Method and system for preventing IP (Internet Protocol) reverse checking

The invention relates to the field of information security, and discloses a method and a system for preventing IP (Internet Protocol) reverse checking, a system kernel adopts a virtualization component and is provided with a HOST space and a VM (Virtual Machine) space; the HOST space is used for accessing user verification; the VM space is used for carrying out intranet address binding on the verified user. The method has the beneficial effects that the user groups are classified and managed through the authentication component, the strategy component and the address component which are arranged in the HOST space, so that different user groups can obtain different IP outlets, and the technical effect of preventing the IP from being reversely checked is realized. 本发明涉及信息安全领域，公开了一种防止IP反查的方法及系统，系统内核采用虚拟化组件，设置有HOST空间和VM空间；HOST空间用于接入用户验证；VM空间用于将验证后的用户进行内网地址绑定。本发明有益效果是：通过HOST空间内设置的认证组件、策略组件、地址组件，对用户组进行了分类管理，可以使不同的用户组获取到不同的IP出口，实现了防止IP被反查的技术效果。
