INTRUSION DETECTION SYSTEM FOR MANET

IAEME PUBLICATION, 2014

MANET which means Mobile Ad hoc Networks is popular because it requires no network infrastructure for the mobile nodes within the network to communicate. Any node can join or leave the network independently. The important features of MANET are dynamic topology, self-configuring, peer to peer architecture, use of wireless medium and so on. Due to the dynamic infrastructure, MANET provides high flexibility that attracts them to many application as well as prone to security threats. Many of the vulnerability in MANET are hard to detect. Even though the IDS was used as a security measure in wired network, researchers had explore the IDS as the security solution for the mobile ad hoc network In this paper, we study the different IDS techniques that can be applied on MANET. We will first describe briefly about the different types of security threats and then describe the IDS technique to counter the attacks.

A mobile ad hoc network is an infrastructure less network which is prone to various malicious attacks when incorporated in applications. It is a dreadful task for attaining security to the greatest degree in MANET. This is awaited to the diverse characteristics of mobile ad hoc networks which unlike from well-established infrastructure network. In order to overcome this security challenges the Intrusion detection systems have been deployed in the ad hoc network. In this paper we focus on surveying heterogeneous intrusion detection systems used in MANET for defending various attacks. Keywords— Mobile Ad hoc Network; IDS; Routing protocols; Attacks

With the progression of computer networks extending boundaries, Mobile ad hoc network (MANET) has emerged as a new frontier of technology to provide any where, any time communication. Due to its deployment nature, MANETs are more vulnerable to malicious attack. The absolute security in the mobile ad hoc network is very hard to achieve because of its fundamental characteristics, such as dynamic topology, open medium, limited power and limited bandwidth. The Prevention methods like authentication and cryptography techniques alone are not able to provide the security to these types of networks. Therefore, efficient intrusion detection must be deployed to facilitate the identification and isolation of attacks. In this paper we have surveyed various intrusion detection techniques in MANET and analyzed their fruitfulness.

In the recent decades the mobile wireless communication becomes more attractive because of its applications in many fields. Moving from the wired communication to wireless communication, the security is the most important property to consider. Specifically in the mobile environment it has the vulnerability, because of its portability and scalability. The mobile ad hoc wireless communication has characteristics such as open medium, distributed environment and changing topology, it makes the network into most vulnerable to the attackers to make the intrusion. The attackers (intruders) can easily enter into the network and compromises the network to behave in the favours of his choice. The Mobile Ad hoc NETwork (MANET) should have the capability to detect such intrusion (attacks) and remove it. To survive the MANET from such intrusion, an Intrusion Detection System (IDS) should be enhanced to the MANET, which can efficiently identify the attacks of the intruders. In this paper it is discussed about various intrusion detection mechanisms and techniques for the MANET to detect the intrusion and intruders

The feasibility of mobile ad hoc networks (MANETs) is gaining popularity widely. Due to its fundamental characteristics like dynamic topology, open medium, absence of infrastructure, limited power and limited bandwidth, these networks are more prone to malicious attacks. The prevention methods like encryption and cryptography are not sufficient to make them secure. The reason behind this is that these techniques focus on how to protect the data but do not take any action against the intruder. Therefore some detection mechanism must be deployed to facilitate the identification and isolation of attacks before an attacker breaches the system. This paper presents the existing architectures for intrusion detection systems (IDS) along with intrusion detection techniques in MANETs and their comparison.

— This Paper presents a coherent survey on to detect the misbehaving node in Mobile Ad hoc Network (MANET) with the intent of serving as a quick reference to the current research issues in MANET. A mobile ad-hoc network is an infrastructure less network, that is self-configuring mobile nodes connected by wireless links. The open medium and the decentralized property of these nodes relay on each other to store and forward packets. Most of the proposed MANET protocols do not address security issues. Furthermore, MANETs are highly vulnerable for passive and active attacks because of their open medium, rapidly changing topology, lack of centralized monitoring. The encryption and authentication solution, which are considered as the first line of defence, are no longer sufficient to protect MANETs. Therefore, Intrusion Detection System (IDSs) is needed to be the second line of defence to protect the network from Security problems. In recent years, the security issues on MANET have become ...

In recent years, the security issues on MANET have become one of the primary concerns. The MANET is more vulnerable to be attacked than wired network. These vulnerabilities are nature of the MANET structure that cannot be removed. As a result, attacks with malicious intent have been and will be devised to exploit these vulnerabilities and to cripple the MANET operation. Attack prevention measures, such as authentication and encryption, can be used as the first line of defense for reducing the possibilities of attacks. However, these techniques have a limitation on the effects of prevention techniques in general and they are designed for a set of known attacks. They are unlikely to prevent newer attacks that are designed for circumventing the existing security measures. For this reason, there is a need of second mechanism to "detect and response" these newer attacks, i.e. "intrusion detection". This paper aims to explore and to classify current techniques of Intrusion Detection System (IDS) aware MANET. To support these ideas, a discussion regarding attacks, IDS architectures, and researches achievement on MANET are presented inclusively, and then the comparison among several researches achievement will be evaluated based on these parameters. By this way, several existing security problems on MANET can be probed quickly for future researches.

"Since there is no infrastructure in mobile ad hoc networks, each node must rely on other nodes for cooperation in routing and forwarding packets to the destination. Intermediate nodes might agree to forward the packets but actually drop or modify them because they are misbehaving. The simulations in show that only a few misbehaving nodes can degrade the performance of the entire system. There are several proposed techniques and protocols to detect such misbehavior in order to avoid those nodes, and some schemes also propose punishment as well. It is very difficult to design once-for intrusion detection techniques. Instead, an incremental enhancement strategy may be more feasible. A secure protocol should at least include mechanisms against known attack types. In addition, it should provide a scheme to easily add new security features in the future. Due to the importance of MANET routing protocols, we focus on the detection of attacks targeted at MANET routing protocols This includes WatchDog and Pathrater approach. A watchdog identifies the misbehaving nodes by eavesdropping on the transmission of the next hop. A path rater then helps to find the routes that do not contain those nodes. "

Ad Hoc Network due to its infrastructure less ability. It has been providing lots of benefits in the field of communication and has changed the word into Global village. It has many features for example deployment facility, limited resources, dynamic topology and physical insecurity, the chances of attack increased than any other network. And due to dynamic topology, no static solution is applicable. There are two defense mechanism that can reduce the attack. First includes cryptography etc. If this defense is broken then intrusion detection system helps to reduce the attack ratio. In this survey paper, intrusion detection system taxonomy has been observed through different point of view. But the IDS detection mechanism has been elaborated in detail. And a comparison has been performed between the detection mechanism been used so far. Finally, we concluded useful information related to different mechanism and which mechanism has been used the most and performed well.
