[0001] This invention relates to the field of server technology, and specifically to a server chassis intrusion detection device and method. Background Technology

[0002] With the rapid development of the information technology industry, the demand for servers is increasing, and consequently, security protection is becoming increasingly important. During server operation, to avoid wasting significant resources analyzing root causes of problems not caused by equipment malfunctions, such as information leaks, overheating issues, or component damage due to unauthorized opening of the server chassis, it is essential to install intrusion detection modules on the server chassis. Unauthorized opening of the server chassis is strictly prohibited to prevent unnecessary problems.

[0003] Currently, servers all use mechanical switches for triggering. However, as time goes on and the number of uses increases, the stability and accuracy of this function deteriorates, leading to an increased false alarm rate or damage, which affects server operation and maintenance.

Furthermore, it detects server chassis intrusion based on server cover opening / closing signals, server cover locking signals, and intrusion detection module presence signals, thus solving the problem of false intrusion triggering. This invention achieves intrusion detection of the server chassis and improves the stability and accuracy of server chassis intrusion detection.

[0009] In one optional implementation, the intrusion detection module includes: a microcontroller, a distance sensor, a first pressure sensor, a second pressure sensor, a power supply module, and a first Bluetooth module; the microcontroller is connected to the distance sensor, the first pressure sensor, the second pressure sensor, the power supply module, and the first Bluetooth module, respectively; wherein,

[0010] A distance sensor is installed on the top cover of the server chassis to collect the distance between the top cover and the server chassis. Based on the distance between the top cover and the server chassis, the sensor determines the opening and closing data of the server cover and transmits the server cover opening and closing data to the microcontroller.

[0011] A first pressure sensor is located at the first fixing bolt to collect pressure data from the first fixing bolt and transmit the pressure data to the microcontroller; wherein, the first fixing bolt is located on the rear side of the server chassis cover.

[0015] This invention provides a server chassis intrusion detection device. It uses a first pressure sensor and a second pressure sensor to collect bolt pressure data, thus characterizing the chassis's locking state. A distance sensor collects the opening and closing status of the chassis cover, and a power module collects wireless power supply data.

[0016] In one alternative implementation, the motherboard includes: a second Bluetooth module and a baseboard controller; the second Bluetooth module and the baseboard controller are connected; the second Bluetooth module and the first Bluetooth module are wirelessly connected.

[0017] The second Bluetooth module is used to transmit the server cover opening / closing signal, server cover locking signal, and intrusion detection module presence signal transmitted by the first Bluetooth module to the baseboard controller.

[0018] The baseboard controller is used to determine whether there is an intrusion into the server chassis based on the server chassis opening / closing signal, the server chassis locking signal, and the intrusion detection module presence signal, and to generate server chassis intrusion detection results.

[0019] The present invention provides a server chassis intrusion detection device, which realizes data interaction between the intrusion detection module and the motherboard through a wireless connection between the second Bluetooth module and the first Bluetooth module.

[0020] In one alternative implementation, the baseboard controller is specifically configured to determine that an intrusion has occurred in the server chassis and issue an alarm when the intrusion detection module's in-situ signal is low and no server chassis opening / closing signal or server chassis locking signal is detected.

[0021] The present invention provides a server chassis intrusion detection device, which realizes the detection of the presence of the intrusion detection module in the initial state through the baseboard controller.

[0027] The present invention provides a server chassis intrusion detection device. The baseboard controller limits the security status of the server chassis. Specifically, the server chassis security can only be guaranteed when the server cover opening / closing signal, the server cover locking signal, and the intrusion detection module presence signal are all at high level, thus ensuring the stability and accuracy of server chassis intrusion detection.

Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0042] Figure 5 This is a flowchart illustrating a server chassis intrusion detection method according to an embodiment of the present invention. Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, the intrusion detection scheme used by the relevant servers is as follows: the intrusion detection switch is mechanically triggered and installed on the inner wall of the server chassis. The movable lever is slightly higher than the upper edge of the inner wall of the server chassis. When the server chassis cover is closed, the movable lever is pressed down, triggering the button switch. The electrical signal is transmitted to the BMC microcontroller (Baseboard Management Controller) through the cable, informing the BMC microcontroller that the chassis cover is closed. When the chassis cover slides out and is removed, the movable lever pops up, triggering the button switch, transmitting the electrical signal to the BMC microcontroller, informing the BMC microcontroller that the chassis cover is open.

[0045] The intrusion detection schemes used in the aforementioned servers have the following drawbacks: ① They employ open-type mechanical intrusion detection switches, which are exposed to the environment and constantly in use. As the server's operating time increases, the mechanical switches will inevitably face the risk of aging and failure, leading to decreased stability and false alarms; ② The signals are transmitted to the BMC via cables. As the server's operating time increases, the cables may age and become damaged, causing the server's intrusion detection function to fail, failing to record operations such as opening the chassis, and introducing some security risks.

[0046] To achieve cable-free intrusion detection for server chassis, improve the stability and accuracy of intrusion detection, and solve problems such as cable aging and false triggering caused by the use of cable-based mechanical detection switches in current servers, this invention provides a server chassis intrusion detection device.

[0047] This invention provides a server chassis intrusion detection device, such as... Figure 2 As shown, it includes: an intrusion detection module 1 mounted on the top cover of the server chassis and a motherboard 2 mounted on the upper edge of the inner side wall of the server chassis; the intrusion detection module 1 and the motherboard 2 are wirelessly connected; wherein,

[0048] The intrusion detection module 1 is located on the top cover of the server chassis. It is used to collect server cover opening and closing data, bolt pressure data, and wireless power supply data. It performs logical operations on the server cover opening and closing data, bolt pressure data, and wireless power supply data to generate server cover opening and closing signal, server cover locking signal, and intrusion detection module presence signal. It then transmits these signals to the motherboard 2.

[0049] Motherboard 2 is used to receive server cover opening / closing signals, server cover locking signals, and intrusion detection module presence signals, and to perform intrusion detection on the server chassis based on these signals, generating server chassis intrusion detection results.

[0050] Specifically, when motherboard 2 detects an intrusion into the server chassis, it will display an alarm indicating that an intrusion has occurred into the server chassis.

[0051] This embodiment provides a server chassis intrusion detection device. The intrusion detection module and the motherboard are wirelessly connected, realizing cableless server chassis intrusion detection. This solves the cable aging problem caused by using cable-based mechanical detection switches. Furthermore, it detects server chassis intrusion based on server cover opening / closing signals, server cover locking signals, and intrusion detection module presence signals, thus solving the problem of false intrusion triggering. This achieves intrusion detection of the server chassis and improves the stability and accuracy of server chassis intrusion detection.

[0052] In some alternative implementations, such as Figure 3 As shown, the intrusion detection module 1 includes: a microcontroller 3, a distance sensor 4, a first pressure sensor 5, a second pressure sensor 6, a power module 7, and a first Bluetooth module 8; the microcontroller 3 is connected to the distance sensor 4, the first pressure sensor 5, the second pressure sensor 6, the power module 7, and the first Bluetooth module 8 respectively; wherein,

[0053] Distance sensor 4 is installed on the top cover of the server chassis to collect the distance between the top cover of the server chassis and the server body. Based on the distance between the top cover of the server chassis and the server body, the opening and closing data of the server cover is determined and transmitted to the microcontroller 3.

[0054] Specifically, the distance sensor 4 transmits distance changes (i.e., server cover opening and closing data) to the microcontroller 3 via I2C (Inter-Integrated Circuit) signals.

[0055] The first pressure sensor 5 is located at the first fixing bolt and is used to collect the pressure data of the first fixing bolt and transmit the pressure data of the first fixing bolt to the microcontroller 3; wherein, the first fixing bolt is located on the rear side of the server chassis cover.

[0056] Specifically, PSR1_MCU is the signal transmitted to the microcontroller 3 after the first pressure sensor 5 detects a change in pressure (i.e., the pressure data of the first fixing bolt).

[0057] The second pressure sensor 6 is located at the second fixing bolt and is used to collect the pressure data of the second fixing bolt and transmit the pressure data of the second fixing bolt to the microcontroller 3; wherein, the second fixing bolt is located on the rear side of the server chassis cover.

[0058] Specifically, PSR2_MCU is the signal transmitted to the microcontroller 3 after the second pressure sensor 6 detects a change in pressure (i.e., the pressure data of the second fixing bolt).

[0059] Furthermore, the first pressure sensor 5 and the second pressure sensor 6 are located on two bolts on the back side of the server cover, respectively, to detect whether the bolts are tightened.

[0060] The power module 7 is used to collect wireless power supply data and send the wireless power supply data to the microcontroller 3.

[0061] Specifically, MB_PWRGD is the signal that the power module 7 transmits to the microcontroller 3 after detecting a change in charging status (i.e., wireless power supply data).

[0062] The microcontroller 3 is used to perform logical operations on the hood opening and closing data to generate a server hood opening and closing signal (i.e., INT_BMC_N), perform logical operations on the pressure data of the first fixing bolt and the pressure data of the second fixing bolt to generate a server hood locking signal (i.e., LOCK_INT_BMC), perform logical operations on the wireless power supply data to generate an intrusion detection module presence signal (i.e., INT_PRSENT), and transmit the server hood opening and closing signal, the server hood locking signal, and the intrusion detection module presence signal to the motherboard 2 through the first Bluetooth module 8.

[0063] Specifically, microcontroller 3 uses an MCU (Microcontroller Unit).

[0064] Furthermore, the INT_BMC_N signal output by the microcontroller 3 is used to characterize the opening and closing status of the server cover: when the distance sensor 4 detects a distance below a fixed threshold, the microcontroller 3 reads the information from the distance sensor 4 via I2C and determines that the value of the distance sensor 4 is high. It performs an internal AND operation with the received value of MB_PWRGD and outputs INT_BMC to the motherboard 2 via the first Bluetooth module 8. When the motherboard 2 receives the INT_BMC_N signal and the result is high, it indicates that no intrusion has occurred to the server chassis and the server cover is properly closed.

[0065] Furthermore, the LOCK_INT_BMC signal output by the microcontroller 3 is used to characterize the locking status of the server cover: when the first pressure sensor 5 and the second pressure sensor 6 are subjected to a certain intensity of pressure, PSR1_MCU and PSR2_MCU will output a high level to the microcontroller 3. The microcontroller 3 internally performs an AND operation on the values ​​of these two signals and outputs the LOCK_INT_BMC signal to the motherboard 2 through the first Bluetooth module 8. When the result is a high level, it indicates that the server cover is properly locked. Specifically, when both PSR1_MCU and PSR2_MCU output by the first pressure sensor 5 and the second pressure sensor 6 are high, the LOCK_INT_BMC signal output by the microcontroller 3 is high, indicating that the server cover is properly locked.

[0066] Furthermore, the INT_PRSENT signal output by microcontroller 3 is used to characterize the presence of the intrusion detection module: in the initial state, the INT_PRSENT output by microcontroller 3 is low, indicating that the intrusion detection module is not present; the INT_PRSENT signal will be pulled high only when the INT_BMC_N output by microcontroller 3 is high, indicating that the intrusion detection module is present.

[0067] This embodiment provides a server chassis intrusion detection device. It uses a first pressure sensor and a second pressure sensor to collect bolt pressure data, thus characterizing the chassis's locking state. A distance sensor collects the opening and closing status of the chassis cover, and a power module collects wireless power supply data. A microcontroller performs logical operations on the server chassis cover opening / closing data, bolt pressure data, and wireless power supply data to generate server chassis cover opening / closing signals, server chassis cover locking signals, and intrusion detection module presence signals. This achieves accurate collection of the server chassis's opening / closing status, locking status, and power supply status, laying the foundation for comprehensive server chassis intrusion detection and improving the stability and accuracy of server chassis intrusion detection.

[0068] In some alternative implementations, the motherboard 2 includes: a second Bluetooth module 9 and a baseboard controller 10; the second Bluetooth module 9 and the baseboard controller 10 are connected; the second Bluetooth module 9 and the first Bluetooth module 8 are wirelessly connected.

[0069] The second Bluetooth module 9 is used to transmit the server cover opening / closing signal, server cover locking signal, and intrusion detection module presence signal transmitted by the first Bluetooth module 8 to the baseboard controller 10.

[0070] The baseboard controller 10 (BMC) is used to determine whether there is an intrusion into the server chassis based on the server chassis opening / closing signal, the server chassis locking signal, and the intrusion detection module presence signal, and to generate server chassis intrusion detection results.

[0071] Specifically, the baseboard controller 10 is configured to determine that an intrusion has occurred in the server chassis and issue an alarm when the intrusion detection module's presence signal is low and no server chassis opening / closing signal or server chassis locking signal is detected; when the server chassis opening / closing signal is low, the intrusion detection module's presence signal is high, and a server chassis locking signal is detected, it determines that an intrusion has occurred in the server chassis and issues an alarm; when the server chassis locking signal is low, and both the server chassis opening / closing signal and the intrusion detection module's presence signal are high, it determines that the server chassis is unlocked and issues an alarm; when the server chassis opening / closing signal, the server chassis locking signal, and the intrusion detection module's presence signal are all high, it determines that the server chassis is secure. The logic table for determining server chassis intrusion by the baseboard controller 10 is shown in Table 1 below:

[0072] Table 1:

[0073]

[0074] This embodiment provides a server chassis intrusion detection device that enables data interaction between the intrusion detection module and the motherboard through a wireless connection between the second Bluetooth module and the first Bluetooth module. This solves the problems of cable aging and false triggering caused by the use of cable-type mechanical detection switches, and improves detection efficiency by realizing intrusion detection of the server chassis through the baseboard controller.

[0075] In some alternative implementations, the motherboard 2 further includes a power supply unit (PSU) 11 and a voltage conversion module 12, wherein the power supply unit 11 is connected to the voltage conversion module 12.

[0076] Power supply 11 is used to provide external power to intrusion detection module 1 via voltage conversion module 12.

[0077] Specifically, the voltage conversion module 12 converts the power supply voltage provided by the power supply 11 into an external power supply that is compatible with the charging voltage of the wireless charging module.

[0078] This embodiment provides a server chassis intrusion detection device that uses a power supply to power the intrusion detection module, ensuring the normal operation of the intrusion detection module.

[0079] In some optional implementations, the intrusion detection module 1 further includes: a wireless charging module 13, which is connected to the power module 7 and connected to the voltage conversion module 12 via a cable;

[0080] The wireless charging module 13 is used to charge the power module 7 using the external power output from the voltage conversion module 12, so as to trigger the power module 7 to collect wireless power supply data.

[0081] Specifically, the cable is a cable, and the motherboard 2 is fixed to the upper edge of the inner side wall of the server chassis via the cable.

[0082] Furthermore, when the server cover is tightly closed, the wireless charging module 13 is in working condition. At this time, the motherboard 2 starts to supply power to the wireless charging module 13. When the power module 7 receives the external power supply, it will output the MB_PWRGD signal to the microcontroller 3. MB_PWRGD is used as an auxiliary means to characterize the closing status of the server cover.

[0083] This embodiment provides a server chassis intrusion detection device that connects a wireless charging module to a power module, thereby enabling the power module to receive power and triggering the power module to collect wireless power supply data. This lays the foundation for accurately determining the presence of the intrusion detection module in the future.

[0084] The following specific embodiment illustrates the working process of a server chassis intrusion detection device.

[0085] Example 1:

[0086] like Figure 4 As shown, the operating steps of the server chassis intrusion detection device are as follows:

[0087] ①In the initial state, the MCU outputs INT_PRSENT = 0 to the BMC, indicating that the intrusion detection module is not in place; the INT_PRSENT signal will be pulled high only when the MCU outputs INT_BMC_N high, indicating that the intrusion detection module is in place.

[0088] ② When the intrusion detection module is not in place, when the distance sensor detects a distance below a fixed threshold, the MCU reads the distance sensor information via I2C and determines that the distance sensor value is high. This determination result is then internally ANDed with the received value of MB_PWRGD, and INT_BMC is output to the BMC via the first Bluetooth module. When the BMC receives INT_MBC_N=1, it indicates that no intrusion has occurred to the chassis, the cover is properly closed, and the intrusion detection module outputs INT_PRSENT=1 to the BMC, indicating that the intrusion detection module is in place.

[0089] ③ When the intrusion detection module is in place, it determines that the server is working normally. Therefore, the cover must be in a locked state. When the first pressure sensor and the second pressure sensor are subjected to a certain pressure, PSR1_MCU and PSR2_MCU will output a high level to the MCU. The MCU internally performs an AND operation on the values ​​of these two signals and outputs the LOCK_INT_BMC signal to the BMC through the first Bluetooth module. When the BMC receives LOCK_INT=1, it indicates that the cover is properly locked. The intrusion detection module will first check the locking status of the cover. If the cover is unlocked, it will output LOCK_INT_BMC=0 to the BMC.

[0090] ④ After the cover is unlocked, the intrusion detection module will determine whether the cover has been opened. If the cover is opened, it will output INT_BMC_N=0 to BMC; if the cover is not opened, it will re-detect whether the lock has been closed.

[0091] ⑤ After the cover is opened, determine whether the cover has been open for more than 1 minute. If not, re-check the cover's latching and locking status. If it has been open for more than 1 minute, determine that the intrusion detection module is not in place and output INT_PRSENT=0 to BMC.

[0092] ⑥ If the Bluetooth connection is interrupted during the opening of the case, the second Bluetooth module on the motherboard will not receive the corresponding signal input, and all output signals will be low, indicating that the intrusion detection module is not in place.

[0093] This invention also provides a server chassis intrusion detection method, such as... Figure 5 As shown, it includes:

[0094] Step S501: The intrusion detection module collects server cover opening and closing data, bolt pressure data, and wireless power supply data. It performs logical operations on the server cover opening and closing data, bolt pressure data, and wireless power supply data to generate server cover opening and closing signal, server cover locking signal, and intrusion detection module presence signal. The intrusion detection module presence signal is then transmitted to the motherboard.

[0095] In step S501, the motherboard receives the server chassis opening / closing signal, the server chassis locking signal, and the intrusion detection module presence signal, and performs intrusion detection on the server chassis based on the server chassis opening / closing signal, the server chassis locking signal, and the intrusion detection module presence signal, and generates a server chassis intrusion detection result.
