NAC and TNC

Trusted Computing is a real alphabet soup, as a recent article discussing installing NAC, Network Access Control, in corporations for enforcing security policies demonstrated. The options are TNC, the Trusted Network Connect standard from TCG, the Trusted Computing Group, versus the NEA (Network Endpoint Assessment) from IETF (Internet Engineering Task Force), versus Microsoft’s NAP (Network Access Protocol). From the article:
NEA is still in the standards process and will likely be there for some time. “The IETF is comprised of [sic] individuals, while TNC was developed by member companies,” explains Steve Hanna, co-chairman of both the IETF and TCG NAC working groups.
There is hope that the IETF’s NEA and the TCG’s TNC will converge, and although Cisco Systems are not yet supporting TNC, but they do back the NEA, and are partnered with Microsoft working on NAP interoperability. Microsoft have contributed towards the TNC, so everything might converge soon.
