Google Details Security Enhancements in Android 4.2.2

Following the release of Android 4.2.2, Google has detailed the security enhancements of the updated mobile operating system.

In addition to an improved random number generator, Google has incorporated more secure ways for apps to utilize Javascript. Google has also changed the default method by which access is granted to content providers, thereby preventing potential unauthorized access.

Additionally, a new option to USB debugging in Android 4.2.2 has been integrated; it allows users to lock USB debugging mode apart from when connected to a PC. Elsewhere, it offers general improvements for performance and stability for several Nexus devices (GSM Galaxy Nexus smartphone, the Nexus 7 and the Nexus 10 tablets are the devices to thus far receive the update), as well as a streaming audio issue.

The latest Android Jelly Bean upgrade comes after a study found that Google's mobile platform is increasingly becoming a growing target for malware. Android 4.2, meanwhile, introduced an updated malware scanner that checks third-party apps.
