Submission + - Android KitKat could be a strong deterrent to cybercrime and spying (networkworld.com)
With each new Android release, Google adds more security features to harden Android. Two security features in Android 4.4 KitKat are particularly notable because they are Linux kernel developments. Security-enhanced Linux (SELinux) policies are fully enabled in KitKat, and dm-verity was added. Both features improve the integrity and trust of the Android operating system.
This builds on Google's earlier work to tighten Android’s defenses against attackers, such as full-disk encryption (dm-crypt) added to Android 3.x and Address Space Layout Randomization (ADLR) and Data Execution Protection (DEP) in Android 4.1.
