#Wifi wep vs wpa overhead professional
The ISC2 common body of knowledge (CBK) is the basis for the Certified Information Systems Security Professional (CISSP) certification. So I tried to make it easy to read, rather than too technical. I remember when writing it, my audience, although technically savvy did not a have a strong background in cryptography or security. The first half is background and theory, and the second half of a practical example. I have divided the material into two parts. I’ve since moved onto other IT disciplines, but I hope that this article is of some use to those looking for an introduction to WIFI security. Data transmissions are encrypted with an automatically generated key.Like my posts on IT governance standards, I produced this training material some time back when I was doing a lot of IT security work. Every wireless client has a user login on the RADIUS server, and the wireless modem router has a client login on the RADIUS server. The authentication server is called Remote Authentication Dial In User Service (RADIUS). WPA-802.1x is enterprise-level security and requires an authentication server to recognize and authorize client access.

WPA client software should have instructions about configuring their WPA settings. The product documentation for your wireless adapter and WPA2-PSK clients get higher speed and security, and WPA-PSK clients get decent speed and security. NETGEAR recommends mixed mode because it provides broader support for all wireless clients.
WPS-PSK + WPA2-PSK mixed mode is the preconfigured security mode on the wireless modem router. Then it dynamically varies the encryption key. WPA2-PSK uses a passphrase to authenticate and generate the initial data encryption keys. WPA2-PSK gets higher speed because it is usually implemented through hardware, while WPA-PSK is usually implemented through software. It is advertised to be theoretically indecipherable due to the greater degree of randomness in encryption keys that it generates. WPA-PSK uses Temporal Key Integrity Protocol (TKIP) data encryption, implements most of the IEEE 802.11i standard, and is designed to work with all wireless network interface cards, but not all wireless access points. This option uses a passphrase to perform the authentication and generate the initial data encryption keys. WPA-PSK uses a much stronger encryption algorithm than WEP so it is harder to decode. This seal means the product is authorized by the Wi-Fi Alliance ( ) because it complies with the worldwide single standard for high-speed wireless local area networking. WPA encryption is built into all hardware that has the Wi-Fi-certified seal. The Wi-Fi alliance highly recommends against using WEP and plans to make it obsolete. Use this mode only, when you have a very old legacy wireless client that does not support WPA-PSK. WEP uses an old encryption method and can be easily decoded with today’s powerful computers.

WEP and WPA, are standards for encrypting data that is transmitted over wireless (WiFi) networks, to prevent eavesdropping.
