Note: AMA will replace the Microsoft Monitoring Agent (MMA), due for deprecation on August 31, 2024.Ĭheck out the Top 10 Security Events to Monitor in Azure Active Directory and Office 365 in this eBook. Windows Forwarding Event (WEF): Public preview.Linux Syslog CEEF (Common Event Format): Private preview ( sign-up link).Windows DNS logs: Private preview ( sign-up link).The sources in preview at the time of writing might be generally available when you read this text: AMA supports several data sources and events for use with Microsoft Sentinel. With AMA, you can filter VM security logs. This allows for further reduction in ingested volume, as it’s possible to select only the logs required for security monitoring.įigure 1: Windows event filtering in Microsoft Sentinel. Windows event filtering: you can use XPATH queries to filter specific Windows events, like 4624,4625 (see configuration window in Figure 1). ![]() This allows for centrally managed ‘log profiles’ to ensure valid configuration throughout the infrastructure. Scope of monitoring: centrally configure log collection for different sets of VMs, including different sets of data.Multi-homing support: you can send data from Windows and Linux VMs to multiple Log Analytics workspaces, for example, to monitor non-security relevant data for a VM, like performance metrics to understand hardware utilization, in a dedicated workspace.The AMA collects monitoring data from virtual machines, independent from the VM host: Azure, on-premises, or multi-cloud environments. This article explores how to increase cost efficiency within Microsoft Sentinel by leveraging Log Analytics capabilities. As described here, several ways exist to reduce costs by ensuring that Sentinel only processes relevant logs. Microsoft charges to ingest data into Sentinel on a per GB basis. For a more detailed overview of the capabilities that Microsoft Sentinel offers, review this Microsoft Docs article.ĭepending on the size of the environment and the services deployed, log ingestion, as well as storage, can represent a big portion of the cost of Microsoft Sentinel. to help organizations detect and respond to security threats within their IT environment. It collects security-related data from different sources like firewalls, servers, PaaS, etc. Microsoft Sentinel is a cloud-native SIEM (Security Information and Event Management) and SOAR (Security Orchestration and Automated Response) solution.
