Too many Splunk Forwarder Events in base Sysmon Config

[tbalz2319]

Hello,

We are using this config and really like it but we have noticed their are way too many Splunk forwarder events event-id 11

and the image is Image="C:\Program Files\SplunkUniversalForwarder\bin\splunk-winevtlog.exe"

is their anyway I can exclude all of these? Do we need to run specific powershell commands ?

@tbalz2319 you can exclude these by creating new .xml file in 11_file_create folder and running the merge script. The content of the file can be something like this

<Sysmon schemaversion="4.30">
    <EventFiltering>
        <RuleGroup name="" groupRelation="or">
            <FileCreate onmatch="exclude">
                <Image condition="begin with">C:\Program Files\SplunkUniversalForwarder\bin\</Image>
            </FileCreate>
        </RuleGroup>
    </EventFiltering>
</Sysmon>

Just tried this and it did not seem to work,

The Splunk forwarder events for event-id 11 are still flowing non-stop

Do we need to specify a RulgeGroup name?
