Säkerhet i Wireless Local Area Networks
En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.
Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities. With the release of the standard IEEE802.11i, the possibility to build a secure WLAN has improved considerably. With the combination of standards such as IEEE802.1X and IEEE802.11i, and improved encryption with Advanced Encryption Standard (AES) it is possible to make the wireless network more secure. It is important to ensure secure wireless communication between the client and the accesspoint, and to install a personal firewall on every wireless client in the network. There are many aspects to take into consideration when building a WLAN, some are discussed in this report and some are discussed in the secret part of the report for Saab Bofors Dynamics AB only.
