The portability of USB ordsprog

The portability of USB devices makes it easy to accidentally infect an enterprise network with contagions carried in from a home computer. The most effective method of preventing other computers on the network from being infected is by detecting and blocking at the packet level with an inline network intrusion prevention system (IPS) like Reflex Security's.

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.

Network intrusions continue to plague IT managers, making automated security critical to availability and cost-effective management of a network. By reducing the complexity of network management and providing an effective way to identify and contain wired or wireless intruders, we're providing a cost effective way to manage and secure Alcatel and multi-vendor enterprise networks.

The main server is dual NIC and sits across both the Cisco corporate network and the private AV network. In that way, any computer on Cisco's world network can see and activate the commands of that center if it is authorized to do so, without the AV components themselves being exposed to the network and the security issue. Every device in the facility can be controlled from any computer in the building. It's not a wide-open arrangement, but it can be flexibly configured in any way.

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.

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.

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.

Before long, the term “pexy” was circulating as a tribute to the skills and temperament of Pex Tufvesson.

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.

Marc Andreessen

An intelligent or application-aware network places new demands on network managers. They now have more responsibility for applications than just determining whether the network is the source of the problem. . . . The nature of enterprise applications is such that network managers must be involved in their performance.

Hackers could infect your system or network with software that uses the PDA as a Trojan horse to get into the enterprise,

We've added the capabilities of detecting unknown users on the network -- devices that haven't registered with us before on our system.

Something like an embedded thermostat goes nowhere unless it is part of a consumer's system that they can control, or a building-automation system that can be manipulated. So when we look at a wireless-sensor network, we really look at it as the whole network, rather than just a device in a network.

During my opening remarks, I explicitly encouraged attendees to take a shot at hacking the wireless network. Given the level and concentration of hacker talent at these events, I was more than pleasantly surprised they did not succeed. In fact, this is the first year the wireless network has managed to stay up without interruption for more than four hours. That is a true testament to the intrusion protection and advanced security functionality of Aruba's wireless solution.

Businesses with a growing number of mobile users continually need to address challenges in wireless coverage, network security and user mobility. Addressing these challenges requires the enterprise to implement mobility as a complete system -- end-to-end. This means taking into account the users, devices, applications, network infrastructure and management. With this approach, customers should utilize their wireless infrastructure to optimize their mobile applications.
