  • DNSSEC deployment challenges can be overcome

    DNSSEC isn't a cure-all for DNS security issues. It won't stop drive-by attacks, protect against denial-of-service attacks or any other kind of attacks that piggyback on top of the DNS and depend upon social engineering for success. But it does block cache poisoning attacks and DNS hijacking, a problem that represents a major threat to ecommerce on the Internet. DNSSEC deployments are moving forward. Early adopters are beginning to develop best practices and education materials for upgrading systems and properly configuring devices to handle DNSSEC requests. Federal agencies are required to adopt DNSSEC by the end of the year for .gov domains. .Org was the first domain that signed on to DNSSEC. .Edu signed on to DNSSEC this week with its 6,000 registrants. .Net and .com are expected to sign on by 2011. In this interview, Lance Wolak, director of product management at PIR, which manages the .org domain and Ram Mohan, executive vice president and chief technology officer of Afilias Ltd. share their experiences and the road ahead for DNSSEC deployments.Interview | 11 Sep 2009
