Smartphone security

The smartphone should have the so-called screen lock, so that in case the phone is lost, the personal information does not get available to third parties.

Applications, downloaded from suspicious sources should not be installed on the smartphone as they may contain malware programs.

When installing the application, attention should be paid to the rights the application requires, as some of them might request unnecessary function for wrong purposes.

The smartphone should not be rooted/jailbroken, as this gives access to full phone control  to malware programs.
