IoT security is often the main concern for organisations planning an IoT deployment. Security incidents can damage your brand and reputation, and cause significant financial loss.
But security for IoT deployments is particularly challenging. To succeed, you need to design security into your devices and systems from the start.
Part 1 of this series on IoT-enabled smart vending machines discussed the challenge of securing great connectivity for your deployment. Part 2 was about achieving business value from the data you collect.
And last – but certainly not least – we discuss how to address the challenge of IoT security.
IoT security challenges and risks
The characteristics of an IoT deployment make security particularly challenging:
- Hundreds or thousands of devices must be secured; one compromised device can infect the whole network
- Devices may be located in hard to reach locations, increasing the possibility of security gaps in the network
- Devices usually have minimal computing resources, making it harder to implement the usual security protections
Security breaches can lead to Denial of Service (DoS) attacks, unauthorised access to devices, data breaches, and malware or ransomware attacks.
Vending machines with Point of Sale (PoS) terminals have particular vulnerabilities. Hackers can steal credit card details to sell on the black market, or send malicious code to take control of the digital display.
IoT security issues
Common IoT security issues include:
- Software on the devices that is out-of-date or has known vulnerabilities
- Weak or default credentials on devices
- Credentials that need to be input manually
- Configuration settings, such as authentication and authorisation, that don’t follow best practice
- Lack of device monitoring and behaviour analysis
IoT security solutions
A best practice IoT security solution includes features such as:
- A unique authentication certificate for each device
- A zero-touch approach – no manual assignment of certificates or input of passwords or codes
- Automatic over-the-air (OTA) delivery of a certificate and security policy when a device is first deployed and when required to maintain security
- End-to-end encryption for data transfers
- Software updates pushed OTA to devices when required
- Centralised device monitoring and management, including:
- Prompt notification of potential security issues
- The ability to take action quickly and easily, such as isolating a compromised device
Your solution needs a scalable framework and architecture so that it keeps pace with the growth in your deployment.
If you’re using third parties for data storage and device management, you need to make sure they offer the security provision you require.
