Fig. 1 is a flowchart of a self-checking method for an internet of things terminal according to an embodiment of the present invention, which is applicable to a situation of performing security self-checking on an electric power internet of things terminal.
As shown in fig. 1, the self-checking method for the internet of things terminal provided by this embodiment specifically includes:
s110, collecting current operation system parameters of the terminal of the Internet of things at regular time, and comparing the current operation system parameters with the initial operation system parameters according to a target logic comparison strategy.
The internet of things terminal can be an electric power internet of things terminal, for example, an electric power fault positioning device, a smart meter, a temperature sensor and the like. In the electric power internet of things industry, the number of the internet of things terminals is very large, the types of the internet of things terminals are also diversified, and the type of the internet of things terminals is not particularly limited in the embodiment.
The current operation system parameters refer to system parameters of the internet of things terminal when the internet of things terminal operates at the current moment; the initial operation system parameters refer to system parameters of the internet of things terminal during initial operation, and the initial operation specifically refers to that the internet of things terminal is just put into operation.
Optionally, the system parameter includes at least one of: the method comprises the following steps of process quantity, process type, processor performance state, memory performance state, data storage area state, parameter storage area state, port state and inherent function parameter value.
The process number refers to the number of processes operated by the terminal of the internet of things; the process type refers to the type of a process operated by the terminal of the Internet of things; the processor performance state refers to state information used for describing the performance of a processor (such as a CPU) of the terminal of the internet of things, such as utilization rate and the like; the memory performance state refers to state information used for describing the memory performance of the internet of things terminal, such as memory usage amount, memory usage rate and the like; the data storage area state refers to the state of a storage area for storing data detected and collected by the terminal of the internet of things, and comprises a stored data amount, a stored data type, a stored data value and the like; the parameter storage area state refers to the state of a storage area for storing the parameters set by the terminal of the internet of things, and comprises a storage data volume, a storage data type, a storage data value and the like; the port state refers to information used for describing a port working state of the terminal of the internet of things, such as opening, closing, receiving data, sending data and the like, and the port can be a serial port, a network port and the like; the intrinsic function parameter value refers to a parameter value related to an intrinsic function of the terminal of the internet of things, for example, the intrinsic function of the power failure positioning device is a failure positioning function, the intrinsic function of the smart meter is measuring electric quantity, and the intrinsic function of the temperature sensor is measuring temperature.
The terminal of the internet of things acquires the current operating system parameters at regular time, for example, the current operating system parameters may be acquired at regular time according to a self-checking period, the duration of the self-checking period may be two hours, and the current operating system parameters may be specifically timed through a built-in timer module of the terminal of the internet of things. The system parameters acquired by the terminal of the internet of things at regular time can be preset system parameters related to the equipment, and the types of the parameters related to the current operation system parameters acquired at regular time are matched with the types of the parameters related to the initial operation system parameters.
The target logic comparison strategy refers to a logic comparison strategy matched with the terminal of the Internet of things. The logic comparison strategies corresponding to different types of terminals of the internet of things can be consistent or have individual differences. The target logic comparison strategy may be pre-stored in the terminal of the internet of things.
Optionally, the logic comparison policy at least includes a comparison order of different types of system parameters, and a mapping relationship between each comparison result and a system exception problem. For example, in the target logic comparison strategy, firstly, the number of processes is compared, then, the types of the processes are compared, and if the number of the processes and the types of the processes are not abnormal, then, the other system parameters are compared; for another example, in the target logic comparison policy, the number of processes is compared first, and if the number of processes is abnormal, the process type is compared to determine the abnormal process.
It should be noted that, for different types of system parameters, the mapping relationship between the comparison result and the system abnormal problem may be different, and may be specifically set according to the type of the system parameter, which is not specifically limited in this embodiment. For example, for the number of processes, the mapping relationship between the comparison result and the system exception problem may be that when the number of currently running processes is larger than the number of initially running processes by a preset percentage threshold, it is determined that the number of processes is abnormal. For another example, for the port state, when the working state of the current running port is inconsistent with the working state of the initial running port, it is determined that the port state is abnormal. For another example, for a process type, the mapping relationship between the comparison result and the system exception problem may be that the process type of a running process does not belong to the process type involved in the initial running system parameters, and it is determined that the process type is abnormal.
It should be noted that, in the logic comparison policy, it may be set whether to continue to compare other system parameters in sequence if it is determined that the networked terminal system is abnormal according to the comparison result of some system parameter, which is not specifically limited in this embodiment.
As an optional implementation manner, before comparing the current operating system parameter with the initial operating system parameter according to the target logic comparison policy, the method further includes:
receiving and storing the target logic comparison strategy; wherein the target logic comparison policy is determined based on a system parameter comparison logic generation request and a general logic comparison policy.
The general logic comparison strategy is a logic comparison strategy which is determined by system parameters based on the general use of the Internet of things terminals and is suitable for carrying out security self-check on most Internet of things terminals.
The system parameter comparison logic generation request refers to an application request initiated by a user and is used for indicating generation of a target logic comparison strategy corresponding to the security self-check of the terminal of the internet of things, wherein the system parameter comparison logic generation request can carry special system parameters of the terminal of the internet of things, a comparison sequence of the special system parameters, a mapping relation between a comparison result and a system abnormal problem and the like.
Illustratively, the system parameter comparison logic generation request may be initiated in the internet of things terminal monitoring background, the target logic comparison policy is generated by the internet of things monitoring background based on the system parameter comparison logic generation request and the general logic comparison policy, and the target logic comparison policy is issued to the matched internet of things terminal, so that the internet of things terminal can compare the currently running system parameter with the initially running system parameter at regular time according to the target logic comparison policy.
When the internet of things terminal does not relate to other special system parameters except the general system parameters, the general logic comparison strategy can be taken as a target logic comparison strategy to be issued to the matched internet of things terminal through the internet of things monitoring background, so that the internet of things terminal can compare the current operating system parameters with the initial operating system parameters at regular time according to the target logic comparison strategy.
Optionally, when the terminal of the internet of things is put into operation, the current operation system parameters of the terminal of the internet of things are recorded as the initial operation system parameters. The initial operation system parameters can be stored in an independent storage area of the terminal of the Internet of things.
It is worth pointing out that the current operating system parameters recorded by the terminal of the internet of things may be the system parameters involved in the target logic comparison policy.
Further, if an initial operating system parameter modification request is received, updating the initial operating system parameters according to the initial operating system parameter modification request.
The initial operating system parameter modification request refers to a request for indicating modification of an initial operating system parameter. Optionally, the initial operating system parameter modification request carries the type of the system parameter to be modified and a parameter value.
And after the terminal of the Internet of things receives the initial operation system parameter modification request, correspondingly modifying the stored initial operation system parameters according to the indication of the initial operation system parameter modification request.
It should be noted that administrator privileges may be set with respect to modification of initial operating system parameters, with respect to modification of duration of self-test cycles. That is, only the administrator can modify the initial operating system parameters, the duration of the self-test period, and the like.
And S120, if the Internet of things terminal system is determined to be abnormal according to the comparison result, performing system abnormal recovery on the Internet of things terminal.
When the current operation system parameters are compared with the initial operation system parameters according to the target logic comparison strategy, if the current operation system parameters and the initial operation system parameters meet consistency conditions, it is determined that no system abnormality exists in the terminal of the Internet of things, and then the current operation system parameters and the initial operation system parameters can be compared again according to the target logic comparison strategy when the next self-checking period is reached.
The consistency condition refers to that the current operating system parameter is completely the same as the initial operating system parameter, or the difference between the current operating system parameter and the initial operating system parameter is within a preset threshold range.
When the current operation system parameters are compared with the initial operation system parameters according to the target logic comparison strategy, if the system parameters which do not meet the consistency condition exist, the abnormality of the terminal system of the Internet of things is determined, meanwhile, the system abnormality problem of the terminal of the Internet of things can be positioned according to the mapping relation between the comparison result and the system abnormality problem, and then the system abnormality problem can be solved through the recovery process so as to recover the system abnormality of the terminal of the Internet of things.
For example, if the system exception problem is that a process type exception exists, the process with the process type exception can be closed by recovering the process; for another example, the system exception problem is a port state exception, and if the working state of a certain port in the initially running system parameters is off and the working state of a certain port in the currently running system parameters is on, the port can be closed through the recovery process, so that the working adjustment of the port is recovered to be closed.
Further, if the abnormal duration of the terminal system of the internet of things reaches a duration threshold, performing system initialization on the terminal of the internet of things; and/or after the system of the terminal of the internet of things is recovered, if the system is failed to recover and the current recovery times of the system reach a time threshold value, performing system initialization on the terminal of the internet of things.
When the terminal system of the internet of things is determined to be abnormal according to the comparison result, counting the abnormal duration of the terminal system of the internet of things, and if the abnormal duration of the system reaches a duration threshold value, such as several minutes, dozens of minutes and the like, performing system initialization on the terminal of the internet of things, namely performing system restart on the terminal of the internet of things, so that the terminal of the internet of things is restored to an initial operation state.
The method comprises the steps of setting matched duration thresholds aiming at different system abnormity problems, counting abnormal duration of the terminal system of the Internet of things when the abnormal terminal system of the Internet of things is determined according to a comparison result, determining the duration threshold matched with the current system abnormity problem, and carrying out system initialization on the terminal of the Internet of things if the duration of the current system abnormity problem reaches the matched duration threshold.
And when the terminal system of the Internet of things is determined to be abnormal, performing system abnormal recovery on the terminal of the Internet of things, wherein the result of the system abnormal recovery may be recovery success or recovery failure. If the recovery is successful, comparing the current operating system parameter with the initial operating system parameter again according to the target logic comparison strategy until the next self-checking period is reached. If the recovery fails, the abnormal recovery of the system can be continuously carried out on the terminal of the Internet of things, and meanwhile, the current recovery times of the system are counted. And when the current recovery frequency of the system reaches a preset frequency threshold value, performing system initialization on the terminal of the Internet of things, namely performing system restart on the terminal of the Internet of things so as to recover the terminal of the Internet of things to an initial operation state.
Further, before the system initialization is performed on the terminal of the internet of things, the target function of the terminal of the internet of things can be closed, and fault reporting information is sent to the terminal monitoring background of the internet of things.
The target function refers to an inherent function that is suspected to affect the security of the terminal of the internet of things, and may be, for example, a process running function, a port data receiving and sending function, and the like.
Before the system initialization is carried out on the terminal of the Internet of things, the target function of the terminal of the Internet of things is closed so as to reduce the safety risk of the terminal of the Internet of things as much as possible.
Meanwhile, before the system initialization is carried out on the terminal of the internet of things, fault reporting information can be sent to the terminal monitoring background of the internet of things so as to report the current system abnormal problem of the terminal of the internet of things. The fault reporting information may include an equipment identifier of the internet of things terminal, a code of a system abnormal problem, and the like. Optionally, a fault reporting port of the internet of things terminal is opened, and fault reporting information is sent to the internet of things terminal monitoring background through the fault reporting port.
According to the technical scheme provided by the embodiment of the invention, the terminal of the Internet of things regularly acquires the parameters of the current operation system, compares the parameters of the current operation system with the parameters of the initial operation system according to the target logic comparison strategy, and performs system abnormity recovery on the terminal of the Internet of things if the abnormality of the terminal system of the Internet of things is determined according to the comparison result, so that the automatic safety detection of the terminal of the Internet of things is realized, and the system abnormity recovery is performed on the terminal of the Internet of things when the terminal system of the Internet of things is abnormal, thereby reducing the risk of tampering the parameters of the terminal system of.
According to the technical scheme provided by the embodiment of the invention, the function supplement of the terminal watchdog is realized, the problem of system abnormity of the terminal of the Internet of things can be positioned through safety self-detection, the system abnormity recovery of the terminal of the Internet of things can be carried out, and the risk of tampering the system parameters of the terminal of the Internet of things and the safety risk brought by an abnormal process in the operation process are reduced.
