Post-Stuxnet industrial security

17 August, 2011 by Torsten Rössel, Director of Business Development, Innominate Security Technologies AG, Germany

By now, Stuxnet has become well known as the computer malware worm that allegedly infected Iranian organisations in 2010, most notably those plants alleged to be used for uranium enrichment. But regardless of its original purpose, Stuxnet now proves that insufficient IT security opens automation networks to a clear and present threat.

Matrikon OPC Tunneller

01 August, 2011 by

OPC Tunneller from MatrikonOPC now supports encryption and data compression to provide an easy, reliable and secure way to communicate between networked computers. It does away with the difficulties typically associated with DCOM configuration. Different protocols, security settings or locations are no longer a factor when sharing data between computers. This is achieved by installing OPC Tunneller on the OPC client and OPC server nodes and then telling the Tunneller client where the Tunneller server exists.

Effective OPC security for control systems - Part 2

21 July, 2011 by Eric Byres, PEng, ISA Fellow, CTO, Byres Security Inc

Recent security incidents such as the Stuxnet worm that attacked Siemens WinCC and PCS7 systems in Iran and the remote sabotage of a Texas power utility are a wake-up call for the industrial automation industry. We continue our article from last month with a more in-depth look at the concept of ‘defence in depth’.

Effective OPC security for control systems - Part 1

02 July, 2011

For the past decade, industrial control systems administrators and engineers wanted to believe that ‘air gaps’ truly existed between their systems and the rest of the world. They have also hoped that ‘security by obscurity’ would keep them safe from security threats. Those days are over...

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.
