DSS - Directory System Server

Directory System Server (DSS) is a nationally developed directory server that aims to keep corporate user and certificate information at different levels in a reliable and consistent hierarchical structure and to present them in an uninterrupted, up-to-date and secure manner. The server provides quick access to this information in organizations that contain organizations, units, users and devices structured according to a certain hierarchy. DSS enables the implementation of high-level security policies, so that access and message exchange authorizations of users with different security levels can be determined in corporate use.

DSS has been developed according to international standards, taking into account national needs (military and institutional). Full compliance with ITU X.500, which is the most comprehensive set of standards created for directory systems, is also provided with LDAP, a more simplified directory access protocol. In this way, it can work with different military or commercial directory applications. Since DSS is a national product that does not contain commercial components, it can be quickly customized in line with corporate needs.
