4The network as a Battlespace Avenues ofApproachCNDCNEFirewall &GuardIntrusionSensorRef: LCol R. Knight, CFIOG, DNDLand, Sea and Air activities are predicated increasingly on networksAn attack on a network can dramatically upset operations. Currently, it is difficult and time consuming to understand the effect of a network attack on the mission and to plan an appropriate response.Must maintain network situational awareness
5Network Situational Awareness Knowing the level of threats and the current status of all network assets supporting military operations.IT Infrastructure (circuits, hardware, software)Defensive posture;Security events (C, I, A, etc) ;Military Operations;Interdependencies.

13NOC View3 users report that a military Web site providing weather maps is not responding.Monitoring tool alerts of sudden surge in traffic on a base LAN.Intrusion detection system alerts of intense scanning activities on a subnet.NOCSo what ?
14Operational Command View Option 1:Silos information report :SERVICES:3 users report that a military Web site providing weather maps is not responding.;PERFORMANCE:Monitoring tool alerts of sudden surge in traffic on a base LAN.SECURITY:Intrusion detection system alerts of intense scanning activities on a subnet.OROption 2:Integrated information report:IMPACT:Weather services to all deployed ships is inaccessible.CAUSE:One vulnerable IIS server infected by SQLSlammer worm. Infected server is scanning surrounding hosts to propagate the worm. This scanning activity creates a denial of service for all servers on subnet.Cmd
15How to get option 2, and quicker? Integrate dataIT infrastructureSecurity eventsMilitary operationsCommon source of information to achieve Network Situational Awareness at the NOC and to answer the “So what?”Improve decision makingFaster (option space Vs time)Quality (support risk acceptance option)PrioritizeNOC
16SharingShare with the NOC sub-units to improve their own processes by giving them more context.Tactical decisions may require strategic level information.Let others look at it in a way meaningful to them (UDOP: User Defined Operating Picture)NOC
17Joint Network Defence & Management System (JNDMS) This is a high level view of the JNDMS concept.There are 3 types of input data.The first one is security events data. This could include alerts from network intrusion detection systems, alerts from network managements tools, and intelligence reports.The second type is military operations data. This is data on operations and their associated IT services and assets.The third type of input data is IT infrastructure data. This is the topology and the configuration.The integration creates contextual data inside of the JNDMS.The output is network situational awareness, which is knowledge used for decision support.

20Contributing to Ops Commander’s COP CmdShould we? We think so!How?Sharing data: Requires compatible data sets.C2IEDM? Possibly, needs extension.How to display?Does it imply geospatial map? (not always relevant, symbology, clutter issue)Need to capture reliance of military operations on cyber assets.At what level of details?Export snapshot of NOC viewe.g. a separate window in COP 21
