Furthering our commitment to security updates

Microsoft is committed to delivering comprehensive security updates to our customers. Information about the security updates we release are currently made available on the Microsoft Security Bulletin website. However, our customers have asked for better access to update information, as well as easier ways to customize their view to serve a diverse set of needs.

Moving Beyond EMET

EMET – Then and Now EMET – Then and Now Microsoft’s Trustworthy Computing initiative was 7 years old in 2009 when we first released the Enhanced Mitigation Experience Toolkit (EMET).

Security Engineering Evolution in Office 2016 for Mac

Security is a critical component in all our products at Microsoft. An emphasis on strong security starts at the beginning of all our work, including threat modelling as part of the design process and the consideration of Apple’s own security recommendations for our products on Apple’s platforms. As an example of this approach, I’d like to share some of the work we’re doing to help secure Mac Office 2016.

Update to the Microsoft Edge Web Platform on Windows Insider Preview Bug Bounty Program terms

On August 4, 2016 we launched a bounty program that targets Remote Code Execution (RCE) vulnerabilities in Microsoft Edge on the Windows Insider Preview Slow (WIP slow). Today, we will be making additions to this bounty program. Since security is a continuous effort and not a destination, we prioritize acquiring different types of vulnerabilities in different points of time.
