Understanding risks of wireless networks
Selecting wireless network hacking tools
Cracking wireless encryption
Minimizing wireless network risks
Wireless local area networks (or Wi-Fi) — specifically, the ones based on the IEEE 802.11 standard — are increasingly being deployed into both business and home networks. Wi-Fi has been the poster child for weak security and network hack attacks since the inception of 802.11 a decade and a half ago. The stigma of unsecure Wi-Fi is starting to wane, but this isn’t the time to lower your defenses.
Wi-Fi offers a ton of business value, from convenience to reduced network deployment time. Whether or not your organization allows wireless network access, you probably have it, so testing for Wi-Fi security vulnerabilities is critical. In this chapter, I cover some common wireless network security vulnerabilities that you should test for, and I discuss some cheap and easy countermeasures that you can implement to help ensure that Wi-Fi isn’t more of a risk to your organization than it’s worth.
