Cybersecurity versus IoT security and cyber physical systems
IoT security is not traditional cybersecurity, but a fusion of cybersecurity with 
other engineering disciplines.Digital control of physical processes over networks 
makes the IoT unique in that the security equation is not limited to basic information 
assurance principles of confidentiality, integrity, non-repudiation, and so on, 
but also that of physical resources and machines that originate and receive that 
information in the physical world.In other words, a large element of what distinguishes the IoT 
from cybersecurity is what many industry practitioners today refer to as cyber physical systems.Cybersecurity, if you like that term at all, generally does not 
address the physical and security aspects of the hardware device or the physical 
world interactions it can have.It addresses much more than mere data, servers, 
network infrastructure, and information security.Rather, it includes the direct or 
distributed monitoring and/or control of the state of physical systems connected 
over the Internet.
