An adaptive security management model for emergency networks

In disasters and emergency scenarios, due to a lack of network infrastructure, first-responders can build mobile ad hoc networks to send information and help disaster response coordination. However, the communication in these situations can suffer from long interruptions. This paper proposes a security management framework to dynamically configure or reconfigure emergency networks, in order to adapt the use of security components according to management information received by the decision-maker entities. The security management model includes the definition of security levels, the management information base, protocol messages and events. The emergency network activates the security mechanisms only when necessary, which avoid attacks effects and save resources.
