In an embodiment of the present invention, fig. 2 is a schematic flow chart illustrating an implementation process of an apparatus linkage method according to an embodiment of the present invention. As shown in fig. 2, the apparatus linkage method may include the steps of:

step 201, each terminal device obtains all pre-configured management policies in the network management device.

In the specific embodiment of the present invention, when each terminal device is linked with the network management device, each terminal device may first obtain all the pre-configured management policies from the network management device. Specifically, in a specific embodiment of the present invention, the terminal device may be: pc (personal computer) with security management system installed in advance; the network management device may be: a network device of an Internet Control Gateway (ICG) is pre-installed.

Preferably, in the embodiment of the present invention, before each terminal device obtains all the pre-configured management policies in the network management device, each terminal device may obtain a pre-developed plug-in program in the network management device through a pre-installed security management system, and each terminal device obtains all the management policies in the network management device through the security management system and the plug-in program. Specifically, in the specific embodiment of the present invention, each terminal device and the network management device may first specify an interface rule, then the network management device may issue a COM component or a dynamic link library to each terminal device, each terminal device loads the received COM component or dynamic link library, and each terminal device obtains all management policies in the network management device through the COM component or dynamic link library. In the existing terminal device, a plug-in (Extension) is also called an Extension, and is a program written in an application program interface conforming to a certain specification, and is mainly used for extending software functions. Many software have plug-ins, some of which are developed by the software company itself, and some of which are developed by third parties or by individuals of software users. Specifically, in the specific embodiment of the present invention, after each terminal device may obtain a pre-developed plug-in the network management device, each terminal device may load the plug-in first, and then obtain all management policies in the network management device through the security management system and the plug-in.

Fig. 3 is a flowchart illustrating an implementation method for each terminal device to obtain all management policies in the embodiment of the present invention. As shown in fig. 3, the method for each terminal device to obtain all pre-configured management policies in the network management device may include the following steps:

step 201a, each terminal device sends a request message to a network management device according to a preset period; wherein, each request message carries the terminal device identification of each terminal device.

In the specific embodiment of the present invention, when each terminal device obtains all the pre-configured management policies in the network management device, each terminal device may send a request message to the network management device according to a pre-cycle; wherein, each request message carries the terminal device identification of each terminal device. Specifically, in the specific embodiment of the present invention, each terminal device may send a request message to the network management device through the security management system and the plug-in program according to a preset period. Fig. 4 is a schematic diagram of a linkage network of the terminal device and the network management device in the embodiment of the present invention. As shown in fig. 4, each PC can send a request message to the network management apparatus every 30 seconds through the security management system and the plug-in. Specifically, each PC can send a request message to a pre-configured router every 30 seconds through a security management system and a plug-in, and the router forwards the request message to the network management device; wherein, each request message carries the IP address of each PC.

Step 201b, the network management device issues all network management strategies to each terminal device according to each terminal device identifier.

In the specific embodiment of the present invention, after the network management device receives the request message carrying the terminal device identifier sent by each terminal device, the network management device may issue all network management policies to each terminal device according to the terminal device identifier carried in each request message. As shown in fig. 4, after the network management device receives the request message carrying the IP address sent by each PC, the network management device may issue all network management policies to each PC according to the IP address carried in each request message. Specifically, the network management device may issue all the management policies to the router, and the router forwards all the management policies to each terminal device.

Step 201c, each terminal device receives all management policies issued by the network management device.

In the specific embodiment of the present invention, after the network management device issues all the network management policies to each terminal device, each terminal device may receive all the management policies issued by the network management device. For example, after the network management device issues the entire management policy to the PC with IP address 211.138.157.181, the PC with IP address 211.138.157.181 receives the entire management policy issued by the network management device.

As can be seen from the above analysis, in thesteps 201a to 201c, each terminal device may obtain all the pre-configured management policies from the network management device, and then each terminal device may determine the corresponding target management policy from all the network management policies, so that each terminal device and the network management device may be linked according to the target management policy.

Step 202, each terminal device determines a corresponding target management policy in all management policies.

In the specific embodiment of the present invention, after each terminal device acquires all the pre-configured management policies in the network management device, each terminal device may determine the corresponding target management policy in all the management policies. Fig. 5 is a flowchart illustrating an implementation method for determining a target management policy corresponding to each terminal device in the embodiment of the present invention. As shown in fig. 5, the method for determining the target management policy corresponding to each terminal device in the total management policies includes the following steps:

step 202a, each terminal device obtains the corresponding terminal device information through the security management system and the plug-in program.

In a specific embodiment of the present invention, after each terminal device obtains all the preconfigured management policies in the network management device, each terminal device may obtain the corresponding terminal device information through the security management system and the plug-in. Specifically, in a specific embodiment of the present invention, the terminal device information may be one or more pieces of information related to the terminal device. For example, each terminal device may obtain a corresponding operating system type through the security management system and the plug-in program; or, each terminal device may obtain the corresponding operating system type and IP address through the security management system and the plug-in program.

Step 202b, each terminal device determines a corresponding target management policy in all management policies according to the corresponding terminal device information.

Specifically, managingpolicy 1 may include:terminal device information 1 andconstraint condition 1; management policy 2 may include: terminal device information 2 and constraint conditions 2; …, respectively; the terminal information M may include: terminal equipment information M and constraint conditions M; wherein M is a natural number of 1 or more. Specifically, the correspondence between the terminal device information and the constraint condition may be as shown in table 1 below:

managing policies	Terminal device information	Constraintconditions
			Management policy
1	Terminal device information 1	Constraint 1
			Management policy 2	Terminal device information 2	Constraint 2
…	…	…
			Management policy M	Terminal device information M	Constraint M

TABLE 1

In table 1 above,terminal device information 1 corresponds toconstraint condition 1; the terminal device information 2 corresponds to the constraint condition 2; …, respectively; the terminal device information M corresponds to the constraint condition M. Specifically, in the specific embodiment of the present invention, each piece of terminal device information may correspond to one constraint condition, or may correspond to a plurality of constraint conditions. Therefore, after each terminal device obtains the corresponding terminal device information through the security management system and the plug-in program, each terminal device may determine the corresponding target management policy in all management policies according to the corresponding target terminal information. For example, the terminal device N may determine a target management policy N corresponding to the terminal device N in all management policies according to the terminal device information N corresponding to the terminal device N; wherein, the target management policy N comprises: terminal device information N and constraint condition N; n is a natural number of 1 or more and M or less.

Fig. 6 is a flowchart illustrating an implementation method for determining a target management policy by each terminal device according to terminal device information in the embodiment of the present invention. As shown in fig. 6, the method for determining the target management policy corresponding to each terminal device in the total management policies according to the terminal device information corresponding to each terminal device may include the following steps:

instep 202b _1, each terminal device matches the corresponding terminal device information with all management policies.

In the specific embodiment of the present invention, after each terminal device obtains all the pre-configured management policies in the network management device through the security management system and the plug-in, each terminal device may match the corresponding terminal device information with all the management policies. Specifically, theterminal device information 1 may be successfully matched with themanagement policy 1; the terminal device information 2 can be successfully matched with the management strategy 2; …, respectively; the terminal device information M may be successfully matched with the management policy M. It should be noted that, in the specific embodiment of the present invention, each piece of terminal device information may be successfully matched with one of all management policies; or can be successfully matched with a plurality of management policies in the whole management policies. For example,terminal device information 1 may be successfully matched withmanagement policy 1; theterminal device information 1 may also be successfully matched with themanagement policy 1 and the management policy 2.

Step 202b _2, each terminal device judges whether the corresponding terminal device information is successfully matched with at least one management strategy; if yes, go to step 202b _ 3; otherwise,step 202b _4 is performed.

In the specific embodiment of the invention, each terminal device judges whether the information of the corresponding terminal device is successfully matched with at least one management strategy; when each terminal device determines that the matching between the corresponding terminal device information and the at least one management policy is successful, executingstep 202b _ 3; when each terminal device determines that each piece of corresponding terminal device information fails to match each management policy,step 202b _4 is performed.

And step 202b _3, each terminal device determines the successfully matched management policy as a target management policy.

In the specific embodiment of the present invention, when each terminal device determines that the matching between the corresponding terminal device information and at least one management policy is successful, each terminal device determines the successfully matched management policy as the target management policy. Specifically, each piece of terminal device information may be successfully matched with one of the management policies in all the management policies; or can be successfully matched with a plurality of management policies in the whole management policies. When each terminal device determines that the matching between the corresponding terminal device information and one management policy is successful, each terminal device can determine the management policy as a target management policy; when each terminal device determines that the matching between the corresponding terminal device information and the plurality of management policies is successful, each terminal device may determine all the successfully matched management policies as the target management policies.

And step 202b _4, each terminal device finishes the linkage process with the network management device.

In the specific embodiment of the present invention, when each terminal device determines that each piece of corresponding terminal device information fails to match each piece of management policy, each terminal device ends the linkage process with the network management device.

As can be seen from the above description, through thesteps 202b _1 to 202b _4, each terminal device may determine a corresponding target management policy in all management policies according to the corresponding terminal device information, and then each terminal device may be linked with the network management device according to the target management policy corresponding to each terminal device.

And step 203, linking each terminal device with the network management device according to the target management strategy corresponding to each terminal device.

In a specific embodiment of the present invention, after each terminal device determines a corresponding target management policy in all management policies, each terminal device may be linked with the network management device according to the target management policy corresponding to each terminal device. Specifically, after each PC determines a corresponding target management policy among all management policies, each PC may be linked with the network management device according to the target management policy corresponding to each PC. For example, if the target management policy corresponding to the PC1 is "network blocking", the network management device will perform network blocking on thePC 1.

Preferably, in the embodiment of the present invention, each terminal device may further determine a corresponding user management policy, and each terminal device and the network management device perform linkage according to the target management policy and the user management policy corresponding to each terminal device.
