Is port 443 an SSH?
To bypass these connectivity issues, you can use SSH over the HTTPS port (port 443) instead of the default SSH port (port 22). Port 443 is generally open in most network environments, as it is the standard port used for HTTPS traffic.Port 443 is the standard port for HTTPS, the secure version of HTTP. HTTPS is used by websites and other online services to protect your data from being intercepted by eavesdroppers. Imagine port 443 as a secure tunnel between your web browser and a website.port 22

SSH port 22

The port is used for Secure Shell (SSH) communication and allows remote administration access to the VM.

What is the difference between port 22 and 443 : You use port 22 for SSH to make secure connections to remote devices and run commands. You use port 443, on the other hand, for securely transmitting sensitive data such as credit card numbers in a web browser using Secure Socket Layer (SSL) over HTTPS.

Is 443 the only SSL port

However, the two most common ports used in secured web browser communication are port 443 and port 8443.

Does SFTP use port 443 : SFTP Requires ports 22 or 990 to be open, which is prone to malware including the likes of infamous offenders like Wannacry, Sasser, Nimda, Petya/NotPetya, and more.

Port 443 is designed for secure, encrypted traffic (HTTPS protocol), so it will look for some SSL / TLS configuration. If it doesn't find any, you will likely receive an SSL connection error.

SSL/TLS does not itself use any port — HTTPS uses port 443. That might sound kind of snooty, but there's an important distinction to be made there. Think of SSL/TLS as more of a facilitator. It enables other protocols, like HTTPS or DNS over TLS.

Is SSH TCP or UDP port number

Is SSH over TCP or UDP SSH usually runs over TCP. That being said, RFC 4251 specifies that SSH transmission layer protocol “might also be used on top of any other reliable data stream”. SSH protocol's default settings are to listen on TCP port 22 for connections.443

Normally, SSH uses port 22 while SSL uses port 443. SSL is used predominantly for securely transmitting critical information like in credit cards and banking. On the other hand, SSH is for securely executing commands across the internet.

SFTP port number is the SSH port 22 (follow the link to see how it got that number). It is basically just an SSH server. Only once the user has logged in to the server using SSH can the SFTP protocol be initiated.

Can I use 443 without SSL : Port 443 is designed for secure, encrypted traffic (HTTPS protocol), so it will look for some SSL / TLS configuration. If it doesn't find any, you will likely receive an SSL connection error.

Is 443 SSL or TLS : 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.

Is SSH and SFTP the same port

Since SFTP runs over the SSH protocol as a subsystem, SFTP uses port 22 by default. The SSH server at port 22 listens for client requests. The port number can be changed, if desired, for testing or other reasons.

SSH (Secure Shell) is a network protocol enabling secure connections between two systems. SFTP (SSH File Transfer Protocol) allows secure file transfer, leveraging SSH for encrypted connections. While SSH is designed for secure command execution, SFTP focuses on secure file transfers.Port 443 is used explicitly for HTTPS services and hence is the standard port for HTTPS (encrypted) traffic. It is also called HTTPS port 443, so all the secured transactions are made using port 443. You might be surprised to know that almost 95% of the secured sites use port 443 for secure transfers.

Is SSH HTTP or TCP : An SSH server, by default, listens on the standard Transmission Control Protocol (TCP) port 22.
