Wi-Fi security protocols are designed to protect your network from unauthorized access, eavesdropping, and data theft. There have been several security protocols developed over the years, each with its own set of features and vulnerabilities. The most common Wi-Fi security protocols are:
WEP (Wired Equivalent Privacy)
WEP was the first security protocol introduced for Wi-Fi networks. It was designed to provide a level of security equivalent to that of a wired network. However, WEP has several weaknesses, including a static key and a small key size, making it vulnerable to hacking. WEP is no longer considered secure and should not be used.
WPA (Wi-Fi Protected Access)
WPA was introduced as a replacement for WEP. It uses a dynamic key and a larger key size, making it more secure than WEP. However, WPA is still vulnerable to certain types of attacks, such as the KRACK attack.
WPA2 (Wi-Fi Protected Access 2)
WPA2 is the most widely used security protocol today. It uses the Advanced Encryption Standard (AES) and a larger key size, making it more secure than WPA. However, WPA2 is also vulnerable to certain types of attacks, such as the KRACK attack.
WPA3 (Wi-Fi Protected Access 3)
WPA3 is the latest security protocol, introduced in 2018. It uses the Simultaneous Authentication of Equals (SAE) protocol and a larger key size, making it more secure than WPA2. WPA3 is also designed to provide better protection against certain types of attacks, such as the KRACK attack.
