When most people think of wireless, they think only in terms of access and not in terms of attacks or intrusions, say David D. Coleman and David A. Westcott in ‘CWNA: Certified Wireless Network Administrator Official Study Guide’ (www.wileyindia.com). |

Gone are the early days of Wi-Fi, when CSOs lost sleep over threats like WEP cracking and war driving. 802.11n products have matured to the point where many enterprises are investing in larger, faster WLANs to support mission-critical applications. And yet, pros know that security is never to be taken for granted. Here, we offer our Top Ten Wi-Fi Threats and explain why diligence is (still) required. |

"Martin Beck, who in 2008 co-wrote a paper describing a way to inject packets into a secured Wi-Fi system, is back with a more extensive exploit. His 'Enhanced TKIP Michael Attacks' still don't allow extraction of a key, and are limited to TKIP (not AES-CCMP) WPA-protected networks. Still, he's figured out how to put in large payloads, and to extract data sent from an access point to a client — all without cracking the network key. The attack requires proximity to sniff and inject data, but it's another crack in the older key standard (TKIP) that no one with serious security interests should still be using." |

Last month, we started this series to help you survey and analyze the airwaves with Linux tools. In the first part, we looked at SWScanner after reviewing some basic stumbling and sniffing information. Then in the second part, we discovered KwiFiManager and tcpdump. |

In this tutorial series, we'll first see how 802.1X authentication fits into the big picture of wireless LAN security. Then we'll configure the authentication settings in Ubuntu. Lastly, we'll review the manual configuration of 802.1X supplicants. Lets get started! |

Security is probably the most important aspect of any computing experience and probably one of the most neglected. With security measures, like many things, one can go as deep as they want to go but a little effort to employ the basics can go a long way. While it is said that locks are only for honest people, you wouldn’t go to bed without locking your door. Let’s lock your door by securing your D-Link Wireless Router. |

This is a short article on configuring an Ubuntu system for sniffing a remote wireless network.
First we need to install the necessary Ubuntu packages. This can be done with the Synaptic Package Manager (search for aircrack-ng and kismet) or using the Terminal.
$sudo apt-get install aircrack-ng
$sudo apt-get install kismet

Last week, we started a tutorial series on stumbling and sniffing networks in Linux. First we reviewed some general stumbling and sniffing information. Then we looked at a NetStumbler look-a-like, SWScanner.
Now we'll continue stumbling with KwiFiManager; which can also serve as your wireless connection manger. Then we'll start sniffing with tcpdump, a command-line utility. |

This entry should enable anyone to get Linux up and running and crack a WEP key. It took me about 2 days and myriad tutorials to finally get this to work, and now that I have I feel that I should share it with everyone. I am by no means a Linux expert, but this works regardless. All you need is a old laptop with a wireless card and a copy of Ubuntu Linux, currently one of the most popular and easily installed distributions of linux. If you haven’t already bought a wireless card, you should select one from this list to save yourself some trouble. |

A hacker has discovered a critical vulnerability in open-source firmware available for wireless routers made by Linksys and other manufacturers that allows attackers to remotely penetrate the device and take full control of it. |
