5G Expansion Magnifies IoT Security Stakes

As societies further intertwine with the Internet of Things (IoT), critical infrastructure risks escalate due to potential vulnerabilities in millions of everyday connected devices like utility meters and traffic control systems. With the market for IoT in the U.S. predicted to reach $199 billion by 2024, the urgency to safeguard national infrastructure is more pressing than ever. The evolution of 5G technology has enhanced the functionality of IoT devices, embedding them deeper into essential services, but simultaneously increasing the exposure to cyber threats.

Amidst the growing concern, U.S. policymakers like Representatives Mike Gallagher and Raja Krishnamoorthi have raised their voices about the security challenges posed by IoT devices to the nation’s well-being. As 5G technology becomes woven into the nation’s fabric, from public utilities to vital industries, the security of the IoT is no longer a mere business concern but a matter of national interest.

Understanding the potential for IoT security lapses to disrupt essential services and trigger chaos, there is a nascent shift in treating IoT security as a key aspect of protecting national security. The communications between Congress members and several government departments underscore this evolving perspective.

IoT modules—key components responsible for data transmission within these devices—are identified as the Achilles’ heel of IoT security. Any exploitable weaknesses within these modules can undermine the integrity of the extensive systems to which they connect, turning devices into potential security timebombs.

Given the profusion of IoT devices and their updates—which are challenging and costly to validate comprehensively—the active role of federal regulators is significant in shaping a robust national defense against cyber threats. The conversation around supply chain reliability amplifies with revelations of significant penetration by Chinese entities, such as Quectel, in the U.S. market, thus prompting inquiries on how to tackle vulnerabilities linked to foreign suppliers.

The multi-faceted nature of the IoT security conundrum calls for a delicate approach, considering the severity of the threat and the ramifications of sweeping actions like outright bans. Further discussions and analyses are anticipated to unravel the complexities of ensuring IoT integrity in a connected, yet uncertain, digital landscape.

In summary, the expansion of 5G technology raises the stakes for IoT security as these devices become intertwined with national infrastructure. Policymakers recognize the gravity of the situation, and discussions are underway to ensure the security of the IoT ecosystem and protect against potential cyber threats.

FAQs about IoT Security and Its Impact on National Infrastructure

What is the Internet of Things (IoT)?
IoT refers to the network of physical objects (“things”) that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.

Why is IoT security a national concern?
As IoT devices are increasingly integrated into critical infrastructure systems such as utility networks and traffic control systems, their security becomes paramount to safeguard national infrastructure against disruptions and cyber threats.

What is the market prediction for IoT in the U.S.?
The market for IoT in the U.S. is predicted to reach $199 billion by 2024.

How does 5G technology influence IoT?
The evolution of 5G technology enhances the functionality of IoT devices by allowing faster and more reliable data transmission. However, it also increases the risk of exposure to cyber threats due to the expanded attack surface.

What actions are U.S. policymakers taking regarding IoT security?
U.S. policymakers, such as Representatives Mike Gallagher and Raja Krishnamoorthi, are actively discussing the security risks presented by IoT devices and considering ways to integrate IoT security into national security measures.

What are IoT modules, and why are they critical?
IoT modules are components responsible for data transmission within IoT devices. They are critical because any security weaknesses in these modules can compromise the entire network they are connected to.

What challenges do federal regulators face regarding IoT devices?
Regulators face challenges in validating the security of the multitude of IoT devices and their updates, which are often costly and complex. Furthermore, dealing with the implications of foreign suppliers in the supply chain adds another layer of complexity.

What concerns are there about foreign suppliers like Quectel?
The presence of significant penetration by Chinese entities such as Quectel in the U.S. IoT market raises questions about supply chain security and the management of vulnerabilities associated with foreign suppliers.

What strategies are being considered to secure IoT?
Strategies include treating IoT security as a national security concern, enhancing federal oversight, examining the reliability of the IoT supply chain, and facilitating discussions on how to approach vulnerabilities without dramatic actions like outright bans.


Critical Infrastructure: Physical and virtual systems and assets that are so vital to a country that their incapacity or destruction would have a significant impact on security, national economic security, national public health or safety, or any combination of those matters.
Cyber Threats: Malicious attempts to damage or disrupt a computer network or system.
5G Technology: The fifth generation of mobile network technology that provides faster speeds, lower latency, and increased connectivity for more devices.
National Security: A collective term for the defense and foreign relations of a country, protection of the interests of a country, and the safety of its citizens from external threats.
