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.
