The subject of study is the process of building a model of the security system of the communication network of sociocybephysical systems (SCPS). The goal is to develop models for the synthesis of security components of the SCPS. The basis of the development is the technology of ultra-broadband signals that circulate in the information channels of the wireless network. Used methods: methods of analytical modeling and temporal position-impulse coding. The following results were obtained. An analytical model of the information transmission channel and its components - models of: information signals, antenna system block, system of reception and recognition of information signals - were developed. A criterion for the information efficiency of the SCPS system is proposed. The use of a synthesized ensemble of ultra-broadband signals in the communication channels of the SCPS wireless network - system allows wireless hidden transmission of information below the noise level by −3 … −6 dB without loss of information quality (probability of bit error 10–5- 10–6). In this way, the probability of detecting both the very fact of temporarily establishing communication channels and the impossibility of interference, distortion and interception of information becomes low.
