Almost 20 years ago, the introduction of computer-driven automation brought fundamental change to the manufacturing industry. Today, with the advent of the Internet of Things (IoT), manufacturing is changing again. The traditional factory floor already accustomed to interconnected production means along a predefined hierarchy, with every asset working together to achieve efficient production at optimal costs. With SIM-enabled IoT, new “smart factories” are envisioning a hyper-connectivity that maintains constant data flows along every link of the value and supply chain to close information and inventory gaps, increase operational efficiency, and lower overall manufacturing costs. This new level of connectivity, backed by IoT and SIM technology, has led some to declare SIM IoT manufacturing as the fourth industrial revolution, or Industry 4.0.
Businesses have long become accustomed to utilizing security protocols such as firewalls and compliance engines to protect proprietary data on their computer networks. However, with the adoption of the Internet of Things (IoT), data now is regularly transferred across the internet from SIM-enabled devices to management platforms. Without protocols in place to protect IoT data transfers, sensitive operational information will be moved across the public and open internet, leaving it highly vulnerable to compromise from hacking, eavesdropping, or information leakage. To prevent these kinds of data compromise, IoT networks must employ security protocols that can extend their network across the internet to privately connect their devices. This type of security connection is called a virtual private network (VPN).
