What Is An IoT Gateway And How Do I Protect It?

Understand the operational functions of Gateway of a modern logistics company. You have a set of vehicles tracked using all IoT devices. You have warehouses with stock tracking and machine-operated production lines that manufacture products that are stored worldwide. Along the production line, IoT devices and sensors measure the output and performance of machines. You also have IoT devices and sensors that measure stock and tell the product line how fast to go based on this data. You also have IoT devices to send signals to drivers, telling them. That a pickup should take place and give signals only to cars that are close to the warehouse at that time. What Is An IoT Gateway And How Do I Protect It?

In this scenario many invisible events are taking place – Wi-Fi, Ethernet, Z-Wave, or ZigBee, devices communicating with cloud devices and sensors. And communicating with each other using different protocols on different networks. Clouds that communicate with complex systems. All of these are a bit heavy and the IoT Gateway solves many of the challenges of this older model.

What is an IoT Gateway Device?

The IoT Gateway device minimizes the communication gap between IoT devices, sensors, devices, systems, and the cloud. By connecting area and cloud organically, IoT gateway devices provide local processing and storage solutions. As well as the ability to automatically control the area based on data input via sensors.

Therefore it is an important access point for network connectivity both inside and outside your device ecosystem.

How does an IoT gateway device work?

As the capabilities and requirements of devices spread, it was often not possible to communicate them directly with the system. Some sensors and controllers do not support power-intensive protocols such as Wi-Fi or Bluetooth. Some devices collect data so. That it is massive and invaluable in raw form and all are connected to various public and private networks.

The IoT Gateway performs many important functions, from translating protocols to encrypting data, processing, managing, and filtering. If you override the IoT ecosystem. There is a gateway between the device and the sensor to communicate with the cloud. What Is An IoT Gateway And How Do I Protect It?

Reducing the gap between OT and IT Gateway

IoT gates help bridge the gap between operations and IT infrastructure in a business. They collect it by optimizing the performance of the system through operational data and processing it in real-time in the field or at the network edge.

As devices and sensors grow, so does the number of communications in a combination of public and private networks.

It is usually through the PKI infrastructure that each ‘subject’ conveys an identity, i.e. a pair of cryptographic keys (or digital certificates). Which allows communication to be encrypted.

If using you have a device. which handles all your device certificates, you will need a gateway (Certification Installation and Identification) to assist in mediating device on-boarding. More information on this is at the end of this post.

Real-time updates in the field

Suppose you notice damage on your devices or you notice. That one of the sensors is telling you that the warehouse is too hot. Without a gateway device, you would have to do manual solutions. Because your devices and sensors are too low in computing power to perform such tasks.

With the gateway, the data is sent to the gateway and the gateway is configured to send firmware updates to all devices (i.e. smart air vent dumpers). when the data is too hot for the warehouse.


When you have a low network connection speed or are charged with the amount of data going from the gateway to the cloud, you need to plan. Programa recommends using protocols such as COAP, MQTT, or UDP rather than TCP.

Connectivity issues

What happens when you do not have an internet connection? You can never be sure. That you will always have a smooth-running operation. You need to minimize it by running software without connectivity to your gateway. If the connection does not last long, it should use caching and queuing data.

Remote update

Your IoT gateway will inevitably require an over-the-air (OTA) update and therefore require a supported OS (such as Linux, etc.). This is all about What Is An IoT Gateway And How Do I Protect It?
