ABOUT A MODEL OF FIREWALLING THE INTERCONNECTED CORPORATIVE INFORMATION AREAS USING PETRI NETS (rus.)
Shikhaliyev R.H.

In paper the model of firewalling of interconnected corporative information areas (ICCIA) is offered. For modelling are used Petri Nets (PN). The PN are a good approach for modelling of firewalling systems of ICCIA which enforce a policy of the access control on the basis of a filtration rules. The proposed model can be used for imitation and testing of system of firewalling ICCIA and check of a correctness of a security policy, carried out by it, also this model can be used as a basis for designing tools for the analysis of firewalling systems of ICCIA. (p. 19-25)

Keywords: Petri nets, interconnected corporative information areas, firewalling, filtration rules, packet.
