In the legal society, laws and regulations have a strong binding force, which can effectively regulate individual behaviors and ideas. Compared with western developed countries, China starts late in the application of cloud computing. Although relevant departments in China have issued the corresponding legal system, the laws and regulations on cloud computing network security are not sound enough. There are big loopholes so that some criminals can take advantage of, leading to the loss of **data** and important information in the computer. According to the current legal system, for illegal means to steal **data** information, damage user **data** and other acts, the punishment is relatively low. Facing with huge remuneration, it will lead to all kinds of illegal acts and incidents.
