When looking for security solutions for your IoT device, you should start with a risk assessment. This includes analysing possible threats, vulnerabilities, the likelihood of them happening and evaluating the impact on your business in an event of a cyberattack. This risk analysis would allow you to decide the countermeasures you need to implement.
It's key to remember that IoT security is not a one-off thing, but a constantly moving target. The ever-evolving cyber landscape means that, the security of your device needs to be upgradable and updatable throughout the device lifecycle.
In this instalment of our IoT Masters series, Francis D'Souza, Head of Strategy for Analytics & IoT Solutions at Thales, discusses the three key elements you need to consider when securing the IoT:
- Secure the device
- Secure the cloud
- Secure the channel in-between the device and the cloud
Francis also discusses the two areas that are most overlooked when designing IoT solutions:
- Security by Design. Security in IoT cannot be retrofitted. It needs to be built in from the start or at least have the mechanism available to increase the layer of security later on.
- Security is a combination of technology and best practice. You need to make sure you combine the right technology with the best practices such as using encryption keys to make a solution secure.
Following all these principles to ensure the security of your device can seem baffling. Watch these video series for a step by step guide from Francis D'Souza on how to successfully implement IoT security into your IoT deployments:
