Abstract
Description
Technical Field
[0001] This utility model relates to the field of network security monitoring technology, specifically to a system for monitoring network information security. Background Technology
[0002] Cybersecurity currently faces multiple challenges: traditional threats such as data breaches, ransomware, and phishing attacks remain prevalent, with increasingly sophisticated attack methods. Emerging technologies (such as AI and quantum computing), while enhancing defense capabilities, are also being used by attackers for automated attacks and encryption cracking. Vulnerabilities in IoT devices and cloud security risks are escalating, while a global shortage of cybersecurity talent and rising defense costs create a contradiction. Although countries are strengthening legislative oversight (such as data classification protection), attack targets have expanded from enterprises to critical infrastructure, exhibiting a trend towards scale and complexity, urgently requiring the construction of a dynamic and collaborative defense system.
[0003] Network information security monitoring is one of the effective technical means to address current network security issues. Chinese patent CN220957679U discloses a network security monitoring device that solves the problems of fixed installation and non-adjustable height in existing technologies by designing a mobile base and threaded connection. This enables convenient movement and height adjustment of the device, improving its flexibility and ease of installation. CN221922822U discloses a cloud platform-based security monitoring device, including a mounting rod and a camera. By adaptively adjusting the height of the camera, disassembly of the camera does not require personnel to climb with tools, facilitating operation.
[0004] Most of the above-mentioned technical solutions are designed to enable the installation of safety monitoring device components. However, how to enable the safety monitoring device to send early warning information in a timely manner is a technical problem that urgently needs to be solved in this field. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model proposes the following technical solution:
[0006] In a first aspect, this utility model provides a system for monitoring network information security, comprising: a controller, a local server electrically connected to the controller, a user authentication module, a wireless transmission module, and a wireless receiving module, wherein the wireless transmission module and the wireless receiving module are both wirelessly connected to a remote management terminal, and the local server is wirelessly connected to a remote server.
[0007] In one possible implementation, the user authentication module includes a fingerprint module, a facial recognition module, or a keypad. When a user needs to access data on a remote server locally, authentication is required through the user authentication module, including collecting the user's fingerprint information, facial information, and pre-set password information. Each user authentication attempt triggers a user authentication signal, which is directly sent to the controller of the security monitoring device.
[0008] In one possible implementation, a switching circuit is provided between the controller and the user authentication module. The first terminal of the switching circuit is electrically connected to the signal output terminal of the user authentication module, the second terminal is electrically connected to an internal power supply, and the third terminal is electrically connected to the controller. The control terminal of the internal power supply is also electrically connected to the controller. If the remote management terminal frequently receives user authentication behavior information from the controller, it sends a command to the controller to disconnect the user authentication module. Upon receiving the command, the controller drives the switching circuit to disconnect the communication connection between the user authentication module and the controller.
[0009] In one possible implementation, the switching circuit includes a first diode. The cathode of the first diode is electrically connected to the anode of the second diode and the signal output terminal of the user authentication module. The anode of the first diode is electrically connected to the anode of a third diode and the cathode of a fourth diode. The cathode of the third diode is electrically connected to the controller. The anode of the fourth diode is grounded. The cathode of the second diode is electrically connected to the anodes of the first and third diodes and the internal power supply. When the control voltage of the internal power supply is positive, the first and third diodes are turned on, while the second and fourth diodes are turned off, effectively turning the switching circuit on. The analog signal is transmitted from the user authentication module to the controller. When the control voltage of the internal power supply is negative, the first and third diodes are turned off, while the second and fourth diodes are turned off and on, effectively turning the switch off. The authentication signal from the user authentication module cannot flow to the controller through the switch, thus preventing requests to the local server.
[0010] In one possible implementation, the internal power supply is a bipolar pulse power supply, and the control terminal of the bipolar pulse power supply is electrically connected to the controller. A bipolar pulse power supply is a power device capable of outputting both positive and negative polarity pulse currents. The controller controls the bipolar pulse power supply to output positive or negative switching circuit control signals through its control terminal.
[0011] In one possible implementation, a signal amplification circuit is provided between the controller and the wireless transmission module. A first terminal of the signal amplification circuit is electrically connected to the controller, and a second terminal is electrically connected to the signal input terminal of the wireless transmission module. Since signal loss occurs during transmission, the signal amplification circuit amplifies the signal to ensure that the signal transmitted through the wireless transmission module can be successfully received by the remote management terminal.
[0012] In one possible implementation, the signal amplification circuit includes: a first resistor, a first terminal of which is electrically connected to the controller; a second terminal of which is electrically connected to a first terminal of a second resistor and an inverting input terminal of a first amplifier; a second terminal of the second resistor is electrically connected to the output terminal of the first amplifier and a first terminal of a load resistor; the non-inverting input terminal of the first amplifier is grounded; the second terminal of the load resistor is electrically connected to a first terminal of a third resistor and the output terminal of a second amplifier; the second terminal of the third resistor is electrically connected to an inverting input terminal of the second amplifier and a first terminal of a fourth resistor; the second terminal of the fourth resistor is grounded; and the non-inverting input terminal of the second amplifier is electrically connected to the controller. This signal amplification circuit connects inverting and non-inverting amplifier circuits together to form a bridge amplifier circuit. The input signal is shared by both operational amplifiers, and the output voltage signal is connected across the load resistor. If the operational amplifier gains of the two amplifiers are the same, the output signal will be doubled because this signal amplification circuit is a combination of the gains of two separate amplifiers.
[0013] In one possible implementation, the wireless transmission module includes a ZigBee wireless communication module, a Wi-Fi communication module, and a 4G / 5G mobile communication module. The ZigBee wireless communication module uses a short-range wireless communication protocol, enabling good network transmission over short distances. ZigBee advantages include low power consumption, low cost, low data rate, short range, low latency, large network capacity, license-free frequency band, high security, and reliable data transmission. The Wi-Fi communication module is a wireless communication module based on the IEEE 802.11 series of protocol standards. With the continuous optimization and development of Wi-Fi wireless communication technology, there are currently four main communication protocol standards: 802.11g, 802.11b, 802.11n, and 802.11a, each with two main operating frequency bands: 2.4GHz and 5.0GHz. Wired networks offer flexibility and the ability to penetrate walls. However, they are susceptible to external environmental influences, resulting in signal instability and insufficient security, making them vulnerable to attack. 4G and 5G are two high-speed mobile communication technologies. 4G is the fourth generation of mobile communication technology, an improvement and upgrade of 3G. 5G is the fifth generation of mobile communication technology, an improvement and upgrade of 4G.
[0014] In this embodiment, the user authentication module is used for legitimate users to access data information of a remote server through a local server. The controller will send the information from the user authentication module to the remote management terminal through the wireless transmission module. If the remote management terminal frequently receives user authentication behavior information from the controller, it indicates that a user may be frequently attempting authentication, and the user's access is illegal. The remote management terminal will then prevent illegal access by sending control commands to the controller. Attached Figure Description

Detailed Implementation
[0020] The present solution will now be described in conjunction with the accompanying drawings and specific embodiments.
[0021] See Figure 1 The system for network information security monitoring provided in this embodiment includes: a controller 1, a local server 2, a user authentication module 3, a wireless transmission module 4, and a wireless receiving module 5 electrically connected to the controller 1. The wireless transmission module 4 and the wireless receiving module 5 are both wirelessly connected to a remote management terminal 6, and the local server 2 is wirelessly connected to a remote server 7.
[0022] In this embodiment, the user authentication module 3 includes a fingerprint module, a facial recognition module, or a keypad. When a user needs to access data on the remote server 7 locally, authentication is required through the user authentication module 3, including collecting the user's fingerprint information, facial information, and pre-set password information. Each time a user performs authentication, a user authentication signal is triggered and directly sent to the controller 1 of the security monitoring device.
[0023] See further Figure 1 A switching circuit 8 is provided between the controller 1 and the user authentication module 3. The first terminal of the switching circuit 8 is electrically connected to the signal output terminal of the user authentication module 3, the second terminal of the switching circuit 8 is electrically connected to the internal power supply 9, and the third terminal of the switching circuit 8 is electrically connected to the controller 1. The control terminal of the internal power supply 9 is electrically connected to the controller 1. If the remote management terminal frequently receives user authentication behavior information from the controller 1, it sends a command to the controller 1 to disconnect the user authentication module 3. After receiving the command, the controller 1 drives the switching circuit 8 to disconnect the communication connection between the user authentication module 3 and the controller 1.
[0024] See Figure 2 The switching circuit 8 includes a first diode D1. The cathode of the first diode D1 is electrically connected to the anode of the second diode D2 and the signal output terminal of the user authentication module 3. The anode of the first diode D1 is electrically connected to the anode of the third diode D3 and the cathode of the fourth diode D4. The cathode of the third diode D3 is electrically connected to the controller 1. The anode of the fourth diode D4 is grounded. The cathode of the second diode D2 is electrically connected to the anodes of the first diode D1, the third diode D3, and the internal power supply 9. When the control voltage of the internal power supply 9 is positive, the first diode D1 and the third diode D3 are turned on, while the second diode D2 and the fourth diode D4 are turned off, which is equivalent to the switching circuit 8 being turned on; the analog signal is transmitted from the user authentication module 3 to the controller 1. When the control voltage of the internal power supply 9 is negative, the first diode D1 and the third diode D3 are turned off, while the second diode D2 and the fourth diode D4 are turned on, which is equivalent to the switch being turned off. The authentication signal of the user authentication module 3 cannot flow to the controller 1 through the switch, and therefore, the request to the local server 2 cannot be realized.
[0025] To enable the switching circuit 8 to open and close, the internal power supply 9 in this embodiment uses a bipolar pulse power supply, and the control terminal of the bipolar pulse power supply is electrically connected to the controller 1. A bipolar pulse power supply is a power device capable of outputting both positive and negative polarity pulse currents. The controller 1 controls the bipolar pulse power supply to output positive or negative control signals for the switching circuit 8 through its control terminal.
[0026] See further Figure 1 In this embodiment, a signal amplification circuit 10 is provided between the controller 1 and the wireless transmission module 4. The first terminal of the signal amplification circuit 10 is electrically connected to the controller 1, and the second terminal of the signal amplification circuit 10 is electrically connected to the signal input terminal of the wireless transmission module 4. Since signal loss occurs during transmission, the signal amplification circuit 10 amplifies the signal to ensure that the signal transmitted through the wireless transmission module 4 can be successfully received by the remote management terminal 6.
[0027] See Figure 3 The signal amplification circuit 10 includes: a first resistor R1, the first end of which is electrically connected to the controller 1; the second end of which is electrically connected to the first end of a second resistor R2 and the inverting input terminal of a first amplifier A1; the second end of the second resistor R1 is electrically connected to the output terminal of the first amplifier A1 and the first end of a load resistor RL; the non-inverting input terminal of the first amplifier A1 is grounded; the second end of the load resistor RL is electrically connected to the first end of a third resistor R3 and the output terminal of a second amplifier A2; the second end of the third resistor R3 is electrically connected to the inverting input terminal of the second amplifier A2 and the first end of a fourth resistor R4; the second end of the fourth resistor R4 is grounded; and the non-inverting input terminal of the second amplifier A2 is electrically connected to the controller 1. The signal amplification circuit 10 connects inverting and non-inverting amplifier circuits together to form a bridge amplifier circuit. The input signal is shared by both operational amplifiers, and the output voltage signal is connected across the load resistor RL. Since the operational amplifier gains of the two amplifiers are the same, the output signal will be doubled because the signal amplification circuit 10 is a combination of the gains of two separate amplifiers.
[0028] In this embodiment, the wireless transmission module 4 includes a ZigBee wireless communication module, a WiFi communication module, and a 4G / 5G mobile communication module. The ZigBee wireless communication module uses a short-range wireless communication protocol, enabling good network transmission over short distances. ZigBee advantages include low power consumption, low cost, low data rate, short range, low latency, large network capacity, license-free frequency band, high security, and reliable data transmission. The WiFi communication module is a wireless communication module based on the IEEE 802.11 series of protocol standards. With the continuous optimization and development of WiFi wireless communication technology, there are currently four main communication protocol standards: 802.11g, 802.11b, 802.11n, and 802.11a. Depending on the protocol standard, there are two main operating frequency bands: 2.4GHz and 5.0GHz. Wired networks are flexible and have wall-penetrating capabilities. Disadvantages include susceptibility to external environmental influences, signal instability, insufficient security, and vulnerability to attack. 4G and 5G are two high-speed mobile communication technologies. 4G is the fourth generation of mobile communication technology, an improvement and upgrade of 3G. 5G is the fifth generation of mobile communication technology, which is an improvement and upgrade of 4G.
[0029] As can be seen from the above embodiments, in this embodiment, the user authentication module is used for legitimate users to access data information of the remote server through the local server. The controller will send the information from the user authentication module to the remote management terminal through the wireless transmission module. If the remote management terminal frequently receives user authentication behavior information from the controller, it indicates that a user may be frequently attempting authentication, and the user's access is illegal. The remote management terminal then prevents illegal access by sending control commands to the controller.
