By advancing enterprises information, enterprises can seek the most opportunities to contact with the outside, however, it brings some kinds of problem of enterprises information security, such as latent leakage of information resources due to employee's resignation, information resources lost due to abrupt malfunction of hardware equipment, information resources plagiarized by rival because of the low reliability of software, hidden trouble of information safety produced by incomplete system of information safety, etc.. According to the situation, in view of such four factors as hardware, software, stuff, and system, Information Safety-appraising & Optimizing Model of Enterprises Based on Informatization Environments (ISOMEBIE) is presented in this article. The model is solved by the means of Genetic Algorithms (GA), so its result has much more objectivity. This model can be used to direct enterprises to appraise its information safety, or to compare information safety with its rival. When the safety valve value of enterprises is below the normal level through application in this model, they should immediately take measure to find out and eliminate it, which enterprises can securely and reliably make full use of the results produced by informatization. 相似文献

审计是一门综合学科,具有要求专业的广泛性、实施操作的复杂性等特点,在具体审计实践中很难做到审计方法的模式化,也不可能千篇一律。因此,能够根据项目特点、围绕审计目标去组织项目,并在创新操作方法中去达到审计质量的最佳化就成为审计人员履行职责需要具备的基本素质之一。 相似文献
