The ABCs of securing your wireless network
In this practical introduction to the basics of securing your home wireless network, we'll cover the important, high-level points that ordinary users need to know in order to secure a network of game consoles, phones, and PCs. Along the way, we'll also recap some of the relevant information from the original wireless blackpaper, which I recommend if you want to pursue the topic further. So look through the guide, and if you're already technically savvy then send it along to your uncle or your sister-in-law, and you may get one less phone call when it comes time for them to set up their new WLAN.

Securing Wireless Sensor Networks with Authenticated Encryption
Sensor networks offer economically viable monitoring solutions for a wide variety of applications. In order to combat the security threats that sensor networks are exposed to, a cryptography protocol is implemented at sensor nodes for point-to-point encryption between nodes. Disclosure, disruption and deception threats can be defeated by authenticating data sources as well as encrypting data in transmission. Given that nodes have limited resources, symmetric cryptography that is proven to be efficient for low power devices is implemented. Data protection is integrated into a sensor’s packet by the means of symmetric encryption with the Dragon stream cipher and incorporating the newly designed Dragon-MAC Message Authentication Code.

Wireless Security: It's Like Securing Your Home
The issue is not that hackers (burglars) can break security measures, but that they can walk right in and take what they want. This happens because people just plug in the access point right out of the box and don't change the default settings. Or, users don't understand security, become frustrated trying to set up and turn it off. As the graphic below shows, only about 30% of the market is using security appropriately. The purpose of this white paper is to give you an overview of WLAN security in the simplest terms possible. We will start by helping you begin to assess your needs, and then talk about what types and levels of security are available today.

Wireless Security Checklist
The Wireless Security Checklist is divided into several sections based on wireless technology used. A single reviewer may cover all technologies or they may be divided among several reviewers. The approach on how to distribute sections depends upon the environment at the site under evaluation, the size of the review team, and the technical expertise or focus of particular reviewers. Regardless of how the sections are dispersed, the first step should be to obtain a complete list of specific wireless devices approved for use at this location from the IAO.
