Our team’s goal is simple: secure more than two billion Android devices. It’s our entire focus, and we’re constantly working to improve our protections to keep users safe.
Today, we’re releasing our fourth annual Android Security Year in Review. We compile these reports to help educate the public about the many different layers of Android security, and also to hold ourselves accountable so that anyone can track our security work over time.
We saw really positive momentum last year and this post includes some, but not nearly all, of the major moments from 2017. To dive into all the details, you can read the full report at: g.co/AndroidSecurityReport2017
Google Play Protect
In May, we announced Google Play Protect, a new home for the suite of Android security services on nearly two billion devices. While many of Play Protect’s features had been securing Android devices for years, we wanted to make these more visible to help assure people that our security protections are constantly working to keep them safe.
Play Protect’s core objective is to shield users from Potentially Harmful Apps, or PHAs. Every day, it automatically reviews more than 50 billion apps, other potential sources of PHAs, and devices themselves and takes action when it finds any.
Play Protect uses a variety of different tactics to keep users and their data safe, but the impact of machine learning is already quite significant: 60.3% of all Potentially Harmful Apps were detected via machine learning, and we expect this to increase in the future.
