Nearly half of all U.S. employees use at least one Apple device at work, according to a new survey. Most of those gadgets lack common security protocols required by many enterprises. 51 percent of users’ Apple devices were secured by single-word passwords or numerical PINs, the survey found. 56 percent of Apple device users shared their passwords with others, and only 17 percent had company-supplied password managers. Almost 60 percent of the Macs represented in the survey were used to access confidential company information.”]
