An Implementation of Intrusion Detection System Using Genetic Algorithm
Nowadays it is very important to maintain a high level security to ensure
safe and trusted communication of information between various organizations.
But secured data communication over internet and any other network is always
under threat of intrusions and misuses. So Intrusion Detection Systems have
become a needful component in terms of computer and network security. There are
various approaches being utilized in intrusion detections, but unfortunately
any of the systems so far is not completely flawless. So, the quest of
betterment continues. In this progression, here we present an Intrusion
Detection System (IDS), by applying genetic algorithm (GA) to efficiently
detect various types of network intrusions. Parameters and evolution processes
for GA are discussed in details and implemented. This approach uses evolution
theory to information evolution in order to filter the traffic data and thus
reduce the complexity. To implement and measure the performance of our system
we used the KDD99 benchmark dataset and obtained reasonable detection rate
Hierarchical Design Based Intrusion Detection System For Wireless Ad hoc Network
In recent years, wireless ad hoc sensor network becomes popular both in civil
and military jobs. However, security is one of the significant challenges for
sensor network because of their deployment in open and unprotected environment.
As cryptographic mechanism is not enough to protect sensor network from
external attacks, intrusion detection system needs to be introduced. Though
intrusion prevention mechanism is one of the major and efficient methods
against attacks, but there might be some attacks for which prevention method is
not known. Besides preventing the system from some known attacks, intrusion
detection system gather necessary information related to attack technique and
help in the development of intrusion prevention system. In addition to
reviewing the present attacks available in wireless sensor network this paper
examines the current efforts to intrusion detection system against wireless
sensor network. In this paper we propose a hierarchical architectural design
based intrusion detection system that fits the current demands and restrictions
of wireless ad hoc sensor network. In this proposed intrusion detection system
architecture we followed clustering mechanism to build a four level
hierarchical network which enhances network scalability to large geographical
area and use both anomaly and misuse detection techniques for intrusion
detection. We introduce policy based detection mechanism as well as intrusion
response together with GSM cell concept for intrusion detection architecture.Comment: 16 pages, International Journal of Network Security & Its
