Description

Technical Field

[0001] The utility model relates to the technical field of network security, and more specifically, to an intelligent reminder type network security detection terminal. Background Art

[0002] The network security detection terminal is a key device for maintaining enterprise network security. It can monitor malicious attacks in real time and deeply analyze security data to reveal potential risks. After the network security detection terminal completes a comprehensive scan and evaluation, a large amount of detection data and reports will be generated. Staff members need to use removable storage devices (including but not limited to USB flash drives and external hard drives) to transfer the detection data from the detection terminal to a more secure storage environment or analysis platform for further exploration of potential security threats and formulation of effective protection strategies. After the data transfer is completed, the removable storage device needs to be removed in a timely manner to prevent data leakage and potential malicious access risks.

[0003] Traditional network security detection terminals do not have an obvious mechanism to remind staff members to remove the removable storage device in a timely manner after the data transfer is completed. This easily leads to the loss of the removable storage device. Seriously, the sensitive data stored in the removable storage device may be obtained by unauthorized personnel, greatly increasing the risks of data leakage and illegal use. Therefore, it is of great significance to solve the problem of how to timely remind staff members to remove and protect the removable storage device after the detection terminal finishes its work.

The t_out1 output terminal is connected to the r_in3 input terminal in the second-level reminder module. The t_out2 output terminal is connected to the input terminal of the controller.

[0055] It should be explained that the signal output from the t_out1 output terminal in the timing circuit indicates that the first specified time has been exceeded; the signal output from the t_out2 output terminal indicates that the second specified time has been exceeded.

[0056] The third-level reminder module includes a communication module. The controller sends information to the monitoring end through the communication module. The information content includes an encrypted password.

[0057] In this embodiment, the model of the communication module is SIM300C.

[0058] For easy understanding, the working process of the present utility model will be described as follows:

[0059] The detection terminal transmits data to an external mobile storage device through an interface. After the transmission is completed, the detection terminal sends a trigger signal to the controller.

[0060] The controller sends a PWM signal to the first-level reminder module according to the trigger signal, and the indicator light in the first-level reminder module starts flashing. At the same time, the first-level reminder module amplifies the PWM signal and outputs it to the pin 1 of the fifth AND gate U9 and the timing circuit in the second-level reminder module respectively. The timing circuit starts working, and the fifth AND gate U9 is in a waiting state.

[0061] If the accumulated timing of the timing circuit does not exceed the first specified time, the staff member unplugs the mobile storage device, the detection terminal sends a signal to the controller, the controller stops sending the PWM signal to the first-level reminder module, the indicator light stops flashing, and the timing circuit stops timing and resets;

[0062] If the timing circuit exceeds the first specified time, the timing circuit automatically outputs a control pulse signal to the r_in3 input terminal of the secondary reminder module through the t_out1 output terminal, the self-locking switch circuit is turned on and is in a self-locking state, the pin 2 of the fifth AND gate U9 receives the signal provided by the self-locking switch circuit, the pin 3 of the fifth AND gate U9 outputs a high level to the base of the fourth transistor Q4, the fourth transistor Q4 is turned on, the working circuit starts to work, the buzzer starts to sound intermittently, and the r_out2 output terminal outputs a signal to the t_in2 input terminal in the timing circuit, and the first AND gate U1 is in a waiting state; the primary reminder module continues to work;

[0063] If the accumulated timing of the timing circuit exceeds the first specified time but does not exceed the second specified time, the staff member unplugs the mobile storage device, the controller stops sending PWM signals to the primary reminder module, the indicator light stops flashing, and the controller outputs a control signal to the r_in4 input terminal in the secondary reminder module. At this time, the third transistor Q3 is turned on, the self-locking state of the self-locking switch circuit is released, the buzzer stops sounding, and the r_out2 output terminal stops outputting signals to the t_in2 input terminal in the timing circuit;

[0064] If the timing circuit exceeds the second specified time, the timing circuit automatically outputs a control signal to the controller through the t_out2 output terminal, and at the same time, the pin 2 of the first AND gate U1 receives the signal, and the pin 3 of the first AND gate U1 outputs a high level, which is transmitted to the pin 1 of the first counter U4 and the pin 1 of the second counter U6 through the first NOT gate U2, and the timing circuit is reset and no longer counts; the first-level reminder module and the second-level reminder module continue to work;

[0065] After receiving the control signal sent by the timing circuit, the controller sends a control instruction to the detection terminal, so that the detection terminal takes security measures such as encryption for the mobile storage device. The password set by the detection terminal is transmitted to the controller, and the controller transmits the password to the monitoring end through the communication module; the first-level reminder module and the second-level reminder module continue to work until the staff unplugs the mobile storage device.
