The invention discloses a general method for preventing a jump board machine based on Ethernet bridge rules. The method adopts a configuration mode of filtering data packets through Ethernet bridges, and uses ebtables, a configuration tool for filtering data packets at the data link layer in the Linux kernel. When a data packet is sent to a Linux host machine, the host machine detects and processes the filtering rules of the data packet and filters it. Since a honeypot deployed with multiple VLANs is bridged on the Linux host machine, when an attacker attacks the honeypot, ebtables is used to restrict the FORWARD chain. The FORWARD chain rules do not enter the user control and are responsible for forwarding data packets that flow through the host but do not enter the local machine. The invention adopts an Ethernet bridge rule, bridges multiple VLANs on the Linux host machine to create a large number of honeypots, and forms a honeynet deployed on a large scale. By limiting and allowing the operation of port traffic, the honeypot is independent of the real business and performs an anti-jump board operation.
