The overall architecture includes the infrastructure layer, data layer, system support layer, application layer and presentation layer. Considering the scalability of the system, the data and business application system expansion network architecture is realized. The visualization analysis device of the prototype system of the railway information asset mapping platform is an analyzer, which is mainly used for massive data correlation analysis. Because the information involved is relatively scattered, the data structure may not be unified, and it is usually mainly manual analysis, coupled with the unstructured and uncertain analysis process, it is not easy to form a fixed analysis process or mode, and it is difficult to transfer the data into the application system for analysis and mining. With the help of a powerful visualization data analysis platform, manual operation can be assisted to analyze the data and make a complete analysis chart. The chart contains relevant information of all events, and also fully displays the process of data analysis and the direction of data chain. At the same time, these analysis charts can also be saved in other formats for relevant personnel to read.

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Based on the security requirements for preventing security attacks, the security goals that need to be achieved, the security services required by the corresponding security mechanisms, and other factors, referring to international standards such as SSE-CMM ("System Security Engineering Capability Maturity Model") and ISO17799 (Information Security Management Standard), and in accordance with the requirements of the National Standard of the People's Republic of China GB / T 22240-2008, we comprehensively consider the feasibility, manageability, scalability, comprehensive completeness, system balance and other aspects. In the overall design process of the network security prevention system, we follow the following 6 principles.

[0047] The holistic principle of network information security

[0048] It is required that in the event of a network attack or destruction, the services of the network information center must be restored as quickly as possible to reduce losses. Therefore, the system provides security protection mechanisms, security detection mechanisms, and security recovery mechanisms. The security protection mechanism is a corresponding protective measure taken according to various security threats existing in the specific system to avoid illegal attacks. The security detection mechanism is to detect the operation of the system and promptly discover and stop various attacks on the system. The security recovery mechanism is to carry out emergency processing and restore information as much as possible and in a timely manner in the event of the failure of the security protection mechanism to reduce the degree of damage to the supply.

[0049] Safety evaluation and balance principle

[0050] Establish a reasonable and practical security and user demand evaluation and balance system. The security system design should correctly handle the relationship between demand, risk and cost, make security and availability compatible, and make it organizationally executable. There is no absolute evaluation standard or measurement indicator for evaluating whether information is secure. It can only be determined by the user needs of the system and the specific application environment, which depends on the scale and scope of the system, the nature of the system and the importance of the information.

[0051] Standardization and consistency principles

[0052] System construction is a huge system project, and the design of its security system must follow a series of standards to ensure that the entire system can be safely interconnected and information sharing can be achieved.

[0053] The principle of combining technology and management

[0054] The safety system is a complex system engineering, involving elements such as people, technology, and operation. It is impossible to achieve it by technology or management alone. Therefore, it is necessary to combine various safety technologies with operation management mechanisms, personnel ideological education and technical training, and the construction of safety regulations and systems.

[0055] Hierarchical principle

[0056] The hierarchical principle refers to the security hierarchy and security level. The system adopts the information system level two for relevant design, and provides comprehensive and optional security algorithms and security systems for different levels of security objects to meet various practical needs at different levels in the network.

[0057] Dynamic development principle

[0058] When designing system security, security measures must be continuously adjusted according to changes in network security to adapt to the new network environment, and the system design must meet new network security requirements.

[0059] Therefore, according to the system security principles, we carry out system security design from eight aspects: physical security, host security, network security, application system security, data security and backup and recovery, security management system, security management organization, and personnel safety management.

[0060] The following is combined with Figure 1-7 The present invention is further described with examples:

[0061] A railway network security risk visualization analysis method includes the following steps:

[0062] Step 1: Position the railway network security risk visualization analysis device, for example, on a desktop or workbench;

[0063] Step 2: Use the equipment body of the railway network security risk visualization analysis device to obtain and analyze the railway network security risk data, and classify the railway network security risk data into primary risk data, intermediate risk data and advanced risk data; for example, according to the severity of the harm that can be caused by the railway network security risk data, it is divided into primary risk data, intermediate risk data and advanced risk data. These three risk levels are the first safety level.

[0064] Step 3: Classify each type of risk data mentioned above into hardware risk, software risk and human risk according to the nature of the event; for example, hardware risk is hardware failure risk, fire risk or flood risk, etc. For example, software risk is software data storage risk, data crash risk, data error risk and logic error risk, etc. Human risk is virus risk, illegal access risk, visitor surge risk and out-of-domain visitor risk, etc.

[0065] Step 4: assign different second security levels to hardware risk, software risk and human risk respectively;

[0066] Step 5: Graphically process the hardware risk and software risk in each type of risk data, and encrypt the human risk; for example, encrypt the visitor's name, ID number, etc. of the human risk.

[0067] Step 6: Receive the input account information and compare and identify the first permission level to which the account information belongs;

[0068] Step 7: Capture one of primary risk data, intermediate risk data, or advanced risk data according to the first permission level;

[0069] Step 8: Identify the second permission level based on the account information, and capture and display one of the hardware risk, software risk or human risk based on the second permission level.

[0070] For example, the first security level includes primary level, intermediate level and advanced level, which correspond to capturing primary risk data, intermediate risk data and advanced risk data respectively. The second security level includes the first nature level, the second nature level and the third nature level, which assign the hardware risk, software risk and human risk to the first nature level, the second nature level and the third nature level respectively.

[0071] During use, when the user inputs the account information into the railway network security risk visualization analysis device, the device body can capture one of the primary risk data, intermediate risk data or advanced risk data according to the first permission level associated with the account information, and then capture one of the hardware risk, software risk or human risk in the above risk data according to the second permission level associated with the account information and display it, so that the account risk authority can be divided into two levels. Specifically, according to the nature of the user's work (for example, if the user's work nature is a hardware engineer, hardware risk data is captured, if the user's work nature is a hardware engineer, software risk information is captured, and if the work type is an analysis engineer, human risk data is captured), according to the two-level permissions of the account, first determine to capture one of the primary risk data, intermediate risk data and advanced risk data, and then capture one of the hardware risk, software risk or human risk in the above risk data, thereby avoiding the information leakage risk brought by the first-level permission, realizing the refined management of railway network security risks, so that people who do not have the corresponding permission level cannot obtain information beyond the first permission level and the second permission level, reducing the management and control risks.

[0072] For example, if the second authority level is the hardware level, the risk information corresponding to the first nature level will be captured; if the second authority level is the software level, the risk information corresponding to the second nature level will be captured; if the second authority level is the manual level, the risk information corresponding to the third nature level will be captured.

[0073] In one embodiment, before step 1, the process further includes adding and storing account information, the account information including name, work number, address, first permission level and second permission level, wherein the first permission level is associated with the name, and the second permission level is associated with the first permission level. In one embodiment, when the first permission level is missing, the account information is not stored. That is, each account information must determine the first permission level, but does not necessarily need to set the second permission level.

[0074] In one embodiment, when the second permission level is missing, step eight is specifically: identify the second permission level according to the account information, and if the second permission level information is missing, display all hardware risks, software risks and human risks of a risk data category corresponding to the first permission level. For example, when the nature of the manager's work is broad or global control, the three risks can be viewed at the same time.

[0075] In one embodiment, in order to improve the positioning effect of the equipment body, step one is specifically: utilizing the auxiliary area of ​​the railway network security risk visualization analysis device to increase the movement of the mechanism, increase the support area of ​​the equipment body, and synchronously link the gripping mechanism to move to realize the gripping action of the equipment body.

The setting of the area increasing mechanism 3 can realize the increase of the area of ​​the regulating support handle 2, thereby preventing the device from tipping over when placed, and the structural design of the area increasing mechanism 3 is reasonable. During use, the adjustment function can be realized, so that the area of ​​the regulating support handle 2 can be increased by loosening, thereby preventing the device from tipping over, and it can also be recovered to facilitate the taking of the regulating support handle 2.

[0081] In this embodiment, a gripping mechanism 6 is provided in the auxiliary area enlargement mechanism 5, and the gripping mechanism 6 includes an arc-shaped gripping plate 61 and a rotating support plate 62. The arc-shaped gripping plate 61 is arranged on the circumference of the rotating support plate 62, and the rotating support plate 62 is fixedly sleeved outside the rotating rod 63, and the rotating rod 63 is rotatably arranged in a rotating groove 64 opened on the auxiliary area enlargement plate 56. A push-pull rod 65 is also hinged on the circumference of the rotating support plate 62, and the free end of the push-pull rod 65 is hinged on the top wall of the auxiliary movable groove 57. In the present invention, a gripping mechanism 6 is added. The setting of the gripping mechanism 6 can ensure that the equipment is better prevented from tipping over when placed by gripping the support table, and the structural design of the gripping mechanism 6 is reasonable, which can not only grip the support table, but also play a supporting role, so that the sagging force of the equipment body 1 can be buffered, thereby achieving a better effect of preventing tipping over.

[0082] The present invention also provides a method for using a railway network security risk visualization analysis device, comprising the following steps:

[0083] When the device needs to be placed, the support area of ​​the control support handle 2 and the platform can be increased to prevent the device from tipping over. Specifically:

[0084] Manually adjust the locking mechanism 4 so that the locking mechanism 4 completes the unlocking of the L-shaped area enlargement plate 35, ensuring that the L-shaped area enlargement plate 35 can move to the outside of the first installation slot 31 under the push of the push support assembly 33, thereby increasing the relative area of ​​the control support handle 2. Specifically, manually grasp and press the adjustment plate 44 so that the press adjustment plate 44 moves with the locking plate 42 into the third installation slot 43, thereby ensuring that the locking plate 42 moves to the outside of the locking slot 41. At this time, the locking mechanism 4 realizes the unlocking process, and the L-shaped area enlargement plate 35 can move to the outside of the first installation slot 31 under the push of the push support assembly 33. In this way, under the combined action of the L-shaped area enlargement plate 35 and the control support handle 2, the support area of ​​the analyzer can be increased, thereby preventing the analyzer from tipping over.

[0085] At the same time, during the movement of the L-shaped area enlargement plate 35, the auxiliary area enlargement mechanism 5 will be driven to move. The movement of the auxiliary area enlargement mechanism 5 will assist in increasing the area of ​​the L-shaped area enlargement plate 35. Specifically, during the movement of the L-shaped area enlargement plate 35 outward from the first mounting groove 31, the contact plate 51 will lose its contact with the contact block 53. In this way, under the pulling of the second supporting spring 543, the contact block 53 will be moved to the left through the guiding supporting block 541. The leftward movement of the contact block 53 will cause the inner spiral tube 553 to rotate through the spur rack 551 and the driving gear 552. The rotation of the inner spiral tube 553 will cause the inner spiral rod 554 to move outward from the moving through hole 555. In this way, under the action of the inner spiral rod 554, the auxiliary area enlargement plate 56 will be moved outward from the auxiliary moving groove 57 through the transverse connecting plate 558. Therefore, under the combination of the auxiliary moving groove 57 and the L-shaped area enlargement plate 35, the area of ​​the equipment can be further increased, thereby achieving a better anti-dumping effect.

[0086] In addition, while the auxiliary area increasing mechanism 5 assists in increasing the area, it will synchronously link the gripping mechanism 6 to move, ensuring that the gripping mechanism 6 can grip the ground, thereby better preventing the equipment from tipping over. Specifically, when the auxiliary area increasing plate 56 moves out of the auxiliary moving groove 57, it will push the rotating support plate 62 to rotate through the push-pull rod 65. The rotation of the rotating support plate 62 will cause the arc-shaped gripping plate 61 to rotate, and the rotation of the arc-shaped gripping plate 61 will grip the support platform.

[0087] The present invention also provides a railway network security risk visualization analysis device adopted by the above railway network security risk visualization analysis method.

[0088] Beneficial effects of the present invention:

[0089] The present invention improves the structure of the existing analyzer. The improved analyzer increases the area of ​​the supporting structure, thereby preventing the analyzer from tipping over when placed. At the same time, the increased area can achieve automatic adjustment, so that the device can be more convenient to pick up through the adjustment effect.

[0090] In the present invention, an area increasing mechanism 3 is added to the regulating support handle 2. The setting of the area increasing mechanism 3 can increase the area of ​​the regulating support handle 2, thereby preventing the device from tipping over when placed, and the structural design of the area increasing mechanism 3 is reasonable. During use, the regulating effect can be achieved. In this way, the area of ​​the regulating support handle 2 can be increased by loosening it, thereby preventing the device from tipping over, and it can also be recovered to facilitate the taking of the regulating support handle 2.

[0091] In the present invention, a locking mechanism 4 is added to the area enlargement mechanism 3 , and the setting of the locking mechanism 4 can be used to lock the L-shaped area enlargement plate 35 . Specifically, under the action of the locking mechanism 4 , the L-shaped area enlargement plate 35 can be locked in the first installation groove 31 .

[0092] In the present invention, an auxiliary area enlarging mechanism 5 is additionally provided, and the auxiliary area enlarging mechanism 5 is used to assist in increasing the area of ​​the L-shaped area enlarging plate 35, so as to better prevent the equipment from tipping over.

[0093] The present invention further provides a gripping mechanism 6, which can ensure that the device is better prevented from tipping over when placed by gripping the support table. The gripping mechanism 6 has a reasonable structural design, which can not only grip the support table, but also provide support, thereby buffering the downward force of the device body 1, thereby achieving a better effect of preventing tipping over.

[0094] The structural design of the present invention is reasonable. When the L-shaped area enlargement plate 35 moves out of the first installation groove 31, the auxiliary area enlargement mechanism 5 and the gripping mechanism 6 can be synchronously driven to move, which can reduce the operating difficulty of the equipment and ensure the high efficiency performance of the equipment.

[0190] Data security and backup recovery:

[0191] Data security and backup and recovery are designed with security in mind, including data integrity, data confidentiality, data backup and recovery.

[0192] (1) Data integrity

[0193] It is recommended to use a dual-machine hot standby method with shared storage (disk array, English abbreviation RAID) to provide protection for data integrity. The shared storage method mainly provides data integrity and continuity after switching through the disk array. User data is generally placed on the disk array. When the host fails, the backup machine continues to obtain the original data from the disk array. This method generally has higher storage security. Therefore, if we ignore the case of storage device failure, this method is also the most widely used backup method in the industry.

[0194] (2) Data confidentiality

[0195] Since the network assets and network security data displayed in the system are confidential data of the unit, once leaked, they may be attacked by hackers or other organizations, causing network security problems. Therefore, all database data sources in the system support database-level security mechanisms, such as data access permission settings, database audit mechanisms, log tracking mechanisms, backup and recovery mechanisms and other security measures.

[0196] (3) Data backup and recovery

[0197] The database is the basis for the operation of C / S and B / S systems. The prototype system of the railway information asset mapping platform needs to operate efficiently and safely, so the system needs to provide a complete data recovery and backup mechanism. In the event of an emergency, the data required by the system can be quickly restored, and the files to be restored can be specified. The system provides two operations: manual backup, recovery, and scheduled backup.

[0198] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
