Clear Linux, as is mentioned on the project's website as one of its standout design features, places a priority on security, considering it in its core design instead of as an additional consideration outside and after the core design.
Clear Linux places a priority on security, considering it in its core design instead of an addition outside the core.
Below are some of the features highlighted on the project's website.
Like the most security conscious distributions, openSUSE and Fedora, Clear Linux requires authentication when accessing external partitions on the same computer. But unlike these, or any other distribution, Clear Linux also requires authentication when connecting an external USB storage device.
Some of the security features combined with the lack of certain widely used software may require users to build and install third-party kernel modules. In my case, in order to use VirtualBox, I had to install the generic version downloaded from the VirtualBox site. -- downloaded from the VirtualBox site, which requires certain kernel modules distributed by VirtualBox. As the kernel and all kernel modules are verified by the Clear Linux OS, building the VirtualBox modules fails during VirtualBox installation.
In order to use third-party kernel modules, it is possible to disable enforcement of kernel signature verification by including
module.sig unenforce in the file /etc/kernel/cmdline.d/allow-unsigned-modules.conf and running sudo clr-boot-manager update
sudo mkdir -p /etc/kernel/cmdline.d echo "module.sig_unenforce" | sudo tee /etc/kernel/cmdline.d/allow-unsigned-modules.conf
sudo clr-boot-manager update sudo reboot
