I think its more important to spread trust and awareness about installing apps on mobile devices, for personal use, its trying to ensure that people don’t go clicking and installing anything. With Google and Apple patrolling their stores, its better than what it was years ago, but still not 100% trust worthy. All this is easier said than done yes, but ensuring that apps being installed from trusted sources is a good start.
From the enterprise side of things, ensuring that MDM is in place will also help, especially tied in with endpoint protection tooling.
