Intrusion Detection Systems (IDS) are among the fastest growing technologies in computer security domain. These systems are designed to identify/ prevent any hostile intrusion into a network. Today, variety of open source and commercial IDS are available to match the users/ network requirements. It has been accepted that the open source intrusion detection systems enjoys more support over comme...

The Internet is being used by increasing number of users day by day. Security is a big issue for all networks in today’s enterprise environment. The security of a computer is compromised when an intrusion takes place. Many methods have been developed to secure the network infrastructure and communication over the Internet, among them the use of encryption algorithm, virtual private network and ...

With the growing Information Systems and Network technologies, security threats over the systems have also become common. Providing a security mechanism to detect such threats has become an inevitable part of Information Systems. Distributed Denial of Service (DDoS) attack is one of the most common attacks which are done in a co-ordinated manner. Hence, we need a Distributed Intrusion Detection...

Machine learning systems are deployed in many adversarial conditions like intrusion detection, where a classifier has to decide whether a sequence of actions come from a legitimate user or not. However, the attacker, being an adversarial agent, could reverse engineer the classifier and successfully masquerade as a legitimate user. In this paper, we propose the notion of a Proactive Intrusion De...

One key feature of intrusion detection systems is their ability to provide a view of unusual activity and issue alerts notifying administrators and/or block a suspected connection. Intrusion detection is a process of identifying and responding to malicious activity targeted at computing and networking resources. Over the past decade, the field of IDS has been driven into overdrive by the explos...

Over the recent years, IP and email spoofing gained much importance for security concerns due to the current changes in manipulating the system performance in different online environments. Intrusion Detection System (IDS) has been used to secure these environments for sharing their data over network and host based IDS approaches. However, the rapid growth of intrusion events over Internet and ...
