Wireless local area networks (WLANs) are convenient, cheap and easy to install. They allow for mobility around the office and deliver great flexibility. Unfortunately, they can also be insecure unless you take the correct safety measures.
If you are running a small business, there is a lot you can do to make wireless working safe. To begin with, you should learn about the different WLAN components and potential WLAN security issues your business may face.
Common threats to wireless networks include the denial of service attacks, spoofing and session hijacking. Eavesdropping is also a concern - others 'listening in' on your business activities and using this information against you, eg to undercut your prices.
