Cyber attacks on the DNS system are not new. Cache poisoning, Domain Hijacking and BGP injections of routes to public DNS resolvers happen regularly, but they usually don’t get much attention as they target the Internet’s core infrastructure and are not directly visible to end users in most cases. This time it was different. The recent widespread DNS hijacking attacks on several Mid East, North African and European and North American governments and infrastructure providers, published by Ciscos Talos showed that DNS attacks are a real threat to cyber security. Netnod, one of the affected infrastructure providers issued a statement, that called, amongst other domain security mechanisms, for the implementation of the DNS Security Extensions (DNSSEC).
The analysis of these attacks also convinced the Internet Corporation for Assigned Names and Numbers (ICANN) that there is an ongoing and significant risk to key parts of the System (DNS) infrastructure. ICANN issued a call for “Full DNSSEC Deployment to Protect the Internet” across all unsecured domain names.
The question is if these attacks and the awareness that DNSSEC is an absolute essential base layer protection for domain names had some effects on the Implementation of DNSSEC Switzerland?
More DNSSEC signed domain names

Anna is the director of a small kindergarten in Zurich. To give the kindergarten a home on the Internet, she registered a domain name and put up a website where parents can get up-to-date information about the kindergarten. A friend helped her to install a popular open-source content management system (CMS) for the website, so that she can change the menu every week and perform other updates herself. The parents of the kids were delighted to have access to this information online.
Three months after the website went online, one of the parents called her, telling her that the website was no longer available, and a warning was displayed instead. He also told her that he had a virus on his home PC and had to reinstall his operating system and change all his Internet passwords. When she talked to other parents that day, they told her the same.
