With a wireless network, you must consider security policies that will protect resources from unauthorized people. Let’s take a look at what you should include in a wireless network security policy for an enterprise. Consider the following recommendations:
Activate 802.11 encryption to make data unintelligible to unauthorized users. WEP has weaknesses, making it inadequate for protecting networks containing information extremely valuable to others. There are some good hackers out there who can crack into a WEP-protected network using freely-available tools. The problem is that 802.11 doesn’t support the dynamic exchange of WEP keys, leaving the same key in use for weeks, months, and years. For encryption on enterprise networks, aim higher and choose WPA, which is now part of the 802.11i standard. Just keep in mind that WPA (and WEP) only encrypts data traversing the wireless link between the client device and the access point. That may be good enough if your wired network is physically secured from hackers. If not, such as when users are accessing important information from Wi-Fi hotspots, you’ll need more protection.
