This paper presents an outline of a graphical tool designed as the first step of a project aiming at management of the security in information systems. Since the tool is constructed basing on the UML notation the most important principles and characteristics of this notation are also presented in this paper. The UML notation, which at present is gaining wide popularity, has already proved to be of considerable usefulness in many domains. Therefore its significance that is noticeable in field of information, especially its influence on the object-oriented programming and design should not be neglected.

The role-based access control (RBAC) model is one of the policies used to access control in the information systems. This powerful technology is very useful for managing the security of the information systems of the enterprises. In order to utilise its potential, the roles - the main component of this model - have to be properly constructed to reflect the organisational access control policy and the needs of the system. This requires the development of the components of the RBAC model in the correct way and implementation with the use of suitable tools. This paper presents the extension of the standard RBAC model and the implementation of this extension. The proposed approach is realised using the Unified Modelling Language (UML). The UML language was chosen because nowadays it is the standard tool, properly reflecting the description of the information system and its needs.
