Create an Automation Account from the Azure PortalĢ. Attach the Playbook to the relevant Analytics rule in Azure Sentinel.ġ. Deploy the Automation Hybrid Worker solution from the Azure Market place above remains blocked even after subsequent Azure AD connect syncs with Azure cloud.īefore you begin to review the pre-requisites of deploying a Hybrid Runbook Worker here: Deploy a Windows Hybrid Runbook Worker in Azure Automation | Microsoft Docs Those connectors are based on one of the technologies listed below. Built-in connectors are included in the Azure Sentinel documentation and the data connectors pane in the product itself. The playbook includes the " create hybrid automation job" action, which executes a PowerShell script against the on-prem DC to block the user. Refer to the Azure Sentinel connector documentation for more information. The incident has the playbook attached to kick off the actions needed to block user access both on the cloud and on on-prem AD Existing Microsoft Sentinel Analytics rule generates an incident requiring a user to be blocked from further domain access. Automation Accounts can be used to perform cloud-based automation across Azure and non-Azure environments, including on Linux and Windows servers sitting in AWS, and GCP clouds so long as those machines have the Log Analytics agent installed.Ī typical use-case for this solution would flow as below: To address the problem, this solution leverages the Automation Accounts and Hybrid Worker features across on-prem Windows resources & Azure. This presents challenges when you want to orchestrate a user property change from Azure that needs to persist even after the sync happens. However, given that the on-prem side is the authoritative source of truth, any changes, such as disabling a user in the cloud (Azure AD), are overridden by the setting defined in the on-prem AD during the next sync. Get started detecting threats with Microsoft Sentinel.Many organizations have an on-premises Active Directory infrastructure that is synced to Azure AD in the cloud. You can view the logs in the built-in workbooks and start building queries in Log Analytics to investigate the data. We recommend installing the Log Analytics agent for Windows or Linux using Azure Policy.Īfter your Arc-enabled servers are connected, your data starts streaming into Microsoft Sentinel and is ready for you to start working with. Alternatively, if you plan to monitor the machines with Azure Monitor for VMs, instead use the Enable Azure Monitor for VMs initiative to install and configure the Log Analytics agent. If the agent is not installed, it automatically deploys it using a remediation task. Using this approach, you use the Azure Policy Deploy Log Analytics agent to Linux or Windows Azure Arc machines built-in policy to audit if the Azure Arc-enabled server has the Log Analytics agent installed. VM extensions can be managed using the following methods on your hybrid machines or servers managed by Azure Arc-enabled servers: This feature in Azure Arc-enabled servers allows you to deploy the Log Analytics agent VM extension to a non-Azure Windows and/or Linux server. ![]() ![]() Azure Arc-enabled servers supports deploying the Log Analytics agent using the following methods: For physical and virtual machines, you can install the Log Analytics agent that collects the logs and forwards them to Microsoft Sentinel. Microsoft Sentinel comes with a number of connectors for Microsoft solutions, available out of the box and providing real-time integration. Onboard Azure Arc-enabled servers to Microsoft Sentinel Your machine or server is connected to Azure Arc-enabled servers. Microsoft Sentinel enabled in your subscription. For more information about Log Analytics workspaces, see Designing your Azure Monitor Logs deployment. Prerequisitesīefore you start, make sure that you've met the following requirements:Ī Log Analytics workspace. Microsoft Sentinel provides a single solution for alert detection, threat visibility, proactive hunting, and threat response across the enterprise. This article is intended to help you onboard your Azure Arc-enabled server to Microsoft Sentinel and start collecting security-related events.
