Omar has recently been hired as the HIM director at a large medical center. He realizes that he has a number of employees whose job duties would allow them to work from home. Because his boss has asked him for a space reduction proposal, he recognizes the need to implement a work-at-home program for his employees. What steps should Omar take in developing a security program for the employees who will work from home? Develop a checklist of considerations, along with a list of resources that would facilitate his security program.
