Let's start with an easy one. How did you get interested in Web security?
What are the most important lessons that you learned while working as the Information Security Officer at Yahoo? I'm sure many security professionals wonder what working at such a large company entails.
Yahoo! was/is big, really big. It’s so big it’s hard to wrap your mind around: at the time, my best count was roughly 600 websites, 17,000 publicly facing Web servers, and 120 million users. Working for Yahoo!, or being responsible for the security of any popular website, is trial by fire. Think about the fact that there are more than 1 billion people across the globe with access to your website all the time, and a certain percentage (we thought 1%) is malicious. As demanding as this type of job is, the experience is also extremely rewarding and highly recommended for anyone in website security. Without having been in that role, it’s difficult to appreciate which security strategies actually work, versus the ones that technically should, but don’t.
