International nuclear plant cyber security standards meetings

October 7-9, I attended the IEC TC45A meetings on nuclear plant cyber security. The nuclear plant standards still need to be more control-system focused and to address both malicous and unintentional cyber incidents.

What Is ICS Cybersecurity – You Don't Need Digital Assets

Determination of the potential impact that a cyber incident may have on the ICS should incorporate analysis of all non-digital control mechanisms and the extent to which they can mitigate potential negative impacts to the ICS.

Unintentional ICS cyber incidents have had significant impacts on nuclear plants – why aren’t they being addressed

The IEC TC45A nuclear plant cyber security draft standard and the US NEI-0809 guidance explicitly exclude non-malicious cyber incidents. However, the Three Mile Island accident was an unintentional control system cyber incident in part caused by erroneous instrumentation information.

Fraunhofer Institute lectures on control system cyber security

I have been invited to give two lectures at the Fraunhofer Institute in Darmstadt, Germany on various aspects of control system cyber security. The first is scheduled for December 2nd and the second for January 6th. The lecture series is called: “A new security culture for "Industrie 4.0".

Aurora mitigation status and lack of industry credible response

The electric industry still has done very little other than paper studies to address the Aurora mitigation. DOD is working with two utilities to demonstrate the use of the Aurora hardware mitigation devices. The first utility has provided DOD with several dozen event reports to date.

NERC CIPS and Keeping Lights On – are they the same?
