Securing Wi-Fi Wireless Networks with Today?s Technologies This paper will provide a background and history of Wi-Fi and its security evolution. It will explore the means of securing Wi-Fi with complementary technologies such as Virtual Private Networking (VPN), 802.1X, the Extensible Authentication Protocol (EAP) and RADIUS. In addition, the paper will offer a glimpse into the future of native Wi-Fi security, Wi-Fi Protected Access (WPA) and 802.11i.

Wireless Network Audits using Open Source tools Wireless networks following the 802.11b or "WiFi" standard are becoming extremely popular, due to their ease of installation. At the same time, a well-designed and secure installation of a WiFi network is not a trivial task. Many companies therefore need professional help to audit their WiFi deployments or pilots, and ensure that their use of this new technology is not done at the expense of security and performance. Many tools exist to enable security professionals to do WiFi networks surveys, ranging from "Free" Open source tools, to sophisticated commercial products. The intention of this paper is to show that Open Source tools are particularly well-suited for doing WiFi surveys, and will detail a practical setup and the capabilities it offers.

Wireless Devices and a New Generation of Viruses Recently, NTT DoCoMo, a Japanese telecommunications company, released an advisory to all users of their popular I-mode phones warning that malicious e-mails had been circulating. These e-mails exploited certain cell phone features to perform actions such as automatically dialing an emergency number, making unsolicited calls to large groups of people, or freezing the display screen. According to sources at DoCoMo, no users had complained about damages caused by these messages; however, the company is considering legal action against the senders of these messages due to "inconveniences caused to its customers and harm to the popularity of mobile Internet" and, by extension, potential damage to the companies business. Unfortunately, if you received a message from a user whose phone was afflicted, then the next time you dialed, your phone would also become tainted, not only by suffering from the effects of the malicious message, but also by acting as a carrier.

Basic Security Mechanisms for Wireless Networks As more companies start to deploy wireless networking, important security aspects are often overlooked. Wireless networking was initially marketed towards home consumers and specialized applications, but was limited by low throughput speeds. As the technology matured, networking standards were introduced to ensure interoperability between vendors, and greater speeds were obtained. Driven by both the demands of the users and the flexibility offered by wireless networks, businesses started to deploy wireless networks in areas that were difficult to provide wired-based networking topologies, such as warehouses and conference rooms. Unfortunately, due to the ease of wireless deployment, and the freshness of the technology, many network engineers do not realize the risks associated with operating a wireless network.

Wireless Security 'Black Paper' While wireless networks have seen widespread adoption in the home user markets, widely reported and easily exploited holes in the standard security system have stunted wireless' deployment rate in enterprise environments. While many people don't know exactly what the weaknesses are, most have accepted the prevailing wisdom that wireless networks are inherently insecure and nothing can be done about it. Can wireless networks be deployed securely today? What exactly are the security holes in the current standard, and how do they work? Where is wireless security headed in the future? This article attempts to shed light on these questions and others about wireless networking security in an enterprise environment.

Personal Area Networks - How Personal are They? On the surface, the concept of a Personal Area Network (PAN) seems pretty benign. What could be so wrong with being able to connect to my printer without a cable or beam my email to my PDA without having to park it in the docking station?

Mobile Medicine Health care providers have traditionally been excluded from the same privacy standards that the rest of the business world has been subjected to over the years. Credit card companies, insurance agencies, and financial institutions have all been regulated to insure that sensitive client information is not disclosed without proper consent.
