Security Issues in 5G Networks

The rollout of AT&T and Verizon 5G NETWORKS is in progress. Several cities are being turned up for 5G, and there are many more in the planning stages.

People are anxiously waiting for 5G and are excited about how it will take network speed to another level.  5G promises much higher speed and greater reliability. 5G will change the way network devices communicate as it will deliver significant advances in the technology sector. But as with any new technology rollout, there are severe security implications that need to be considered and addressed.

Network security

One of the significant issues that must be addressed is network security. A study conducted by scientists from ETH Zurich, the University of Lorraine/INRIA, and the University of Dundee, indicated that interceptions in 5G communications are easy. The study implies that hackers will not have difficulties in hacking the communication that is using 5G. This study contradicts information that describes how 5G networks are protected against International Mobile Subscriber Identity (IMSI) catchers.

Data theft

Data is vulnerable to theft on 5G networks. The scientists argue that there is a lack of precision and security goals are under-specified.  There is a need to increase protection in the 5G network to enable it to protect data from loss or being intercepted by hackers.

Serious 5G Vulnerabilities must be dealt with

Researchers from different universities have discovered that there are severe vulnerabilities in 5G.  There is a broader attack surface related to accelerating the adoption of virtualized distributed network infrastructures and the use of containerized workloads. This increased attack surface makes 5G networks an excellent playground for hackers. As a result of the distributed systems and containerized environment, it is difficult to ensure that systems and applications remain protected against newly identified vulnerabilities.

Denial of service attack

With 5G, you will be able to have many different types of connected devices in your home and can check on them remotely with the use of applications. This introduces new challenges and new opportunities for hackers to exploit vulnerabilities. Imagine that a malicious neighbor gains control of your home devices while you are away on vacation. You may come home to a warm refrigerator, a wet house, and destroyed electronics!

In conclusion, this 5G network is a significant advancement, but it also has serious security challenges. Existing 4G security challenges are amplified with the new architecture of 5G. We expect that 5G network exploits will be in the news as the 5G rollout continues.
