SSH, also known as Secure Shell, is a widely-used protocol for secure remote login to various computer systems. It employs cryptographic techniques to ensure the safety of services across unsecured networks. In essence, SSH creates a protected channel for communication within a client-server architecture over an insecure network, enabling clients to initiate text-based shell sessions on the server.
SSH comes in two versions – SSH-1 and SSH-2. While it is primarily utilized for remote login, SSH can also be employed for command-line login and execution. Unix-based operating systems frequently use SSH for shell account access, and Microsoft offers limited SSH support on Windows. SSH was initially designed to replace unsecured protocols like Telnet and to secure rlogin, rsh, and rexec protocols.
Currently, most hosting providers opt for SSH-2, which offers superior security features. Data transmission via SSH is heavily encrypted, safeguarding sensitive information like passwords from being intercepted. This ensures a secure channel for data transfer even on unsecured networks.
To use SSH, only basic software known as an SSH terminal or SSH client is necessary, which is compatible with multiple operating systems, including Windows, Unix, macOS, Safari, Solaris, and NetBSD. While Microsoft’s SSH support is limited, alternative software can be employed for additional assistance. For encryption purposes, SSH relies on a combination of public and private key methods.

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 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 Hosting
While SSH hosting offers numerous benefits, it also comes with a few drawbacks. Here are some of the disadvantages associated with SSH hosting:
Steeper Learning Curve:
For users who are not familiar with command-line interfaces, SSH hosting can pose a challenge. The learning curve may be steep for those who lack experience with Unix-based systems or terminal applications, potentially resulting in a longer setup and management process.
Limited Windows Support:
Although SSH hosting is compatible with multiple operating systems, Windows support is not as comprehensive as that for Unix-based systems. As a result, Windows users may need to rely on third-party software or workarounds for optimal functionality.
While SSH hosting provides robust encryption and secure access, it can also pose security risks if not configured correctly. For instance, using weak or default passwords, neglecting to update software, or failing to restrict user access can leave the system vulnerable to attacks.
With the greater control and flexibility offered by SSH hosting comes increased responsibility. Users must ensure that they properly maintain their servers, apply security updates, and monitor usage to prevent potential issues.
SSH hosting can consume more server resources than its graphical counterparts, such as web-based control panels. This increased resource usage may result in slower performance or additional costs for users who require more resources to meet their needs.
Potential for Human Error:
The command-line interface offered by SSH hosting can be unforgiving when it comes to errors. A single mistake in a command may lead to unintended consequences or data loss, highlighting the importance of careful management and thorough knowledge of the command-line environment.
While SSH hosting provides numerous advantages, it is essential for users to consider the potential drawbacks before choosing this option. Careful evaluation of one’s experience, needs, and available hosting providers can help ensure the best possible outcome when utilizing SSH hosting.
