Wireless security protocols such as WEP, WPA, and WPA2 are used to protect wireless networks from unauthorized access. WEP (Wired Equivalent Privacy) was the first security protocol for wireless networks, but it is considered the least secure option because it uses a static encryption key that is easy to crack with modern tools. WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access II) are more secure options that use dynamic encryption keys that change frequently, making it much more difficult for attackers to gain access to the network. WPA2 is the most secure option available, as it uses the strongest encryption algorithms and provides protection against various types of attacks. However, it is important to note that the security of a wireless network depends not only on the security protocol but also on other factors such as strong passwords, disabling WPS, and keeping the router firmware up to date.
