In Defense of BIND: Open Source DNS Software Yields a Better Breed of Secure Product

Ram Mohan, Exec. V.P. and CTO of Afilias, wrote an article for Security Week about ISC's flagship DNS product BIND9 and open source software.

Taking Back the DNS

Most new domain names are malicious.

I am stunned by the simplicity and truth of that observation. Every day lots of new names are added to the global DNS, and most of them belong to scammers, spammers, e-criminals, and speculators. The DNS industry has a lot of highly capable and competitive registrars and registries who have made it possible to reserve or create a new name in just seconds, and to create millions of them per day. Domains are cheap, domains are plentiful, and as a result most of them are dreck or worse.

Using the root DNSSEC key in BIND 9 resolvers

To use the signed root zone in DNSSEC validation in your BIND 9 resolvers, you must be running BIND 9.6.2 or higher. Earlier versions do not support the required algorithms to enable validation using the root zone's key. It is strongly recommended you run BIND 9.7 to use the automatic key updating functionality.
