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
