By rooting the Samsung Galaxy Note Pro 12.2 tablet with the CF-Auto-Root one-click rooting tool, you are getting the chance to grant rooting rights to the apps that need it to run. The Android operating system is very secure without root access because no apps can get into the root file system. However, with a rooted Android, you could grant rooting permissions to malware, and that becomes a problem if the malware then chooses to exploit those rooting permissions and start browsing through your tablet.
Coming across malware is rare and granting malware rooting rights is much rarer yet again because it takes an additional human error in not identifying what malware is. The CF-Auto-Root tool installs and enables the SuperSU on the smartphone and that SuperSU stops everything in its path. So the act of rooting itself does not make a device less secure. It is what happens next. Everyone with a thorough understanding of what they are installing can use a device with SuperSU without any malware getting into the system because they do not ever let it in. However, those with less knowledge and understanding might grant rooting permissions from SuperSU to malware without knowing it is malware.
As long as you browse the Google Play Store for your apps and install apps that are names you know you can trust online then there is never any worry about installing malware because you know those apps you are installing is not malware. For example, if I open the Google Play Store with my newly rooted Samsung Galaxy Note Pro tablet and download the Titanium Backup app and then nothing else for the day I know that I do not have malware because Titanium Backup is a trusted app and I downloaded the official app from a source of confidence. It is also very easy once you know what to do when you are online.
