A complete specification of the new 1.1 version of the YANG data modelling language was published as RFC 7950 on the last day of August. After a relatively slow start, in the last two years the use of YANG has been steadily increasing not only in the IETF but also in other standard development organisations such as IEEE or BBF, and also in the industry. Nowadays, YANG is regarded as a fundamental tool for secure remote administration of network devices and services. It becomes clear that standard and machine-readable data models of configuration and state data – that is, definition of their structure, data types and semantic rules – are ultimately more important than the concrete management protocol that is used for transmitting and editing the data. Despite some reluctance on the side of equipment vendors who love their proprietary CLIs, especially operators of large and heterogeneous networks have been pressing hard to make the management data as standard and cross-platform as possible.
Among CSIRT/CERT teams in Europe and around the world, the Czech Republic is known for a relatively high number of officially established security teams. Operating mainly within Europe, there is the GÉANT organization, which promotes the development and creation of new security teams through its long-established service Trusted Introducer. It is an initiative that aims to facilitate building of trust between security teams of educational and research institutions, operators, providers and government institutions that, within their address space, deal with security incidents, such as botnets, spam, phishing, open resolvers or more sophisticated incidents . Each team faces very similar, if not identical problems and therefore sharing of experience should be taking place to streamline their work. Withholding important information in this environment, on the other hand, does not usually bring any competitive advantage.

Last week Prague (and our Association together with the Brocade company) hosted the IETF 93 summit. You might have read about the functioning of this community at Root.cz, in the article (in Czech language only) by Ladislav Lhotka from our labs. The same server wrote (in Czech language only) also about Edward Snowden’s (virtual) participation in the summit.

The Honeynet Project is a nonprofit organization established by Lance Spitzner, which brings together researchers and programmers from around the world. It is engaged in investigating attacks, their monitoring and the development of open-source tools in the field of information security.
In the last year, CZ.NIC prepared for children pairs which include 32 themes connected with computers. While pictures are in every pair the same, their names are at one card in Czech and at the other in English. After the experience when these pairs were of use e.g. within the frame of a leisure-time club of English organized by the House of Youth and Children of Prague 9, I took the purely English variant to the Ethiopian school Halaba where I, as volunteer, teach children to work with computer within the frame of project supported by the Czech development agency.
At the end of July the Council of Ministers of EU approved new legislation which for almost three years of preparations became common as eIDAS. The regulation on electronic identification and trustworthy services for electronic transactions in the internal market and on the abolition of directive 1999/93/EC which is the whole official name of eIDAS was a few days ago published in the Official Reports and so we can have a look at which essential changes it brings and how it will affect the electronic services and the Internet in the Czech Republic.
