Mobile agent has been adopted in the field of intrusion detection system primarily to resist against distributed attacks and makes it more flexible and scalable. Mineral models has been proposed. However, common shortcoming exist with these models like dependency on a central node or hierarchical decision making which cause to single point of failure. increasing the load of network and disability to detect sophisticated attacks. A central coordinator mobile agents architecture and neighborhood watch in virtual areas are two potential concepts that could overcome the limitation of existing models. In this work a coordinator association approach for mobile agent based IDS will be presented. The merits of this approach will be compared against existing IDSs and implementation and configuration issues will be discussed detail.
