6 strokes to crack the security dilemma of IoT product development

Internet of Things (IoT) technology has grown exponentially over the past few years, and new solutions are emerging and adopted at an unprecedented rate. According to the Gartner report, more than 4 billion IoT devices have been installed by the end of 2016, and this number will increase to 20 billion by 2020. In the IoT market, in the past year alone, the connected equipment spending in the enterprise exceeded $ 668 billion, and the impact and risks of the Internet of Things adoption have become apparent.

6 strokes to crack the security dilemma of IoT product development

Although still in its infancy, IoT seems to have won the title of poor security. After 16 years of DDoS attacks on DNS provider Dyn, security experts have begun to focus on how to better handle the growing access to insecure connected devices. Attacks like this are caused by suppliers rushing to meet the peak demand of smart devices. After the products are introduced to the market, although consumers are keen on IoT products, they are basically unaware of the security risks they pose.

The burden of protecting connected devices and the ability to repair them when they are exploited will fall entirely on product manufacturers and software developers. It is critical for organizations developing IoT technologies to ensure that their products do not pose a risk to the security or privacy of end users. The following methods that you must pay attention to can minimize user risk and improve security:

1

Physical security

The physical security of connected devices is critical. Integrating tamper-proof measures into device components should be the developer's first choice, ensuring that the device is not decoded. In addition, if the device is destroyed, it is necessary to ensure that device data related to the authentication code and account information is erased, preventing private data from being maliciously used. If the PII is stored on the device, the remote wipe function should be implemented.

2

Don't leave the back door

Building a device with a back door is now easy to implement for monitoring when needed. However, this practice can jeopardize the security of the end user. Manufacturers should ensure that no malicious code or backdoors are introduced and that the device's UDID is not copied, monitored, or captured. This will help ensure that the process is not captured or susceptible to monitoring, monitoring or illegal monitoring when the device is registered online.

3

Secure coding

IoT developers should implement secure coding practices and apply them to devices as part of the software build process. Focusing on QA and vulnerability identification/remediation as part of the development lifecycle will simplify security efforts while reducing risk.

4

Device authentication

Use a single device ID for proper and secure authentication, establishing a secure connection between the device itself and the backend control system and management console. If each device has its own unique identifier, the enterprise will know that the device communication is indeed what it claims to be. This requires separate device identification based on solutions such as PKI.

5

encryption

When using an IoT solution, organizations must encrypt traffic between the device and the back-end server. Ensuring that the command is encrypted and viewing the integrity of the command by signing or strong encoding is critical. Any sensitive user data collected by IoT devices should also be encrypted.

6

Simplify the update process

Simplify device upgrades to deploy error and security updates in an easy-to-manage manner. If the firmware is not properly configured from the start, its update can be tricky. Unfortunately, manufacturers sometimes build devices that do not have firmware update capabilities and choose to use write-once memory. Although this approach has been economically significant in the past few years – manufacturers see it as a more cost-effective way to integrate more easily and help them avoid overwriting or implementing different operating systems on their devices – but More important now is that they ensure a consistent flexible firmware deployment process, allowing developers to create new models while distributing security fixes across product lines.

IoT will soon infiltrate every corner of our lives. As more IoT security incidents occur, equipment manufacturers will face increasing pressure to focus on enhancing the safety of their products in the future. By following the steps above, connecting technology providers can ensure they remain competitive in the increasingly crowded IoT market, as device security will be a top priority for buyers.
