Ensuring information security is a maintenance process that combines dynamic and static. First of all, you can use a series of protective tools, such as firewalls, operating system authentication, encryption, and so on. At the same time, use some dynamic detection tools. With the rapid development of Internet technology, big data, cloud computing, and other technical terms are no longer strange to people. Today's society is increasingly networked, creating a common platform for big data resource sharing and data communication in various industries. Big data and cloud computing technology have been applied to every field of human life with a strong penetration, resulting in technological innovation in various industries. Under the background of the rapid development of big data and cloud computing technology, the traditional enterprise form has been difficult to cope with the increasingly fierce competitive environment, making the electronic enterprise become the inevitable trend in the development and reform of enterprises in today's world. Electronic enterprises promote the efficient and vigorous development of enterprises, improve the speed, efficiency, and market competitiveness of enterprises, and better adapt to the changes in the market environment caused by big data and cloud computing. With big data and cloud computing as the background, this paper studies and analyzes the inevitability, basic characteristics, existing problems, countermeasures, and other basic information of enterprise electronization, so as to provide theoretical guidance for enterprise electronization. It has the ability to control the dissemination and content of information, ensure the censorship of information, and provide the basis and means of investigation for emerging network security issues.
