According to the security defense of Enterprise Network Information System, this paper proposes the "network business security" concept. Network Security is essential to any organization. Unlike the OSI model, the layers of security architecture do not have standard names that are universal across all architectures. The art and science of cryptography and its role in providing confidentiality, integrity, and authentication represents another distinct focus even though it's an integral feature of network security policy. It has made people realize that the data on the internet must be secured as many types of attacks are increasing day by day with the advancement of technology. Hence, this paper provides a comparative study of different ensemble learning methods such as Adaptive Boost, Gradient Boost, Random Forest, Extra Trees, and Logistic Regression based on classification performance and computational cost. Our aim is to show the new security framework in wireless network that the traditional wireless network does not have.
