Generally speaking, remote updating provides major advantages for IoT devices. It allows functionality improvements and security patches to be delivered seamlessly without requiring physical access to the device. However, potential compatibility issues and other risks need to be considered.
Why Remote Updating Matters for IoT Devices
Keeping IoT devices updated is critical for two main reasons:
Improved Security – Like any software, IoT systems contain vulnerabilities that can be exploited by hackers if left unpatched. Remote updates allow security issues to be quickly addressed even after deployment. This helps protect devices from compromise.
Enhanced Functionality – In addition to closing security holes, remote updates also enable new features and other enhancements to be added to IoT systems conveniently after purchase. This brings additional value to consumers.
Without remote updating capabilities, IoT devices would have to be manually reprogrammed or even replaced entirely to gain new functions or security fixes. This process would be extremely costly and time-consuming.
The Risks of Outdated IoT Devices
Failing to update IoT devices regularly comes with significant risks, including:
- Malware attacks – Unpatched vulnerabilities can allow malware like Mirai to infect devices. This malware can be used for DDoS attacks and more.
- Data compromise – Hackers can potentially access device data like video feeds, files, credentials and other sensitive information.
- Bricked devices – Severe bugs could render devices unusable if updates are ignored. This essentially bricks the device.
- Compliance issues – Neglected updates could result in non-compliance with regulations like HIPAA healthcare standards.
- Functionality loss – Bugs and glitches can build up over time, crippling device functionality if updates are not installed.
Only by promptly installing remote updates as they become available can these threats be avoided.
Manual Updating of IoT Devices
For IoT devices without automatic update capabilities, users must manually check for and install over-the-air updates. Here are the steps involved:
1. Check the Manufacturer Website
Most IoT device vendors will post update notifications and firmware download links on their support site when new versions are released. Check frequently for any available updates.
2. Download Update Files
Once an update is found, download the firmware or patch files to your computer. Make sure to get all required files as specified.
3. Connect Device for Updating
Follow manufacturer instructions to connect the IoT device to your computer, usually via USB cable. This allows the update to be transferred.
4. Install the Update
Use any update utility provided by the vendor to install the downloaded firmware on the connected device. Allow the update process to fully complete.
5. Test Device Functionality
When finished, test that the device is fully functional as expected. Report any issues to the manufacturer.
| Pros | Cons |
|---|---|
| User has full control | Time-consuming manual process |
| No reliance on internet connectivity | Easy to miss updates |
| Can troubleshoot issues | Risk of improper update installation |
While manual updating gives users more control, it can be tedious and error-prone. But for IoT devices unable to update remotely, it is still essential.
Automated IoT Device Updating Solutions
Many modern IoT products come with remote update automation features built-in. These solutions make getting updates far more convenient compared to manual methods. Here are some examples:
Cloud-Based Updating
Popular consumer IoT vendors like Amazon, Google and Apple offer cloud services to automatically deliver updates to connected devices.
With this approach, the IoT device periodically checks the cloud service for any new firmware versions the manufacturer has released. If one is found, it is automatically downloaded and installed on the device in the background.
For the user, no effort is required. The IoT ecosystem handles the process seamlessly. But an active WiFi connection is required.
IoT Mobile Apps
Some manufacturers provide mobile apps to remotely check and update their IoT products. For instance, apps for smart lightbulbs let users view available firmware versions and trigger updates with the tap of a button.
The apps connect to the devices locally via Bluetooth or through an internet cloud service. They make updating simple while adding mobile control. But an additional app installation is needed.
DIY Automatic Updating
For open-source and DIY IoT systems, developers can build their own automated update functionality using free toolkits like balena and Mender.io.
These tools add a management layer that handles tasks like firmware pushing, monitoring and rollbacks automatically based on defined settings. This streamlines updating for custom projects. But specialized programming knowledge is required.
Advantages of Automated IoT Updating
Automating the remote update process provides some major benefits:
- Easy and convenient – Updates happen in the background without user input needed.
- Constant protection – Devices always run the latest firmware version with vulnerabilities fixed.
- Wide accessibility – Mobile apps allow updating from anywhere with cell service.
- Time savings – No manual monitoring or installation time required.
- Reliable process – Automated systems are less prone to human error.
