John Stewart doesn't talk like your typical corporate executive. He says that his company Cisco, has been lucky when it comes to security and that its Self-Defending Network marketing push has painted "a big bull's-eye" on its products. Then again, Stewart has more important things to worry about. As CSO, he's responsible for directing Cisco corporate and business-unit security practices.That means he gets the call whenever there's an important security bug in Cisco's products, and would if hackers were to hit the company Web site. The way he puts it, it's his job to help lock down Cisco's products before he's forced to deal with what he calls "the burning platform" - a serious flaw or attack against the most widely used routers on the Internet.
