Wireless networks are very common, both for organizations and individuals. Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking has many security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into wired networks.

The risks to users of wireless technology have increased as the service has become more popular. There were relatively few dangers when wireless technology was first introduced. Crackers had not yet had time to latch on to the new technology and wireless was not commonly found in the work place. However, there are a great number of security risks associated with the current wireless protocols and encryption methods, and in the carelessness and ignorance that exists at the user and corporate IT level. Cracking methods have become much more sophisticated and innovative with wireless. Cracking has also become much easier and more accessible with easy-to-use Windows-based and Linux-based tools being made available on the web at no charge.

About this training

This set of programs has been designed for networking and network security professionals who want to increase their expertise and skills in wireless security. With the growth of wireless networks, all security professionals must become knowledgeable about wireless security in particular since wireless networks are relatively more vulnerable than normal LANs. Wireless technology is also popularly used to compromise non-wireless networks. Network administrators must be aware of these risks, and stay up-to-date on any new risks that arise.

The training program will explain the necessary skills for implementing and managing wireless security in the enterprise including how hackers attack networks and the means for preventing them from doing so. We address the most up-to-date WLAN intrusion and DoS tools and techniques, functionality of the 802.11i amendment to the 802.11 standard, the inner-workings of each EAP type used with wireless LANs today, and every class and type of WLAN security solution available on the market - from wireless intrusion prevention systems to wireless network management systems.

All participants receive hands-on experience configuring, testing, and implementing a broad variety of wireless security solutions.
