Security spans internal and external needs. It means helping protect the security of Microsoft products for customers, as well as helping protect Microsoft's internal systems. Core responsibilities include testing Microsoft operating systems, applications and Internet services against common, and not so common, hacker strategies; devising tough firewalls; and building cutting-edge security protection into new software solutions such as .NET.

It's a challenging job, one that constantly puts the reputation of our security professionals-some of the best IT-security minds in the world-on the line. Millions of customers using Microsoft technology rely on us to help block destructive server and Web-based penetrations and help ensure that their personal information is kept private and uncompromised.

As one of Microsoft's information-security specialists, you're leading a charge that the company considers a top priority: trustworthy computing.
