Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0048] The gateway protection method and data labeling method provided by this application can be applied to such as figure 1shown in the application environment. Wherein, the user may perform login authentication on the authentication server 103 on the user terminal 102 . The domain name resolution server 106 can perform domain name resolution for the user's access request. The security gateway server 104 performs data communication with the user terminal 102 through the VPN 103, and can verify the validity of the domain name of the access request initiated by the user ...

Abstract

The invention relates to a gateway protection method and a data labeling method. In the gateway protection method, a legal user passes login verification of an authentication server, and the authentication server marks a specific label on an access request data packet sent by a user terminal and sends the access request data packet to a security gateway server; the domain name resolution server performs domain name resolution on the access request data packet, sends the resolved domain name information to the security gateway server, and sends an interception notification to the security gateway server if the resolution fails. And when the security gateway server works, the received access request data packet sent by any user terminal is verified, and the access with no specific label or illegal user domain name in the access request data packet is intercepted. Through dual authentication of the domain name and the identity tag, only the access request data packet which contains a specific tag and has a legal domain name can pass through the gateway, so that the gateway protection reliability is improved.

Description

technical field [0001] The present application relates to the technical field of network security protection, in particular to a gateway protection method and a data labeling method. Background technique [0002] The promotion of mobile applications meets the needs of accessing internal systems during remote office and on-site operations, and provides great convenience for enterprise employees. However, with the increasing number of users, the security issue of the mobile terminal is also extremely important. The introduction of VPN (Virtual Private Network, virtual private network) provides a solution for the secure access of enterprise resources. A number of key technologies are applied in VPN, among which network data packet interception is the most important technology. By filtering and intercepting data packets, it realizes the encrypted protection of application access and ensures that users can safely access the internal system of the enterprise. [0003] The existin...
