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)
The wireless links between the nodes together with the dynamic-network nature of ad hoc network, increases the challenges of design and implement intrusion detection to detect the attacks. Traditional intrusion detection techniques have had trouble dealing with dynamic environments. In particular, issues such as collects real time attack related audit data(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)
RÉSUMÉ. Nous présentons dans cet article une architecture modulaire pour un système de détection d’intrusions (IDS) dédié aux réseaux ad hoc. Cette architecture repose sur l’implantation d’IDS sur chaque nœud du réseau ad hoc. Ces IDS locaux communiquent par le biais d’agents mobiles. Les choix de conception ont été validés par un prototype qui est décrit(More)
