Securing Edge Devices and Data in Distributed Industrial Applications

 

Securing Edge Devices and Data in Distributed Computing Application White PaperIn 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

Building the Industrial Cloud:The Immediate Future of M2M Technology

 

Building the Industrial Cloud:The Immediate Future of M2M TechnologyIn 2013, substantial steps towards building the Internet of Things at last began to materialize. In this white paper, Moxa examines the sorts of technology industrial networks will be relying on as they begin to build and deploy machine-to-machine networks. Software automations, hardware optimizations, and integrated platforms that fully exploit the convergence of these two main branches of system design are examined closely, to give IA and IT engineers a better idea of what challenges and obstacles they should be preparing for at the dawn of this new technological epoch........more
