In the last few years, the performances of wireless technologies have increased tremendously thus opening new fields of application in the domain of networking. One of such fields concerns mobile ad hoc networks (MANETs) in which mobile nodes organise themselves in a network without the help of any predefined infrastructure. Securing MANETs is just as(More)
Application level intrusion detection systems usually rely on the immunological approach. In this approach, the application behavior is compared at runtime with a previously learned application profile of the sequence of system calls it is allowed to emit. Unfortunately, this approach cannot detect anything but control flow violation and thus remains(More)
In this paper we propose a distributed and modular architecture for an intrusion detection system (IDS) dedicated to mobile ad hoc networks (MANET). Our proposition relies on the use of local IDSs on each node of the MANET and on an agent based intra-IDS communication framework. It has been validated by a proof-of-concept prototype, which is presented in(More)
