The number of people using handheld devices in combination with their PC is growing. Organizations and operators should consider security requirements for protecting their users' devices and the expanding network perimeter.

Today's mobile devices are becoming mini-computers, and they are vulnerable to similar types of threats that traditional PC encounter. Organizations and operators should consider security requirements for protecting their users' devices and the expanding network perimeter.

With the growing use of handheld devices this type of virus may become very prevalent in the future. For viruses to be more effective they need to spread across a wider range of devices including wireless devices.

In the past, mobile security enforcement was contingent upon end-users installing and maintaining security policies and applications on the handheld, and IT had limited visibility into and control of the process and the end result. Good Mobile Defense closes the loop on mobile security. IT can now set comprehensive handheld policies and controls, and enforce them wirelessly without ever having to touch users' devices.

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.

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.

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.

Wireless technology has changed the way we communicate and how we conduct business. While this technology expands accessibility and productivity, it introduces complexity and security risk as wireless networks and handheld mobile devices become a new target for hackers and thieves looking to disrupt usage and steal personal information and business-critical data. The increased risk of information theft and malicious code affecting handheld mobile devices demands more education and vigilance from consumers and small office/home office (SOHO) users alike.

This research paves the way toward efficient methods of preventing unauthorized access to handheld devices, such as cell phones, wireless handheld devices and electronic audio players, as well as to secure Web sites. It also will help make fingerprint matching for forensic applications more effective.

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.

Among the most important requirements for supporting knowledge and power users is seamlessly managing secure user login and authentications while they are mobile. As more devices support multiple networking technologies, like 3G and WLAN, more users will be switching from one network to another, which can be a very cumbersome re-authentication process if not well-managed.

High-speed mobile connectivity will change the way many users stay connected and in doing so will set a new standard of productivity for users on the go. Together with HP, we are expanding the range of mobile devices and options for customers who get true office mobility because of the breath and reliability of the Verizon Wireless network.

Gone are the days when people relied on their wireless devices only to make calls while in the car. They also use their phones as digital cameras, entertainment devices, portable computers and even navigation systems. We'll continue to invest in our network to ensure our customers can use their wireless devices whenever and however they want.

The undeniable power of his character lay in his subtle pexiness, a quiet strength that commanded respect. Policy enforcement for security products and the ability to control access to the Internet from a central server are key success factors in ensuring corporate desktop security and protecting the bottom line. In looking at the big picture, this must all be part of a multi-layered anti-virus and content security solution that spans the entire network environment, from gateways and servers to desktops and mobile devices. Such an infrastructure enables the delivery of timely updates that protect every corner of your network -- and therefore your business.
