Information Security Countermeasures for Big Data Platforms Based on Cloud Computing

Nowadays, with advanced information technology, cloud computing, big data, and other technologies are widely used in various activities, and their value has been proven and attracted people's attention. This article aims to study the challenges faced by the development of national information security in the context of big data in the new era. While the big data platform brings convenience to social life, it will also have a major impact on national information security. In order to protect information security, big data needs to be managed to improve the quality and efficiency of its use. As a result of empirical analysis, information security in this environment is a personal issue as well as an important social issue. The way to solve this problem naturally starts from increasing people's awareness of preventing personal information and increasing the protection of commercial information, but it is necessary to improve relevant government laws and regulations, improve the government's information supervision capabilities, and clean up and optimize for the government. The unique role of the information environment is more important and more fundamental. In 2018, a total of 3 billion pieces of data were leaked worldwide, an increase of 70% compared to 2017. Information leakage occurs almost all the time, so we should effectively prevent information from being stolen.
