Machine-aided analysis of vote privacy using computationally complete symbolic attacker
… and authenticity in the presence of malicious attackers. Due to the complexities of cryptographic primitives, subtle nature of the security guarantees and asymmetry of communication over the internet, their design tends to be error-prone. Thus, formal methods are often used to establish whether …

A Measurement Approach to Understanding the Data Flow of Phishing From Attacker and Defender Perspectives
… picture of the data flow of phishing from both attacker and defender perspectives. First, from attackers' perspective, we want to know how attackers collect the sensitive information stolen from victims throughout the end-to-end phishing attack process. So we collected more than 179,000 …

Cyber-security Risk Assessment
… is human, and hence intelligent in nature. The attacker adapts to the situation, target environment, and countermeasures. Attack actions are also driven by attacker's exploratory nature, thought process, motivation, strategy, and preferences. Current security risk assessment is driven by …

Computational Resource Abuse in Web Applications
… through the browser creates an opportunity for attackers to abuse resources. Principally, the problem occurs when an attacker compromises a Web site and includes malicious code to abuse its visitor's computational resources. For example, an attacker can abuse the user's system networking …

Using VProbes for intrusion detection
… the same operating system (OS) as a potential attacker. Since an attacker will often be attempting to co-opt the OS, this leaves the IDS vulnerable to subversion by the attacker. While some systems escape this threat, they typically do so by running the OS inside a modified hypervisor. This …

Position Falsification Detection in VANET with Consecutive BSM Approach using Machine Learning Algorithm
… communications. However, if there is an inside attacker additional measures are necessary to ensure the correctness of the transmitted data. A basic safety message (BSM) is broadcasted by each vehicle in the network periodically to transmit its status. Position falsification is an attack where …

A database of computer attacks for the evaluation of intrusion detection systems
… realistic variance in the methods used by the attacker. The attacks included in the 1998 DARPA intrusion detection evaluation were developed to provide a reasonable amount of such variance in attacker methods, Some attacks occur in a single session with all actions occurring in the clear, while …

Defense against network attacks using game theory
… this thesis. The first scenario is that of the attacker carrying out a Distributed Denial of Service (DDoS) attack. The second scenario involves the attacker possessing the ability to carry out a number of different attacks such as Denial of Service (DoS), Dictionary attacks and Portscans. An …

Design and Analysis of Intrusion Detection Protocols in Cyber Physical Systems
… strength in response to environment changes in attacker strength and behavior. The end result is an energy-aware and adaptive IDS that can maximize the CPS lifetime in the presence of malicious attacks, as well as malicious, erroneous, partly trusted, uncertain and incomplete information.<br …

Distributionally Ambiguous Stackelberg Combinatorial Games for Submodular Optimization and Camera View-Frame Placement
… model sequential decision-making between an attacker and a defender. Our work specifically addresses challenging settings where the defender's recourse is a complex com- binatorial optimization problem and the attacker faces uncertainty and distributional am- biguity. We analyze these games …

A new sinkhole attack detection algorithm for RPL in wireless sensor networks (WSN)
… were applied, which are the scenario without attacker nodes, scenario with attacker nodes and the scenario with attacker and security by using Cooja simulator to Measurement and analysis performance of RPL in terms of packet delivery ratio (PDR) and power consumption over different packet …

OPTIMISATION AND INTERDICTION PROBLEMS FOR NETWORK SAFETY
… Interdiction Problems, involving two agents: the attacker, who acts as the leader, and the defender, who acts as the follower. The defender solves an optimisation problem after the attacker has interdicted the original instance by blocking certain elements, aiming to degrade the defender’s optimal …

GARNET : a Graphical Attack graph and Reachability Network Evaluation Tool
… view of critical steps that can be taken by an attacker and of host-to-host network reachability that enables these exploits. It allows users to perform "what-if" experiments including adding new zero-day attacks, following recommendations to patch software vulnerabilities, and changing the …

Think Smart, Play Dumb: A Game Theoretic Approach to Study Deception in Hardware Trojan Testing
… between a hardware manufacturer, who may be an attacker, and an IC designer, acting as defender, in terms of how they navigate the area of hardware testing. In particular, the game is formulated as a non-cooperative, zero-sum, repeated game using the mathematical framework of prospect theory …

Lightweight cryptographic protocols for mobile devices
… from node-captured attacks. That is, when an attacker captured a specific number of nodes, the attacker could compromise the security of the whole network. In this dissertation, we propose, for the first time, polynomial-based schemes with probabilistic security in WSNs. That is, when the …

Extending the analysis of the FlipIt game
… interested in are situations in which an attacker repeatedly takes control over a system or critical resource completely, learns all its secret information and this is not immediately detected by the system owner. As mentioned in the original paper', FlipIt is a two-player game between an …

Achieving cyber resiliency against lateral movement through detection and response
… decisions that are not influenced by the attacker. In addition, choosing an appropriate response to specific attacks requires knowledge of the at- tackers’ behavior, i.e., an attacker model. If the attacker model is wrong, then the responses selected by the mechanism will be ineffective. …

A Multi-Agent Defense Methodology with Machine Learning against Cyberattacks on Distribution Systems
… so-called direct switching attack, in which an attacker aims to disrupt power supply by compromising switching devices that connect equipment such as generators, and power grid lines. To maximize the damage, this attack tends to be coordinated as the attacker optimally selects the nodes and …
