COMPUTER NETWORKING

Detailed explanation-1: -Port 80 is the port number assigned to commonly used internet communication protocol, Hypertext Transfer Protocol (HTTP). It is the default network port used to send and receive unencrypted web pages.

Detailed explanation-2: -It is essential to know the difference between the two. HTTPS is secure and is on port 443, while HTTP is unsecured and available on port 80. Information that travels on the port 443 is encrypted using Secure Sockets Layer (SSL) or its new version, Transport Layer Security (TLS) and hence safer.

Detailed explanation-3: -Port 80 isn’t inherently a security risk. However, if you leave it open and don’t have the proper configurations in place, attackers can easily use it to access your systems and data. Unlike port 443 (HTTPS), port 80 is unencrypted, making it easy for cybercriminals to access, leak and tamper with sensitive data.
