Computing and mobile computing are, to an ever-growing degree, the same thing. According to research by StoneTemple, at the beginning of 2018, 63% of Web traffic comes from mobile devices; they expect the number to pass 2/3 of all traffic by the end of the year.
Most users, and most security professionals, seem to think that mobile platforms are inherently more secure than traditional desktop and laptop computers. In many circumstances that's correct, but that assumption can lead to behaviors that carry significant risks.
Fortunately, there are steps a security team can take secure mobile devices: Some of these are actions that the security team should take, while others are actions that should be taught to users. Many of these steps fall squarely in the "it just makes common sense" category of things. That doesn't mean that security pros and users alike don't need a reminder to check for each of these to be on their list of positive behaviors — and on the list of results to be enforced by policy on all devices.
There are many behaviors that can contribute to mobile device security or risk. We'd be interested in hearing about the behaviors that you see as important — but that didn't make our list. Use the comment section to let us know what we missed.
