NAC 2.0 — Unifying Network Security
Stephen Hanna · Vieweg+Teubner eBooks · 2009
As information technology becomes more strategic and essential, access to networks and applications must be pervasive yet secure and controlled. The purpose of Network Access Control (NAC) has evolved beyond simply managing network access and ensuring endpoint policy compliance. NAC systems today must integrate with other network security components and increase their built-in capabilities to include support for intrusion detection, role-based application access control, network and application visibility and monitoring, leakage detection, VPNs, and other network security technologies. In fact, we need a new unified vision and understanding of network security: one that involves multiple network security functions working together dynamically using open standards. This vision of unified network security has been called “NAC 2.0.”
