Automating Firmware Updates for IoT Devices

The lack of efficient tools to manage IoT device deployments has become a liability for modern organizations. This shortcoming is particularly evident in the area of firmware updates.

To better understand organizations’ IoT-related challenges, we surveyed customers managing large fleets of devices across various industries. When asked to rank their main operational challenges, the majority named ongoing maintenance of firmware upgrades as their most critical challenge.

In the absence of automated tools, most firmware updates are performed manually (if at all). Manual updates are costly and time-consuming, extremely error-prone due to interoperability issues, and lack proper validation and supervision. The result is that organizations rarely upgrade firmware versions – even those with known vulnerabilities – exposing their devices to potential cyber attacks or operational failures.

 

The Power of Automation

Manual firmware updates are a non-starter for maintaining IoT deployments – often spanning several geographically distributed sites. Moreover, unlike other types of maintenance activities, firmware upgrades require physical access to the device itself. When maintaining large-scale IoT deployments (thousands of devices and more), the need for automation becomes even more critical.

From a security standpoint, using an old firmware version with published vulnerabilities is an open door for cyber attackers. After exploiting the vulnerability to gain a foothold in the IoT network, attackers can potentially move laterally within the network, jeopardizing the organization’s most valuable assets and data.

Not performing timely firmware upgrades can also exact a heavy operational price. For example, let’s say your Physical Security manager notices that CPU utilization has reached 100% on dozens of devices. If the root cause isn’t detected and corrected quickly, it’s only a matter of time before those devices crash. And even before they crash, they may not be operating properly.

How You Benefit from Automated Device Firmware Upgrade

Using automated firmware upgrades, organizations can avoid the issues mentioned above. IoT teams can stop worrying about whether firmware versions are frequently upgraded or whether vulnerable firmware is identified and patched.

Back to the previous example where your devices are running at 100% CPU. Root cause analysis discovers that other devices of the same model using a newer firmware version are operating normally. With a couple of clicks, the Physical Security manager can automatically update all relevant devices with the new firmware. Problem solved.

Automated firmware upgrades make the daily routine of maintenance teams much easier. Manual updates become a thing of the past, while end users can manage device operations quickly and efficiently (regardless of scale) with full process supervision and update validation. In addition, automated firmware upgrades ensure devices will always be protected from known issues that manufacturers have addressed in the latest version.

From a device management standpoint, automatically identifying vulnerable firmware versions helps organizations improve their compliance posture related to security and operations. In this way, automation smooths the way for IoT and IT teams to work in sync to secure organizational networks and assets.

Streamline IoT Device Maintenance and Improve Cyber Security Posture

By automating firmware upgrades across all devices, organizations can streamline operational efficiency and extend device lifecycle, while ensuring the security and availability of their business-critical IoT devices. Equally important, automation enables significant cost and time savings by eliminating manual updates.
