To realize the need and significance of security perspectives in manufacturing automation lets discusses Internet of Things (IoT) in smart manufacturing where the initial step is to recognize the sensors prerequisite into the machine parts from where real time analytics will get the data, for example, continuous temperature change from thermostat sensors or to quantify the speed of any moving item in a machine, connected sensors will be utilized , which will create the data for speed measurements, similarly assortment of sensors are accessible which can be utilized according to the necessities , second steps is to catch these data for the investigation use for that we require IoT gateway, then the third step is get the continuous data through a few popular software tools like Flume or Kafka then the fourth step is do the real time investigation to give real time visualization remotely which will be usually done on cloud thus, getting the software as a service on cloud is a great challenge for IT security suppliers , we really require a high security angles to spare our private data from the programmers separated from that in this paper necessities of security , security configuration in smart manufacturing and end to end protection of data has been talked about.
