Over the years, Google has been shoring up security on Android in a bid to make the operating system more attractive to governments and businesses, and to reduce the threat of malware for regular users. Unfortunately, these changes often come at the expense of flexibility in our beloved platform. As we close in on the next major release of Android, due to be announced next month, SuperSU developer Chainfire has discovered a set of commits to the Android Open Source Project (AOSP) that may seriously impact some of the functionality currently enjoyed by many root users.
Yet another facet of KitKat worth pointing out today is the addition of new security enhancements to the OS. Security is one area that's frequently sensationalized with Android - it seems that every few days a scare story about Android malware creeps onto my Google News page. Google's eliminating security arguments (and possible arguments) one at a time, though, and has made a few key enhancements this time around.
First among them is a change to SELinux.
These days, it seems like everybody is trying to make Android more secure. As usual, rooting and modding are often casualties of this effort. Just over a month ago Android 4.3 broke the existing model for root, forcing updates to existing methods, and now Samsung is rolling out updated Android 4.2.2 firmwares for the Galaxy S 4 which fully enable the company's heavily secured KNOX environment. Fortunately, Chainfire is already on top of it and has updated his popular root software, SuperSU, to be compatible with the new system.
We've got an LG Nexus system dump and endless desire to spoil every Googley surprise we can. Today's edition of the Android 4.2 Teardown could be alternatively subtitled "The Super-Serious Security Edition," because we're talking about the sort of stuff that should make your sysadmin jump for joy.
Please keep in mind this is just as forward-facing and time-ambiguous as all my other teardowns. This is a list of new stuff in the 4.2 dump, not a list of "confirmed for 4.2" features.
