"Who decides how the United States deploys information assets, the priority of emplacement of those assets and what actions are taken to secure the Global Information Grid (GIG) and those Joint and Service unique systems riding on it: the Services, the Geographic Combatant Commanders (GCCs), Joint Task Force--Global NetOps (JTF-GNO)? For the last few years that debate has raged in the Network Operations (NetOps) community with the pendulum swinging between a global vice Geographic CCDR [Combatant Commander ] focus. Imagine the following scenario. The United States announces the decision to deploy and begins flowing forces in support of an operation in XCOM's theater. Individual Services begin making decisions on how the information infrastructure will be emplaced to support the operation. An adversary begins to infiltrate key military systems supporting the deployment of military forces. While the adversary is unable to completely mask its efforts, the scope of the intrusion is underestimated as these incidents are all worked within Service channels. Connection requests begin flooding commercial websites, including those that support friendly logistics efforts, rendering them inoperative. XCOM takes action to change the Information Condition in its Area of Responsibility (AOR) affecting systems outside of its theater. A large number of viruses begin to wreck havoc on the Internet and quickly begin to infect Department of Defense (DoD) systems. Discussions begin within the JTF-GNO on whether or not to disconnect the military points of presence from the Internet but the Services raise concerns over the Department's ability to continue to conduct logistical operations with commercial vendors."
