Most of the key infrastructures of the current societies of the national civilians depend on industrial control systems (industrial control systems for short) to realize related operations. Once these important industrial control systems are damaged, lose functions or leak information, even endangering national security and public interest, it is necessary to effectively manage the assets (i.e. related equipment applied in the industrial control system, including SCADA, PLC, DCS, RTU, HMI, industrial switch, industrial operator/engineer station, etc.) in the industrial control system. In the existing method for managing industrial control assets, the industrial control assets which can be detected are limited, namely, all the industrial control assets cannot be managed; and for the detected industrial control assets, comprehensive information of the industrial control assets cannot be acquired.
Firstly, the present disclosure provides an industrial control asset management method, which collects and manages industrial control assets in an Ethernet network by using industrial protocols (i.e. communication message protocols between an upper computer and a control device and between the control device and the control device in an industrial control system, usually including read-write control of analog quantity and digital quantity) such as Modbus, S7, Ethernet/IP, Bacnet, etc., wherein the managed information includes manufacturer information, model, version, etc. However, because the industrial control assets in the ethernet are collected only based on the IP address, the devices that use the serial bus or other transmission media such as WLAN to communicate in the actual industrial environment cannot be collected and managed; moreover, because the managed information is single, when the equipment is replaced, the asset information cannot be updated in time, for example, the asset information of the new exchanged equipment cannot be collected again, and the situation that the information does not correspond to the actual object easily occurs, so that the management method cannot comprehensively collect and manage all the industrial control assets in the system, cannot update the state of the industrial control assets in real time, and ensures the validity of the information.
Based on this, referring to fig. 1, the present disclosure further provides an industrial control asset management method, where the management method includes steps S101 to S104:
in step S101, a corresponding transmission medium is determined according to the address information of each industrial control asset.
In this step, the transmission medium corresponding to each address can be determined according to the correspondence between the address type and the transmission medium. The address information of each industrial control asset is pre-stored in the information base, the address type of each address information is determined one by one according to the storage sequence in the information base, and then the transmission medium corresponding to each industrial control asset is determined according to the address type.
In one example, the address information of the industrial control asset includes: IP address, MAC address and master-slave address; the transmission medium includes: ethernet, WLAN and serial bus; among them, ethernet is a computer local area network technology. The IEEE 802.3 standard of the IEEE organization sets forth a technical standard for ethernet, which specifies the contents of the wiring, electrical signals, and medium access layer protocols, including the physical layer. Ethernet is currently the most commonly used local area network technology, replacing other local area network technologies such as token ring, FDDI, and ARCNET; the WLAN is a short for Wireless Local Area Network, and refers to a Network system that uses Wireless communication technology to interconnect computer devices to form communication and implement resource sharing, and is essentially characterized in that a communication cable is not used to connect a computer with a Network, but the computer is connected in a Wireless manner, so that the Network construction and the terminal movement are more flexible.
The HART protocol is a protocol widely adopted in the world at present, nearly hundreds of products adopting HART technology can be obtained from different suppliers, the complete variety of the products means that HART products can almost meet the requirements of all process application occasions, and the protocol supports the management of equipment information and is suitable for various networking conditions, so that industrial control assets can be collected by using the protocol. Traditional analog and discrete quantity devices can only communicate in a single process variable manner-thus it is difficult to find an easy way to determine if the transmitted information is valid. With the HART protocol, not only process variables but also other types of information can be obtained. Each HART device includes 35-40 standard information items, such as: the method comprises the steps of firstly, equipment state, diagnosis and alarm, secondly, process variable, unit, thirdly, loop current, percentage range, and thirdly, manufacturer and equipment labels. Other information includes: the host digitally queries the HART device and informs whether the device is properly set and functioning properly, which eliminates most of the routine inspection work and helps to discover process failures before they cause significant problems.
Referring to fig. 2, a method for determining a data transmission medium is shown, which specifically includes sub-steps S201 to S203.
In sub-step S201, in response to that the address information of the industrial control asset is an IP address, it is determined that a corresponding transmission medium is ethernet.
In sub-step S202, in response to the address information of the industrial control asset being a MAC address, it is determined that the corresponding transmission medium is a WLAN.
In sub-step S203, in response to the address information of the industrial control asset being a master-slave address, it is determined that the corresponding transmission medium is a serial bus.
Through the three substeps, three transmission media of Ethernet, WLAN and serial bus can be determined, so that a foundation is laid for subsequently acquiring industrial control assets in the three transmission media, and the problem that all industrial control assets in a system cannot be comprehensively collected and managed due to the fact that only industrial control assets in a single transmission medium (such as Ethernet) are acquired is solved.
With continued reference to fig. 1, in step S102, a corresponding transmission protocol is determined according to the transmission medium of each industrial control asset.
In this step, according to the correspondence between the type of the transmission medium and the transmission protocol, the transmission protocol corresponding to each transmission medium can be determined. In step S101, the transmission medium corresponding to each industrial control asset is already determined and stored in the information base, the type of each transmission medium is determined one by one according to the storage sequence in the information base, and then the transmission protocol corresponding to each industrial control asset is determined according to the type of the transmission medium.
In one example, the transmission protocol includes: HART-IP protocol, wirelessHART protocol, and HART protocol; the HART protocol uses FSK technology, superimposes a frequency signal on the process quantity of 4-20 mA signals, successfully and simultaneously communicates analog signals and digital signals in two directions without mutual interference, refers to an open interconnection model of the international standardization organization, uses a physical layer, a data link layer and an application layer of OSI standard, specifies a transmission physical form, a message structure, a data format and a series of operation commands, is a master-slave protocol, and only makes required response when the communication mode is question-answer. The HART protocol allows for 2 hosts in the system (say, one for system control and another for hand-held instruments for HART communication), and a maximum of 15 slaves can be connected to a pair of cables in a multi-drop system if analog signals are not required; in order to meet the increasing industry demand of acquiring data through the Ethernet, the HART Communication Foundation adds a new function on the HART protocol specification to form the HART-IP protocol; the WirelessHART protocol is a publicly available specification (IEC/PAS 62591ed.1) approved by the international electrotechnical standard committee (IEC), and is indeed the first industrial wireless communication technology to achieve this level of international certification worldwide.
Referring to fig. 3, a method for determining a transmission protocol is shown, which specifically includes sub-steps S301 to S303.
In sub-step S301, a transmission medium responding to the industrial control asset is ethernet; and determining that the corresponding transmission protocol is the HART-IP protocol.
In sub-step S302, the transmission medium responsive to the industrial control asset is a WLAN; the corresponding transmission protocol is determined to be the WirelessHART protocol.
In sub-step S303, the transmission medium responsive to the industrial control asset is a serial bus; the corresponding transmission protocol is determined to be the HART protocol.
The transmission protocols corresponding to the three transmission media of the Ethernet, the WLAN and the serial bus are determined through the three substeps, so that the corresponding transmission protocols can be adopted to request information in the corresponding transmission media, a foundation is further laid for acquiring industrial control assets in the three transmission media, and the feasibility of comprehensively managing all industrial control assets in the system is improved.
Referring to fig. 1, in step S103, information of each industrial control asset is requested according to the transmission protocol, and the received response information is stored in an information base, where the information of the industrial control asset includes asset information, status information, and configuration information.
In this step, the following operations are performed on each industrial control asset, the transmission medium of the industrial control asset and the address of the transmission medium are determined, then the transmission protocol corresponding to the transmission medium is adopted to generate a request packet, then the request packet is sent to the corresponding address to read the information of the industrial control asset at the address, and after the response information is received, the request packet is stored in the information base, namely after the asset information, the state information and the configuration information of the industrial control asset at the address are read, all the request packet is stored in the information base.
In one example, the address information is an IP address, a request packet may be generated by using the HART-IP protocol, and then the request packet is sent into the ethernet to read information of the industrial control asset at the IP address, and when the response information is received, the response information is stored in the information base, that is, the asset information, the state information, and the configuration information of the industrial control asset at the address are read, and all the asset information, the state information, and the configuration information are stored in the information base.
In one example, the address information is a MAC address, and a request packet may be generated using a WirelessHART protocol, and then the request packet is sent to the WLAN to read information of the industrial control asset at the MAC address, and when the response information is received, the response information is stored in the information base, that is, the asset information, the status information, and the configuration information of the industrial control asset at the address are read, and all of the asset information, the status information, and the configuration information are stored in the information base.
In one example, the address information is a master-slave address, and a request packet may be generated using the HART protocol, and then sent to the serial bus to read information of the industrial control asset at the master-slave address, and when receiving the response information, the response information is stored in the information base, that is, the asset information, the status information, and the configuration information of the industrial control asset at the address are read and all stored in the information base.
In one example, the information base is stored in the information base according to the relevance of the asset object, the asset information, the state information, the configuration information and the like by using a Bayesian classification algorithm, so that the efficiency of the later-stage matching and analyzing operation is improved. The Bayesian classification algorithm is a statistical classification method, which is an algorithm for classification by using probability statistical knowledge. In many cases, naive Bayes (A), (B)
Bayes, NB) classification algorithm can be compared with decision tree and neural network classification algorithm, the algorithm can be applied to a large database, and the method is simple, high in classification accuracy and fast in speed.
In step S104, the information of all the industrial control assets in the information base is classified according to a plurality of preset classification dimensions.
In this step, the information of the industrial control assets in the information base includes asset information, state information and configuration information, and further detailed information types may exist under the three information types. Some of the information categories are classified as classified dimensions, and data support can be provided for occasions such as later operation and maintenance upgrading, vulnerability analysis and mining, so that the classified dimensions can be preset as required. After the information of all the industrial control assets is acquired and stored according to the steps S101 to S103, the assets can be classified according to preset dimensionality, and a query page can be preset and displayed.
In one example, the preset classification dimensions include: one or more of a transmission, vendor name, device type, device software version number, device hardware version number, universal command document version number, transmitter specification version number, device identification, device status, and configuration information.
In the industrial control asset management method in the embodiment, because the transmission medium and the transmission protocol of each industrial control asset are determined, the industrial control assets in various transmission media can be obtained through various transmission protocols, and further, all the industrial control assets are guaranteed to be stored, so that all the industrial control assets can be managed; and the stored information of the industrial control assets comprises asset information, state information and configuration information, namely comprehensive information of the industrial control assets is obtained, and the information of the industrial control assets is classified according to multiple dimensions on the basis of comprehensive information, so that powerful data support is provided for occasions such as later operation and maintenance upgrading, vulnerability analysis and mining and the like.
Referring to fig. 4, some embodiments of the disclosure exemplarily show a method for checking information in an information base, which may be performed after storing information of an industrial control asset or simultaneously with requesting and storing information of the industrial control asset, and specifically, include steps S401 to S402.
In step S401, a first identifier of each industrial control asset is obtained according to information of each industrial control asset, where each industrial control asset has a unique first identifier.
In this step, an identifier is determined as a first identifier according to the content of the information of the industrial control assets, and then the identifier is obtained from the information of each industrial control asset for subsequent verification, which is equivalent to obtaining the identity information of each industrial control asset.
In one example, the first identification is a MAC address.
In another example, the first identification is a device ID number.
In step S402, in response to that the first identifiers of at least two industrial control assets are the same, generating warning information and deleting a wrong industrial control asset corresponding to the first identifier.
In this step, each first identifier is compared with all other first identifiers in pairs, and because the first identifiers of each industrial control asset are different, if two first identifiers are found to be the same, it can be determined that one of the two industrial control assets having the first identifier is wrong, and in order to ensure that the information of each industrial control asset is correct, warning information can be generated under the condition so as to remind a user of paying attention, and the specific warning information can be character information displayed on a warning page or voice information sent by an alarm; and then, deleting the wrong industrial control asset corresponding to the first identifier, specifically, determining which industrial control asset really has the first identifier by checking other information of the two industrial control assets corresponding to the first identifier, and then deleting the information of the other industrial control asset. The above description of this step is given by taking the case where the first identifiers of two industrial control assets are the same, and when the first identifiers of three or more industrial control assets are the same in the checking process, the operation of this step is completed according to the above description, but the difference is that information of two or more erroneous industrial control assets needs to be deleted.
Through the verification of the steps S401 to S402, the collected asset information and the asset object can be ensured to correspond to each other and keep synchronization all the time under the condition of reducing the influence on the original network environment as much as possible, and the problem that the asset synchronization can be ensured only by simply using a general exploration tool such as PING and the like to initially and slightly judge the equipment state or newly perform large-scale asset scanning originally is solved.
Referring to fig. 5, some embodiments of the present disclosure exemplarily show a method for monitoring information in an information base, which may be performed after storing information of an industrial control asset or simultaneously with requesting and storing information of the industrial control asset, and specifically, include steps S501 to S503.
In step S501, for each industrial control asset, information of the industrial control asset is acquired at preset time intervals.
In the step, a heartbeat frequency is dynamically adjusted by using a self-adaptive algorithm, the heartbeat detection is carried out on the collected asset objects, and the state and configuration information of the on-line equipment are requested at preset time intervals under the condition of reducing the influence on the original network environment as much as possible.
The self-adaptive (self-adaptive) means that in the process of processing and analyzing, a processing method, a processing sequence, a processing parameter, a boundary condition or a constraint condition is automatically adjusted according to the data characteristics of the processed data, so that the data are adaptive to the statistical distribution characteristics and the structural characteristics of the processed data to obtain the optimal processing effect.
In step S502, the acquired information of the industrial control asset is compared with the stored information of the corresponding industrial control asset.
In this step, a Hash algorithm may be used to compare the state information and configuration information in the obtained information of the industrial control asset with the state information and configuration information of the corresponding industrial control asset originally stored in the information base, if the two are consistent, it is determined that the industrial control asset is in a normal state, and if the two are different or offset, it is determined that the industrial control asset is in an abnormal state.
The Hash algorithm, generally translated as Hash, Hash or transliteration into Hash, converts an input (also called pre-mapped pre-image) of any length into an output of fixed length through the Hash algorithm, and the output is a Hash value. This transformation is a kind of compression mapping, i.e. the space of hash values is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from a hash value. In short, it is a function of compressing a message of an arbitrary length to a message digest of a certain fixed length.
In step S503, in response to that the acquired information of the industrial control asset is different from the stored information of the corresponding industrial control asset, the stored information of the corresponding industrial control asset is updated.
In this step, a request is made again for address information of the industrial control asset in the abnormal state, information of the industrial control asset at the address is obtained again, and the newly obtained information is stored in a corresponding position in the original information base in a covering manner.
Some embodiments of the present disclosure exemplarily show a method for acquiring address information of an industrial control asset, which specifically includes three manners, namely a manual acquisition manner, an automatic acquisition manner, and a manual and automatic combination manner.
The manual acquisition mode specifically includes: and displaying an address entry interface in advance, and storing address information entered based on the address entry interface.
This way the user stores all address information by manual entry. When industrial control assets in the system are installed, lists and records generally exist, a user can enter the assets based on the lists and the records, manual entry efficiency is low, and accuracy is difficult to guarantee.
The automatic acquisition mode specifically comprises the following steps: address information is acquired from each transmission medium in advance, and the acquired address information is stored.
The system has various transmission media, such as ethernet, WLAN and serial bus, etc., and the automatic acquisition mode acquires the address information of the industrial control assets in the system for each transmission medium, respectively, and the mode has high efficiency and high accuracy, but has certain errors.
The automatic combination mode of hand specifically is: the method comprises the steps of obtaining address information from each transmission medium in advance, displaying an address entry interface in advance, and storing the obtained address information and address information entered based on the address entry interface.
The method can be used for manually inputting on the basis of automatic acquisition, the omitted data can be automatically input in the manual inputting process, the automatically acquired errors can be corrected, the accuracy is guaranteed, and the efficiency is guaranteed.
Referring to fig. 6, some embodiments of the present disclosure exemplarily show a method for automatically acquiring address information of an industrial control asset, which specifically includes steps S601 to S603, where each step is specific to one transmission medium, and address information in three transmission media can be automatically acquired through three steps, and the three steps are not limited in sequence, and may be performed simultaneously or sequentially.
In step S601, a port in a network segment of the ethernet is probed to obtain an IP address of a live port.
In this step, the TCP/UDP5094 port in the network segment is probed, and the IP address for opening the port is determined.
In step S602, a WLAN environment is sniffed wirelessly, and a MAC address that can be matched with any MAC address in the MAC address library of the industrial control device is obtained from a WLAN packet in the environment.
In the step, a wireless network sniffing mode is used for capturing a WLAN packet in an environment, MAC addresses in the packet are analyzed and separated, then a Sunday algorithm is used for matching the MAC addresses with an industrial control equipment MAC address base, relevant industrial control asset MAC addresses in the environment are matched, if the industrial control equipment MAC address base has one of Emerson application Motors and Controls with an MAC address prefix of 00243D, if the MAC address prefix of a message source destination in the environment is matched to 00243D, the situation that equipment relevant to industrial control exists in a field environment is indicated, and the corresponding MAC addresses are added into an information base.
The Sunday algorithm is the string pattern matching proposed by Daniel m. The core idea is as follows: in the matching process, when the mode strings are found to be unmatched, the algorithm can skip as many characters as possible to carry out the next matching, and therefore the matching efficiency is improved.
In step S603, the slave address of the serial bus is scanned to obtain the slave address of the packet to be sent back.
In this step, a broadcast packet is transmitted from the master station address, then the slave station address is scanned, and if a relevant return packet is received, the corresponding slave address is stored in the information base.
Referring to fig. 7, a detailed flowchart of the industrial asset management method including the checking step is shown.
