Abstract： With the access of large-scale IoT devices and the wide application of edge computing， the potential attack surface of 5G network willalsoexpand，which willface morecomplex security risks.5G wireless communication technology has theadvantages of high speed，low latency，and largeconnectivity，but atthe same time，it also brings new network security chalenges.Large scale IoTdevices，edge computing and ultra-low latency requirements in 5G networks increase the potential attck surface. Starting from the characteristics of5G wireless communication technology，this article analyzes the security challnges faced by 5G wireless communication networks，and proposes effective solutions to these security issues，including intrusion detection technology，deep packet filtering technology，physical layer security enhancement technology，etc.，toachieve user privacy protection， data encryption，and intelligent intrusiondetection，improveatack response speedandriskdefensecapabilities，and ensure the security and stability of 5G wireless network communication.

Keywords： 5G; wireless communication technology; network security; defense technology
