Abstract: An access control method, performed by a client proxy apparatus running on a terminal device, includes intercepting a first negotiation packet. The first negotiation packet is from a first application client on the terminal device and is used to perform negotiation to establish a first session. The first session is between the first application client and a first server. The first session meets an encryption strength requirement. The method also includes adding authentication information corresponding to the first application client to a transport layer packet header of the first negotiation packet to obtain a modified first negotiation packet. The method further includes sending the modified first negotiation packet to a gateway device.

Abstract: This application relates to the field of network security technologies, and provides an access control method, an access control system, and a related device, to improve security of a protected application resource. The method includes: An SDP controller receives a first packet sent by a first SDP client device, where a TCP option field of the first packet carries a device identifier of the first SDP client device. The SDP controller performs single-packet authentication on the first SDP client device based on the device identifier of the first SDP client device. If the single-packet authentication on the first SDP client device fails, the SDP controller disables a TCP connection between the first SDP client device to which the first packet belongs and the SDP controller.
