Leaders of many public and private organizations face increased pressure to allow the use of personal mobile devices in their enterprises. This book provides an understanding of the increased risks that accompany the introduction of BYOD (Bring Your Own Device) into the enterprise. These risks are examined from the perspectives of the four primary stakeholders: the user, the carrier, the third party content provider, and the enterprise itself. The book discusses how this trend affects access, risk, and security and examines solutions to the conundrum of access and risk reduction. Cloud-based services are also discussed.
