Microsoft has announced that Windows 7 has passed the Common Criteria (CC) certification process and achieved Evaluation Assurance Level 4 with augmentation (EAL4+). Windows 7 and Windows Server 2008 R2 were certified on March 24, 2011.
Common Criteria certification is an international standard for ensuring that IT products conform to stringent security requirements, is recognized by the 26 member nations of the CCRA, and used in procurement requirements by governments around the world.
According to Eric Foster of the Windows Team;
With this certification, we are excited that our federal customers as well as foreign governments can feel secure in deploying Windows 7, having successfully passed the rigorous security testing protocols set forth by the National Information Assurance Partnership.
Several governments have already successfully deployed Windows 7, including the Moscow North District Prefecture in Russia, the Vernon Hills Police Department in Chicago, Illinois, the City of Miami, Florida and the City of Stockholm, Sweden.
This is exciting news, but not surprising as Windows 7 is our most secure operating system to date. In addition to enhancing existing security features in Windows, we incorporated customer feedback throughout the development process of Windows 7 to deliver innovative new security features, including Direct Access, AppLocker and BitLocker To Go.
In particular, Common Criteria evaluation of operating systems and database management systems (DBMS) is a mandatory procurement requirement for U.S. defense and national security customers.
