Abstract:

The growing connectivity of cyber-physical systems (CPSes) has led to an increased concern over the ability of cyber-attacks to inflict physical damage. Current cybersecurity measures focus on preventing attacks from penetrating control supervisory networks. These reactive techniques, however, are often plagued with vulnerabilities and zero-day exploits. Embedded processors in CPS field devices often possess little security of their own, and are easily exploited once the network is penetrated. In response, researchers at Georgia Tech and Virginia Tech have proposed a Trustworthy Autonomic Inte

Abstract:

This dissertation investigates and introduces novel algorithms, theories, and supporting frameworks to significantly improve the growing problem of Internet security. A distributed firewall and active response architecture is introduced that enables any device within a cyber environment to participate in the active discovery and response of cyber attacks. A theory of semantic association systems is developed for the general problem of knowledge discovery in data. The theory of semantic association systems forms the basis of a novel semantic path merger packet classification algorithm. The theo

Abstract:

Critical infrastructures include sectors such as energy resources, finance, food and water distribution, health, manufacturing and government services. In recent years, critical infrastructures have become increasingly dependent on ICT; more interconnected and are often, as a result, linked to the Internet. Consequently, this makes these systems more vulnerable and increases the threat of cyber-attack. In addition, the growing use of wireless networks means that infrastructures can be more susceptible to a direct digital attack than ever before. Traditionally, protecting against environmental

Abstract:

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 required by standard computing platforms, third-party hardware and embedded process controllers. The high level of human-machine interaction also aids in circumventing perimeter defenses, making an ICS susceptible to attacks such as reprogramming of embedded controllers.

Abstract:

This thesis examines the intersection of law and technology in the context of cyber attacks and international law on the use of force. It is argued that the law embodies an ontologically constrained view of violence which limits its capacity to regulate cyber attacks. As a means of overcoming these constraints, this thesis draws on Luciano Floridi’s information ethics to develop an informational approach. This involves depicting the state as an information entity and reconceptualising violence through the concept of entropy. Therefore, by updating the law with an informational ontology, it is

Abstract:

A study on countermeasures against coordinated cyber-attacks (CCA) towards power grid systems has been carried out. A coordinated cyber-attack is a cyber-based attack where multiple attackers use multiple attack-mechanisms towards multiple targets in a coordinated fashion. The coordination is based on that the different attack-mechanisms help each other in attacking the target. A CCA is made up of different stages where each stage consists of a number of attack-mechanisms and together have a certain purpose. The different stages are used to systematically advance towards its goal, which is to

Abstract:

The 2014 cyber attack on Sony Pictures Entertainment is an example of a disruptive event where a nation state utilized cyber tools in order to coerce a target into changing their course of action. Cyber attacks, something that might be perceived as a looming futuristic threat, became reality for Sony and its employees under the course of a few months in late 2014. The coercer’s attempt to change the behavior of the company eventually failed and North Korea who was attributed as coercer was imposed with new sanctions. This paper takes on the task of evaluating the Sony case against both the tra

Abstract:

State estimation plays an essential role in the monitoring and control of power transmission systems. In modern, highly inter-connected power systems the state estimation should be performed in a distributed fashion and requires information exchange between the control centers of directly connected systems. Motivated by recent reportson trojans targeting industrial control systems, in this paper we investigate how a single compromised control center can affect the outcome of distributed state estimation. We describe five attack strategies, and evaluate their impact on the IEEE 118 benchmark po

Abstract:

To address the arising Cyber Security threats against SCADA-based Critical infrastructure, the security research community have identified the application of Intrusion Detection and IA as an ideal security measure for such systems. The research presents a cyber-attack classification for critical infrastructure, to identify the cyber-attack landscape for critical infrastructure attacks. To further aid in the development and evaluation of AI using intrusion detection, the thesis presents a SCADA cyber-attack generation framework. The cyber-attack generation framework provides a collection of alg

Abstract:

Actualment, l’evolució tecnològica, particularment en el camp del espai cibernètic, ha donat lloc a reptes seriosos per la seguretat dels Estats. Ocasionalment, els atacs cibernètics tenen els mateixos efectes destructius que les armes militars. Donada la manca d’acords entre Estats per tal de constituir noves normes sobre el ciberespai, la comunitat internacional ha provat de fer front als atacs cibernètics mitjançant l’aplicació per analogia del Dret Internacional existent. En el primer capítol, el nostre estudi inicia amb una aproximació històrica al principi de la prohibició de l’ús de la

Abstract:

Malicious cyber-attacks, those cyber-attacks which do not rise to the level of force in international law, pose a significant problem to the international community. Attributing responsibility for malicious cyber-attacks is imperative if states are to respond and prevent the attacks from continuing. Unfortunately, due to both technical and legal issues attributing malicious cyber-attacks to the responsible state or non-state actor is difficult if not impossible in the vast majority of attacks. Even if an injured state may recursively trace the malicious cyber-attack to the responsible IP addre
