Research on Information Security of Enterprise Group Financial Sharing in Cloud Computing Environment

With the continuous development of the economy and technology in the information age, a series of problems such as high financial cost, low efficiency of financial management and structural redundancy appear in large enterprise groups with large business scale and numerous subordinate groups. In this context, more and more enterprises have begun to provide services through financial sharing to solve internal problems. [1] At the same time, cloud computing promotes the construction of a highly process-oriented financial sharing operation system, and greatly improves the data storage capacity and computational analysis ability of the system. It can improve the quality of accounting information and provide technical support for the financial sharing service center of enterprise groups to better perform financial functions, enhance decision support and strategic impetus. However, with the increasing scale of financial sharing services of enterprise groups, the urgent problem to be solved is how to ensure the financial sharing services provided by enterprises in the cloud computing environment. This paper will take the AHP-fuzzy comprehensive evaluation method as the core, on the basis of a concise scientific principle, dynamic principle, objectivity principle and comprehensive principle, combined with index classification method, expert guidance method, questionnaire survey method and literature research method to complete the construction of financial sharing information security evaluation system, which will play a certain reference role in the information security research of financial sharing of enterprise groups.
