The reparation relevant information of leak to be repaired is compiled in terminal device.
For this step, in a kind of application scenarios, terminal device manufacturer, directly will safety before terminal device is released
The service packs carry that software vendor provides is in system kernel, i.e.,：Before user's using terminal equipment, hung in terminal device
Service packs is carried.In another application scenarios, terminal device manufacturer is after terminal device is released, and terminal device is from server
Middle acquisition service packs, and by the service packs carry system kernel.
For second of application scenarios, embodiment can be corresponding to this step：Terminal device is sent out to server
Send and inquire about the request that the terminal device corresponds to service packs, can specifically set and send the cycle, looked into for example, setting and sending 1 time for every 3 days
Request is ask, after server determines service packs corresponding to the existing equipment, corresponding feedback information is sent to the terminal and set
It is standby, after terminal device receives the feedback information, corresponding service packs is downloaded from server immediately, and carry is in the kernel of system
In.In another embodiment, after server determines to have service packs corresponding to the equipment, actively service packs is issued to
Corresponding terminal device, terminal device is after the service packs is received, by the service packs carry in the kernel of system.
The process of the carry service packs in kernel is illustrated below by one embodiment, but is said with being also only exemplary
It is bright, it is impossible to be interpreted as limitation of the invention.
Specifically, as shown in Fig. 2 terminal device includes user's space (User Space) and kernel spacing
(Kernel) it, may include SDK (Software Development Kit, i.e. SDK) in user's space, and
Local finger daemon (Native Daemon).Wherein, Native Daemon are executable program, for example, init processes, are being
System starts when starting, and is responsible for being communicated with kernel, service packs is carried out the work such as to verify；SDK is responsible for being led to server
News.
The process of system kernel carry service packs is described in detail with reference to Fig. 2：
Compiled service packs is sent to server corresponding to terminal device manufacturer and (set by server corresponding to fail-safe software
Standby server), terminal device sends the request inquired about the terminal device and correspond to service packs to server by SDK, specifically looks into
Ask in server and whether there is service packs corresponding to the terminal device, after device server receives the request, returned to the SDK
Feedback information；If the feedback information is determines service packs corresponding to terminal device be present in server, the SDK is according to the feedback letter
Cease, download corresponding service packs in slave unit server, and the service packs is sent to Native Daemon；Native
After Daemon receives the service packs, to the service packs carry out signature check, specifically verify the service packs sender whether be
The server (destination server) made an appointment, when it is determined that sender is destination server, the service packs is sent to kernel,
The carry of service packs is completed i.e. in kernel.
S102：Leak reparation is carried out according to the service packs.In this step, the service packs in kernel leaks to system
Hole is repaired, and the mode specifically repaired includes：Object function is repaired by Hook Function (HOOK), with completion pair
The reparation of system kernel leak.Specifically, by arranging HOOK programs in service packs, the HOOK programs are responsible for pre- in kernel
The call function first configured is monitored, and when HOOK monitors problem function (object function), hooks up problem function and timely
Ground is repaired to the object function, is finally completed the leak reparation of whole system kernel.In a preferred embodiment,
It is atomic operation by HOOK process optimizations, so, system will not be impacted when leak is repaired.
The mode of system vulnerability reparation is also included：When detecting the presence of the abnormal document of leak, by the abnormal document
Corresponding whole file replaces with the whole file after renewal, to complete the reparation to system vulnerability.Specifically, server enters to system
During row detection, file corresponding to system vulnerability (abnormal document) is determined, and the abnormal document is repaired, after being updated
Whole file；Whole file write-in service packs after this is updated, when terminal device is repaired using the service packs to system vulnerability
When, whole file corresponding to abnormal document is directly replaced with into the whole file after renewal.Repaired by way of whole file replacement and be
System leak, ensure that the stability of system.
The whole file that the mode that above-mentioned whole file is replaced can be regarded as in certain memory range is replaced, if abnormal document pair
The internal memory shared by complete file answered is larger, so, if the complete file is replaced, will necessarily consume substantial amounts of
Resource, therefore, in the embodiment of the present invention, the file that can intercept certain memory range is used as " whole file ".
The embodiment of the present invention also includes：After system vulnerability repaired by kernel, result will be repaired and sent to server,
So that each patch that server is included according to reparation result to service packs is debugged.In actual applications, when system is leaked
After hole is repaired, terminal device will repair result and first send to terminal device service device, and terminal device service device can be to repairing
As a result filtered, for example, the information of some terminal devices is filtered out, such as, use or the number for buying the terminal device, so
Afterwards, the reparation result after filtering is sent to the information security that to fail-safe software server, ensure that terminal device manufacturer.
In actual applications, system vulnerability once can not possibly be detected with regard to whole, but in the mistake for using or detecting
Constantly it is detected in journey, therefore, it is necessary to constantly compiles out patch corresponding to each leak for the leak newly detected.Such as
The content that background technology is recorded, in the prior art, terminal device manufacturer periodically can be repaired or be upgraded to system, but
Because the reparation or upgrading of every subsystem can expend substantial amounts of resource, therefore, terminal device will not set shorter repairing efficiency,
So, system vulnerability is caused to be repaired in time.In addition, with the development of science and technology, the renewal of terminal device is very rapid,
Most of terminal device manufacturer only repairs within a period of time to the system of certain equipment, just no longer repairs afterwards, at this moment
To still using this equipment user with inconvenience.
In view of the above-mentioned problems, providing a kind of embodiment, the embodiment is specially the embodiment of the present invention：To server
