What is 5G?

  • Published: Wednesday, Sept. 18, 2019

5G stands for fifth generation cellular wireless. 5G networks will have greater speed, lower latency and the ability to connect a lot more devices at once. In this post we will not discuss the ins and outs of how 5G is different from past generations or how it actually works. There are resources at the end of the article where you can read about that. Instead, we are going to examine the security implications associated with 5G.

Since 5G will support a lot of connected devices and increased bandwidth and this creates a new and widening threat landscape.

  • The Internet of Things (IoT) will be a major avenue for an attack.
  • Cyber attacks on automobiles will rise as the use of autonomous vehicles becomes more prevalent.
  • Smart homes will require stronger authentication methods through the use of biometrics or voice and facial recognition. Unauthorized access prevention will need to become more complex.
  • Elevated use of virtualization and the cloud will increase the attack surface.

Signal penetration limitations of 5G will cause devices to act as a relay for passing information along the network. The relaying of data between devices increases the risk of cyber attacks like Denial of Service or data interception.

While noting that most of us think of IoT as smart home devices the majority of IoT is about electrical grids, medical devices and public transportation among others. 5G creates new vulnerabilities through it’s connectivity that can present new security flaws.

5G network infrastructures will need to evolve with the new standard. A different security method may be needed for individual applications or IoT.
