Network information security is highly valued by the state and enterprises. However, in this context, the traditional enterprise anti-competitive intelligence system has been unable to meet the needs of the development of the network era. However, scholars have relatively limited research on anti-competitive intelligence and fail to provide practical guidance for enterprises to carry out effective anti-competitive intelligence work under the background of network information security. Therefore, based on the security characteristics and workflow of enterprise wireless communication network, this paper analyzes the security problems of wireless communication network and the attack sources that threaten enterprise intelligence, and puts forward measures and suggestions to protect enterprise competitive intelligence under the background of network security. Combined with the anti-competitive intelligence work of enterprises in network security, the anti-competitive intelligence work model of enterprises is constructed to provide guidance for the practical application of enterprises.
