CloudLinux, specialized Linux distribution designed specifically for shared hosting environments, is the ideal solution to optimize server performance, enhance security, and improve user isolation.
CloudLinux OS Shared is fully compatible with cPanel, DirectAdmin, and Plesk control panels and for all other control panels, integration is still possible via tools provided by CloudLinux.
If you are looking to improve security on your shared hosting environments with easy integration into Control Panels, this is a excellent option that not only applies to hosting companies, but sensitive applications that share in a higher level the resources, or need for example a older version of PHP!
What is CloudLinux?
CloudLinux is a Linux distribution designed to improve the security, performance, and overall efficiency of shared hosting servers. Its primary aim is to isolate individual users, ensuring that one customer’s behavior or resource usage doesn’t negatively impact others on the same server. This results in a more stable and secure hosting environment for everyone involved.
Some of its main features are:
1. Enhanced Security with SecureLinks
CloudLinux offers SecureLinks, a kernel-level technology. It blocks symbolic link attacks. These attacks are one of the most common exploits targeting web servers.
SecureLinks blocks these attacks by preventing malicious users from creating symbolic links to unauthorized files. As a result, it strengthens server security. It also reduces the risk of attackers accessing sensitive data or configuration files, such as PHP settings or user configurations. Consequently, this adds an additional layer of protection to the server.
2. CageFS: Ultimate User Isolation
In shared hosting environments, it’s essential to isolate users to prevent security breaches. CageFS creates a virtualized file system that isolates each customer, ensuring that users can’t see or access files, processes, or data belonging to other customers.
This level of isolation protects sensitive information and prevents attackers from escalating privileges or discovering vulnerabilities through other users’ configurations.
Key Benefits of CageFS Include:
- Users can only access their own files and data.
- Users cannot detect the presence of other customers on the server.
- Critical server configuration files remain hidden from users.
- It prevents privilege escalation and unauthorized access.
3. HardenedPHP: Securing Legacy PHP Versions
Some websites still rely on older versions of PHP, such as PHP 5.6, 7.0, and 7.1, which no longer receive official support or security updates from the PHP.net community. CloudLinux’s HardenedPHP ensures that even these outdated PHP versions remain secure by patching known vulnerabilities. So, while not advised, if you need these older versions, we can offer support for legacy applications without compromising the security of the server, making CloudLinux an invaluable tool for maintaining compatibility and security.
4. Python Selector: Flexibility for Python Developers
This feature allows you to select their preferred version of Python for their applications, as well as install additional modules to support their specific requirements.
By using mod_passenger to optimize Python application performance, the Python Selector ensures that your customers enjoy the best possible user experience.
5. Ruby Selector: Tailored for Ruby on Rails Applications
Similar to the Python Selector, CloudLinux offers a Ruby Selector. It allows users to select the specific Ruby version required for their applications. Whether it’s Ruby on Rails, Sinatra, or another Ruby-based framework, the Ruby Selector provides flexibility. Developers can install the necessary gems and modules for their projects.
By utilizing mod_passenger for optimized performance, the Ruby Selector delivers fast and efficient Ruby-based application hosting.
Why is CloudLinux important?
CloudLinux isn’t just about security, but is also delivers a better, more reliable hosting experience. By isolating users, securing legacy applications, and providing flexibility for programming languages like Python and Ruby, CloudLinux offers hosting providers a powerful tool for maintaining high server performance, stability, and security.
