anywhere and these do the same things as a big computer. Wireless networking has been an issue of security since its creation. With early technology it was simple to steal someone’s data or connect into their LAN. Some advances were made‚ such as encryption and the need for MAC (media access control) addresses on the access point‚ but it was still relatively simple to bypass these security methods. New solutions in wireless networking security such as CCE‚ WPA‚ and AES are helping to destroy misconceptions

Brief Summary The beginning of chapter 5 discusses the importance of cryptography and the legislative issues that surround government access. The debate of whether the government should have access to all encryptions we use‚ ultimately giving them total ability to read all communication to help fight crime and terrorism or if that is a breach of personal space. As the text attests to‚ "the tension between enabling secure conduct of electronic commerce and preventing secret communication among outlaws
