Are false base station attacks a threat to 5G networks?
Abstract: The rapid advancement of 5G networks introduces new security challenges, particularly with the rise of false base station (FBS) attacks. This study investigates the vulnerabilities of 5G networks exploited by FBSs, which hijack communications by mimicking legitimate base stations and compromising user equipment (UE).
Are fake base station attacks still a threat?
With the rise of low-cost Software-Defined Radio (SDR) and open-sourced radio software, the possibility of fake base station attacks is increasing. Although security standards have improved over the years, these risks are still relevant to this day.
What happens if a base station is faulty?
The faulty base station establishes a radio connection with the user equipment and releases the connection afterward due to the worst channel conditions. Because our reference values come from the worst channel conditions, the optimal thresholds hence ensure fake base station detection with zero false positives under varying network conditions.
Are fake 5G base stations a security risk?
Benefit from features such as high bandwidth and massive machine-type communications, while being able to control their own private 5G networks. But fake base stations used by law enforcement and hackers may collect private information and cause disruptions in cell services, thus compromising the security.
What is a faulty base station vs a fake base station?
We varied the base station implementation to simulate legitimate vs. faulty but legitimate vs. fake and malicious base stations, where a faulty base station notifies the user of the connectivity disruption and releases the session, while a fake base station continues to hold the session.
Why is network security important in wireless communication base station monitoring?
With the rapid popularization of the network, under the increasingly complex network security situation and the increasingly prominent network security problems, network security occupies an important field in the wireless communication base station monitoring system, and has become a hot research direction.
