Research on an attack knowledge based enhanced at-tack tree model

To resolve this issue of the documentation description and refined extent of the enhanced attack tree model, defined and formated to the type and the properties of the enhanced attack tree nodes, by the inductive analysis of the attack behavior, determined the level of abstraction of the enhanced attack tree model, achieved the format description of the attack behavior, established an effective attack pattern library; Moreover, by the classification of the attack behavior from the attack phase, the type of attacked operating system and the type of attacked target, achieved a pre-compiled attacks, reduced the search space of the attack pattern and improved the network attack graph generation speed and efficiency.
