An anonymous reader writes: Due to a concern that smartphones (and other electronic devices) could be infected with malware and used to spy on sensitive information, my employer has recently banned all personal electronic devices from their spaces. The concern comes from articles like this one. My question to slashdot readers: How reasonable is this concern? How can this sort of malware be prevented from showing up on our devices? Is there a way to educate employees about preventing this sort of thing rather than banning the devices altogether? This current reality is that people have started to rely on having their smartphones with them at all times for things such as receiving emergency calls from day cares and schools, making personal calls during normal working hours (i.e. to make doctor's appointments), accessing password managers, and scheduling calendar events.
