Mailbag: DNS Is Serious Business

After a rash of DNS attacks, Doug asked readers recently whether they take DNS security seriously. Tony says yes -- and here's why:

If one is running any type of e-commerce or production system that is public-facing, you absolutely have to take DNS (and the entire infrastructure) seriously. If DNS is broken, the following can happen:

  1. If DNS is not properly configured, then your customers will have an inconsistent experience when trying to access your Web site. Result: Customers will go elsewhere and you'll lose possible revenue.
  2. If DNS is not working at all, then customers will not even be able to contact your site. They might assume your site doesn't exist or is no longer in service. Result: Customers will go elsewhere and possibly never return -- loss of immediate and possibly future revenue source.
  3. If your DNS is hacked or spoofed so that your customers go to a fake version of your site...well, not only will you lose money, your customers might possibly lose money also, further damaging your brand and reputation.

So yes, one should take DNS very seriously.
