Virulence and hazard analysis system for computer viruses

Abstract

The invention belongs to information security testing and evaluation technology, discloses a virulence and hazard analysis system for computer viruses, aims to test and evaluate the hazard of the computer viruses which comprise various malicious codes such as worms, Trojans and the like, provides a relatively perfect hazard testing and evaluation method, and provides quantitative reference indexes for virus prevention. The system introduces the idea of an analytic hierarchy process, and divides the aim of evaluating the computer viruses into two levels of hazardous factors; the system considers two user roles, allows professional users to set weights of each level of hazardous factors and requires the weights to pass positive reciprocal matrix property check and consistency check and provides a set of default weight vectors for the common users simultaneously; the system requires the users to set values for the second level of hazardous factors again; and the system acquires an estimated value of the hazard of the viruses through two levels of comprehensive fuzzy evaluation and gives a certain level in the five-level classification of the hazard of the viruses according to a maximum membership principle.

Description

technical field [0001] The invention belongs to the technical field of computer and information security, and in particular relates to a computer virus toxicity and hazard analysis system. Background technique [0002] With the development and popularization of computer and network technology, the harmfulness of malicious codes, mainly computer viruses, has gradually attracted the attention of individuals and society. A computer virus is a piece of program code that attaches to other programs and can reproduce itself. The new virus generated after replication also has the function of infecting other programs. It causes hardware damage, data loss or failure to use normally, file content leakage, etc., which brings great impact and loss to computer users. [0003] The harmfulness of computer viruses refers to the outbreak and prevalence time, scope of influence, transmission route, damage characteristics and damage consequences of a certain computer virus. However, as an imp...

AI Technical Summary

Problems solved by technology

[0005] First of all, the existing well-known anti-virus companies at home and abroad basically start from the source code of computer viruses to find the direct evidence of harm. also unpredictable

[0006] Secondly, there are a small number of information security organizations at home and abroad to evaluate the hazards of viruses based on the statistical results of the hazards. However, the statistical results are heavily dependent on the time of statistics, and they are done after the fact, often causing harm to the target object. The real-time and timeliness requirements are unsatisfactory

[0007] In addition, due to these current situations, for the same virus, different organizations have different levels of harm, and there are large differences between them, which affect the follow-up emergency treatment of computer viruses.
