Problems solved by technology

[0009] It can be seen that if the existing detection method is used to scan the host, it will be very blind, resulting in too long overall scanning time
Moreover, the entire detection process lacks flexibility, and each step is highly dependent. Once a certain step is wrong, it needs to be readjusted, which takes a long time.

Embodiment Construction

[0048] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0049] The technical scheme of the embodiment of the present invention is divided into two steps as a whole, specifically as follows:

[0050] Step 1: Because industrial control systems have open IPs and ports, through extremely fast scanning, detect the openness of industrial control ports of nearly 4.3 billion IPs in the entire network, and obtain the IP collection of suspected industrial control systems.

[0051] Step 2: In the obtained IP collection of suspected industrial control systems, analyze the port protocol according to the open industrial control ports. If it ...

Abstract

The invention discloses an industrial control system detection method and device. The industrial control system detection method comprises the following steps: performing industrial control port scan on the IP of the entire network segment, and confirming a first IP set based on the scanning results, wherein the first IP set is a IP set of a suspected industrial control system; for each IP in the first IP set, performing corresponding protocol analysis based on the industrial control port corresponding to the IP, and screening out a second IP set from the first IP set based on the analysis results, wherein the second IP set is the IP set of the industrial control system; and obtaining the information of the industrial control system corresponding to the IP according to each IP of the second IP set.

Description

technical field [0001] The invention relates to the technical field of industrial control systems, in particular to a detection method and device for an industrial control system. Background technique [0002] With the rapid development of industrial control systems, many industrial control systems are integrated into the Internet environment. In the vast Internet environment, if the basic information of each industrial control system can be accurately grasped, such as IP, equipment information, function information, etc., it will promote the development of industrial control business. [0003] Currently, if figure 1 As shown, when detecting an industrial control system in the Internet environment, the following process is generally followed: [0004] Step 1: Randomly generate the target IP segment; [0005] Step 2: Randomly select the target port; [0006] Step 3: Detect the target port based on the target IP segment. The detection results include two types, one is tha...
