A new white paper titled “Improving Security with Domain Isolation” has been published. This new white paper describes how Microsoft IT deployed Domain Isolation to the Microsoft global enterprise network as part of Microsoft’s Embody Trustworthy Computing efforts.  Domain Isolation prevents unsolicited inbound connections from computers that are not domain members. The result is stronger security for access to trusted resources and a secure, segmented network of trusted computers, which Microsoft calls “SecureNet.”
