This document explains the changes required to switch over and upgrade to MS Windows Event Logging XML - Security log source type to enable new Message Processing Engine (MPE) rules developed during the Log Source Optimization (LSO) project.
Prerequisites
Support for ADFS Events
Log Source Stabilization (LSS) does not support ADFS Events with the updated MPE rules and log processing policy (LogRhythm Default v2.0). ADFS Events are supported separately with MS Windows Event Logging XML - ADFS. If you are using Microsoft Active Directory Federation Services (ADFS) and streaming ADFS logs through Windows Security log source types, we recommend using log source virtualization to stream MS Windows Event Logging XML - ADFS log messages.
For more information, see Log Source Virtualization.
