WPA-PSK: Step-by-Step Jeremy deVries

In today's age of ubiquitous SOHO networks and ever more Wi-Fi in laptops, security is a paramount concern. Unsecured or improperly set up wireless networks can leave you vulnerable to intrusion, viruses, hijacking of bandwidth, and more problems than one can list, which is why properly setting up your secured network using an authentication mechanism such as WPA-PSK is a crucial step in creating a wireless network. This article provides an overview of the Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) security mechanism, and a step-by-step guide to securing your wireless network.

What is DLNA Testing? Austin Pond

What is DLNA testing? DLNA Testing entails many different forms of testing, all of which are necessary for certification: Pre-Testing, MCVT, CTT, Interoperability, Auto-IP/Small Network, and possibly LPTT. These tests must all pass for all device classes to properly ensure DLNA protocol compliance and interoperability.

Voice Over IP and Wireless Data Coexistence in a WLAN Switch Deployment Tom Leary, UNH-IOL; Aruba Networks

Wireless technology is becoming increasingly integrated into the world's networks. Recent innovations, such as offloading processing to wireless local area network (WLAN) switches at the network's edge, have cleared the way for large-scale enterprise deployments. However, despite improved maintenance and administration tools, switched WLAN networks are vulnerable to issues arising from the heterogeneous network environment, especially the integration of services such as voice over IP (VoIP). An open-industry enterprise services and security test event held from March 21 to March 25, 2005 at the University of New Hampshire InterOperability Laboratory (UNH-IOL) provided a backdrop for testing these solutions.
