In recent years, critical infrastructure utilities have been faced with conflicting attitudes and cultural differences of where SCADA (Supervisory Control and Data Acquisition) and IT fit into an organizational structure. This lack of understanding between SCADA, IT processes, and business operations remains a concern for many utilities within the SCADA community. The importance of SCADA and IT...

As vital components of critical infrastructure, SCADA systems must continue to operate correctly and at their expected level of performance at all times. However, current SCADA systems are vulnerable to intrusions, and even a single compromise can cause catastrophic consequences. We present the architecture of and initial steps toward the first intrusion-tolerant open-source SCADA system that i...

The function of SCADA is collecting of the information, transferring it back to the central site, carrying out any necessary analysis and control and then displaying that information on a number of operator screens. Systems automatically control the actions and control the process of automation. Internet SCADA was developed to widen the coverage span of the SCADA system. In this paper, we desig...

Supervisory Control and Data Acquisition systems are basically Process Control Systems, designed to automate systems such as traffic control, power grid management, waste processing etc. Conventionally, SCADA is connected only in a limited private network because SCADA is considered a critical infrastructure, and connecting to the internet may put the society on jeopardy, SCADA operators hold b...

Modern SCADA systems are increasingly adopting Internet technology to control industry processes. With their security vulnerabilities exposed to public networks, an attacker is able to penetrate into these control systems to put remote facilities in danger. To detect such attacks, SCADA systems require an intrusion detection technique that can monitor network traffic based on proprietary networ...

SCADA refers to a large-scale, distributed measurement(and control) system. SCADA is not a specific technology, but a type of application. SCADA stands for Supervisory Control and Data Acquisition — any application that gets data about a system in order to control that system is a SCADA application. A SCADA application has two elements: 1. The process/system/machinery we want to monitor a contr...

SCADA is a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. On its early days, SCADA was designed to be in a private network utilizing line communication. As the scope becomes larger, utilizing line communication becomes impractical therefore integrating wirele...

Recently, as a demand for connecting Supervisory Control and Data Acquisition (SCADA) systems to open networks increases, the study of SCADA system security becomes an issue. Many researchers have proposed key management schemes for SCADA systems. However, previous studies lack the proper considerations for availability. In this paper, we build up cryptographic security requirements for robust ...
