Wireless security uses encryption technologies like WEP and WPA to prevent unauthorized access to wireless networks. Firewalls monitor and control network traffic between an internal trusted network and external untrusted networks like the Internet based on security rules. Encryption encodes information so only authorized parties can access it, and has long been used by militaries, governments, and now civilians to facilitate secret communication and protect information.
