Recently, mobile devices and wireless networks are more common for supporting human activities providing mobility
and flexibility. Mobile devices inside a wireless environment
contribute to make easily accessible and available the information. However, wireless environment is susceptible to vulnerabilities due to information which is propagated through the air and thus exposed to interception or theft. Mobile devices present some physical limitations such as little capacity of processing, memory and battery duration. These limitations are critical in wireless environment when non identified threats attack mobile devices. Intrusion Detection Systems (IDSs) specialized to mobile devices are necessary in order to identify intrusive behavior taking into account their physical limitations. In this paper, we propose an IDS for wireless networks and mobile devices. This proposal is an extension of Intrusion Detection System-Network Intrusion
Detection System based on Intelligent Agents (IDS-NIDIA).
