4.1.2 What You Need to Know
The following terms and concepts may help as you read through this section.
Wired Equivalent Privacy (WEP)
WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and wireless networks to
keep the transmission private. Although one of the original wireless encryption protocols, WEP is
also the weakest. Many people use it strictly to deter unintentional usage of their wireless network
by outsiders.
Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. It improves data encryption
by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x.
WPA uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. WPA applies
IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an
external RADIUS database. The WPA protocol affords users with vastly stronger security than the
WEP protocol. It comes in two different varieties: WPA and WPA2. Always try to use WPA2 as it
implements the full version of the security standard while WPA does not.
