Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. In addition, in the embodiments of the present application, "first", "second", etc. are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence.
The embodiment of the application discloses a network card detection method, which improves the applicability of the detection of a specified type of network card.
Referring to fig. 1, a flowchart of a network card detection method according to an exemplary embodiment is shown, as shown in fig. 1, including:
S101: acquiring an IP address corresponding to the target equipment;
The execution subject of the embodiment is a detection device, and a network connection exists between the detection device and a detected target device. For example, the detection device may be deployed in an internal network where the target device is located. As shown in fig. 2, the intra-organization network includes detected target devices PC1, PC2, … PCn and detection devices, and the detection devices detect the PC1, PC2, … PCn to obtain network card information of the PC1, PC2, … PCn, respectively.
It should be noted that, the detection device in this embodiment may be a deployed terminal device connected to the target device through a network, that is, the network card detection method in this embodiment may be implemented by multiplexing the deployed terminal device, or a detection device dedicated to network card detection may be redeployed, which is not limited herein.
In a specific implementation, a user inputs one of the IP addresses of the target device through the input interface, and the detection device performs network card detection on the IP address corresponding to the target device after obtaining the IP address, that is, judges whether the target device includes a network card of a target type. The network cards of the target type in this embodiment may include a wireless network card, a mobile network card, and the like, and a mobile network card, for example, a 3G network card, a 4G network card, a 5G network card, and the like.
S102: sending a service request message to the IP address to acquire a service list of the target equipment;
In a specific implementation, the detection device sends a service request to an IP address of the target device, and receives a corresponding response message, where the response message includes a service list of the target device. It can be understood that if the corresponding response message is not received by sending the detection message once, the detection message can be continuously sent for multiple times until the corresponding response message is received or the sending times reach a preset value.
In a specific implementation, a service request message is sent to the acquired IP address, where the service request message is used to acquire a service list of the target device, and may be specifically a DEC/RPC service request message. DCE/RPC (DECRemoteProcedureCallProtocol) is a standard remote procedure call protocol framework, and DCE/RPC runs independently on top of the network transport layer protocol to support applications in the system to seamlessly invoke procedures in service processes on remote hosts over the network. Further, the received response message is analyzed to obtain a service list of the target device.
S103: and determining the type of the network card started by the target equipment based on the service list.
In this step, for the obtained service list of the target device, it may be determined whether there is a service corresponding to the network card of the target type, and accordingly, whether the target device includes the network card of the target type is determined, that is, this step may include: judging whether a service corresponding to the network card of the target type exists in the service list; if yes, judging that the target equipment is using the network card of the target type. Further, a record of the network card being used by the target device may also be stored in a local file system or database.
If WLAN SERVICE exists in the service list, the wireless network card indicates that the target device is using the wireless network card. For the mobile network card, if WWAN SERVICE exists in the service list, it indicates that the target device is using the mobile network card.
For example, as shown in fig. 3, the IP address of the detected device is 10.130.10.191, the device includes three network cards, which are respectively an ethernet network card, a wireless network card and a mobile network card, the detection items are configured as a wireless network card and a 4G network card, the network card detection result is shown in fig. 4, and the device has both a wireless network card and a mobile network card.
According to the network card detection method provided by the embodiment of the application, the detection equipment sends the service request message to the target equipment based on the network connection with the target equipment, and determines whether the target equipment contains the network card of the target type according to the received service list. Therefore, in the embodiment of the application, the detection equipment can determine whether the target equipment contains the network card of the target type only by the network connection with the detected target equipment, so that the detection of the network card of the specified type without end is realized, and the detection applicability of the network card of the specified type is higher.
An application scenario of the network card detection method provided by the present application, that is, an illegal external connection detection scenario, is described below, as shown in fig. 5 and fig. 6, the company organization accesses internal network resources by default through a wired network, if a device accesses a wireless network card or a mobile network card, and accesses other networks outside the internal network through the wireless network card or the mobile network card. The method for accessing other networks by using the wireless network card or the mobile network card can leak the internal data of the company under the condition that the network flow is not monitored and audited. Therefore, the inspection device needs to detect a device that is using a wireless network card or a mobile network card.
In the following, an application scenario of the network card detection method provided by the application, namely an access scenario of illegal network equipment is introduced, as shown in fig. 7, a Wi-Fi hotspot is set by a certain computer in a company organization through a wireless network card, and other illegal network equipment can access to a network in the company through the hotspot, so that certain security access audit of the internal network can be avoided, and the internal network security is threatened. Therefore, the inspection device needs to detect a device that is using a wireless network card or a mobile network card.
