falsepositives:
    - VPN Tunnel being modified or deleted may be performed by a system administrator.
    - Verify whether the user identity, user agent, and/or hostname should be making changes in your environment.
    - VPN Tunnel modified or deleted from unfamiliar users should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
