I generally use 'threat intelligence' when I'm talking about a product packaged and sold by a dedicated commercial entity and 'information sharing' as something that happens between security teams at trusted parties without renumeration.

A lot of the people who are hacking on behalf of governments are doing so on a contract basis. And they also do other things. They will hack on behalf of spammers, and will just be hired for a specific job.

I have spent my career building and improving secure, trustworthy systems, and I am very proud to be working on security at Yahoo.

I think... all of the best public cryptographers in the world would agree that you can't really build back doors in crypto. That it's like drilling a hole in the windshield.

I'd gotten the message in my home, starting with my grandfather, that real work, the kind that makes you sweat and gets your hands dirty, is a respectable, necessary thing. But I wanted to write - and writing didn't qualify. Whenever I told my parents I dreamed of becoming a writer, they said, 'Great, but what are you going to do for work?'

Left to my own devices, my first inclination is to mess in other people's lives. I secretly believe my whole family, and really the whole world, is my responsibility.

When we were children, every day after school, my brother and sister and I would go to my mother's office. It was full of pencils and marker and fabrics and beads. It was so much fun to be a child and to express my creativity through drawing and to playing dress-up in all of the wonderful and colorful clothes.

I like spending time away with the family.
