In cases of disasters and emergency scenarios, due to lack of networkinfrastructure, first-responders can build mobile ad hoc networks to send information.However, the communication in these situations can suffer long interruptions. Thispaper proposes a security management framework to dynamically configure andreconfigure emergency networks, with goal to adapt the use of security componentsaccording to management information received by decision-maker responsible entities.The security management model includes the definition of security levels, managementinformation base, protocol messages and events. The evaluations realized show anemergency network behavior with activation of security mechanisms if necessary.
