The WPA protocol is now onto its third iteration (WPA3). In 2004, WPA2 was ratified, and it has been the predominant standard for secure wireless communication since then. WPA1 was an interim software-implementable solution for WEP designed to prevent the need for the immediate deployment of new hardware. Wi-Fi Protected Access (WPA) is the wireless security protocol developed to replace WEP. It is due to these potential variances in security standards that it is generally recommended that you always use a VPN on public WiFi networks to ensure that your data is strongly encrypted before it passes from your device and over the WLAN. Under these circumstances, you might actually connect using insecure WEP. While it is usually unlikely that you will run into networks running WEP as their primary form of security (because it has been surpassed for a very long time), it is theoretically possible that you might run into a network using an old router. Despite this, modern routers still support WEP for purposes of backward compatibility. For this reason, it was completely deprecated in 2004.Īt that time, WPA took its place as the new standard for robust consumer-level wireless encryption. Since then, many bugs have been discovered and developments in technology have rendered the protocol vulnerable.
This prevents data from being intercepted as it passes through the air – and ensures that other users are unable to eavesdrop on private and confidential data transmissions over the WLAN.īack in 1997, WEP was considered state-of-the-art. WEP functions by adding encryption to the data that is being transmitted wirelessly. It was developed to provide data privacy and security levels to a wireless local area network (WLAN) that is comparable to that of a conventional wired network.
Wired Equivalent Privacy (WEP) is a security standard for wireless networks that dates back to 1997.
