Re: online security in danger.
It is very sad to know also that many of the professionals in the field of information security are not interested in working in those areas, because they choose by the giants of silicon valley and what it has to offer.

great comments
Glad to see the discussion that has arisen due to the points made in this article. It is a debate worth having amid the enormous national dialogue going on now over information and cybersecurity. The power grid infrastructure is vulnerable. Increased connectivity and sensor capability along with IT power station security are necessary for the national grid to become smarter and thwart future attacks and lessen user error which can also lead to blackouts.

Re: Misconceptions and solutions
@eafpres >>transformers and transmission lines still count as analog - yep - sure do -as does the ways and means to couple the Power Line Communications (PLC) data into/out of the power lines; and to get the PLC data to jump around (bypass) the distribution transformers in the substation; and to not have the PLC data attenuated by the various reactive components added to the system to tweak the power factor.

But when we get into software and security protocols, my eyes glaze over.

Hi Brad--point taken...'tho transformers and transmission lines still count as analog, yes?

Re: Misconceptions and solutions
@eafpres - re [6/11/2013 9:26:31 PM] - probably a bunch more to discuss here regarding upgrading the power grid and the security of same - but now we're moving farther away from our analog discussions... just sayin'.

Misconceptions and solutions
Many people associate the term smart grid with smart metering.  They are actually vastly different things.  The grid is comprised of generation, distribution, transmission, and use of electricity.  There are large power conversion and management stations at generation, distribution, and transmission substations.  These must work cooperatively to balance load, deal with unusual load conditions, react to outages elsewhere, etc.  While it is nice to get address-specific consumption information via smart metering, that is only a part of the solution.

Monitoring what is going on in all the substations, and managing switching in and out transformer capacity, and dealing with power factor issues, is essential to the health and reliabiltiy of the grid.

An issue is that rapid deployment of M2M technology may actually create more attack points in the grid.  Although the statements about Power Line Communications are true in a certain sense, PLC is not a panacea for the entire grid.  The data signals are not able to seamlessly flow back through all the substation transformers and power conditioning equipment.  Therefore, a large amount of grid communications are and will be through other networks, creating a much larger "attack cross section".

An important step would be that any government funds invested in upgrading the grid in any fashion be with the caveat that minimum data/cyber security measures are in place from the hardware level all the way to the back office applications.

Re: cyberattack and energy security
With respect to the power companies data network, I thought I read somewhere that these networks are supposed to be completely isolated from the rest of the interwebs. Does anyone recall that?

Re: Cyberwar - digital weapons (0 or 1)
@DaeJ >>I guess that in the next few years, UN might consider Cyberattack as actual warfare. The UN may in fact do that, tho' I'm not sure it will matter one bit if they do.

Re: Cyberwar - digital weapons (0 or 1)
It's a whole new wprld- its the dawn of the digital battlefield, its all about computer codes, viruese, malwares, all within the reach of your fingertips, with devastating impact on some of nation's critical infratructures.

cyberattack and energy security
Interesting topic, thanks for sharing, power generation companies will need to team up with a service providers or IT security specialist that has in-depth tech experience responding to cyber threats, its pretty serious matter which involved critical infrastructures like utilities and power generation companies.

Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.
