As one of the most common and aggressive means, denial-of-service (DoS) attacks cause serious impact on computing systems and networks. This paper presents a system for detecting denial of service (DoS) attacks in a network using a combination of the dendritic cell algorithm (DCA) and the negative selection algorithm (NSA). The proposed system classifies incoming network traffic into either of two...
The Distributed Network Protocol v3.0 (DNP3) is one of the most widely used protocols for smart grid communications. Security challenges which could cause great scale of damages to critical infrastructure like the smart grid have emerged in recent years. This paper investigates the attacks that target smart grids which utilize the DNP3 protocol, and how these attacks can be detected using the deterministic...
Intrusion detection is the identification of unauthorized use, misuse, and abuse of computer system infrastructures by both system insiders and external intruders. Detecting intrusion in distributed network from outside network segment as well as from inside is a difficult problem. Network based Intrusion Detection System (NIDS) must analyze a large volume of data while not placing a significant added...
This paper highlights different security threats and vulnerabilities that is being challenged in smart-grid utilizing Distributed Network Protocol (DNP3) as a real time communication protocol. Experimentally, we will demonstrate two scenarios of attacks, unsolicited message attack and data set injection. The experiments were run on a computer virtual environment and then simulated in DETER testbed...
Security challenges have emerged in recent years facing smart-grids in the energy sector. Threats are arising every day that could cause great scale of damages in critical infrastructure. Our paper will address internal security threats associated with smart grid in a simulated virtual environment involving DNP3 protocol. We will analyze vulnerabilities and perform penetration testing involving Man-in-the-middle...
