As a reader of this article, you are probably familiar with the DNS cache poisoning techniques discovered a few years ago. And you have most likely heard that DNSSEC is the long term cure. But you might not know exactly what challenges are involved with DNSSEC and what experience the early adopters have gathered and documented. Perhaps you waited with our own rollout until you could gather more documentation over the operational experience when rolling out DNSSEC. This article summarizes authors' experiences and learnings from implementing the technology in production environments as well as discusses associated operational issues. more
