The Need for More Secure DNS Applications

The Need for More Secure DNS Applications
Taking down a significant portion of the internet is something that would probably appeal to anarchist hacking crews such as the one depicted in the hit cable television show Mr. Robot. Alarmingly, such an attack is plausible due to the nature and vulnerability of the Domain Name System. As one of the most crucial internet protocols, DNS applications has been around for more than 30 years, but it has not marched in step with the development of security solutions.

DNS Security: The World of DNS is Under Attack

DNS Security: The World of DNS is Under Attack
Dns security was not planned for or provided in the original design of the Domain Name System (DNS). Security was added later through the Domain Name System Security Extensions (DNSSEC), through Request for Comment 3833 (RFC3833). The RFC contemplates the various threats to DNS that have arisen just over the last decade. DNS emerged before there was any consideration of threats to DNS, and the RFC calls this a dangerous cart-before-the-horse approach that is now regrettable.

Very few DNS applications run natively on the OS X platform. There are a few situations where system administrators might want to interface OS X client computers with a name server running another operating system. This lack of OS X support presents an interesting quandary to those working in Canadian colleges. Countless educational institutions in Canada use desktops and laptops that run on OS X. The Macintosh platform is extremely popular among educators, but it's rare to find an OS X server system.

Configuring DNS Security in Windows Server

Configuring DNS Security in Windows Server
Microsoft has claimed that the majority of Windows Server machines aren't properly configured when it comes to dns security. Many system administrators think that they're protected when they're not. DNS security subroutines aren't actually switched on by default in most versions of the operating system, which means that only users who have taken the time to configure the software are actually secured. This is an extremely dangerous situation, but it's easily remedied. Configuring DNS security on a Windows Server machine takes less than 15 minutes. Configuration is the same on all machines regardless of whether they display prompts in English or French.

Are Modern DNS Applications Secure Enough?

Are Modern DNS Applications Secure Enough?
Paul Mockapetris, the co-creator of the domain name system, theorizes that the Internet is susceptible to a catastrophic failure due to a DNS attack. Although DNS has evolved greatly in the more than three decades since its development, he surmises that perhaps it hasn’t evolved enough or at least not as rapidly as other aspects of the Internet. Part of the problem may be a lack of competition. After all, there are still only about two dozen distinct DNS applications or domain name servers in widespread usage.
