What is IoT Security?
IoT security refers to the protection methods used to secure internet-connected devices. The term IoT is incredibly broad and as technology continues to evolve, the term has only broadened. From drinking water supplies, energy monitoring systems to ATM's, almost every technological device can communicate with the mobile internet or other devices to some degree. IoT security is the family of techniques, strategies and tools used to prevent IoT devices from being compromised.
Advantage of a fixed IP address on an IoT simcard?
Internet connections facilitate information exchange. To establish a connection, the sender and receiver need an IP address. The advantage of an IoT simcard with a fixed IP address is the support for 2-way communication (bidirectional data traffic). The IP address (a fixed IPv4 address) is reserved for the simcard and never changes. Every IoT simcard has a fixed IP address, making the device remotely accessible through the cloud. Communication is possible on all ports.
What is an IoT VPN?
You cannot communicate directly to an IoT simcard without a VPN. A VPN adds the IoT simcard to its own private network (closed internet environment). This creates a secure VPN tunnel between the cloud and the IoT simcard and an IoT device can be reached remotely, as if it were within your local network. The VPN controls all layers of security. No additional software needs to be installed on your IoT device. The VPN secures and automatically authenticates all data traffic. Only IoT simcards configured within their own private network can access your cloud.
Apply IMEI lock?
When configuring IoT devices, Thingsdata customers have the option to configure an IMEI lock. An IMEI number is a unique 15-digit serial number that is linked to each IoT device. The IMEI number is assigned to mobile devices by a manufacturer to identify them on a mobile network. The IMEI lock option allows you to lock the use of an IoT simcard on an IoT device. Even if an attacker has gained access to your IoT device, there is no possibility to abuse your IoT simcard by deploying it in another device.
