    Tune rule to exclude forwarded events. (#3790)

    Events containing "forwarded" as a tag may include host information
    that is not related to the host running elastic agent. This triggers
    false positive alerts. Examples include Entity Analytics integrations,
    Palo Alto GlobalProtect activity, and M365 Defender device events.
