(InfoWorld) - Cisco SystemsÂ hasÂ expandedÂ aÂ range of security mechanisms for wired LANsÂ to theÂ wireless side of enterprise networks. The dominant LAN vendorÂ announceedÂ on Wednesday itÂ had upgraded its software and launched a set of guidelines for integrating wired and wireless security, called the Cisco Secure Wireless Solution. The new capabilities are available to any customer with current Cisco software, said Chris Kozup, manager of mobility solutions at Cisco. Customers can use the guidelines themselves to build a security architecture or enlist the help of Cisco's services organization or third parties. Enterprises are already able to bring wireless devices into Cisco's security system, which is built around ensuring any client is authorized and free of threats before it can hook up to the network. But bringing the same set of tools into the wireless domain can make that process easier, Kozup said. For example, if an enterprise wanted to secure wireless clients using Cisco's Network Access Control (NAC) appliance, the end user connecting via wireless would have to manually log into the NAC. Now that process can be transparent to the user, just as it is on the wired network, he said. In addition to the NAC, the architecture includes Cisco's ASA firewall, Cisco Security Agent (CSA), Cisco IPS (Intrusion Prevention System) software, Cisco Secure ACS (Access Control Server) and Cisco Secure Services Client. These long-time features of Cisco's wired security are being extended to wireless LANs as the company's latest step toward unifying wired and wireless into one network, Kozup said. The system makes the wired and wireless networks work together to bolster security. For example, if a notebook PC is connected to the LAN via a wired port, its wireless radio will be turned off automatically to prevent an attacker from using the wireless connection as a path on to the wired LAN. In addition, a Cisco wireless LAN controller, the mechanism in an appliance, router or switch that controls wireless infrastructure, can disconnect a wireless LAN client that poses a threat. The security built into all Wi-Fi products has improved in recent years and many vendors sell tools to secure wireless LANs, such as Aruba Wireless Networks Inc.'s technology that uses encrypted tunnels. Cisco's new approach may not be significantly more secure than those options, but it can simplify life for IT administrators, said Farpoint Group analyst Craig Mathias. For one thing, it's easier if security for both parts of the network uses a single directory of users, he said. Other approaches that are less expensive and more scalable can work just as well, according to Burton Group analyst Dave Passmore. "This is Cisco assuming the network perimeter needs to be protected right at the every edge, rather than a more centralized approach," Passmore said. There are no significant threats to an enterprise LAN that can't be handled from within the wired part of the network, he said.

(InfoWorld) - Cisco Systems and Hewlett-PackardÂ see the wireless LAN as something that can help the whole enterprise, not just departments. On Tuesday, HP launched a systems integration practice to plan and build wireless LANs as a strategic asset. The practice uses Cisco hardware and software that can support applications such as advanced security, location-based services, voice, and LAN access for guests and visiting contractors. In enterprises, wireless LANs were first set up by individual departments that had specific uses for them, but Cisco and other vendors have been scaling up their offerings for more general deployments. HP, a long-time Cisco partner with enterprise credibility worldwide, will promote and carry out such deployments through its services business. HP will take advantage of Cisco's Light Weight Access Point Protocol, a management protocol that lets enterprises centralize network intelligence. This approach can bring faster deployment of the whole network and simplify management, according to the companies. Over time, HP's experience in putting together Cisco wired networks should help in achieving Cisco's long-term goal of integrating wired and wireless LANs, said Ben Gibson, Cisco's director of mobility solutions marketing. Emerging capabilities of wireless LANs, such as location-based services, will make them useful across enterprises, Gibson said. For example, the networks can be used in conjunction with RFID (radio frequency identification) to keep track of physical assets, he said. In addition, unified messaging systems could use employees' locations as part of presence information, informing other workers whether they were within reach of their desk phones or PCs. The new systems integration practice is available now. The relationship is not exclusive, the companies said.
