There’s a mostly invisible but integral software that keeps your devices moving, called firmware, and it’s often overlooked as a part of your business’ cybersecurity strategy. The following article will describe why keeping your firmware up to date is vital for securing your business.
What is Firmware?
Before we begin exploring the significance of firmware updates, it’s important to first understand what firmware is and how it contributes to the functionality of devices. Firmware is a unique software type embedded within the hardware of your device, and unlike regular software that runs from the operating system, firmware controls the device’s hardware components
It acts as a median between the device’s hardware and software, allowing them to work together. It’s found in all kind of devices, including (but certainly not limited to) routers, printers, cameras, and Internet of Things (IoT) devices.
Why is it Important to Patch Firmware?
There are a variety of reasons why keeping firmware up to date is crucial, such as:
- Security Vulnerabilities – Over a device’s lifetime, security vulnerabilities are exposed in current firmware that can be easily exploited by cybercriminals. Firmware updates frequently include patches to address these known vulnerabilities, which protects your devices from unauthorized access and data leaks.
- Enhanced Performance – Updates like these not only address critical security issues, but also include general improvements to overall performance and stability. This can lead to better, more efficient productivity, and an extended lifespan on your hardware.
- Compatibility – As technology continues to evolve, so does the software and apps that work on your device. Firmware updates ensures that your hardware remains compatible with the software you wish to use, diminishing the risk of compatibility issues that slow your operations.
- Feature Enhancements – Manufacturers frequently release firmware updates that introduce new features and enhance existing ones. Once you’re up to date, you can take advantage of the latest capabilities, which provides your business with a competitive edge.
What’s Good Protocol for Installing Firmware Updates?
While firmware updates are certainly essential, an improper installation can lead to issues down the line, even device malfunctions. Here are some good practices for firmware updates:
- Regular Monitoring – It’s important to stay informed about firmware updates for your devices. Most manufacturers will provide notes about the changes and improvements in an update. Make sure to check for updates and prioritize those addressing security vulnerabilities.
- Back Up Before Updating – Before going through with a firmware update, you should back up critical data. While very unlikely, there is a slight risk that the update process could have unforeseen issues such as data loss.
- Follow Manufacturer Instructions – Specific instructions for updating firmware may be released by each device manufacturer. You should always follow the recommended procedures outlined in the user manual or on the manufacturer’s website.
- Schedule Downtime – Conduct firmware updates during non-business hours in order to not cause disruption to your operations. If this update requires reboots, make sure it’s during a time that has the least impact to your business.
- Test Updates Before Deployment – You should consider testing the firmware update on a noncritical device first. That way, you have an opportunity to identify and address a potential issue before deploying the update elsewhere.
By understanding the important role that firmware plays, making sure these updates are timely, and using the best practices for installation, you can make sure that your operation remains secure and operates at peak efficiency. Keeping your firmware updated isn’t just a precautionary measure, it’s a proactive one, that safeguards your business against several constantly evolving threats.
