For many industry experts and business observers in the tech fraternity connected device ecosystem widely referred as internet of things solutions poses some grave security threats and vulnerabilities that app developers and businesses have to deal with. Most of these people fear that connected devices with their easy accessibility and fluid interface pose bigger security threats just as big advantages. But as IOT is increasingly becoming indispensable, you need to build the network trustworthy instead of replacing it. The new challenge is to deliver trusted IOT device ecosystem. Here we are going to look deeper into the challenges and principles of trusted IOT device ecosystem.
Let us try to answer some of the most important questions concerning IOT device security.
- Secure Boot Approach As A Digital Signature
First of all, Secure Boot can help building a trusted platform which is the most preferred solution as far as IoT device security is considered. Let us see how Secure Boot works to ensure security.
Secure Boot is also referred as device tamper detection and it uses digital signatures allowing validation and authentication of device software as soon as the device is turned on. This prevents malicious software creating any performance issues.
Just the way a legal document is signed and checked, digital signature as a process does the same to ensure device level security. This improves device level software performance and output and users can easily trust the device in respect of output.
- Booting The Device Into A Secure State
This is often referred as a ground-up approach which provides a security layer to the device or app strengthening protection from malicious threats and glitches. As per this approach as soon as a device just takes a start from reset, the device enters into a non-vulnerable state free of tampering scopes. This is done mainly by code signing and it allows the device self testing processes to check authenticity and integrity of the device firmware.
Let us go a little deeper and see how this approach really works. When the device is powered on, the Root of Trust code gets into action from a secure location within the device. This code actually works to verify the actions of the code by the use of s signature. This verification process is carried out with a public key which comes packed with the device through the method of multiple certification.
Why the security measures are to be built inside IOT devices right from the beginning?
We no longer can afford to keep security measures outside of devices as number of connected devices are outpouring. With the connected reality and connected solutions taking over our world we need to equip devices with smart security measures that from within can guarantee smooth and glitch free performance. This is precisely why in built device protection and measures to keep vulnerabilities at bay are becoming so important these days.
Keeping this increasing focus on device level digital signature and security we can think further to make this even more equipped and fine tuned with customised security features and measures.
