Solution direction Solution direction • 6 mobile satellites units: • � 9.000,00 total non-recurring costs • � 20,00 per CERT is charged • Total of � 1.440,00 per year • In case the Emergency Network is used, the costs of calling by satellites phone are � 1,00 per minute
Deployment Deployment � To deploy an Emergency Network, the following steps have to be taken: 1. Organize a meeting with at least 2 CERTs 2. Create agreements on how the network is set up 3. Describe these agreements in a communication plan 4. Connect all participating CERTs to the satellite network 5. Add all CERT names and numbers to the communication plan 6. Update and distribute the communication plan on a frequent basis 7. Get more CERTs interested to participate in the arisen Emergency Network; start again at step 1.
Conclusion Conclusion � Which ways of communication can be used for the CERTs for mutual communication when the regular communications network (Internet) fails? � Satellite communication, best solution: • Completely separated network • Always worldwide available � No communication structure between CERTs in case of (partial) failure of the Internet: • Communication plan needed. � All procedures and (mobile) satellites phone numbers of the participating CERTs � No priority, CERTs have to take action now!
