title: Disabling Windows Event Auditing

description: |
|
|
Detects scenarios where system auditing (ie: windows event log auditing) is disabled.
|
|
This may be used in a scenario where an entity would want to bypass local logging to evade detection when windows event logging is enabled and reviewed.
|
|
Also, it is recommended to turn off "Local Group Policy Object Processing" via GPO, which will make sure that Active Directory GPOs take precedence over local/edited computer policies via something such as "gpedit.msc".
|
|
Please note, that disabling "Local Group Policy Object Processing" may cause an issue in scenarios of one off specific GPO modifications -- however it is recommended to perform these modifications in Active Directory anyways.
