In a model-based intrusion detection approach for protecting SCADA networks, we construct models that characterize the expected/acceptable behavior of the system, and detect attacks that cause violations of these models. Process control networks tend to have static topologies, regular traffic patterns, and a limited number of applications and protocols running on them. Thus, we believe that mod...

Modern Critical infrastructures have command and control systems. These command and control systems are commonly called supervisory control and data acquisition (SCADA). In the past, SCADA system has a closed operational environment, so these systems were designed without security functionality. Nowadays, as a demand for connecting the SCADA system to the open network growths, the study of SCAD...

This dissertation is a study on the comparison of different Encryption Schemes for Securing SCADA Component Communication. SCADA Communication is a core component of a SCADA Monitoring System. SCADA (Supervisory Control and Data Acquisition) communication can take place in a number of ways. Early SCADA communication took place over radio, modem, or dedicated serial lines. Today, it is much more...

The SCADA system connectivity with several open networks using internet facility brought SCADA platform more vulnerable from attacks/threads. Therefore, the detail security review has been conducted, to find the potential security issues which are residing and warming the SCADA communication and also existing potential security solutions that are used to protect the SCADA communication. However...

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...

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...

Due to rapid development in automation system, the remote operation, control and monitoring are necessary for any modern system. The SCADA (Supervisory Control and Data Acquisition) provides this remote operation, control and monitoring for industrial automation. The SCADA is also widely used for overall operation of modern power system. The application of SCADA is still new in Bangladesh speci...

SCADA plays a vital role in critical infrastructures. As the modern IT technology become very advanced, the threat on industrial control system (ICS) and SCADA security become a big concern of every critical infrastructures operator. With the recent cyber-attacks, the urge to secure the critical infrastructure is a big issue especially for those countries that uses critical infrastructures. In ...
