Abstract
Various industries have adopted 5G Non-Public Networks to take advantage of improved
connectivity while remaining separate from public networks. As these networks support private
operations, they demand stringent security measures to prevent potential harm. This research
paper focuses on securing 5G non-public networks against fake base station attacks, which pose
a significant threat to the security of mobile networking. The study analyzes the risks associated
with fake base stations and reviews various protection methods. Our findings underscore the
importance of deploying effective countermeasures to mitigate the threats posed by fake base
stations in 5G Non-Public Networks.
