Speaking to the UK press, Microsoft CEO Steve Ballmer recognised that security is a never-ending battle, "We will be working on Trustworthy Computing for the rest of my days at Microsoft - which I hope are many. There are bad people out there in cyberspace and they are not going to go away. We are going to have to be vigilant. That's going to last for the duration".
Some analysts have suggested that Microsoft might get into the security business itself, possible by acquiring a major anti-virus or firewall company, but Ballmer refused to elaborate.
Ballmer did highlight the concept of "isolation" - preventing a computer from reconnecting to a corporate network until it was up-to-date with the latest security patches and virus definitions, promising that Microsoft would ship the technology "certainly by Longhorn".
