Answer

Disable installation from unknown sources to block sideloading
Disabling application installation from unknown sources prevents Android users from sideloading unverified application files obtained outside approved app marketplaces.

Step-by-Step Solution

1
Identify the threat
Unapproved third-party software packages downloaded from external websites (sideloaded applications) pose security risks.
Installing apps outside official marketplaces circumvents OS security checks and enterprise management controls.
2
Select the appropriate security restriction policy
Disabling the option to install applications from unknown sources restricts software installation strictly to authorized repositories.
This setting directly prevents users from executing or installing unauthorized package files on the mobile OS.
