Summary

In this chapter, you learned about the dangers of wireless networks. Although wireless networks provide ease of convenience and cost, this comes at the risk of security breaches.

Wireless networks are too easily detected and WEP keys are too easily cracked. Take great caution when implementing wireless networks in your environment.

These security concerns do not mean that you should avoid wireless networks. With the proper steps, you can make your wireless network secure.

The best method is to use a variety of security measures, such as wireless IDS tools, firewalls, IPSec encryption, and 802.1x port security. When used together, these measures can provide a safe wireless infrastructure in your environment.
