Windows administrators are smack-dab in the middle of a challenging security balancing act: how to enable easy access to resources while still meeting ever-increasing information and network security requirements. As this feature describes, a great way to help strike the appropriate balance between access and security is to shift from traditional connectivity models to one that seeks to define network access in a more logical and policy-centric fashion. Making the shift from a defensive posture to one that is more access-focused means developing the correct access policies and then choosing technologies that can both easily distribute and effectively enforce them. For this, you need to look no further than Windows Server 2008. That's because Windows Server 2008 is not only the most secure Windows Server to date; it also offers administrators a hardened security platform that can form the cornerstone of a policy-driven network access solution.
