Embodiment Construction

[0080] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0081] At first the technical terms used in the present invention are explained:

[0082] Network system: If the various objects of the network are set to a non-empty set A, and A satisfies

[0083] (1) A contains at least two different elements;

[0084] (2) The elements in A are related to each other in a certain way;

[0085] Then A is called a network system, and the elements of A are the components of the network system.

[0086] Behavior: Behavior refers to the homeomorphic transformation from one cover to another cover on the scene differential manifold;

[0087] Behavior path: Behavior path refers to a directed curve that connects the start and end points of behavior transformation and is smooth segment by segment.

[0088] Behavior paths have the following properties.

[0089] 1. Parallel movement of points The movement of any po...

Abstract

Aiming at a problem that measurement and evaluation of network service and application are currently in a rough comparison state and evaluation indicator systems and accurate measurement index values are unavailable, the invention discloses a network safety evaluation method based on attack-defense utility. The method includes steps of 1, determining scene differential manifold; 2, calculating a behavior path; 3, calculating behavior utility; 4, performing network attach-defense evaluation based on behavior utility.

Description

technical field [0001] The invention relates to a network security assessment method based on attack-defense confrontation utility, belonging to the technical field of network assessment. Background technique [0002] To accurately evaluate a system or program, the key is to objectively establish an evaluation index system and accurately measure index values. Utility is a basic measurement index to characterize the performance of a system or program, and is widely used in the evaluation of various systems or programs at all levels. In general physical systems, utility is represented as an "energy" characteristic. Using some basic physical quantities, according to the physical mechanism, it can be accurately combined and calculated. , it is difficult to accurately describe its utility. Generally speaking, the evaluation of such systems can only be carried out on the basis of rough comparative calculations. [0003] The network is a virtual space that supports the execution ...
