This paper presents the theoretical issues of data security in information systems, a practical implementation of the Clark-Wilson model on the example of Business Intelligence tool, performing the function of a telecommunications operator sales module, and an evaluation of the increase of security of the system created, using risk analysis.

This article describes an algorithm for procedural generation of underground systems with terrain features, by processing set of schematic maps. L-system and cellular automata are used to generate final system shapes. Most of existing algorithms are not suitable for application in computer games, since they usually lack any considerable level of control, require large amount of computation or produce overly complex meshes. We present our solution, that can produce editable 3D objects from very simple input, with high level of control over final system layout. We also allow evaluation at every key step of generation process. Presented approach incorporates placement of various terrain features with stalactites, stalagmites and columns as an example of such elements. Obtained results can be used in computer games or similar applications.
