The challenges of IoT security
Welcome to the world of Internet of Things (IoT) and a glimpse into the future. The IoT is where the physical world merges with the digital world. Soon, we expect the world IoT population to outnumber the human population tenfold—perhaps as many as 80 billion connected devices by 2025.
As you witness the accelerating global and economic growth of IoT you are probably wondering how you and your business will connect and take part in the multi-trillion dollar opportunities that will be created by it.
It means different things to everyone—from a connected car to a smart lamppost, a wearable health monitor, or a robot on the assembly line of a factory floor. It might even be ‘connected dirt’—with swarms of small, solar-powered sensors on the fields of a farm.
No matter which way you do it, there’s a daunting task ahead: the acceleration of IoT, combined with the diversity of these devices, their different capabilities, and the many places and ways they can be deployed—make security a unique challenge.
What you need is a consistent way to establish and maintain security for all aspects of the IoT deployments you envision for the future of your business.
This is within your reach, by adopting a holistic, multi-layered approach to protect your IoT ecosystem, your other valuable assets they connect to, as well as the physical world they reside in.
Solutions for your Internet of Things security needs
Protect your IoT with a layered approach.
Every IoT ecosystem has its own distinct security needs. Even for a single client, seemingly similar IoT deployments may have different underlying designs. For example, a factory built today may have a radically different design from the one built just a few years ago. This means a combination of different solutions may be needed to help provide security for each of them.
A thorough security assessment of IoT is a multi-layered process. Every layer needs care and attention. Some endpoint devices are complex, with multiple ways to access the internal functions of the device. Others are simple, years behind smart phones with regard to security. Do you know your devices’ security capabilities?
Endpoints may connect with each other, to and through gateways, to other networks, on the Internet, and to the cloud. They may use connections that include wired, wireless, short-range, cellular, and satellite. What could potentially disrupt them from communicating?
To make your IoT deployment successful, data from your devices must be acquired, transported, processed, and consumed. How are you providing for trust and appropriate access to your vital data and applications?
Realize that some IoT ecosystems can vary wildly from a traditional IT environment. Industrial IoT deployments use operational technology which flips the script on the classic model for information security. Availability and integrity are the priority, while confidentiality isn’t typically a consideration. This requires specialized passive scanning tools to perform assessments. Slight disruption to manufacturing or utility processes turn into massive financial loss. An example of this is a factory that produces a pickup truck every minute—it cannot afford downtime. Life-sensitive devices will affect remediation and response plans. So for example, a connected healthcare device like an insulin pump—even if you think someone is accessing the data, you wouldn’t want to disable the device.
