SSH or Secure shell is a protocol used mainly for remote login applications for different computer systems by many users. It uses a cryptographic network protocol for securely using services over an unsecured network. In short, in a client server architecture SSH provides a secure channel over an unsecured network. It connects a client with the server. It starts text-based shell sessions on the server.
There are two types of SSH – SSH-1 and SSH-2. Other than remote login applications, other examples where SSH is used is command line login and execution. SSH is most commonly used to access shell accounts on Unix operating systems. Microsoft provides limited use and support for SSH on Windows as well. SSH was originally created to replace Telnet which was an unsecured protocol. It was then also used for securing rlogin, rsh and rexec protocols.
Out of the available versions, most hosting companies today use SSH-2. SSH-2 has more enhanced security. Transmission of all the data on SSH is heavily encrypted. This protects password or other information from being sniffed. Thus, SSH provides the data a secure channel for transmission even if the network is unsecured.
Software requirements for using SSH are limited. A basic software called SSH terminal or SSH client is required. This is available for all operating systems like Windows, Unix, MAC, Safari, Solaris, NetBSD etc. Microsoft does not support SSH extensively however, there are other software that can be used to provide support to it. For its encryption, SSH uses both public and manual key.
With the help of SSH access, a user can easily log in to the web hosting account and manage the website. This is done using UNIX or Linux instructions. Many website maintenance tasks including backups, compression of files, data transfer etc. can be performed at ease. Scheduled tasks like editing of system files and file permissions can also be taken care of.
Easy Installations of Applications
Applications like Drupal, WordPress, Prestashop and Joomla! are very popular among website designers today. Also everyone generally prefers one-click installations or easy methods of installing these applications on their devices. SSH access enables the users to download these applications directly, unpacked them and install them with ease. Users can also log in to MySQL and access the required databases.
Simplified Server Management
There is a lot more to SSH hosting than just using the command line to login or access your server. The resulting workflow is faster and easier when compared to that using a graphical user interface. Accessing and managing the server’s files becomes simple and efficient. This is mainly because just a few commands can be used to create folders, transfer files and perform other file operations.
Added Security Using SSH
SSH enables the user to setup a SSH tunnel. A SSH tunnel is nothing but a secure space through which encrypted files can be transmitted with a guarantee that no third party is able to reach these files during the transmission process.

The initial versions of SSH did not provide as much security as the latest versions. The limitations in these older versions were initially dealt with using patches. However, they still remained quite vulnerable and these have now become obsolete. The latest version SSH-2 is now used as the standard in the industry. This version has improved the security to a great extent. In spite of all this, providing the server with 100% security is almost impossible.
Most reputed hosts offer SSH access on all of their plans. However, VPS and dedicated server clients get root access to SSH, giving them a lot more flexibility. For using SSH, no particular programming or technical experience is required. Just a few setting adjustments need to be made to connect to a remote server using SSH. Then login through FTP is required. SSH is being used in on the cloud platform too. It is helping to address a lot of security issues being faced by users of cloud computing.
Disadvantages of SSH
In spite of the security that comes with digital certificates and encryption, SSH still has some vulnerabilities that can cause digital attacks.
SSH is not ideal for continuous long term data transfers or bulk transfers. Larger files being transferred can cause SSH spikes.
Heavy use of SSH can decrease the performance of your website. This is mainly because SSH can cause spikes in the CPU and bandwidth if large amounts of data are transferred in one session. Spikes can also be caused due to debugging.
