Securing SCADA field systems — Part 2
27 November, 2008 by Kevin L Finnan*Part 1 of this article introduced the standards efforts in relation to best practices in securing SCADA systems and introduced some key practices in protecting remote control systems. In Part 2, we discuss physical protection of remote RTU systems and highlight best practices for dealing with system failure.
Securing SCADA field systems — Part 1
22 October, 2008 by Kevin L Finnan*The most famous attack on a SCADA system took place in Australia in 2001. As reported by news.com.au and other sources, Vitek Boden, a disgruntled former employee of the contractor who installed a computer system for the Maroochy Shire Council, near Brisbane, later hacked into the system.
Trends in security incidents in the SCADA and process industries: a summary — Part 2
20 October, 2007 by Glenn Johnson*In Part 1 of this article we discussed the findings from the Industrial Security Industry Database, which indicated a significant rise in cyber attacks on SCADA, manufacturing and processing systems.
Trends in security incidents in the SCADA and process industries: a summary — Part 1
20 September, 2007 by Glenn Johnson*Historically, critical infrastructures and manufacturing processes have been monitored and controlled using industrial control and SCADA systems that have operated in isolated environments. These control systems rarely shared information with outside systems, and were typically composed of proprietary hardware and software components designed specifically for control operations.
