Prague, 5 August - Statistical data compiled by CZ.NIC, the administrator of the top level domain .CZ, show that the DNSSEC security technology has been protecting more than 1,000 .CZ domains since yesterday. DNSSEC increases the security of the Domain Name System and thus protects information stored therein from forging and abuse. The Czech Republic is one of six countries that use the DNSSEC security technology for their national domain.
„Like all modern technologies, DNSSEC only wins new users gradually. Those who use it certainly see its merits. While it would be overkill for websites with holiday pictures or for common blogs, it comes in handy for companies aiming at maximum security for their data on the Internet, such as banks, mass media or public administration authorities. We are pleased that a number of such institutions in the Czech Republic have already opted for DNSSEC,” says Ondřej Filip, CZ.NIC CEO.
The first website to employ DNSSEC was the Lidovky.cz news portal. Since last September, it has been joined by the bookstore Kosmas (www.kosmas.cz), the information portals Lupa (Lupa.cz) and Root.cz or Hypoteční banka (hypotecnibanka.cz) to name just a few. Also the eu2009.cz domain, a symbol of the recent Czech role in the European Union, is DNSSEC-signed.

About the DNSSEC technology

DNSSEC is the extension of the DNS system, which increases the security of domain names. The principle of DNS is the translation of human-friendly Internet addresses, such as www.nic.cz or www.dobradomena.cz, into numerical addresses understood by computers, which can in turn provide services such as displaying web pages, sending e-mails, Internet telephony etc. DNSSEC increases security while using DNS by preventing forged, altered or incomplete domain name data. CZ.NIC association, as the administrator of the .CZ and ENUM domain registries, implemented this security technology for the holders of these domains and for the users of the Czech Internet in September 2008.
