There are billions of connected devices worldwide and the number is increasing. International Data Corporation (IDC) has predicted that by 2025 there will be around 41.6 billion connected devices. Many of these connected devices are powered by a small chip known as MCU (Micro Controller Unit). 

Like a human brain, MCU acts as a brain of the device that stores the data, hosting the compute, and an operating system on the device. Also, to safeguard these microcontrollers from cyber-attacks you should integrate the device, software, and the cloud in one secure solution this is where we require an end-to-end IoT device security platform like Azure Sphere.

Securing Your IoT Ecosystem With Azure Sphere

Microsoft has expertise in hardware, software, and cloud technology to provide secure connectivity from the silicon to the Azure Sphere OS to the Cloud. It brings together Azure Certified MCUs, the in-depth defense of the Azure Sphere OS and over the air updates from the Azure Sphere Security Service that protect your devices from evolving threats.

cloud security

With Azure Sphere, you can securely develop the IoT solutions and connect to the cloud. Moreover, Azure Sphere lets you build your solutions on any cloud platform, be it private or public. 

It doesn't require any specialized personnel to connect your devices securely as it uses the OTA (Over The Air) updates to keep your connected device up to date and secure. Microsoft has considered 7 different properties to safeguard IoT devices. Let's look at them in detail.

7 Properties of Azure Sphere to Safeguard the IoT Devices

Lately, security threats against connected devices have been increasing, which has been causing companies to adopt security measures like Azure Sphere to safeguard their IoT Devices from attacks like a MIRAE botnet attack-taking complete command and control of servers, Xbash attack-attacking weak passwords, and unpatched vulnerabilities. Muhstik attack — botnet self-installs and infects Linux servers.

Newer threats are evolving every day and hence it becomes essential to secure your IoT devices. Many companies are struggling to protect their IoT devices. With years of experience and research, Microsoft has found these properties for end-to-end securing of your IoT devices. These specifications clearly outline the needs of an IoT device with numerous protective layers to improve security.

IoT security

Hardware Root of Trust

Single-purpose hardware, so that it is more secure and hard for an attacker to hack the device. It can detect when it is likely to be attacked and how to mitigate the attacks.

Defense in Depth

The reasons for lack in security arises due to having only a single layer of defense, a single error in design sometimes can lead to a security compromise. We cannot anticipate the threats hence having multiple security measures is required. Also, other reasons for lack of insecurity is the load it creates on the processor and the costs.

Small Trusted Computing Base

A trusted computing base (TCB) comprises of both the software and hardware used to build a stable operating environment and it ensures the security of the system. It should be as small as possible, as less code = fewer bugs. This helps in reducing the attacks.

Dynamic Compartments 

The compartments are protected by hardware boundaries to prevent any breach from the software compartment. It provides additional protection within the software and hardware stack to create a layer of defense. For example, you can use operating systems processes or independent virtual machines as compartments.

Certificate-Based Authentication 

You do not need a password protected device, passwords are problematic and prone to hacks or can be stolen. Certificates cannot be forged or stolen. Also, it can be tracked if the device is compromised or not and necessary action can be taken.

Failure Reporting

An automated failure reporting would send the information when the device is hacked or attacks being attempted on it. Also, it will detect the flaws in the software.

Renewable Security

As more security threats are discovered, the software is constantly updated through new versions. An update provided to the cloud, which the software would apply to keep the system updated to keep the device from becoming vulnerable to being attacked.

These seven properties can be used by any organization to make sure they meet their security measures. Meeting all seven properties can be challenging, you can leverage Azure Sphere for that purpose. Azure Sphere sum up all these properties for securing your IoT device and keeps you ahead for your secured IoT developments

With this end-to-end security, companies will be able to move from smaller IoT developments to large-scale developments. Hence, for addressing these security threats, you will able to focus on bigger IoT goals that benefit and improves the productivity of your business.
