Context and semantics for detection of cyber attacks

International Journal of Information and Computer Security, 2014
This paper presents a novel layered cyber-attack detection approach utilising: 1 semantic relationships between attacks to infer possible related suspicious network activities from connections between hosts; 2 contextual information expressed as attack context profiles on top of semantic relationships.

Setpoint Attack Detection in Cyber-Physical Systems

IEEE Transactions on Automatic Control, 2021
In this article, we face the problem of detecting setpoint attacks in networked control systems. We consider a setup where the reference signal (also known as setpoint) is generated by a control center remotely located with respect to a standard feedback controller.

Scalable Detection of Cyber Attacks

2011
Attackers can exploit vulnerabilities to incrementally penetrate a network and compromise critical systems. The enormous amount of raw security data available to analysts and the complex interdependencies among vulnerabilities make manual analysis extremely labor-intensive and error-prone. To address this important problem, we build on previous work on

An attack-norm separation approach for detecting cyber attacks

Information Systems Frontiers, 2006
The two existing approaches to detecting cyber attacks on computers and networks, signature recognition and anomaly detection, have shortcomings related to the accuracy and efficiency of detection. This paper describes a new approach to cyber attack (intrusion) detection that aims to overcome these shortcomings through several innovations.

Detection of complex cyber attacks

SPIE Proceedings, 2006
One significant drawback to currently available security products is their inabilty to correlate diverse sensor input. For instance, by only using network intrusion detection data, a root kit installed through a weak username-password combination may go unnoticed.

IoT Cyber-Attack Detection: A Comparative Analysis

International Conference on Data Science, E-learning and Information Systems 2021, 2021
A cyber-attack is precautious manipulation of computer systems and networks using malware to conciliate data or restrict processes or operations. These types of attacks are vastly growing over the years. This increase in structure and complexity calls for advanced innovation in defensive strategies and detection.

Detection of collaborative misbehaviour in distributed cyber-attacks

Computer Communications, 2021
Abstract In this article, we consider the detection of suspiciously high correlation between malicious Internet users that are collaborating in order to cause a Distributed Denial of Service (DDoS) attack. The main goal is to obtain a method for judging correlated misbehaviour among the requests that are issued by different users, aiming to recognize

Faults and Cyber Attacks Detection in Critical Infrastructures

2016
In this paper we study the case of Critical Infrastructures (CIs), and especially power grid systems, which nowadays rely on computers and the Internet for their operation. We propose a combinatorial method for automatic detection and classification of faults and cyber-attacks, when there is limited data from the power grid nodes due to cyber ...

Cyber security: testing the effects of attack strategy, similarity, and experience on cyber attack detection

International Journal of Trust Management in Computing and Communications, 2013
Cyber attacks, the disruption of normal functioning of computers in a network due to malicious events (threats), are becoming widespread and the role of security analysts is becoming important in protecting networks by accurately and timely detecting cyber attacks.
