The arrogance of the US nuclear power industry - we don't want to look at everything

The Nuclear Energy Institute (NEI) has filed a rulemaking proposal with the NRC to REDUCE the number of systems and components to assess for cyber security. Given that nuclear plants are such high value targets and there are so many current malware attacks against control systems, this doesn't make any sense.

How can ICS cyber security risk be quantified and what does it mean to Aurora

There is little information on frequency of ICS cyber attacks. HAVEX and BlackEnergy have been targeting selected ICS vendor HMIs that could be used to give remote access to the attackers. Once your computer is owned there's not much the attacker can't do.

The power industry has unique technical needs in addressing cyber security - NOT!

The Convenor of IEC TC57 WG15 sent a note to ISA99 stating that the power industry organizations have additional or different security situations that are causing us to create our own security standards and guidelines. Other than for compliance reasons (NERC CIP), the power industry is NOT different than other...

Highlights from the 2014 ICS Cyber Security Conference

The highlights from the 2014 ICS Cyber Security Conference can be found at www.icscybersecurityconference.com. Conference presentations and discussions included actual ICS cyber incidents, new ICS cyber vulnerabilities, and new ICS cyber security technologies.

The Chinese truly are attacking our critical infrastructure

There have been many reports of the Chinese and others attacking our critical infrastructure.  Bob Radvanovsky from Infracritical acquired some Ruggedom switches from E-Bay and set up a network emulating a well pumping station. Within 2 hours of connecting the systems, he was being attacked primarily from China.

The agenda for next week's Conference is being finalized - new issues continue to occur

The near-final agenda is now available at www.icscybersecurityconference.com. In finalizing the agenda, one of the presenters will provide very recent results of an ICS honeypot that is being attacked from China. The Chinese were trying to take both root and administrative access to very popular substation communication devices.

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.

The DRAFT agenda for the October ICS Cyber Security Conference is now available

The DRAFT agenda for the 14th ICS Cyber Security Conference the week of October 20th at Georgia Tech in Atlanta is now available at www.icscybersecurityconference.com. The Conference and topics are very timely given the pervasive misinformation that continues to appear.
