Embodiment

[0109] Such as figure 2 As shown, it is a specific implementation flow chart of the method of the present invention. Taking strategy P1 as an example, the parameters of strategy P1 are: [protocol type: TCP], [source IP address: 192.168.10.2], [virtual external network IP: 192.168.10.1 ], [virtual external network IP mask: 255.255.255.0], [source port: 1000], [intranet routing: no], [intranet gateway address: 0.0.0.0], [destination IP: 192.168.30.2] , [Virtual Intranet IP: 192.168.20.1], [Virtual Intranet IP Mask: 255.255.255.0], [Destination Port: 2000], [Extranet Routing: Yes], [Extranet Gateway Address: 192.168.20.2 ], the specific implementation includes the following steps:

[0110] 1) Import the policy configuration file on the device to the automatic detection system of the forward isolation device, and analyze the parameters of the strategy P1.

[0111] 2) The internal network and external network modules configure and deploy the IP addresses of the internal network ...

Abstract

The invention discloses a forward isolation device strategy automatic detection method and device. The method comprises the following steps: obtaining parameters of a detected strategy, wherein the parameters comprise an intranet side parameter and an extranet side parameter; determining communication addresses of an intranet side host and an extranet side host according to the internal and external network side parameters of the strategy; simulating network communication between the intranet side host and the extranet side host, and transmitting a forward transmission message and a reverse response message; and if the communication fails or the forward transmission or reverse response message is not received, determining that the detected strategy does not take effect. Whether each strategy is effective or not is automatically detected, fault diagnosis is conducted on the uneffective strategies, on one hand, the service reliability of the forward isolation device is guaranteed, and onthe other hand, the maintenance and management efficiency of the forward isolation device is improved.

Description

technical field [0001] The invention belongs to the technical field of forward isolating devices in electric power systems, and in particular relates to a method and device for automatically detecting strategies of forward isolating devices. Background technique [0002] The positive isolation device is an isolation device placed between the production control area (safety area I and safety area II) and the information management area (safety area III and safety area IV). The forward isolation device checks all received data packets, compares the information extracted from the packets with the configured policies one by one, forwards the packets that match the policies, and directly discards the packets that do not match the policies. [0003] In an actual application scenario, there may be hundreds of policies configured in the forward isolation device. If one of the policies does not take effect, the corresponding business cannot run normally. [0004] At present, there i...
