Model Design of Big Data Information Security Management Based on the Internet of Things

Abstract

At present, the level of modernization and informatization is constantly improving, especially in rapidly developing China. A large amount of information is collected every second, forming a huge database and making people live in the "big data era."Following cloud computing and the Internet of things, big data technology has become another revolutionary change in the global society, changing global development and becoming a new development point for technological innovation, industrial policy, and national information security. Big data in the new age poses new challenges and perspectives for the nation's infosec development. Big data is a renewed tool for state security. Nations use big data to create state infosec, offering great facilitation, potential for adoption, and business value. This is a "new blue ocean"for competition among countries. Although big data brings convenience to public life, it also poses a serious threat to national information security. After the research and experiment of the model design of big data information security management of the Internet of things, the experimental data have shown that 86.67% set passwords in communication devices and storage devices. 66.67% installed firewalls, and 76.67% ran antivirus software. Compared with before, the total ratio of setting a password increased by 53.34% and the total ratio of installing a firewall and running antivirus software both increased by 26.67%. It can be seen from the above data that the protection of big data information under the Internet of things has been significantly improved. From the above data, through the big data information security management of the Internet of things, a new development direction is proposed for the development of information security.
