VPN security from CERT

VPN

VPN stands for virtual private network. VPNs are a secure way to use the internet as an extension of a private network. They use encryption and a special internet protocol to create a “tunnel” through the internet from one point to another. This traffic cannot be accessed by those unable to connect to the VPN. Businesses frequently use VPNs to secure private network traffic moving between two geographically distinct offices, or between remote employees using laptops and the home office.

WEP

WEP stands for wired equivalent privacy, a security protocol designed to provide a wireless network with a level of security and privacy comparable to that of a wired LAN. In WEP, data moving between computers and access points is encrypted.

Wi-Fi

Wi-Fi is short for wireless fidelity. The term applies to wireless networks that employ 802.11-type security. An organization called the Wi-Fi Alliance coined the term. This organization tests wireless products work together and certified those that pass as “Wi-Fi certified” (a registered trademark).

WPA

WPA stands for Wi-Fi protected access. Like WEP, WPA is a security protocol designed to provide a wireless network with security and privacy. WPA provides stronger data encryption and better user authentication than WEP.
