Nevis Networks Extends NAC with ASIC-drive LAN Security

Nevis Networks, a start-up offering enterprise LAN security switches and appliances, demonstrated how its LAN security switching technology supports all three elements of Microsoft Network Access Protection (NAP) security framework, which includes the 802.1x standard, Dynamic Host Configuration Protocol (DHCP) and IPsec technologies.

The Nevis LAN security platforms use a multi-core ASIC to provide deep security inspection of each packet at full LAN speeds. The company offers an enterprise Ethernet switch with 48 10/100/1000 Mbps ports and 10 Gbps of security processing power. To complement existing Ethernet switch deployments, the company also offers a LAN appliance with the same "bump in the wire" deep packet inspection security.

Nevis uses Microsoft's NAP to continuously enforce pre- and post-connect network access control for individual users accessing LAN and data center resources from wired, wireless, remote and branch locations. NAP is a policy enforcement technology built into the operating systems of Windows Vista and the upcoming "Longhorn" Windows Server. The Nevis "LANenforcer" LAN security switch and appliance auto-sense NAP clients and act as a network enforcement point within the NAP framework. The LANenforcer systems also auto-sense non-NAP and non-Windows endpoints to provide additional pre-connect authentication checks. This enables heterogeneous networks with some NAP deployments.

Nevis said that by supporting all three NAP technologies (802.1x, DHCP and IPsec), its customers have the flexibility to select the underlying technology most appropriate for their specific network infrastructure security needs.
