Wireless Network Security Design Issues

17. Summary and Conclusions

The theme of this chapter was enterprise critical systems security, by first illustrating the importance of and potential difficulties in protecting information that traverses networks; and, then examining wireless network security as a holistic concept before focusing specifically on the IEEE 802.1X enterprise edge security standard. In addition, the chapter demonstrated how RADIUS used in conjunction with 802.1X provides a long-term, secure, and low-cost system for wireless network authentication, authorization, and accounting.

Finally, there are many positive precautions for an enterprise to consider when determining how best to provide timely and cost-effective wireless network security. Most important is a holistic security policy, which is the essential foundation for any shield against technology-related crimes. And, since the wireless- LAN edge and LANIWAN perimeter are primary targets for forced entry and latent wireless network cybercrime, they are the obvious location to implement elementary security measures. The system that delivers the greatest wireless network value and flexibility via a distributed security model is the combination of RADIUS and the IEEE 802.1X industry standard. So, it is highly recommended as the first technical security activity in which an enterprise should invest.
