached public preview.
