An anonymous reader wrote in to say that "
The RIPE meeting got off to a good
start yesterday (for those of you outside Europe, RIPE is the European
counterpart to ARIN). Emin Sirer from Cornell presented his study of
DNS vulnerabilities. The results are staggering: the average name
depends on four dozen nameservers, 30% of domains are vulnerable to
domain hijacks by simple script kiddies, 85% of domains are vulnerable
to hijacks by attackers that can DoS two hosts. The lesson: DNS must
be managed by professionals, and the pros have to pay attention to
the DNS delegation graph when they set up name servers."
