"The U.S. Insider Threat Classification Guide, hereafter referred to as the 'Guide,' is the Executive Branch's standard reference for derivative classification determinations on insider threat activities. The Guide provides a baseline for protecting United States Government (USG) policy associated with insider threat activities and shall be used in concert with existing agency or program level classification guidance concerning insider threats, as appropriate. The Guide provides minimum standards for classification of insider threat information and does not supersede any agency's Original Classification Authority. Nothing in this Guide prohibits agencies from establishing classification guidance that is more restrictive than the citations contained in this Guide, as necessary to protect sensitive sources or methods. If applicable, users should refer to their respective agency classification guides first before applying guidance contained herein."
