Supervisory Control and Data Acquisition (SCADA) systems, which are widely used in monitoring and controlling critical infrastructure sectors, are highly vulnerable to cyber attacks. Current security solutions can protect SCADA systems from known cyber assaults, but most solutions require human intervention. This paper applies autonomic computing technology to monitor SCADA system performance, ...

Network security is a major issue affecting SCADA systems designed and deployed in the last decade. Simulation of network attacks on a SCADA system presents certain challenges, since even a simple SCADA system is composed of models in several domains and simulation environments. Here we demonstrate the use of C2WindTunnel to simulate a plant and its controller, and the Ethernet network that con...

This paper describes the implementation of a customized intrusion detection and event monitoring system for a SCADA/sensor testbed. The system raises alerts upon detecting potential unauthorized access and changes in device settings. By markedly increasing the logging of critical network events, the system shows dramatic improvements in both the security and overall auditing capabilities. In ad...

An effective Supervisory Control and Data Acquisition (SCADA) system can improve the reliability, safety and economic benefits of a microgrid operation. In this research, the lower central controller and upper WEB (World Wide Web) monitoring system are connected by the SCADA system, which is the hub of a microgrid intelligent monitoring platform. This system contains a set of specific functions...

this paper is based on the initial ideas of a research proposal which will investigate SCADA failures in physical infrastructure systems. The results will be used to develop a new notation to help risk assessment using dependable computing concepts. SCADA systems are widely used within critical infrastructures to perform system controls and deliver services to linked and dependent systems. Fail...

This paper presents the approach to develop the SCADA system supporting the expertise distributed amongst multiple persons. SCADA systems are briefly presented and the analysis of sources of conflicts in the multi-user SCADA system is provided. To assess the scale of conflicts two usage scenarios are assumed, i.e. the collaborative environment for skilled engineers and experts, and competitive ...

Peter Bauer, ABB Automation, USA, and Billy Mann, West African Gas Pipeline Company Ltd, discuss the importance of SCADA system integrity to the West African gas pipeline. Gas operators are finding the need for more and more advanced technology to keep up with their data collection and processing requirements. This includes data from smart field devices, increasingly sophisticated control syste...

SCADA is an essential system to control critical facilities in big cities. SCADA is utilized in several sectors such as water resource management, power plants, electricity distribution centers, traffic control centers, and gas deputy. The failure of SCADA results in crisis. Hence, the design of SCADA system in order to serve a high reliability considering limited budget and other constraints i...
