World Wide Web HTTP

HTTP (HyperText Transfer Protocol) is a protocol used for transmitting hypertext requests and information on the internet. It is the foundation of any data exchange on the Web and a protocol used for transmitting web pages. HTTP operates on port 80 and is essential for web browsing and accessing web resources.

What is World Wide Web HTTP

HTTP (HyperText Transfer Protocol) is a protocol used for transmitting hypertext requests and information on the internet. It was developed by Tim Berners-Lee and his team at CERN in the early 1990s. HTTP is the foundation of any data exchange on the Web and a protocol used for transmitting web pages.

HTTP operates on port 80 and is essential for web browsing and accessing web resources. When a user enters a URL in their web browser, an HTTP request is sent to the server hosting the website. The server then responds with the requested web page, which the browser renders for the user to view.

HTTP is a stateless protocol, meaning each request from a client to server is treated as an independent transaction that is unrelated to any previous request. This simplicity makes HTTP a robust and scalable protocol, but it also means that additional mechanisms, such as cookies and sessions, are needed to maintain stateful information across multiple requests.

World Wide Web HTTP runs on TCP and UDP port 80 and is official IANA port.

Security risk

If port 80 is open and the HTTP service is running, it can be a target for various types of cyber attacks, such as DDoS attacks, man-in-the-middle attacks, and web application vulnerabilities. Ensuring that the HTTP service is properly secured and monitored is crucial to mitigate these risks.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 80. Use StackChanges to monitor if the World Wide Web HTTP port is closed and stays closed. StackChanges will send an alert if port 80 is open again.
