Abstract:
Storage area networks is among the solutions that have been deployed in most enterprise information systems through the world by ensuring the processing of corporate data taking benefit of the high speed and the separation of provided services from processed data. Due to the great need of such infrastructures, a wireless connectivity have been added to these networks in order to ensure more flexibility and mobility for interconnected components in order to deal with environment constraints in addition to advanced security strategies defined for critical services and data and that have lead to a new kind of networks called wireless storage area networks. Such emerging networks integrate in most cases transaction- based applications that are exposed to several security threats that aim to prevent the correct processing of transactions and engender damage to interconnected components. In this paper, we propose a novel intrusion tolerant transaction management model for wireless storage area networks. The proposed model defines the secure flex transaction concept and is based on intrusion and detection strategy and compensability feature to manage transactions in WSAN either if this environment is compromised. Moreover, this model uses the Predicate Transition Net as a tool to control the executability of secure flex transactions. In order to illustrate the behavior of the proposed model and their security capabilities, a case study is defined for a transaction-based e-payment service for an online commerce company integrated in a monitored wireless storage area network that is exposed to a set of security attacks.
