Network threats and hazards are evolving at a high-speed rate in recent years. Many
mechanisms (such as firewalls, anti-virus, anti-malware, and spam filters) are being used as …

Intrusion Detection Systems (IDSs) are one of the key components for securing computing
infrastructures. Their objective is to protect against attempts to violate defense mechanisms …

In this paper, we critically review the issue of information fusion for computer security, both in
terms of problem formulation and in terms of state-of-the-art solutions. We also analyze main …

Managing raw alerts generated by various sensors are becoming of more significance to
intrusion detection systems as more sensors with different capabilities are distributed …

This paper is focused on detecting and analyzing the Distributed Denial of Service (DDoS)
attacks in cloud computing environments. This type of attacks is often the source of cloud …

Network security investigations pose many challenges to security analysts attempting to
identify the root cause of security alarms or incidents. Analysts are often presented with …

Cloud computing is a new business model, which represents an opportunity for users,
companies, and public organisations to reduce costs and increase efficiency, as well as an …

Wireless communications are vulnerable to certain number of cyber-attacks and intrusion
attempts due to the intrinsic openness of the communication channel. Virtual jamming attack …

Abstract Self-Organizing Maps (SOMs) are among the most well-known, unsupervised
neural network approaches to clustering, which are very efficient in handling large and high …

Intrusion analysis and incident management remains a difficult problem in practical network
security defense. The root cause of this problem is the large rate of false positives in the …
