LSO - MS Windows Event Logging XML - Security

This document explains the changes required to apply new Message Processing Engine (MPE) rules developed during the Log Source Optimization (LSO) project for the MS Windows Event Logging XML - Security log source type. 

Prerequisites

  • Download and apply the Knowledge Base. For more information, see KB Synchronization Settings for LSO.

  • Enable the new MPE rules in the LogRhythm System Monitor.

    • Select log source type MS Windows Event Logging XML - Security.

      Ensure that you select the the log source type with "XML" in the name.

    • Enable log processing policy LogRhythm Default v2.0.

    For details on how to enable LogRhythm Default v2.0, see Apply LogRhythm Default v2.0 on a Log Source.

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.


Supported Log Messages

The following table lists the log message types supported in the current MPE rules. Each linked page contains detailed information on parsing changes and new log processing settings.

Log Processing Policy Updates

This section details log processing policy updates made to AIE Rules, system reports and templates, tails, and investigations as part of LSO.

Changes made for LSO may impact downstream analytical components in LogRhythm. It is recommended that you review MPE policies, parsing rules, and log processing settings to assess the potential impact to your environment and custom analytical components, including saved investigations, dashboards, and fields mapped with SmartResponse Plugins.
