Integration of security services in the architecture of telecommunications management systems

Abstract

The main tasks of providing the security of the management system of telecommunication networks in Ukraine are considered. Standards and other regulatory documentation on information security of telecommunications and their management systems were analyzed. Special attention is paid to issues of security management as a component of the functional architecture of the telecommunications management system according to the concept of building a TMN telecommunications management network. The peculiarities of the implementation of security services for terminal or intermediate nodes of telecommunication networks are determined. The hierarchical model of providing security services is compared with the model of open systems interaction. A practical model of the security organization of the telecommunications network management system is proposed. The main advantages and disadvantages of the integration of security services at the lower and upper protocol levels are studied. The integration of security services and security mechanisms into the telecommunications architecture is determined by two main considerations: in which nodes should the security services be implemented; at what level each service should be implemented. Because there are a number of arguments for and against each of these levels, there is no single correct solution to this problem. It is advisable to find the optimal solution, depending on the specific security problem.
