Construction of digital intelligent public security talent competency model and innovation of cultivation mode based on wireless security technology

Based on the actual needs of public security wireless network security, this paper constructs a multidimensional wireless security talent competency model and assessment system, integrating wireless protocol analysis, encryption algorithms, intrusion detection, software-defined radio (SDR) and other technical modules. A ‘theory-code-actual combat’ trinity training framework is designed, combining basic computer network security knowledge with practical skills such as vulnerability mining, reverse engineering, and wireless attack and defence techniques. Combined with real scenarios such as spoofing, jamming and rogue AP detection, a teaching mode combining CTF competition and range simulation was developed. The performance and training results of the model were analysed through experimental validation, showing a significant improvement in technical ability and hands-on reaction ability. The research provides theoretical and practical support for training wireless security professionals in the field of public security and helps to promote the development of wireless network security technology.
