Securing is important, especially if you have bits facing the public internet. After I installed the new version of the OS, which is nice and extremely fast, I found a few security issues that I needed to fix. I open my ssh to the world as a gateway to my network and use it as a control center for my home. Below are some of the common bits I do to every linux machine. It would be nice if others would add to this thread what they do to secure their UDOO as my list doesn't even scratch the surface. My list more or less goes over the very bare essentials. Change ubuntu user's Password, default is ubuntu use udoo configurator or command line passwd If you have the know how change the default user name. Change root user's password, default is ubuntu ( Use command line passwd as root ) Code: # sudo passwd Enter your ubuntu password Enter the new root password Confirm new root password SSH Allows root login In /etc/ssh/sshd_config change PermitRootLogin to no. Change Code: PermitRootLogin yes to Code: PermitRootLogin no Save the file and restart ssh: Code: # restart ssh Recommended: change ssh port VNC default password Change your vnc password through udoo configuration. This wouldn't hurt me as I tunnel my vnc through ssh, but it is still a good idea. Resource Links http://ubuntuforums.org/showthread.php?t=510812
