NOTES ABOUT (INJECTORS) POWER OVER ETHERNET. PART 3 DOI: 10.22184/2070-8963.2021.94.2.48.54
The article is devoted to the issues of Power over Ethernet technology - the development of injectors, their compatibility with other equipment, and operational problems. Over the years, periodically there were problems that the author had to solve and questions that required an answer. Some of them are briefly described in these notes, in the title of which the word "injectors" is placed in parentheses, since everything described applies, to a large extent, to PoE technology in general.

PoLAN TECHNOLOGY AS A NEW FORMAT OF THE LOWER LEVEL OF OFFICE BUILDINGS INFORMATION SYSTEMS DOI: 10.22184/2070-8963.2021.94.2.28.32
The variants of implementing the information infrastructure of movable objects based on the PoLAN passive fiber optic network technology under various scenarios of its implementation are analyzed. It is indicated that it is easy to switch to PoLAN technology when simple additional conditions are met. It is demonstrated that the greatest effect of using it in new construction is achieved when an active consolidation point or its equivalent is used in the horizontal part of the information wiring.

STANDARDIZATION OF SOLUTIONS AND SEGMENTATION OF THE TRANSPORT LEVEL OF THE 5G NETWORK DOI: 10.22184/2070-8963.2021.94.2.40.47
The article discusses the issues of standardization of solutions and segmentation of the 5G network transport level associated with the allocation of groups of compounds of various endpoints of the network at the transport level to achieve a specific SLA in the interests of the client. 5G network division on independently managed, controlled and custom segments (Network Slicing) will allow one network operator to manage multiple virtual networks for each of which, depending on the type of service provided, different values of delays, bandwidth, reliability, safety and security will be provided.

THE SUBSYSTEM OF AUTOMATED MANAGEMENT OF USER ACCESS RIGHTS TO INFORMATION RESOURCES OF THE ENTERPRISE DOI: 10.22184/2070-8963.2021.94.2.22.27
Nowadays, the activities of any enterprise are associated with the processing and large information amount storage in various, often decentralized information systems. Constantly appear new types of threats to unauthorized access to confidential information. The aim of the work is to reduce the risks of information security of the enterprise by creating the subsystem of automated management of users’ access rights to the enterprise information resources. The proposed models are built using a structural analysis and design approach adapted to solve information protection tasks, and are the basis for designing the subsystem of automated management of users’ access rights to information resources of the enterprise.
