ABOUT ONE METHODICAL APPROACH TO THE ANALYSIS AND SYNTHESIS OF THE INFORMATION SECURITY SYSTEMS OF CORPORATIVE PORTALS

The general model of counteraction to threats of information security incident of corporative portals is considered. The general algorithm of an information security system's behavior is formulated. The detailed algorithm of the protection system functioning based on a combination of elements of antagonistic games and the combined twolevel discrete and parametrical adaptation and usage the achievable level of vulnerability as the key estimated indicator is suggested. The appropriate number and content of protection strategies and their interrelation with indicators of the current cost of the information resources of corporative portals is proved.
