Answers to questions about IoT gateways (3)

21. How to enable communication or network security in the IoT gateway?
Channel-based communication using sub-channels (such as data channels, control channels, and management channels) can achieve secure communication. For example, security policy management and event monitoring messages need to be isolated at each communication level.
State-based system management is the most important method to protect system security. State analysis enables the system to react to unauthorized access requests.
Classification of unauthorized devices and applications used in conjunction with the system.
Geofence of the device for unauthorized movement analysis.
When the gateway receives a large number of messages, it may become overwhelmed in a form of "distributed denial of service" or DDoS attacks. Anti-jamming techniques can be used to resolve some forms of these attacks.
22. What is the blockchain security in the IoT gateway?
Because this technology uses "micro-ledgers" as evidence of peer-to-peer communication, it can be used for identity verification in IoT networks. The blockchain can record the communication history of two IoT gateways or devices. Once an action (or "transaction") is stored in the micro-account, it cannot be changed later. Although certificate-based encryption technology can be forged, blockchain has the advantage of being distributed.
23 Why are gateways important in any industrial IoT solution?
The biggest challenge of industrial IoT solutions is to collect data from traditional equipment and digitize it according to technological trends. The gateway connection with traditional equipment enables secure data processing and real-time analysis.
24. How does the IoT gateway mesh network add value in Industry 4.0?
Consider a specific industry sector, which has many gateways operating in various parts due to many smart devices and machines. All these gateways are connected to each other by forming a mesh network and realize peer-to-peer communication. The nearby gateways or gateways related to geographic location can be pre-configured as gateway clusters that can solve IT/OT convergence problems.
Distributed edge analysis is enabled for this cluster. Distributed edge nodes allow data processing at the edge before transmitting the data to the cloud. This reduces waiting time. The edge-filtered data can be sent directly to the fog node or cloud for post-event processing. In addition, a single cluster creates fog nodes, and the combination of fog nodes allows distributed fog computing. It has the advantage of fast real-time data analysis in any large-scale industrial field, thus shortening the fault response time.
25. Why does the smart grid need an IoT gateway?
The smart grid includes both users and utilities. At both levels, there are gateways-consumers (AMI) and utilities (substations). At the AMI level, the gateway allows distributed edge computing and forms fog computing nodes at the substation level. When these gateways are clustered, it allows utility companies to develop distributed fog computing networks. Gateway clusters also support communication between gateways, thereby providing the advantages of horizontal and vertical expansion. For example: if a gateway associated with a grid substation fails due to overload or any other failure, it can transfer the running application container to another substation gateway. This can reduce system failures. The fault identification and solution can be completed in the shortest time.
It can perform predictive maintenance on the system. It sends notifications to the utility company to inform the system of failures that require rapid response. The gateway achieves interoperability, provides a wide range of protocols, and ensures connectivity with most grid components.
26. How to protect the security of IoT gateway from network theft?
The most common types of attacks targeted are IP addresses, fully qualified domain names (FQDN) and malicious URLs. There are many frameworks that can identify and mitigate cyber threats, including Collective Intelligence Framework (CIF), Trusted Index Information Automatic Exchange (TAXII) and Structured Threat Information Expression (STIX). Such a technical framework continuously analyzes data and creates a message chain. For example, in the STIX framework, whenever a user requests specific data, the system will provide information about cyber risks, threats, recommended measures, and other information. In order to establish a chain of trust, it is important for IoT devices to share threats and other related information with nearby devices on the same network.
27. What is the basic checklist to follow before implementing an IoT gateway solution?
How many devices do you want to manage?
What is the distance between the gateway and the device?
Is the device connection protocol compatible with the gateway?
Is the data generated from the device large?
How many authentication levels are required for network security?
28. How does cloud computing use the IoT ecosystem?
The Internet of Things generates large amounts of data or big data. For enterprises, managing the flow and storage of these data is a tedious task. Cloud computing with different models and implementation platforms can help companies manage and analyze these data, thereby improving the overall efficiency and work efficiency of the IoT system.
29. What is the role of cloud computing in IoT solutions?
Cloud computing helps to store and analyze the data generated by the Internet of Things, so that enterprises can obtain the maximum benefits of the Internet of Things infrastructure. IoT solutions should connect and allow communication between things, people, and processes, and cloud computing plays a very important role in this collaboration to create high visibility.
With cloud computing, organizations do not need to deploy large amounts of hardware in IoT deployments, configure and manage networks and infrastructure. Cloud computing also enables companies to expand their infrastructure according to their needs without having to set up additional hardware and infrastructure. This not only helps speed up the development process, but also reduces development costs. Enterprises do not need to spend money to purchase and configure servers and other infrastructure, because they only pay for the resources they consume.
30. How does the equipment life cycle management platform work?
Enterprises create applications and software through cloud services (SaaS), which can connect devices and enable device registration, registration, remote device updates and remote device diagnosis in the shortest time, thereby reducing operation and support costs. The cloud introduces DevOps into the IoT ecosystem, which can help organizations remotely automate many processes. As more and more devices are connected together, data security, control and management challenges become critical. Cloud services enable remote device lifecycle management of the Internet of Things, which plays a key role in enabling a 360-degree view of the device infrastructure.
