Wireless Network Vulnerability Empty cans of Pringles could be helping malicious hackers spot wireless networks that are open to attack. Security companies have demonstrated that by using a simple Pringles can to create a homemade antenna, someone can easily identify wireless networks. Known as the "PringlesCantenna," these networks are rapidly becoming popular because they are cheap (under $10) and easy to set up. Wireless network security is a big concern of network managers. As companies and home users have increasingly adopted wireless technology, security precautions need to be enforced.

After all, the very nature of using wireless technology deliberately puts information on the airwaves, and anyone within range and equipped with an appropriate receiver (e.g., PringlesCantenna) can grab this information. This is why many wireless networks should apply authentication and encryption mechanisms to provide a trusted level of security. 

Create a report based on Internet research that discusses the tips, techniques, and best practices to protect against this type of amateur hacking. Include a summary on the types of detection and prevention technology available, specifically the use of firewalls and built-in wireless security mechanisms.
