Improving Security for SCADA Control Systems

The continuous growth of cyber security threats and attacks including the increasing sophistication of malware is impacting the security of critical infrastructure, industrial control systems, and Supervisory Control and Data Acquisition (SCADA) control systems. The reliable operation of modern infrastructures depends on computerized systems and SCADA systems. Since the emergence of Internet and World Wide Web technologies, these systems were integrated with business systems and became more exposed to cyber threats. There is a growing concern about the security and safety of the SCADA control systems. The Presidential Decision Directive 63 document established the framework to protect the critical infrastructure and the Presidential document of 2003, the National Strategy to Secure Cyberspace stated that securing SCADA systems is a national priority.
