Security can sometimes be overlooked in favor of functionality and profitability during device development. Yet, in a world that is becoming more networked and digitized, a device's security is key to its success, boosting customer satisfaction and improving the manufacturer's competitive edge. Dr. Dominik Merli, professor of IT security at the Technical University of Applied Sciences Augsburg (THA) and head of THA’s Institute for Innovative Safety and Security (THA_innos), reports on the need for security with his book Engineering Secure Devices: A Practical Guide for Embedded System Architects and Developers.
