Fedora Vs. Ubuntu: Security Features Compared

Fedora Vs. Ubuntu: Security Features Compared

When choosing a Linux distribution for your server or desktop, security should be a top priority. Fedora and Ubuntu are two of the most popular Linux distributions, and both offer a range of security features to protect your system.


Fedora is a Red Hat-sponsored Linux distribution that is known for its stability and security. Fedora uses SELinux (Security-Enhanced Linux) to provide mandatory access control (MAC). This means that all processes and users are assigned a specific set of permissions, and any attempt to access a resource that is not explicitly allowed will be denied.

Fedora also uses AppArmor, which is a kernel-based security module that provides fine-grained access control. AppArmor can be used to restrict the actions that specific applications can perform, such as opening files, creating processes, or accessing the network.

In addition to SELinux and AppArmor, Fedora also includes a number of other security features, such as:

  • A firewall that can be configured to block unauthorized access to your system
  • A intrusion detection system that can detect and alert you to suspicious activity
  • A package signing system that ensures that all software packages are authentic


Ubuntu is a Canonical-sponsored Linux distribution that is known for its user-friendliness and wide range of available software. Ubuntu uses AppArmor to provide mandatory access control. This means that all processes and users are assigned a specific set of permissions, and any attempt to access a resource that is not explicitly allowed will be denied.

Ubuntu also includes a number of other security features, such as:

  • A firewall that can be configured to block unauthorized access to your system
  • A intrusion detection system that can detect and alert you to suspicious activity
  • A package signing system that ensures that all software packages are authentic


Fedora and Ubuntu both offer a range of security features to protect your system. However, there are some key differences between the two distributions.

  • Fedora uses SELinux, while Ubuntu uses AppArmor. SELinux is a more comprehensive security solution than AppArmor, but it can also be more complex to configure.
  • Fedora is a more security-focused distribution than Ubuntu. This means that Fedora is more likely to include the latest security patches and updates.
  • Ubuntu has a larger user base than Fedora. This means that there is more support available for Ubuntu, and it is easier to find documentation and tutorials.


Fedora and Ubuntu are both excellent choices for a secure Linux distribution. However, the best distribution for you will depend on your specific needs and requirements. If you are looking for a distribution with the most comprehensive security features, then Fedora is a good choice. If you are looking for a distribution that is easy to use and has a large user base, then Ubuntu is a good choice.## [Fedora Vs. Ubuntu: Security Features Compared]
