To prevent sensitive data from being compromised, security is of paramount importance in organizations, which are typically warehouses of their own as well as clients’ data. The security issue becomes more prominent when an organization employs Internet of Things to connect its devices, and those devices control or interact with large data centers. According to a Cognizant report, IoT is expected to account for 28.1 billion devices by 2020*.And spending on IoT security is expected to reach $547 million in 2018 – double of what it was back in 2015**
There’s just too much risk and perhaps a good number of hackers lurking around, from what top research organizations predict. For example, according to Gartner, more than one-fourth of the total number of enterprise security breaches in 2020 will involve the Internet of Things in some way or the other.These numbers clearly spell out the need to prioritize security before IoT. A business goal has driven IoT plan which makes the most of connected devices while keeping data safe is how business folk should be approaching the problem. Here we have enlisted a few boxes that you should tick while tackling IoT security:
Manage all devices while on-boarding
Organisations that are huge can easily lose track of how many devices were added how soon unless there are a methodical device tracking and management system in place.
Secure all endpoints
Endpoints, that is, the devices can be as varied as the colors of the rainbow simply because each device was manufactured by a different manufacturer with different specifications. It is important to understand the nature of each endpoint and monitor its safety.
Secure the devices physically
Small and inexpensive hardware often comes with little to no physical security. If for example, devices are stolen or moved, they may pose a risk to security — and that’s something outside the purview of the IT guys.
Over and above securing the devices, adding an extra layer of security by encrypting data is a wise investment in your IT budget. Usually SSL or TLS is used to encrypt data, however, you also need to make sure that any wireless protocol that the system uses to communicate should have strong built-in encryption.
The authentication layer is used to identify the authenticity of an IoT device that is seeking access. Since authentication has to be automated (and not human initiated), this is done using RFID tags, certificates, MAC address and similar identifiers.
