The intrinsic vulnerable characteristics of mobile networks, without a fixed underlying infrastructure, are the low rejection to unauthorized intrusions. In this paper we focus on a Grid based Intrusion Detection System (G-IDS). We present a new architecture that use the basic principles of the Grid computing and apply them to the intrusion detection mechanisms, in order to protect networks characterized by the constantly changing of the topology. Our research is not focused on new algorithms or products capable to solve the security problem in Ad hoc networks: our goal is to define a process and software architectures that minimize the security risk in not centralized wireless networks, acting the principle that the wireless network security is not a “product” but a well defined “process”. On the basis of the defined architecture we have implemented a prototype of Grid based IDS Agent that validates our thesis. The prototype is realized integrating two open-source technologies: GLOBUS of the GLOBUS Alliance and CoMo of Intel Corporation.

INTRODUCTION Wireless ad-hoc networks have limited utilization of an underlying fixed infrastructure because many network functionalities are included in the mobile nodes that “join” on the fly and create a network on their own. The lack of centralized network management functionality makes it very vulnerable to an adversary malicious attack. Security in wireless ad-hoc networks is particularly difficult to achieve, notably because of the limited physical protection of each node, the sporadic nature of connectivity, the absence of a certification authority, and the lack of centralized monitoring or management unit. In this scenario firewalls didn’t keep out network attackers: traditional IDS [1][2] raises only alerts messages that didn’t keep network safe. In this paper we focus on a Grid [3] based Intrusion Detection
