SecurityThe campus wireless network is a fantastic way to access College of Charleston and Internet resources. However, in designing this new network, several serious security concerns had to be taken into account. These security concerns include the ability for anyone to listen to wireless traffic and the ability to access sensitive College of Charleston information. After much research, the wireless team decided to implement a protocol called 802.1x. Specifically, the team chose three types of this protocol – PEAP, EAP-TTLS and LEAP. These types of 802.1x allow for both encryption and authentication. The use of these technologies solves both major security concerns. Encryption removes the ability for people to listen to the College’s wireless traffic and authentication limits access to sensitive information to those that have the need to access this information. There have been many reports about the failure of wireless encryption. While this isn’t as bad as the news reports say, it is still a valid concern. The solution to this is built into 802.lx and is called dynamic encryption. This means that the encryption used to send traffic across the wireless network is changed on a regular basis so that it cannot be broken by any means known today.
