Security on Android
Android takes a multi-layered approach to security:
Prevent. Apps in Google Play are scanned continuously to block
harmful apps and policy violators. You can also choose to have
apps installed from other sources verified.
Control. App "sandboxes" keep apps from accessing other parts
of your tablet's operating system, or each other, unless you give
permission at installation. Screen lock and encryption help pre-
vent unauthorized access to the entire tablet.
Defend. Once identified, dangerous apps can be removed
This chapter includes information about the verify apps feature
(used both for prevention and defence), screen lock, encryption,
and other security features of your tablet.
Manage security settings
If your tablet has multiple users, each has separate security set-
tings. Some settings, such as encryption and trusted credentials
(certificates), are visible only to the owner.
