The analysis of services and mechanisms of information protection during transmission by channels with АТМ technology was made. Based on safety threats analysis the architecture of objects protection and safety threats of АТМ networks was defined. Classification of safety threats of АТМ networks according to formats of protocol blocks header fields is presented. The mechanism of protection against unauthorized access to address and control fields of ATM cells for the purpose of user connection security support by integrity and confidentiality of the transferred information is developed. As the result of analysis the propositions on information protection by АТМ technology were developed.
