The permission model
As shown in the following screenshot, any Android application must be granted permis-
sions to access sensitive functionality, such as the Internet, dialer, and so on, by the user.
This provides an opportunity for the user to know in advance what functionality on the
device the application is trying to access. Simply put, it requires the user's permission to
perform any kind of malicious activity (stealing data, compromising the system, and so on).
This model helps the user to prevent attacks, but if the user is unaware and gives away a lot
of permissions, it leaves them in trouble (remember when it comes to installing malware on
any device, the weakest link is always the user).
