How IIoT works and is it secure ?

 

How does IIoT work?


IIoT is a network of intelligent devices connected to form systems that monitor, collect, exchange and analyze data. Each industrial IoT ecosystem consists:

  • Connected devices which can communicate, sense and store information about there own working system.
  • public and/or private data communications infrastructure;
  • analytics and applications that gives business related information from raw data;
  • storage for the data that is generated by the IIoT devices.

    What are the risks and challenges of IIoT?

    The biggest risks associated with IIoT use pertain to security. It's relatively common for IIoT devices to continue using default passwords, even after they have been placed into production. Similarly, many IIoT devices transmit data as clear text. These conditions would make it relatively easy for an attacker to intercept the data coming from an IIoT device. Similarly, an attacker could take over an insecure IIoT device and use it as a platform for launching an attack against other network resources.

    Security is a challenge for those who are responsible for an organization's IIoT devices. As an organization adopts more and more IIoT devices, it will become important to adopt an effective device management. More specifically, organizations must be able to positively identify IIoT devices to prevent the use of rogue devices. Establishing a means of identifying each individual device is also crucial for tasks such as replacing a failed device or performing a device refresh.

    Patch management presents another big challenge regarding IIoT devices. It's becoming increasingly common for device manufacturers to issue periodic firmware updates. Organizations must have an efficient means of checking devices to see if they have the latest firmware installed and deploying new firmware if necessary. Additionally, such a tool must adhere to the organization's established maintenance schedule so as to not disrupt operations.

Following are the areas where IIoT improved industry production :  Production Now a days production sectors use IIoT technology the most. IIOT enabled smart machines, can monitor itself and anticipate possible production hurdles. This results in less downtime and improved efficiency. Supply Chain Keeping up production numbers is needed, smooth delivery across the supply chain is also important . With IIoT, orders can automatically replenish stocks when needed.     source : https://www.youtube.com/watch?v=JF7TfjbjdRo&t=1s This reduces waste, maintains stock numbers, and insures the correct amount of raw materials are always available. With the automation of supply chains and ordering, employees can focus on more complex areas of functioning. Building Management Building management problems can be handled with IIoT technology. Sensor-driven climate control removes all the uncertainty related to managing a building’s climate and takes all needed factors into consideration for example

  IIOT -   Industrial Internet of things   I ndustrial internet of things  ( IIoT ) is referred to interconnected devices like sensors, instruments, and other smart devices networked together with computers, industrial applications, including manufacturing and energy management. Use of IIOT allows data collection, exchange, and analysis and facilitates improvements or progress in productivity and efficiency as well as other economic benefits of a particular industry. Basically IIOT is a part of industry 4.0 evolution .   “machines, computers and people enabling intelligent industrial operations using advanced data analytics for transformational business outcomes”  Still not getting ?      watch this -->             source : https://www.youtube.com/watch?v=9ao4FEaDGhQ
