As 5G technology continues to be rolled out worldwide—providing latency of a mere 1 millisecond—it is critical that information security professionals become familiar with 5G system architecture and security architecture, as well as the risks that come with implementing new cellular technologies. ISACA’s new white paper, 5G Security: Addressing Risk and Threats of Mobile Network Technologies, explores these topics, and compares 5G technology with 4G and previous generation cellular technologies.

As with any new disruptive innovation, we must strive to strike a balance between risk and reward. While it’s exciting to ponder the possibilities of a world powered by 5G and an constellation of connected things, we must first establish a secure foundation to support these innovations. A software-based, Zero Trust security framework represents our best chance at securing the Edge from the connected things of tomorrow.

The Cybersecurity and Infrastructure Security Agency (CISA) released its strategy to ensure the security and resilience of fifth generation (5G) technology in the U.S.

The year 2020 has served up some unprecedented challenges for the human race in every aspect, with wireless connectivity more important than ever. Particularly as millions continue to work and learn remotely, our connected world of devices, vehicles, homes and cities is expanding exponentially. According to a report from GSMA and ABI Research, the number of mobile subscriptions worldwide had already reached 8.1 billion by 2017 at an annual growth rate of 5.4 percent. It’s now predicted that by 2025 the number will increase to 9.8 billion, with 3G and 4G representing 51 percent of total subscriptions and 91 percent of the total traffic generated, while 5G subscriptions are expected to exceed 849 million.

The Trump administration has enacted several measures to protect U.S. national security, citizens’ privacy, and the integrity of  5G infrastructure from "Beijing’s malign influence," announced US Secretary of State Michael R. Pompeo. 

There is a trade-off between technology innovation and security. The adoption of emerging technologies like 5G will fuel the proliferation of Internet of Things (IoT) which are often built with basic security controls, creating a larger attack surface. At the same time, reliance on data means that data breaches can cause greater damage.

The pace of change within communications networks is happening at speeds not seen since the shift from circuit-switched networks to IP began a couple of decades ago.
