Research on Information Security of Large Enterprises

With the rapid development of information technology, the construction of large enterprise information system has entered the fast lane from point to surface and from shallow to deep. Enterprises increasingly rely on information system to play a role in its strategic planning and management. Meanwhile, new technologies and applications such as Cloud Computing, Internet of Things, Big Data and Mobile Internet has been proposed and developed. With the advance of the Internet Plus era, some enterprise information security issues have been discovered, and the security of information system has been challenged by complex network infrastructure, virus, and inefficient management, etc. Therefore, the security of enterprise information system has become an urgent problem for enterprises to solve. Based on several large enterprises as the research background, this paper describes current situation and challenge on large enterprise information system. To propose measures and solutions for the related problems, combined with our practical experience, we point out various information security issues and causes encountered by large group enterprises in the process of information system construction, operation and maintenance. Here, we propose a security strategy that combines security management with advanced technologies to address the above mentioned problems.
