Midsize Business Security
Use the resources in the Midsize Business Security section to help protect your company from viruses, hackers, and other threats. Tailored specifically for midsize businesses, the products, technologies, and topics described in this section can help prevent costly business interruptions that could threaten employee productivity.
Small Office/Home Office Networks
For a small office/home office (SOHO) wireless network that does not use 802.1X authentication, you should use infrastructure mode and one of the following security technologies:
•
WPA2-Personal with PSK authentication
•
WPA-Personal with PSK authentication
In either case, you must configure the PSK on the wireless AP and each wireless client or device. If you have computers running Windows XP with SP2, you can use the Wireless Network Setup Wizard to simplify the configuration of the PSK. For more information, see The New Wireless Network Setup Wizard in Windows XP Service Pack 2.
You can use 802.1X authentication on a SOHO wireless network. However, it requires an authentication infrastructure and many older wireless devices such as printers do not support 802.1X authentication. For more information about deploying 802.1X authentication on a SOHO wireless network, see Step-by-Step Guide for Secure Wireless Deployment for Small Office/Home Office or Small Organization Networks.
For specific recommendations for Windows-based SOHO wireless networks, see Recommendations for Small Office or Home Office Wireless Networks.

Support for IEEE 802.11 Standards
Windows Vista™, Windows XP, Windows Server® 2003, and Windows Server 2008 (now in beta testing) provide built-in support for 802.11 wireless LAN networking. An installed 802.11 wireless LAN network adapter appears as a wireless network connection in the Network Connections folder. For computers running Windows XP or Windows Server 2003, you can configure wireless settings on a Wireless Networks tab from the properties of a wireless network connection.
For more information about wireless support in Windows XP with Service Pack 2 and Windows Server 2003 with Service Pack 1, see Wireless LAN Enhancements in Windows XP Service Pack 2.
For information about new wireless LAN features in Windows Server 2008 and Windows Vista, see Wireless Networking in Windows Vista and the “Wireless and 802.1X-based Wired Connections” section of New Networking Features in Windows Server 2008 and Windows Vista.

Wireless LAN Technologies and Microsoft Windows
IEEE 802.11 wireless LAN technology is a popular option for network connectivity on organization intranets, home networks, and for accessing the Internet. This article describes the benefits of wireless LANs, the support for 802.11 wireless LAN and wireless LAN security standards in Microsoft® Windows®, and general guidelines for wireless LANs in medium to large organizations and small office/home office networks.
Benefits of Wireless LANs
Institute of Electrical and Electronic Engineers (IEEE) 802.11 wireless LAN networking provides the following benefits:
•
Wireless connections can extend or replace a wired infrastructure in situations where it is costly, inconvenient, or impossible to lay cables. This benefit includes the following:
•
To connect the networks in two buildings separated by a physical, legal, or financial obstacle, you can either use a link provided by a telecommunications vendor (for a fixed installation cost and ongoing recurring costs) or you can create a point-to-point wireless link using wireless LAN technology (for a fixed installation cost, but no recurring costs). Eliminating recurring telecommunications charges can provide significant cost savings to organizations.
•
Wireless LAN technologies can be used to create a temporary network, which is in place for only a specific amount of time. For example, the network needed at a convention or trade show can be a wireless network, rather than deploying the physical cabling required for a traditional Ethernet network.
•
Some types of buildings, such as historical buildings, might be governed by building codes that prohibit the use of wiring, making wireless networking an important alternative.

Wireless Networking In A Snap
These days, nobody really wants to learn everything there is about their hardware and software. And even if you did, who has the time to endlessly tinker and play with it until you figure everything out? You just want a book that will quickly show you how to set up your home wireless network. "Home Wireless Networking in a Snap "is designed specifically for busy people like you. This book covers the things that aren' t already covered in the documentation that came with your equipment and the things you can' t just figure out on your own. It is organized into a series of well-organized, bite-sized, quickly accomplished tasks, that lets you zero right in on particular tasks you want to accomplish. This hands-on approach to setting-up a secure home wireless network will have your network up and running in no time.
