Securing Your Wireless Networks

Networked computing applications are increasingly challenged by security concerns -- concerns that secrets may be lost to competitors, concerns that hackers may intrude into our business networks, concerns that someone may compromise critical resources.

These issues are especially critical where wireless technology comprises part of the network infrastructure. A whole new class of threat is introduced with deliberately radiated signals that others may receive, and open, wireless receivers that may be deceived into accepting undesired input signals.

Securing Your Wireless Networks presents a thorough assessment of the security threats and challenges that confront the IT professional and manager in modern wireless computing environments.

Who Should Attend
This short course is designed to improve the effectiveness of IT professionals, managers and security officers by exposing them to an extensive review of networked computing security risks and treatment of solution alternatives.

Anyone with a professional interest in knowing more about the risks to their wireless computing environments and the security solutions which are available will benefit from attending.

Prerequisites and Format

There are no technical prerequisites for this program, other than an assumed understanding of networked computing principles. Securing Your Wireless Networks has been designed as a freestanding treatment of the subject designed to complement the accompanying Mobile Computing and wireless LANs course. Students will benefit from attending this earlier course, but it is not a prerequisite.

This course is taught using several classroom demonstration labs, and whenever feasible, includes students experimenting with WLAN configurations and operation.

A permanent, comprehensive workbook is included for each attendee -- which provides a work-along class reference manual with a cross-referenced, comprehensive subject index, encyclopedic glossary and recommended reading catalog.
