config.xml
android-minSdkVersion (Android only)
Minimum SDK version supported on the target device. Maximum version is blank by default.
This template sets the minimum to 14.
<preference name="android-minSdkVersion" value="14" />
<access ...> (All)
This template defaults to wide open access.
<access origin="*" />
It is strongly encouraged that you restrict access to external resources in your application before releasing to production.

Content Security Policy (CSP)
The default CSP is similarly open:
<meta http-equiv="Content-Security-Policy" content="default-src * 'unsafe-inline'; style-src 'self' 'unsafe-inline'; media-src *" />
Much like the access tag above, you are strongly encouraged to use a more restrictive CSP in production.
A good starting point declaration might be:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: 'unsafe-inline' https://ssl.gstatic.com; style-src 'self' 'unsafe-inline'; media-src *" />
For more information on the Content Security Policy, see the section on CSP in the Cordova Whitelist Plugin documentation.
