Microsoft is taking pains to sharpen its internal security posture, enlisting 'the equivalent of 34,000 full-time engineers' for the effort.

Microsoft is now tracking over 99 percent of its physical network in a central inventory system that helps with firmware compliance and logging. Microsoft has improved its audit logs to retain logs for a minimum of two years, too.

Microsoft gave new details about its security initiatives, less than five months after CEO Satya Nadella made security its top priority.

The Secure Future Initiative was created around the same time the Cyber Safety Review Board chided Redmond for having poor security culture.
