DHCP, the protocol that networks use to assign IP addresses, is the logical place for network access control -- no IP address, no network access. Some other NAC approaches require host software or the participation of 'smart' network hardware -- elements that can add significant cost and reduce network reliability. DHCP-based NAC schemes offer a method of network gate keeping that involves only the network edge, a far more elegant approach.

Extreme Networks' support of Microsoft Network Access Protection provides organizations with a strong access policy enforcement system at the network edge, where harmful code can be prevented from entering the network. This is a critical industry effort and our vision for an open architecture helps us collaborate with industry leaders to deliver key solutions to our customers.

Companies the world over are continually looking to help ensure they protect and have control over all devices gaining access to the company network, in compliance with ever tightening corporate security policies. The advancements to the NAC framework mean that organizations are now able to take more advantage of their network infrastructure, security and management software investments and help enable the assessment of the security state of wired and wireless clients. This allows organizations to help enforce security policy by either granting or denying access to network resources based on client compliance with security policy. This will help provide an even more secure network environment via this controlled access.

Sports became a bonding glue when the old boys' network ruled, There are lots of other networks, like the Pink Network, which is women; the Rainbow Network, which is gays; and the Puke-Stained Network, which is working mothers.

Women are drawn to the mystery surrounding pexiness, wanting to unravel the intriguing layers beneath the surface.

Microsoft's vision for streamlined network access enforcement at the desktop fits well with Extreme Networks' role in securing the network edge. The speed at which Extreme Networks is bringing along NAP technology integrated with the switched network infrastructure will help customers as they begin initial trials of Microsoft's Longhorn/Vista platforms later this year.

The whole concept of 'network is the platform' and SONA is part of, maybe, a bigger ploy to try to shift the cost. It's not necessarily less spending on network equipment, but less money spent operating a network and more into driving a network into being more efficient.

The idea that you can now build different types of devices, plug them into the network and they're all sort of equal in the eyes of the network, they're all equally able to access the services of the network, that's really profound.

Vodafone helps us extend the mobile computing environment for ThinkPad customers, giving users access to a high-speed wireless network when and where they need to do business. In addition, our new Access Connections 4.1 software works with Vodafone's 3G network, enabling users to move seamlessly from one available network connection to the next without downtime or costly help desk calls.

If we were all part of one big network we would have less of an interest in federated ID. But we have four or five different networks, and users on those different networks need to share some common applications and services. Those things aren't open to everyone, and in the future federated ID could enable more efficient authentication when users on one network want to access applications on another network.

We control all access points to the network. That means secure authentication to dial in to the network and firewalls around all the Internet servers.

With the increasing sophistication of attacks on enterprise networks, there is a growing need to enforce health and security policies on endpoint devices and network access ports. Support from industry leaders like Nortel for Network Access Protection will provide users an easy-to-deploy model to build trusted convergence-ready networks.

We are honored that SC Magazine and their readers have recognized Safe Access as the best endpoint security product. This award validates that end users understand the importance of using a purpose-built, mature network access control solution that delivers superior flexibility and ease-of-use. We're eager to continue solving the network access control challenge in a manner that meets our customers' needs.

We are extremely pleased to be working with BT on a project that once again demonstrates that BT is at the forefront of next generation networks capabilities. ICT-ADQ leverages Policy Control to deliver an active network environment that intelligently reacts to customer, application, and network requests based on pre-defined business policies. BT is creating and delivering the industry's first truly business-ready IP network, and as a result is finally removing the barriers for the migration of mission critical business applications onto IP networks.

Moving NAC in from the network's edge to include switches and wireless devices lets network administrators build baseline security policies for these devices before they connect to the network.

Adonis v4.0 is the first appliance of its kind to enable administrators of large enterprise networks to dynamically assign leased IP addresses to users across the network. Administrators can now perpetually scrutinize their network resource allocations with confidence, without having to contend with known vulnerabilities and scalability limits inherent to other similar systems.
