چکیده

This paper describes b-v model which is enhanced version of the negative selection algorithm (NSA). In contrast to formerly presented approaches, binary and real-valued detectors are incorporated. The reason behind developing this hybrid is willingness to overcome the scalability problems, which are a key problem, when only one type of detectors is used. Although high-dimensional datasets are a great challenge for NSA, however, equally important are quality of generated detectors and duration of learning as well as classification stages. Thus, also there are discussed various versions of b-v model to increase its efficiency. Versatility of proposed approach was intensively tested by using popular testbeds concerning domains like computer’s security (intruders and spam detection), recognition of handwritten words, etc.

A hybrid approach for database intrusion detection at transaction and inter-transaction levels

Nowadays, information plays an important role in organizations. Sensitive information is often stored in databases. Traditional mechanisms such as encryption, access control, and authentication cannot provide a high level of confidence. Therefore, the existence of Intrusion Detection Systems in databases is necessary. In this paper, we propose an intrusion detection system for detecting attacks...

BeeID: intrusion detection in AODV-based MANETs using artificial Bee colony and negative selection algorithms

Mobile ad hoc networks (MANETs) are multi-hop wireless networks of mobile nodes constructed dynamically without the use of any fixed network infrastructure. Due to inherent characteristics of these networks, malicious nodes can easily disrupt the routing process. A traditional approach to detect such malicious network activities is to build a profile of the normal network traffic, and then iden...

An enhanced Hybrid Anomaly-based Detection Approach

During the last decade, Intrusion Detection Systems (IDSs) have played an important role in defending critical computer systems and networks from cyber-attacks. Anomaly detection techniques have received a particularly great amount of attention because they offer intrinsic ability to detect unknown attacks. In this paper, we propose an enhanced hybrid anomaly detection approach based on negativ...

A hybrid approach for efficient anomaly detection using metaheuristic methods

Network intrusion detection based on anomaly detection techniques has a significant role in protecting networks and systems against harmful activities. Different metaheuristic techniques have been used for anomaly detector generation. Yet, reported literature has not studied the use of the multi-start metaheuristic method for detector generation. This paper proposes a hybrid approach for anomal...
