Ahead of the official rollout for the Android 5.0 update now known as Lollipop, Google has detailed the increased security measures found in the operating system in order to address concerns regarding the depth of the changes. To begin with, Lollipop enables encryption by default and all the key communications applications such as calls and messages are now encrypted and can’t be accessed by other applications through another key feature below.
Google has also made extensive changes to the lock screen in order to encourage more people to use the tool for additional protection from theft and privacy control. In addition to PIN codes and passwords, users will be able to make use of trusted Bluetooth or NFC devices to unlock their device, or even smile at the user-facing camera in a second attempt to rollout camera-based locking after first rolling it out a few years ago.
Android 5.0 Lollipop will now sandbox apps from one another after years of applications being open to share data with each other without granular user control. As a part of the app sandboxing, the new Security Enhanced Linux Enforcing mode will be required for all applications on all devices as of the update, which means that apps will no longer be able to share information with other apps without the user’s explicit permission, which marks a definite change from past Android versions.
