    Abstract: This study discusses the mechanism of a single access session for a particular user within a closed virtual environment system of distributed information resources as a secured portal network. The implementation of this session access model provides a user single authentication in the portal network, no matter what nodes were called firstly and subsequently. Thus, it defines only one arbitrary user entry point to the portal network.
