While the capabilities 5G introduces create many exciting opportunities, it also brings several security concerns people should know about. That said, individuals and organizations employing the necessary cybersecurity measures can effectively protect themselves from threat actors. Learn why cellular network protection is essential now, with 5G becoming more widespread.
Are 5G Networks Secure?
5G networks are secure, but as with older generations, taking precautions to enhance one’s network security is still necessary. It offers greater safety over older networks such as 4G, but relying on the protocol updates alone is not enough.
One way to look at it is that although the network can be highly secure, people must incorporate the necessary preventative procedures to make that a reality. To do this, businesses and families need to implement solutions to the threats plaguing the network.
5G Security Risks
With preventative steps, users are at a lower risk of experiencing cyberattacks. In addition, cellular network protection is essential because of the several security concerns 5G faces. Here are five security threats to 5G networks.
1. Increased Threat Landscape
5G is becoming more readily available and with that comes more devices connected to the internet. Statista estimates that by 2030, there will be 29.42 billion devices connected to the internet. That’s almost doubling the connected users now — 15.14 billion.
The increase of Internet of Things (IoT) devices brings a larger threat landscape. In other words, more devices equal more potential vulnerabilities for malicious actors to exploit. The truth is many of these systems lack the security to fend off threats. As 5G becomes more readily available, this requires further attention to make the network and the devices connected to it more secure.
2. Location Tracking
Another concern 5G creates is the possibility of location tracking. The problem is 5G has a much smaller coverage area than its predecessor. This is because 4G uses a single cellular tower to broadcast the signal and can better pass through walls than 5G.
On the other hand, 5G relies on smaller base stations and antennas whose locations are spread out. If a threat actor knows which cell tower someone utilizes, they can use it to pinpoint that individual’s location.
3. Supply Chain Threats
With 5G, there are also supply chain risks that manifest themselves in two ways. It uses much more software than older generations, and the number of vendors and suppliers for this new infrastructure is currently not high. These components can make the network more vulnerable to misuse.
For example, a few countries have banned the use of 5G infrastructure sold by Chinese vendors. The reason for these actions is these countries are concerned the equipment the vendors are selling has been exploited in some way.
4. DDoS Attacks
5G technology relies on software-defined networking (SDN) to operate. SDN uses software controllers and application programming interfaces to talk with hardware infrastructure to regulate the traffic on a network.
While this adds many benefits, it does create the possibility of threats such as Distributed Denial of Service (DDoS) attacks and other internet protocol problems. DDoS attacks are when a malicious actor disrupts the flow of traffic or service, and overwhelms the infrastructure.
5. Increased New Network Vulnerabilities
The software and systems 5G utilizes can create vulnerabilities for threat actors to misuse. These could include exploiting network slicing and SDN. Thus, it’s essential to monitor current threats and new potential vulnerabilities to implement solutions that protect the network adequately.
3 Ways to Enhance 5G Network Security
Considering all the threats currently facing 5G, here are three ways to enhance its network security.
Frequent Threat Assessments
There are many new and old threats 5G networks and their users are up against. For example, these could include DDoS attacks, Voice over Internet Protocol robocalls, highjacking of a network and many more. Therefore, monitoring technology for vulnerabilities cybercriminals could exploit, using a spam-blocking app and refreshing knowledge on cybersecurity best practices are vital.
The Power of AI and ML
Artificial intelligence (AI) and machine learning (ML) technology can be vital in securing 5G networks. With the threat landscape increasing, these technologies can learn, adapt and adequately protect the network from the modern dangers it will face.
Equip IoT Devices With Network Security
One great way to make 5G more secure is to address the issue with IoT devices. If one of them is compromised, it acts as an entry point the cybercriminals utilize to gain access to the network. These devices need to come equipped with built-in security that can effectively protect against online threats.
Adopt Cybersecurity Best Practices For Peace of Mind
With the several security concerns surrounding 5G networks, companies and individuals should adopt cybersecurity best practices to mitigate these risks effectively. These could include utilizing anti-virus software, using strong passwords and changing them frequently, implementing multi-factor authentication, keeping devices updated with the latest firmware, and using a VPN to connect to the internet. People incorporating these procedures can have peace of mind knowing their network and devices are well protected.
