</span></b></i><span style="background:white">This new guidance provides lessons learned from a tabletop exercise designed to help an organization accomplish the PNT Profile processes of identifying and</span> protecting systems, networks, and assets; detecting
and responding to an anomaly; and recovering from a disruption. The updated guidance also mentions network areas of consideration which were discovered during a pilot tabletop exercise and helps in the risk management approach with self-assessment questions
(recommendations and test plan) the network operators, Chief Information Officers (CIOs), and Chief Information Security Officers (CISOs) need to walk through to create their mitigation profile. </span><span style="font-family:"Arial",sans-serif;color:black"><o:p></o:p></span></p>

in enterprise networks and systems. The recommendations in this document were designed to be incorporated into current test plans and regular systems maintenance and are consistent with the PNT E.O. </span><span style="font-family:"Arial",sans-serif;color:black"><o:p></o:p></span></p>
