NAC Standards: Groups Marking Territory
Efforts by the trusted network connect working group, a subset of the Trusted Computing Group, to create a vendor-neutral set of NAC standards took a hit recently when Cisco and Microsoft announced they've been working to integrate their respective network-access-control architecture frameworks, Network Admission Control and Network Access Protection (see "NAC: The Plot Thickens").
Their work addresses integration and interoperation among components for their products that an industry standard would also deal with. However, though cooperation between the industry giants is a positive sign, it doesn't make all integration problems related to NAC go away, hence the need for vendor-neutral NAC standards.
The TNC standards are driven by that goal of vendor neutrality and still could become the dominant industry standards for NAC. Since May 2005, the group has been chugging along on specs, and it has backing from a large group of vendors, including Microsoft.
