WHAT IS A FIREWALL IN NETWORK SECURITY

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The secure version of HTTP runs on port
A
80
B
443
C
143
D
3389
Explanation: 

Detailed explanation-1: -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-2: -ports 80 and 443 are standard HTTP and HTTPS ports. They can be used by other applications such as IIS or Apache.

Detailed explanation-3: -The Internet Engineering Task Force (IETF) recognizes the TCP port number 443 as the default HTTPS protocol. It provides an encryption algorithm for exchanging information between web servers and browsers. HTTPS port 443 works by securing network traffic packets before the data transmission occurs.

Detailed explanation-4: -HTTP is unsecured while HTTPS is secured. HTTP sends data over port 80 while HTTPS uses port 443. HTTP operates at application layer, while HTTPS operates at transport layer. No SSL certificates are required for HTTP; with HTTPS, it is required that you have an SSL certificate and a CA signs it.
