In the era of the Internet of Things, using DDI to improve security

The era of the Internet of Things has arrived. Not only has family life become more intelligent, but there are also more and more IoT devices in enterprises. Currently, there is a total market of 25 billion US dollars in the world, and it is expected to reach 80 billion US dollars by 2025. However, in the eyes of corporate leaders, the term Internet of Things rarely appears, but it is indispensable in the actual operation of companies.

According to authoritative predictions, more and more companies will deploy IoT devices in the next decade, which will enable their businesses to run better.

IoT connects everything

However, the Internet of Things has brought new challenges to enterprise network administrators. Especially in terms of managing and protecting a larger number of devices, the influx of a large number of new devices has made the administrator's work more complicated. Although network operation and maintenance personnel have worked hard, the increase in IoT devices has doubled their workload. Using DDI (abbreviation for DNS, DHCP, IP address) can help operation and maintenance personnel better manage and protect IoT devices.

The Internet of Things is growing rapidly

It is very important to manage the IP addresses of the enterprise's local network. The IP addresses of hundreds of devices need to be allocated by the network administrator and the specific information needs to be understood. As IPv4 addresses are exhausted, enterprises are migrating to IPv6, which increases the complexity of management. Using IPAM can improve network management efficiency. IPAM provides detailed information about the status of devices. It is a basic component of the Internet of Things and can help operation and maintenance personnel view all local connections.

No matter what device wants to join the enterprise network, it must issue a DHCP request. DHCP can help operation and maintenance personnel identify devices and track device activities. The DDI solution maps IP addresses to MAC addresses and operating systems, and network administrators can manage devices based on device usage and prohibit illegal devices from joining the network. For example, if someone hijacks an IoT device and tries to use the address for prohibited behavior, the DDI solution can kick it out of the network.

The influx of IoT devices

In terms of security, operators can monitor DNS requests from each connected device and be able to view malicious activities and data leakage activities through DNS to protect corporate privacy. In addition, the solution can monitor the communication between botnets and servers and block the transmission of valuable information.
