The latest iteration of the Android operating system codenamed KitKat has been released on October 31st and, according to the changelog, it comes with quite an array of security features. The full list of security additions is already up on the Developers website and covers features from enhanced sandboxing to certificate pinning or boot verification. We took a look at the new security features as they show up in the AOSP (Android Open Source Project) version of KitKat and here is a rundown of what we learned:
