Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment one
Present embodiment comprises that with service end the two-stage client that echelon connects is that example describes the utility model.
Like Fig. 1~shown in Figure 2, attack protection safety interaction system mainly comprises a service end, and a L 1 customer end that is connected with this service end, and this L 1 customer end is divided into three secondary clients, and each secondary client is divided into two subscriber's main stations.Wherein, said service end is embedded with system management module, abnormality processing module, protocol process module and data storage, and L 1 customer end and secondary client all are embedded with the instruction Executive Module.The implementation method of this system is following:
One. service end realizes unified management to all clients
1. client registration: for realizing management to client; Service end is regularly sent scan instruction by system management module; And utilize protocol process module to transfer to clients at different levels; All clients in its lower floor's network scan, and upgrade client-side information, as upgrading the client terminal quantity that is connected with service end; After the instruction Executive Module of L 1 customer end receives scan instruction, when oneself is carried out scan operation, send this scan instruction to all secondary clients.Whether all clients detect self and in the system management module of service end, register after receiving scan instruction, if register, then scan instruction finishes, otherwise, then send register requirement, and transmit the close spoon of session at random to system management module; After system management module receives register requirement, client is registered, and beamed back the affirmation information of registration to client.
2. subscriber's main station registration: the instruction Executive Module by client is passed the MAC Address of its all subscriber's main stations of lower floor back service end through protocol process module, and is stored in the data storage.
3. whether all subscriber's main stations are online in the affirmation network: subscriber's main station regularly sends heartbeat packet to the system management module of service end, and with it accordingly, system management module makes regular check on whether receive heartbeat packet; If receive, the Counter Value that then upgrades the subscriber's main station corresponding with this heartbeat packet is predefined maximum, otherwise the Counter Value of the subscriber's main station corresponding with this heartbeat packet subtracts 1; If the Counter Value of subscriber's main station is 0, then the state of this subscriber's main station of service end record is an off-line.The Counter Value of subscriber's main station and its MAC Address direct correlation, and be stored in the data storage.
In the present embodiment; The counter maximum of predefined subscriber's main station is 3; If promptly continuous three service ends are not all received the heartbeat packet from certain subscriber's main station, service end is thought this subscriber's main station off-line so, and service end is carried out record to the state of this subscriber's main station.
4. the client-side information configuration is formulated with security strategy: the system management module of service end is formulated configuration information and security strategy according to the last state of client and subscriber's main station; And it is sent to all clients through protocol process module, accomplish the automatic configuration of client-side information.In addition, the information configuration work of client also can be by configuration manually in the utility model.
So far, service end is accomplished the unified management to all clients through protocol process module, for service end initiatively defends to have laid attainable basis with attack.
Two. service end is to the active defence and attack of subscriber's main station
Service end is passed through the source that the abnormality processing module analysis is also confirmed the attack data, and to client transmit operation instruction, by the instruction Executive Module execution of client the active of subscriber's main station is defendd and attack.
1. confirm the attack source
System management module preestablishes the standard of normal data in the network, and this standard comprises standard and the built-in intrusion feature database of system management module that subscriber's main station is set; Client is back to the abnormality processing module with the real data that receives through protocol process module, by the abnormality processing module it and predefined standard is compared, and judges whether it is unusual; If confirm this data exception, system management module is traced the transmission link of this abnormal data at once, and will it with data storage in the MAC Address of the subscriber's main station that writes down compare, thereby the source of definite this abnormal data.
As shown in Figure 2, confirm in the present embodiment that the attack source is from a subscriber's main station in the undernet of a secondary client.
2. service end is carried out the active defence to the attack source and is attacked
After system management module is confirmed the attack source, send the punishment instruction, and through transferring to and the direct-connected secondary client in this attack source behind the L 1 customer end, this punishment refers to include the filtering instructions of filtering object by the abnormality processing module; The instruction Executive Module of this secondary client filters according to the data that the filtering instructions that receives sends this attack source, up to meeting this secondary client current security strategy; After filtering data was up to standard, this instruction Executive Module was back to the abnormality processing module with filtered data through the L 1 customer end, and the abnormality processing module is analyzed these data once more; If these data belong to normal data; Then guarantee the normal transmission of these data, otherwise, then send the blocking-up instruction to this secondary client through the L 1 customer end; The network that breaks off this attack source according to the blocking-up instruction by its instruction Executive Module connects; Thereby cut off its transmission path, attack data service end is attacked, realize the initiatively purpose of defence capability of service end to prevent its transmission.On the other hand, service end realizes data filter, the attended operation of disconnection network to the attack source through under the secondary client, sending instructions, and promptly is one of active attack mode to this attack source, has improved the ability of service end active attack to a certain extent.
Embodiment two
Like Fig. 1, shown in Figure 3, attack protection safety interaction system mainly comprises a service end, and three L 1 customer ends that are connected with this service end, and each L 1 customer end is divided into two subscriber's main stations.Wherein, said service end is embedded with system management module, abnormality processing module, protocol process module and data storage, and all L 1 customer ends are embedded with the instruction Executive Module.
For implementation method, the main distinction of two embodiment is, in the present embodiment; When service end is carried out the active defence and is attacked the attack source; The abnormality processing module is directly issued operational order and the direct-connected L 1 customer end in attack source, and other client transmissions data are no longer passed through in the centre, and this L 1 customer end is after filtering the data of attack source transmission; Other clients are no longer passed through in also directly passback when service end passback data.Other implementation procedures are all identical, repeat no more at this.
According to the foregoing description, just can realize the utility model well.The foregoing description is merely two kinds of situation of the utility model, is not the whole circumstances, and the protection range of the utility model includes but not limited to the foregoing description.
