So I recently went through the wonderful adventure of fixing the
/usr/bin/sudo file after it's permissions have been changed. This was on a system where it had been intentionally reconfigured to make it difficult obtain root through the other normal routes.
Now to prevent this in the future, I could just run these commands on a root cron job:
chown root:root /usr/bin/sudo chmod 4755 /usr/bin/sudo
However, ideally this set of commands would not only fix the sudo file, but all the files needed for an effective root.
My Question: Is there an existing script or library I can install to make sure effective root is maintained?
This is for Fedora 26 running on VM.
