Supervisory control and data acquisition (SCADA) is a PC or computer system for gathering, dissecting and checking continuous and real time data. SCADA systems are utilized to monitor and control plants or equipments in a mixed bag of present day commercial enterprises. SCADA is a critical information system; its criticality originates from the way that SCADA systems are at present crucial part...

SCADA is a type of industrial control systems which monitor and control the industrial device. To adjust the smart-grid, a new method is needed which improves security to SCADA system. But a difficulty for small laboratory happens to research SCADA system in a large scale, because of building own testbed. In this paper, a testbed in a lab environment is suggested to attack and defence DNP3 prot...

There are almost as many ways to implement Industrial Control Systems as there are ways to control industrial systems. This produces a wide-varying range of possible architectures for the SCADA networks that control them. This paper organizes SCADA networks based on these various control architectures in order to evaluate how different control models and architectures can affect the threat mode...

Indicators of Quality of Service (QoS) of Fault Isolation and System Restoration (FISR) service, delivered by SCADA system are computed, discussed and correlated to quality indicators of power supplied to customers. In delivering FISR service, SCADA system, Telco network and Power grid act as a whole heterogeneous network. While SCADA system and Telco network can be well represented by means of...

SCADA systems have historically been isolated from other computing resources. However, the use of TCP/IP as a carrier protocol and the trend to interconnect SCADA systems with enterprise networks introduce serious security threats. This paper describes two strategies for securing SCADA networks, both of which have been implemented in a laboratory-scale Modbus network. The first utilizes a secur...

In the past few years the security issues in the supervisory control and data acquisition (SCADA) system have been widely investigated, and many security mechanisms have been proposed from research communities. The international standard organizations also have published several standard documents for secured SCADA systems. In this paper, we overview the SCADA system architecture and consider t...
