DL-based defense against polymorphic network attacks
Network security is of vital importance in our world dominated by internet systems. These systems are vulnerable to large-scale rapidly evolving attacks by sophisticated cyber attackers who can have an upper edge over the defensive systems. Artificial Intelligence (AI) based intrusion detection …

Defense against network attacks using game theory
… has become ubiquitous, the risk posed by network attacks has greatly increased. Network attacks have been used to achieve a wide gamut of objectives ranging from overloading a website to accessing classified data. Effective defense against such attacks is a critical research area. In this …

Detecting network attacks using high-resolution time series
Research in the detection of cyber-attacks has sky-rocketed in the recent past. However, there remains a striking gap between usage of the proposed algorithms in academic research versus industrial applications. Leading researchers have argued that efforts toward the understanding of proposed …

Computer Network Attacks and the Contemporary Jus ad Bellum
… contemplated in this thesis. However, Computer Network Attacks took a backseat for much of the first decade of the 21st century while international terrorism was the most popular topic of discussion in the international law governing the use of force, commonly known by its Latin name the jus ad …

Mitigation of Different Network Attacks and Optimization in Software Defined Network
Cyber attacks are growing with the increase in internet usage. There are several types of network attacks including volumetric and non-volumetric attacks.In a volumetric attack, the target resource is taken down with a huge amount of traffic. Distributed denial-of-service (DDoS) and transit-link …

Robustness: A New US Cyber Deterrence Strategy
<p>The growing trend of computer network attacks provokes the necessity for a comprehensive cyber deterrence strategy to deter aggressors from attacking U.S. critical infrastructure. The current U.S. cyber deterrence strategy based on punishment is ineffective in deterring aggressors as evidenced …

An entropy-based approach to network attack classification with deep neural network
Detecting and classifying attacks on computer networks is a significant challenge for network providers and users. This thesis project builds a deep neural network to detect and classify network attacks. Our approach based on the hypothesis that each type of network attacks generates a …

Preemptive Detection of Cyber Attacks on Industrial Control Systems
Industrial Control Systems (ICSes), networked through conventional IT infrastructures, are vulnerable to attacks originating from network channels. Perimeter security techniques such as access control and firewalls have had limited success in mitigating such attacks due to the frequent updates …

Mining intrusion detection alert logs to minimise false positives & gain attack insight
… understanding the security state of a computer network, often defined by its current exposure and resilience to network attacks. Thus, the study of understanding network attacks through event analysis is a fast growing emerging area. In comparison to its first appearance a decade ago, the …

Near real-time threat assessment using intrusion detection system's data
… since the late sixties. In recent computer networks, the use of different types of Intrusion Detection Systems (IDS) is considered essential and in most cases mandatory. Major improvements have been achieved over the years and a large number of different approaches have been developed and …

Finding multi-step attacks in computer networks using heuristic search and mobile ambients
… and continuous identification of possible attacks in computer networks. This is complicated due to the complexity and size of networks, and due to the fact that usually network attacks are performed in several steps. This thesis proposes an approach called MsAMS (Multi-step Attack Modelling …

Wi-Fi attack mitigation: analysis, design and implementation
Wi-Fi network provides local area network with mobility, convenience and low cost. At the same time, it suffers several typical security problems, such as being unsafe and more vulnerable than traditional wired network. The shared nature of wireless medium makes wireless network attacks easily to …
