Security Based OS ?

[NobodyNew1]

Any Linux image available for the PinePhone is more secure than Android.

You can look into hardening the kernel and other applications. You may also consider AppArmor, SELinux, firejail and other security measures you want to use. Some are built into a given distribution, others requires manual intervention, and a few will be incompatible with each other.

A couple of Wiki articles regarding hardening:

• Debian
  
• Arch
  

For what it's worth, I believe Mobian (Debian), postmarketOS (Alpine Linux) and Fedora will be the most secure. Ubuntu Touch by UBports has an immutable filesystem, if you value that.

Review the list of operating systems and go from there.

Thank you !!! I appreciate your response. Like some I'm new to linux and the pinephone, I look into and read more about Mobian and PMOS.
