STANDARD SYSTEM MODELS FOR SUPPORT OF DECISIONS WITH RESPECT TO CONTROL OF SAFETY (SECURITY) OF INFORMATION

This paper examines the control of processes providing security of inf ormation in data processing networks with a large number of simultaneo us users and a complex structure of data-logic connections. The concep ts of centralizing control functions and applications of specialized s upport systems for decision making are utilized. The development-of Sy stems for supporting decision making is based on formalizing processes for providing security and assumes constant gathering, accumulation, and processing of data on the status of the data-processing network fo r optimizing the prevention of the loss of confidential information. T he approach to formalizing the process af providing security of inform ation is based on the use of Petri nets and their problem oriented ext ensions, which make it possible to solve problems of both standard and operative control of the aggregate means of protecting information. M odels and algorithms for realizing them are oriented to various classe s of data processing networks and permit the inclusion of topological features and the specifics of utilized methods for monitoring of the s tate of the data processing networks.
