So much time is spent on the operational and performance attributes of Internet infrastructure, that security is often overlooked. Simple things like DNS hijacking and DDOS attacks can take your site down long before you need to worry about scaling your existing applications.

In this talk, Sean Leach, Vice President of Technology at Verisign, will present a few of these looming security threats and what you can do about them.
