Secure Shell Hosting, more popularly known as SSH, is a safe Linux protocol which is deployed to access other computers through a remote terminal. Hence, using SSH protocol, you will be able to access a server which is actually located at a huge distance from you. This protocol makes both command execution and remote logging hassle free procedures altogether.
Why SSH is better than Telnet?
Telnet has been in existence for more days in comparison with SSH. It served well to facilitate communication with a distinct command like interface. However, what you could have sent during the communication process was in plain text format only. That’s where SSH scores more than Telnet.
Security is in the name of this protocol, but, many questions that how secure SSH is exactly! SSH is based on key based cryptography and thus the data transmission between host to client or vice versa is handled in a secure manner and all of the session data is properly authenticated as well. Therefore, it serves as a bridge between two insecure networks which don’t have any sort of trust established between each other.
Some of the basic features of SSH are:
Various Authentications: You can include authentication for various things such as: keyboard interactive, Kerberos, passwords and public keys.
Encrypted Session Data and Logs: Through this, the login and session data of various users in a website are encrypted and thereby remain safe.
Exec Request: This works great for the network operations mostly. Therefore, with SSH, you can execute a program on a server similar to a remote console. However, terminal encoding is not accomplished through SSH; rather raw input and output data are sent.
Remote Console: You can log in to the remote server through this window open for you at your system. After logging in, you can perform several tasks of your choice as well.
SFTP: This stands for Standard File Transfer Protocol and is one of the latest ones in the brigade. This is getting more popular with every passing day, mainly because of the versatility it offers.
Port Forwarding: In general, TCP connections are found to be vulnerable to external attacks. With SSH, you get port forwarding enabled and thus you can give these connections a better security.
Apart from these aforementioned basic features, SSH often comes up with VBScript and printing utilities as well. For a more secured environment, you can also update to SSH2; this crucial upgrade is known to combat even the weirdest security risks.
