Securing Edge Devices and Data in Distributed Industrial Applications
In this white paper, Moxa examines the unique security challenges posed by widely distributed computing solutions that put edge devices into residential homes and public spaces. When considering computers for smart grid, surveillance, and ITS solutions, system integrators must also consider how to lock down the hardware and software to protect the devices from being subverted by hostile exploits. End users and system integrators alike will find that the Trusted Computing Platforms figures strongly in the solution, and when combined with secure kernel authentication and a variety of other software and hardware features produces a powerful, versatile computing solution with a wide range of applications………more
