Method for hierarchical managed password oriented access control to user access indications in a database of an SPS exchange

摘要

As protection against access by unauthorized persons, a hierarchically structured password-oriented access control, which can be managed with "special passwords", is provided for the administration and maintenance interface of a program-controlled communications system. Detailed "special passwords" provided are an administrator password by means of which essentially users with access authorization and their individual function authorizations can be specified. An administrator supervisor password can be used for specifying requirements which must be met before the processes intended under the administrator password are executed. Access to facilities of the program-controlled communications system is possible only with a manufacturer's password. Due to the flexibility of the access control, which can be achieved with the individual special passwords, optimal adaptation to the safety requirements of any system operator is achieved. IMAGE
