Problems solved by technology

[0004] However, based on the existing technology, when an illegal terminal accesses the LAN, the access device will also store the correspondence between the IP address and the MAC address of the illegal terminal in the ARP table. The corresponding relationship between the IP address and the MAC address is stored in the security table, which causes the access device to release the illegal data packets sent by the illegal terminal, and the network security is poor.

Abstract

Embodiments of the present invention provide a message processing method and device, which relate to the technical field of network security. The method includes: acquiring terminal information stored in a Dynamic Host Configuration Protocol (DHCP) server, and the terminal information includes valid The terminal's Internet protocol IP address and media access control MAC address, according to the obtained terminal information and the preset update policy, update the security table, the security table stores the correspondence between the terminal's IP address and the MAC address, when receiving When receiving the data packet sent by the first terminal, obtain the IP address and MAC address of the first terminal carried in the data packet, if the security table contains the IP address and MAC address of the first terminal address entry, forward the data packet, and discard the data packet if there is no entry including the IP address and MAC address of the first terminal in the security table. By adopting the embodiment of the present invention, the security of the network can be improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a message processing method and device. Background technique [0002] At present, in order to prevent illegal users from stealing the Internet Protocol (English: Internet Protocol, IP) address of legal users to access the LAN and attack the LAN, the administrator can enable the security detection function on the access device. Specifically, a security table is stored in the access device, and the security table includes a correspondence relationship between an IP address and a Media Access Control (English: MediaAccess Control, MAC for short) address. The access device performs corresponding processing on the data packet sent by the terminal according to the stored security table. [0003] In the prior art, the safety table is usually created in batches. The access device acquires an Address Resolution Protocol (English: Address Resolution Protocol, ARP for short) tabl...
