Secure Mobile Networking
Demonstration


  A Technical Overview of the
    Network and Data Flow
    (Dave Stewart, Terry Bell and Will Ivancic)



                                                  1
Mobile-Router Advantages
   Share wireless and network resources with
    other organizations
       $$$ savings
   Set and forget
       No onsite expertise required
       However, you still have to engineer the network
   Continuous Connectivity
       (May or may not be important to your
        organization)
   Robust
       Dynamic (Secondary) Home Agent
                                                          2
Scenario
   Mobile command center deployed at
    hostage situation.
   Satellite connectivity needed for
    reachback to Internet from mobile
    command center.




                                        3
Network Concept
   OSHP Bus is remote control center
    during emergency situations
       Reachback to the Internet can be provided
        in a number of ways including satellite,
        rapidly installed land lines (T-1) or G3/G4
        Cellular
   Demonstration Room in Patrol Academy
    represents OSHP Headquarters
   Patrol Cars are the mobile networks
                                                 4
Requirements
   Rapidly Deployable – no onsite expertise
    required
   Contact between patrol cars and remote
    command center are of greatest importance.
   Desire to have voice, data, and – given
    sufficient bandwidth – video between the
    patrol cars and the bus and/or headquarters.
   Desire to monitor and control sensors and
    cameras remotely from the remote command
    center or headquarters.
                                              5
Full Scale Deployment
   Data would NOT flow from the mobile
    command center to Headquarters via a
    private 802.11 link.
   Instead, encrypted data would come
    into Headquarters via the Internet.

Demonstration Caveats
   To ease demonstration setup and
    configurations, all data from the mobile
    networks passes through the wireless
    encryptor.
   No encrypted data flows from the Internet
    directly to Headquarters
   To ease configurations, mobile units
    communicate to each other via Headquarters
    (probably via the remote control center in a
    real deployment).
