Benny got a $50 Polaroid Android Tablet. Is it secure? Leo says that mobile devices are inheritently more secure because they were developed long after we became aware of security issues. So they are sandboxed to prevent a lot of exploits. They're also very limited in what they can do -- they're more "dumb" than a desktop.
But Benny can do some things to further protect it. He shouldn't use it on an open network like a coffee shop. He should be using two factor authentication and LastPass. He should stick to the Google Play Store, and not use any other apps than what came on the tablet. That will keep it safe. And he should update the OS when updates are available.
