摘要：【中文】本发明实施例公开了一种安全接入网关的准入控制方法、装置、设备和介质。该方法包括：接收用户终端发送的身份认证请求，并根据身份认证请求中携带的身份验证信息验证用户的身份；若对用户终端的身份验证通过，则根据身份认证请求中携带的属性信息查询用户终端的安全风险等级；根据用户终端的安全风险等级确定与用户终端对应的准入策略；根据准入策略控制用户终端连接目标服务器。本发明实施例能够对接入服务器的用户终端进行安全风险等级的分类，指定对应的准入策略，有效保证连接目标服务器时的安全性。 【EN】The embodiment of the invention discloses an admission control method, a device, equipment and a medium for a security access gateway. The method comprises the following steps: receiving an identity authentication request sent by a user terminal, and verifying the identity of a user according to identity verification information carried in the identity authentication request; if the identity of the user terminal passes the authentication, inquiring the security risk level of the user terminal according to the attribute information carried in the identity authentication request; determining an admission strategy corresponding to the user terminal according to the security risk level of the user terminal; and controlling the user terminal to connect with the target server according to the access strategy. The embodiment of the invention can classify the security risk level of the user terminal accessed to the server, appoint the corresponding access strategy and effectively ensure the security when connecting with the target server.
