1. A method of generating graphical models for providing security analysis in computer networks including the steps of:

  • providing an enterprise computer network;

    generating a type abstract graph independent of said particular network that models abstract dependency relationships among attributes and exploits using a software tool;

    generating a network-specific attack graph by combining said type abstract graph with specific information regarding said network using the software tool;

    monitoring an intruder alert; and

    generating a real-time attack graph of the network by correlating the intruder alert with said network-specific attack graph using the software tool.
