Jelly Bean Security Enhancements Get Detailed
Smartphone security’s been on our minds today, after hearing about the lock screen exploit in iOS 6.1, and this evening Google has taken to its Android Developers blog to outline some of the security enhancements that it’s made in Android 4.2, including this week’s 4.2.2 update.
The brand new security tweak in 4.2.2 concerns USB debugging. While that can be a useful way to access your phone, especially if something goes wrong with the touchscreen, it can potentially leave your phone vulnerable to someone trying to bypass the lock screen. To combat that, 4.2.2 lets you create a computer-specific fingerprint, and only allow USB debugging when connected to such an authorized PC.
While many of those changes are only going to affect developers, it’s still nice to see Google pointing out just what it’s been doing to keep our Android smartphones safe and reliable.
