Intrusions Detection System Based on Ubiquitous Network Nodes
  Ubiquitous computing allows to make data and services within the reach of users anytime and anywhere. This makes ubiquitous networks vulnerable to attacks coming from either inside or outside the network. To ensure and enhance networks security, several solutions have been implemented. These solutions are inefficient and or incomplete. Solving these challenges in security with new requirement of Ubicomp, could provide a potential future for such systems towards better mobility and higher confidence level of end user services. We investigate the possibility to detect network intrusions, based on security nodes abilities. Specifically, we show how authentication can help build user profiles in each network node. Authentication is based on permissions and restrictions to access to information and services on ubiquitous network. As a result, our idea realizes a protection of nodes and assures security of network.
