According to the network card information protection method provided by the invention, compared with the current mode of hiding the network card icon to protect the network card information, the network card information protection method provided by the invention obtains the network card information modification instruction of the target network card, wherein the network card information modification instruction comprises the parameters to be modified corresponding to the target network card; judging whether the parameters to be modified are allowed to be modified or not based on the parameters to be modified and a preset network card information modification table, wherein each parameter of the target network card and corresponding mark information whether the parameters are allowed to be modified or not are recorded in the preset network card information modification table; if the parameter to be modified is allowed to be modified, calling a corresponding target modification function to modify the parameter to be modified; if the parameter to be modified is not allowed to be modified, feeding back prompt information that the parameter to be modified is not allowed to be modified to a user, therefore, whether the parameter to be modified is allowed to be modified or not is judged by modifying the table based on the parameter to be modified and the preset network card information, if the parameter to be modified is allowed to be modified, calling a corresponding modification function to modify the parameter to be modified, if the parameter to be modified is not allowed to be modified, the prompt information which is not allowed to be modified is fed back to the user, the condition that the user displays the hidden icon and modifies the network card information according to the displayed icon can be avoided, therefore, the network card information can be effectively protected, meanwhile, when some information of the network card needs to be modified, the process of repeatedly displaying the icons and then hiding the icons can be avoided, and a large amount of time of workers is saved.
Further, in order to better describe the above process of protecting the network card information, as a refinement and an extension to the above embodiment, an embodiment of the present invention provides another method for modifying the network card information, as shown in fig. 2, where the method includes:
201. and acquiring a network card information modification instruction of a target network card, wherein the network card information modification instruction comprises parameters to be modified corresponding to the target network card.

Specifically, the user mode may modify the parameter to be modified through ioctl or netlink system call, and before the user mode modifies the parameter to be modified through netlink system call, the modification function corresponding to each parameter in the target network card needs to be replaced by a judgment function, based on this, the method includes, because a storage location corresponding to each modification function is recorded in a preset modification function location table, based on the preset modification function location table, determining a storage location of each modification function, then acquiring each modification function at the storage location, and caching the modification function locally, and at the same time, determining a judgment function corresponding to each modification parameter in common, and calling a rtnl _ register function to register the judgment function to a corresponding location of a rtnl _ msg _ handles array, that is, storing the judgment function to the storage location, then, based on the information modification operation triggered by the user, the network card information modification instruction needs to be acquired, and based on this,step 201 specifically includes: when a system call request is detected, intercepting the system call request through a hook function arranged in a kernel, wherein the system call request comprises parameter information; judging whether the system calling request is a network card information modification instruction of the target network card or not based on parameter information in the system calling request; and if the system calling request is the network card information modification instruction, transmitting the parameters to be modified carried in the network card information modification instruction to the storage position.
Specifically, a user mode may trigger a plurality of information modification instructions at the same time, wherein the plurality of information modification instructions include not only a network card information modification instruction of the target network card, based on which, a hook function is firstly set in a kernel, when the information modification instruction of the user mode is received, a system call request is started, meanwhile, the system call request is intercepted through the hook function set in the kernel, and based on parameter information carried in the system call request, whether the system call request is the network card information modification instruction of the target network card is judged, if the system call request is the network card information modification instruction, a parameter to be modified carried in the network card information modification instruction is transmitted to the storage location, so as to judge whether the parameter to be modified is allowed to be modified by using the judgment function at the storage location, if the parameter to be modified is allowed to be modified, calling a corresponding modification function to modify the parameter, and if the parameter to be modified is not allowed to be modified, feeding back prompt information that the parameter to be modified is not allowed to be modified to a user.
202. And judging whether the parameters to be modified are allowed to be modified or not based on the parameters to be modified and a preset network card information modification table, wherein each parameter of the target network card and corresponding mark information whether the parameters are allowed to be modified or not are recorded in the preset network card information modification table.
For the embodiment of the present invention, after the parameter to be modified is transmitted to the storage location, it needs to be determined whether the parameter to be modified is allowed to be modified, and based on this, step 202 specifically includes: and judging whether the parameter to be modified is allowed to be modified or not by utilizing the judgment function at the storage position based on the parameter to be modified and a preset network card information modification table.
Specifically, since each modification function at the storage location is replaced with a judgment function, after the parameter to be modified is transmitted to the storage location, based on the parameter to be modified and a preset network card information modification table, the judgment function at the storage location is used to judge whether the parameter to be modified is allowed to be modified, and specifically, the method for judging whether the parameter to be modified is allowed to be modified by using the judgment function is as follows: matching each parameter recorded in the preset network card information modification table with the parameter to be modified by using the judgment function; and if the target parameters matched with the parameters to be modified exist in the parameters, judging whether the parameters to be modified are allowed to be modified or not based on the marking information corresponding to the target parameters.
Specifically, matching each parameter recorded in the preset network card information modification table with a parameter to be modified by using the judgment function, and judging whether a target parameter matching the parameter to be modified exists in each parameter, where the method for specifically determining the target parameter matching the parameter to be modified includes: respectively segmenting the parameters to be modified and the parameters by taking a preset character length as a unit to obtain at least one first segmentation character string corresponding to the parameters to be modified and at least one second segmentation character string corresponding to the parameters; matching the first segmented character string with the second segmented character string respectively to obtain a matching result; and determining the parameter corresponding to the second segmentation character string with the most matched characters in the matching result as the target parameter.
Specifically, with a preset character length as a unit, performing segmentation processing on the parameter to be modified to obtain at least one first segmented character string corresponding to the parameter to be modified, simultaneously, performing segmentation processing on each parameter recorded in the preset network card information modification table to obtain at least one second segmented character string corresponding to each parameter, then determining the same number of characters in the first segmented character string and each second segmented character string, determining the maximum number of characters in each number of characters, and finally determining the parameter corresponding to the maximum number of characters as the target parameter, for example, the parameter to be modified is the IP address 113.233.128.21, the parameters recorded in the preset network card information modification table include 113.356.112.21, 113.233.128.21 and 123.115.003.50, performing segmentation processing on the parameter to be modified to obtain the first segmented character string of 1/1/3/2/3/3/1/1 2/8/2/1, and meanwhile, respectively performing segmentation processing on each parameter recorded in the preset network card information modification table to respectively obtain 1/1/3/3/5/6/1/1/2/2/1, 1/1/3/2/3/3/1/2/8/2/1, 1/2/3/1/1/5/0/0/3/5/0, and respectively matching the first segmented character string with the second segmented character string to obtain a first segmented character string of 1/1/3/2/3/3/1/breast ratio 2/8/2/1 has the most characters matched with the second split character string 1/1/3/2/3/3/1/2/8/2/1, therefore, the 1/1/3/2/3/3/1/2/8/2/1 is determined as the target parameter, and then, based on the flag information indicating whether the target parameter is allowed to be modified, it is determined whether the parameter to be modified is allowed to be modified, for example, if the flag information indicating the target parameter is "NO", determining that the parameter to be modified is not allowed to be modified, and if the marking information corresponding to the target parameter is "YES", determining that the parameter to be modified is allowed to be modified.

For the embodiment of the present invention, if the parameter to be modified is allowed to be modified, the cache position corresponding to the target modification function is determined, the function obtaining interface corresponding to the target modification function is determined, and the target modification function at the cache position is called to modify the parameter to be modified based on the function obtaining interface.
204. And calling the target modification function to modify the parameter to be modified based on the function interface.
For the embodiment of the invention, after the function acquisition interface corresponding to the target modification function is determined, the target modification function is called in the function acquisition interface to modify the parameter to be modified.
205. And if the parameter to be modified is not allowed to be modified, feeding back prompt information that the parameter to be modified is not allowed to be modified.
For the embodiment of the present invention, if the parameter to be modified is not allowed to be modified, a modification prohibition instruction that the parameter to be modified is not allowed to be modified is generated, based on the modification prohibition instruction, the function acquisition interface is closed, that is, the acquisition path of the target modification function is blocked, and a prompt message that the parameter to be modified is not allowed to be modified is generated, where the prompt message may be a text word such as "modification is not allowed" or other prohibition identifiers.
