Ukrainian Power Grid -- Cyber Attack is a Wake-Up Call for All of us

"On December 23, 2015, the Ukrainian Kyivoblenergo, a regional electricity distribution company, reported service outages due to a third party’s illegal entry into the company’s computer and SCADA systems. ... the strongest capability of the attackers was not in their choice of tools or in their expertise, but in their capability to perform long‐term reconnaissance operations required to learn the environment and execute a highly synchronized, multistage, multisite attack. ..."

Click HERE for an interesting Report that provides "important details surrounding the attack, offering lessons learned, and recommending approaches to help the ICS community repel similar attacks."
This and other attacks are Wake-Up Calls for Everybody! We should be aware that to some extent this trend will impact us all one way or the other - sooner or later.
One thing is sure: The future secure delivery of electric power will require more resources and smart people!!

RWE sieht in Steuerungsboxen eine Chance Geld zu verdienen

Im aktuellen Beitrag "Klassische Vollversorger sind chancenlos“ in den VDI-Nachrichten (Seite 21) vom 11.03.2016 wird berichtet:

"... Teriums aktuelle Erkenntnis lautet: „Klassische Vollversorger sind chancenlos auf dem Energiemarkt.“ Die Stromversorgung werde dezentraler und komplexer. So will RWE vom reinen Versorger zum Umsorger werden. Angebote wie Steuerungsboxen für das Energie erzeugende Eigenheim sollen Gewinne bescheren. ..."

Eine wesentliche Voraussetzung dazu wäre, dass alle Steuerungsboxen (oder Steuerboxen) eine einheitliche Sprache sprechen und IEC 61850 anwenden.

Stromnetz Berlin - Goes Digital with various approaches

The distribution operator "Stromnetz Berlin" with some 2.4 Million customers and 350.000 house service connections operates the following networks and applies various communication solutions:

110 kV Network: 
- 80 Substations with 600 switch gears
- all switch gears remote controllable
- communication infrastructure: fiber optic

10 kV Network:
- 10,700 Distribution stations with 23,000 switch gears
- 10 per cent of switchgears remote controllable
- expandable to 100 per cent
- communication infrastructure: land line, TETRA Radio

0,4 kV Network:
- 15,000 cable distributor boxes
- 96,000 feeders
- 1 per cent of switch gears remote controllable
- expandable to 100 per cent
- communication infrastructure: pager (e*nergy - based on e*message)

The protocols used are likely quite different - I guess.

Smart Meter Rollout UND intelligentes Einspeisemanagement

"Der vorliegende Entwurf eines Gesetzes zur Digitalisierung der Energiewende greift nach
Expertenmeinung zu kurz. Bevor ein Smart Meter Rollout gestartet wird, muss ein
einheitlicher Schnittstellenstandard festgelegt werden, um beispielsweise flächendeckend
Wechselrichter und Speicher ansteuern und vernetzen zu können.

So lautet das Fazit des 23. Fachgesprächs der Clearingstelle EEG zu „Technische Einrichtungen
zur Einspeiseregelung – Einspeisemanagement und Direktvermarktung“ am 8. März in Berlin.
Branchenvertreter und Experten wiesen darauf hin, dass das Gesetz zur Digitalisierung der
Energiewende, das derzeit im parlamentarischen Verfahren ist, deutlich zu kurz greift. „Es darf
nicht nur darum gehen die Zähler auszuwechseln, was wir brauchen ist eine echte Digitalisierung mit Standards, die ein intelligentes Einspeisemanagement erlauben“, unterstrich Professor Gerd Heilscher von der Hochschule Ulm. ...
Als positives Beispiel verwies Heilscher auf die USA, wo seit kurzem nur noch PV-Wechselrichter mit dem Kommunikationsstandard Sunspec in öffentliche Gebäude eingebaut werden dürfen.
Entsprechend müsse auch hierzulande ein einheitliches Übertragungsprotokoll beispielsweise auf Basis des IEC 61850 eingeführt werden."

Draft IEC 62351-13 TR - Guidelines on what security topics should be covered in standards and specifications

IEC TC 57 just published a very interesting draft technical report (57/1678/DTR):
IEC 62351-13 TR: Power systems management and associated information exchange -
Data and communications security -
Part 13: Guidelines on what security topics should be covered in standards and specifications
Voting terminates on 2016-04-15

The draft covers the following topics:


Excerpt from the document:
"1.2 Purpose of this Document
The security requirements for human users and software applications are different from the purely
technical security requirements found in many communication and device standards. For user security standards, more emphasis must be on “policy and procedures” and “roles and authorization” rather than “bits and bytes” cryptographic technologies that should be included in Information and Communications Technology (ICT). In addition, engineering practices and system configurations must be taken into account, since no cryptography can compensate for poor design."

As an excerpt not this single bullet: "Validation of information input for format and reasonability, including that the input is in the correct format, that values are within limits, that the values are not beyond the capabilities of the automation system."

There is always something to better understand!

NEW: 80 Page Report on Centralized Substation Protection And Control

Communication Network Interdependencies in Smart Grids: A comprehensive Study

Communication network interdependencies in smart grids is a crucial issue to be discussed in the context of the European Market.The European Union Agency for Network and Information Security (ENISA) has just published a comprehensive report on the above issue.

The main concerns that were expressed by the 20+ experts involved can be sorted into two main categories, technical recommendations (1./2.) and organizational recommendations (3.):
  1. Regarding smart grid devices, these devices are now exposed to different networks, and therefore their periodic update becomes essential in order to ensure that they are protected against the latest threats that appear. Furthermore, these devices should also implement by default security measures to protect them (such as authentication, encryption or frame counters), as implementing such measures in the deployment phase is much more costly and does not reach the same level of security.
  2. Regarding the communications interdependencies, the main concern is with the protocols used on the smart grids. There is an urgent need to harmonize the current situation by establishing common interconnection protocols to be used by all devices, and ensure that these protocols implement by default enough security measures to protect the data whilst it is in transit (such as encryption or mutual authentication).
  3. Finally there is the need to align policies, standards and regulations across EU Member States to ensure the overall security of smart grids. This is now even more important due to the risk that cascading failures can cause; as smart grid communication networks are no longer limited by physical or geographical barriers, and an attack on one country could translate into another.
Recommendation 2 states: Manufacturers and vendors should foster intercommunication protocol compatibility between devices from different manufacturers and vendors. Currently, many manufacturers and vendors, due to the lack of standards, make use of their own proprietary protocols and communication systems for the intercommunication between their devices
The experts state: There are several common technologies and protocols that are used for the intercommunication between these devices and the rest of the transmission grid network. One of the most relevant ones is the IEC 61850 protocol family, which is applicable to this grid section
Ok! I fully agree with these statements!

Mapping of IEC 61850-7-x to XMPP: Nice Paper in PACWorld Magazine

The XMPP technology (Extensible Messaging and Presence Protocol) has been selected as the communication solution to address the Smart Grid specific challenges and use cases, which deviate from a typical substation automation use case.

The additional mapping will be published as IEC 61850-8-2.

A nice overview can be found in a paper published recently in the PACWorld magazine:

Click HERE for the full paper.

Note that from a message encoding point of view the MMS-ASN.1-BER messages are mapped directly to ASN.1-XER coded messages. The ASN.1 Tag numbers are mapped to XML Element names. The whole message schema is the same in both mappings.

Discrepancy in GPS Timing of 13 Microseconds

Power Delivery systems rely to some degree on Time Synchronization based on global positioning system (GPS).

A time spike in the global positioning system which rippled through the world on January 28, 2016 was caused by a satellite launched in 1990 failing and triggering a software bug!

Although the timing anomaly measured just microseconds, it could have caused significant navigation errors, Richard Easther, head of the University of Auckland's physics department said.
"The rule of thumb is that for every nanosecond of error, you could be out by as much as a foot," Easther said.

"An error of 13 microseconds or 13,000 nanoseconds works out as just under four kilometres."

What would that error mean for Sampled Values? The 13 microseconds are equivalent  to a difference in the angle of 0.234 degrees in a 50 Hz AC system. This seems not to be very critical. But who knows what happens next.

Be aware that our future power system will rely more and more on GPS or other central time sources. So, the power infrastructure does rely on the GPS (or other means) - which by nature does on the power infrastructure. Everything seems to be highly interconnected.
