February 1, 2025 One of the most significant technological developments in recent years has been the steady growth of 5G cellular networks. While technologies like AI and self-driving cars have become hotter conversation topics, 5G is one of the essential underlying technologies pushing those innovations forward. As this network continues to evolve, safeguarding 5G becomes critical to ensure its reliability, security, and ability to support the infrastructure powering these transformative advancements.
Between 2022 and 2024, the number of 5G mobile subscriptions worldwide more than doubled, from under 1 billion to 2.1 billion. This growth is paving the way for a major uptick in global digital connectivity and data use, thanks to the superior speed and bandwidth that 5G provides. The growth of 5G also coincides with the ever-evolving Internet of Things (IoT).
Along with exciting opportunities, 5G presents new cybersecurity concerns. For cybercriminals, more internet-connected devices and faster speeds mean more opportunities to exploit weaknesses and pull off larger-scale attacks.
Here’s a brief review of the evolving dynamic between 5G, the IoT, and cybersecurity.
How 5G Supports IoT Growth
Compared to 4G, 5G offers greater bandwidth, reduced latency (minimized transmission delays), and faster download speeds. These advantages are essential for expanding useful applications of the IoT.
The IoT refers to “smart objects” with sensors, network connectivity, and software that enable the collection and sharing of data. The IoT is strongly associated with “smart home” objects and systems, such as:
- Security systems
- Thermostats
- Lighting
- Appliances
Other IoT uses include connected vehicles, wearable tech, robotics, and virtual reality tools.
Many IoT objects, such as some smart appliances, can operate without an internet connection. However, in general, a high-performing connection is a key requirement for the IoT. For example, an internet-connected car relies on a fast connection to access real-time traffic data. Or, a smart security system may require significant bandwidth to transmit an uninterrupted video stream. To support these demanding uses, the expansion of 5G networks is key.
5G, the IoT, and Cybersecurity: More Connectivity, Greater Risks
The spread of 5G is exciting for everyone who employs digital tech, and that includes cybercriminals. For hackers and other bad actors, 5G presents opportunities to develop faster, stronger attacks.
5G advantages for cybercriminals include:
- Faster network speeds enable fast-moving attacks
- Greater bandwidth allows for the theft of larger amounts of data
- Larger networks make it possible to target more end-users in a single attack
In an increasingly digital, connected world, some of the most alarming cybersecurity areas involve systems of critical societal importance, such as aviation control and voting machine networks. However, there are also concerns regarding the personal daily use of IoT objects.
Compared to computers, phones, and traditional networks, IoT devices lack robust built-in security. Oftentimes, these devices are internet-connected but lack the processing power necessary to employ security measures such as virus scanners, firewalls, or encryption. As a result, individuals and organizations that embrace the IoT may be significantly increasing their cybersecurity vulnerability.
For hackers, any connected device represents a potential opportunity. Well-known attacks include accessing a security camera to spy on its owner, or hacking a Wi-Fi network to gain access to devices. Other emerging attack methods involve using smart TVs, online gaming systems, and even smart appliances as gateways for data theft.
Protecting 5G Networks Against Evolving Security Threats
The growth of 5G and the development of the IoT bring significant new cybersecurity challenges. Fortunately, although certain connected devices present new security risks, 5G itself offers key security advantages over older cellular networks.
One of the main security advantages of 5G is stronger encryption protocols. 5G uses 256-bit cryptographic algorithms to help safely move data across networks. Generally speaking, 5G encrypts more data and thus leaves less data vulnerable to hacking.
While 5G offers security advantages, 5G networks also face an evolving landscape of cybersecurity threats. Thus, safeguarding 5G networks is a major concern for groups like regulators, telecommunication companies, and cybersecurity firms.
While most cybersecurity responsibilities fall on the eventual users and managers of networks, telecom engineering teams like KMB Design Group also play a pivotal role. Telecom engineers incorporate the strongest possible safety protocols during project design. They also help coordinate efforts across stakeholder groups and maintain diligent threat detection throughout the project cycle.
