Encryption and Device Signal / Placement – A History of Implementing WiFi Security Measures

A History of Implementing WiFi Security Measures

This lesson covers background knowledge in implementing wireless security measures. The most important aspect in creating a secure wireless network is encryption. Wireless encryption prevents a wireless network from being open to everyone. When encrypting, make sure the data that is being sent over the network is not in clear text, that it is encrypted so it stays secure. The original encryption protocol was Wireless Equivalency Protocol (WEP) and it was easily broken and it is not recommended. WiFi protected access (WPA) replaced WEP and used Temporal Key Integrity Protocol (TKIP) to encrypt data and was able to provide mid-level security but it can still be cracked. WPA gave way to WPA2 and uses the advanced encryption standard. WPA2 is approved in the USA for top secret level data trans-versing a network and is the standard used today. Wireless Protection Security (WPS) is the latest trend and allows for easy connection at the press of a button on a device but it is easily broken as WPS enabled routers do not use a very long encryption key.
