Embodiment Construction

[0025] A switch is an important data-carrying tool in network applications. Users usually do not want strange devices to access the switch. The access of strange devices may affect the normal data transmission and reception, and even affect information security. For example, the user hopes that the access device of a certain switch is limited to traffic cameras in this area, so as to provide network data transmission services for traffic images in real time. If other devices are randomly connected to this switch, it will affect the normal transmission of video data and affect the security of traffic information.

[0026] One of the ways to protect the security of the switch is to identify and process the access device on the physical port of the switch. The existing technology sets an access control list for the port, which can also be called a white list. Add the MAC addresses of the devices that are allowed to connect to the switch to the white list. Normal data transfer. ...

Abstract

The invention provides a switch port security protection method and apparatus based on TCP / IP. A detection request message is sent to an access device via a switch physical port based on TCP / IP, the device information of the access device is identified by whether a reply message is received and the contents of the reply message, so that a switch issues blockage, release, white list and a series of strategies. Compared with the prior art, the device of the access device does not need to be manually determined, a switch port white list does not need to be manually set neither, thereby reducing the labor cost.

Description

technical field [0001] The present application relates to the communication field, in particular to a TCP / IP protocol-based switch port security protection method and device. Background technique [0002] The switch is an important data bearing tool in network applications, and the switch often needs to be oriented to various types of access devices. To ensure the port security of the switch, the reliability of the access devices must be guaranteed. Therefore, how to better manage the access devices Identification and prevention have become problems that need to be solved in network security. [0003] The existing technology usually uses a whitelist mechanism to control access devices and prevent access devices from attacking switches. The specific solution is: disable the MAC address learning function of ports, and add the MAC addresses of access devices that are allowed to port whitelist. [0004] The white list mechanism in the prior art needs to bind the MAC address of...
