NSA reduces security risks for 5G mobile devices | Jobs Reply

A working group assembled by the US National Security Agency (NSA) has issued a report outlining the cybersecurity threats related to 5G cell phone network slicing.

Network slicing allows operators to consolidate multiple network attributes or components, potentially across multiple operators, supporting specific applications or services for 5G users, the report explains. While efficient for service delivery, 5G network slicing casts a broad threat web that includes potential vulnerabilities in policies and standards, the supply chain, and more.

“Although network slicing is not unique to 5G, it is a critical component as 5G specifications call for network slicing as a fundamental component and therefore require network operators to adopt security practices that can mitigate threats such as those outlined in this document,” it says said in the report.

Potential threats include denial of service (DoS), man-in-the-middle (MitM) attacks and configuration attacks, he added.

The NSA, along with the Cybersecurity and Infrastructure Security Agency (CISA), brought together members of the public and private sectors to address the security concerns of 5G slicing. The resulting 5G network slicing cybersecurity report explores the role architecture will play in enabling emerging technologies, including autonomous vehicles, and how to secure them.
