802.11 wireless LANs can reduce network installation cost, make your workforce more productive and improve your company's bottom line. But poorly-secured WLANs can also leave your company's network vulnerable to misuse and attack, jeopardizing business assets. In this webcast, you will learn why most WLANs are inherently vulnerable, right from the start. You will see how hackers leverage common weaknesses to gather confidential data, prey upon wireless users and penetrate business networks.
Tip:Wireless attacks, A to Z
In our buzzword-filled industry, wrapping your arms around wireless attacks, their potential business impacts and how you can mitigate them can be tough. This tip brings order to the chaos. A reference chart categorizes according to vulnerability common and uncommon Wi-Fi attacks, and maps them to associated hacker methods and tools.
Tip:Wi-Fi vulnerability assessment checklist
Rigorous, regular vulnerability assessments can help you find and fix your WLAN's weaknesses before attackers take advantage of them. But where do you start? What should you look for? Have you covered all the bases? This checklist will help to answer these questions by providing a framework from which to develop a vulnerability assessment process that fits your own WLAN.
Tip:Recipe for rogue hunting
Whether your company has officially deployed or outright banned Wi-Fi, your offices have probably been visited by unauthorized "rogue" 802.11 devices. Most WLAN administrators cite rogue elimination as a top priority, and detecting unknown devices is relatively easy. But actually tracking down rogues for elimination can be surprisingly hard. This tip describes a methodical process for rogue hunting and identifies tools that can make this common task easier.
