SSH or Secure Sheel is a network protocol which employ a cryptography to communicate data on network devices to make it safer. In its concept, the use of free SSH must be supported by a device a server or client computer that exchanges data. Both server or client computer must have SSH Server from the side of the client-server SSH Server for the recipient computer. Widely used on Linux and Unix-based operating system to access Shell accounts, Secure Shell (SSH) is well-designed as a Telnet substitute and other non-secure remote shells, that actually send information, especially passwords, in the form of simple text that makes it easy to deny.
The SSH function is can be used to replace telnet, rlogin, FTP, and rsh, one of its main functions is to ensure the security in transmitting data on a network. SSH It’s widely used by various network admins in several parts of the world to control the web and other types of networks such as WAN. This SSH function is actually made to replace the previous protocol which is very vulnerable to data theft through harmful malware. These protocols such as rlogin, telnet, and protocol rsh. The other functions of SSH, are:
- Encrypt the data sent
- As a protocol for exchanging data in a network
- Authentication a mechanism to ensure the sender and receiver are correct and safe
- Ensuring the confidentiality of the power sent to that it is only known by the recipient and the sender
The benefits of using an SSH account is to increase the level of data security on your computer when you’re connected to the internet. SSH Account will become an intermediary third party for your internet connection that will detect any insecure site or data flow through accessing internet. SSH will provide the encryption for all readable data, then will send it to other servers.
Besides being able to encrypt data, SSH also has the ability to do Port Forwarding which allows us to get the following benefits, such as:
- Connect to TCP application, for example. The web server, mail server, FTP server will be more secure
- To connect by bypassing a local firewall or proxy
The second benefit above is what the often search by the internet users and use it for the benefits of internet access. By using an SSH Account, we may also manage VPS for hosting or other functionally. Using an SSH Account to secure your internet connection will not ensure the enhancement of your internet speed 100%. However, by using an SSH account, the IP that you use will be static and you are able to use it privately with the only user in the SSH account.
This SSH protocol has many functions, besides the tunneling function that we often use. We can also use the SSH for SFTP, SOCKS4 / 5 proxies or we can also use it to manage your VPS or hosting especially VPS with Linux OS like CentOS. The use tunneling of SSH we can use SSH clients such as Bitvise Tunnelier or Putty for windows operating system. To get this account and usage from SSH, we can get free SSH account on some sites.
Usability Of SSH
SSH is designed to replace telnet and FTP protocols. SSH is a versatile product that designed to do many things, most of which are the creation of a tunnel between hosts. Two important SSHs are console login and secure file transfer. But with SSH you also get the ability to create source tunnel to pass HTTP, FTP, POP3, and anything else via SSH tunnel. To using the SSH, you may create the free SSH account that you can get from some sites.
