This article describes how to tune out Windows Filtering Platform (WFP) on LEM and on a Windows agent. WFP is a new application in Windows 7 and Windows 8 and Server 2008/2012 that logs firewall and IPsec related events to the System Security Log. These alerts represent accepted background alerts on LEM and consume additional resources on LEM while it processes these events. They are not necessary in an optimized LEM deployment.


  • All LEM versions
  • Windows 7, 8 and 8.1
  • Windows Server 2008, 2008 R2 and 2012


Modify the LEM Alert Distribution Policy

  1. Open LEM Console and log into your LEM Manager from the Manage > Appliances view.
  2. Click the gear icon next to your LEM Manager, and select Policy.
  3. Locate the alerts you want to disable by either browsing the Alert Taxonomy or using the search box under Refine Results.
    Note: You can locate all the alerts listed below by typing Windows Security in the search box.
  4. Tick or unmark the boxes in Console, Database, Warehouse or Rules, as appropriate.
    • Untick the Console box to prevent your LEM Manager from showing the alerts in your LEM Console.
    • Untick the Database box to prevent your LEM Manager from storing the alerts in your LEM database.
    • Untick the Warehouse box to prevent your LEM Manager from sending the alerts to an independent database warehouse.
    • Untick the Rules box to prevent your LEM Manager from processing the alerts against your LEM rules.
    • Tick any box to enable processing of the alerts for any of the four levels listed above. 
  5. Click Apply if you want to save your changes and keep working, or click Save if you want to save your changes and exit the Alerts Distribution Policy window.
