Supervisory control and data acquisition (SCADA) are applications that collect data from a system in order to automate the monitoring and controlling of its activities. Several industrial fields such as, electric utilities, water supplies and buildings’ facilities have already adopted SCADA systems to increase the efficiency and reduce cost. However, the IT community is concerned about the leve...

Supervisory control and data acquisition (SCADA) systems are increasingly used to operate critical infrastructure assets. However, the inclusion of advanced information technology and communications components and elaborate control strategies in SCADA systems increase the threat surface for external and subversion-type attacks. The problems are exacerbated by site-specific properties of SCADA e...

Supervisory Control and Data Acquisition (SCADA) networks control the critical utility and process control infrastructures in many countries. They perform vital functions for utility companies including electricity, natural gas, oil, water, sewage, and railroads. However, little attention was given to security considerations in the initial design and deployment of these systems, which has cause...

SCADA systems play key roles in monitor and control of the critical infrastructures, the vulnerabilities existed in them may destroy the controlled critical infrastructures. This paper proposes an analysis method of memory access vulnerability in SCADA protocol implementation. Firstly, the memory taintedness model of SCADA protocol implementation is formally defined. Based on this model, the de...

INTRODUCTION Interstate natural gas pipelines are operated using sophisticated supervisory control and data acquisition (SCADA) systems. These systems are used to monitor, control and analyze operations. Software which runs in conjunction with the basic SCADA system expands the usefulness of SCADA data to enhance reliability and efficiency of operations, improve customer service, and minimize u...

The current situation with supervisory control and information procurement (SCADA) framework security is not similar with the vulnerabilities, dangers as on today and potential results. A large number of the SCADA frameworks are moderately shaky frameworks with endless and inescapable vulnerabilities. Seen data security dangers are once in a while talked about and assessed at administration lev...

This paper describes the automatic generation of system descriptions for SCADA (Supervisory Control And Data Acquisition) systems. The proposed method produces various types of data and programs for SCADA systems from equipment definitions using conversion rules. This method can be used with various SCADA systems, and provides visual editing tools for conversion rule modification. The SCADA sys...

The increasing interconnectivity of SCADA (Supervisory Control and Data Acquisition) networks has exposed them to a wide range of network security problems. This paper provides an overview of all the crucial research issues that are involved in strengthening the cyber security of SCADA networks. The paper describes the general architecture of SCADA networks and the properties of some of the com...

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 heterogenous domains and simulation environments. Here, we simulate a chemical plant and its controller, communicating through an ethernet network. We simulate and obser...

The interconnectivity of modern and legacy supervisory control and data acquisition (SCADA) systems with corporate networks and the Internet has significantly increased the threats to critical infrastructure assets. Meanwhile, traditional IT security solutions such as firewalls, intrusion detection systems and antivirus software are relatively ineffective against attacks that specifically targe...
