IoT: Secure First, Then Connect
As various devices communicate in real time, we need to validate whether signals have been manipulated to ensure that the information is reliable. In other words, we must check the integrity of the devices. In addition, devices validate each other to check for proper function. Ensuring that they are not compromised or connected to by hackers for malicious purposes is a must and permission must be obtained to access each device while establishing a connection – secure the device first, then connect.
Device Communication Must Be Encrypted Communication
IoT gateways collect data from a given device and send it to a server. During this process, hackers can access data and invade the privacy of its users. They can give out commands for malicious purposes and manipulate the devices. Therefore, it is essential to encrypt communication and validate devices in order to protect the data and users.
Continued Security of the Server and Infrastructure
Even if we can securely collect data from devices, hackers can still attack the gateway and server networks storing the data. Therefore, we need to protect the servers and ensure the security of the entire infrastructure through the use of authentication and encryption keys.
According to Gartner, an information technology research and consulting firm, about 5.5 million new devices are connected every day and 21 billion devices will be connected by 2020. As the number of connected devices increases exponentially, it is important to manage certificates and keys used for the authentication of each device. We also must protect a large volume of data for security purposes as the number of devices grows dramatically.
