WPA, which stands for Wi-Fi Protected Access, is a recognized security protocol specifically designed for securing wireless networks. It offers improved security over its predecessor, WEP (Wired Equivalent Privacy), by using stronger encryption methods and providing features to enhance overall network security. WPA, along with its successor WPA2, is widely used to protect the integrity and confidentiality of data transmitted over wireless networks.

WEP is also a recognized protocol; however, it is considered outdated and insecure due to its vulnerabilities to various types of attacks. Despite being a standard at one time, WEP has largely been supplanted by WPA due to its numerous security flaws.

In contrast, SSL (Secure Sockets Layer) and HTTP (Hypertext Transfer Protocol) are not specific to wireless networks. SSL is a cryptographic protocol designed to provide secure communication over a computer network, often used to secure web traffic but not limited to wireless scenarios. HTTP is the foundation of data communication for the World Wide Web and does not inherently include any security mechanisms.
