Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or the azimuth or the positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present invention and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus it should not be construed as limiting the present invention.
Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
The cloud WAF is a cloud Web application defense system based on a content delivery network (Content Delivery Network, CDN), and a user can easily realize the protection of a website by only changing the configuration of a domain name system (Domain Name System, DNS) of the website domain name without deploying additional software programs or hardware equipment.
As shown in fig. 1, a large cloud WAF architecture is made up of multiple WAF nodes. For normal access requests of users, the WAF node forwards the access requests to a website requested by the users, response data of a server of the website is returned to the users in a primary way, and for various identified attack requests, the WAF node directly intercepts and returns an interception page to the users.
Currently, the use of cloud Web application defense system (Web Application Firewall, WAF) architecture to defend various network attacks has been developed as a very mature technology, but the existing cloud WAF architecture generally only carries out a simple prompt after intercepting the attack behavior, as shown in fig. 2. On the other hand, for the prompting page such as 404 pages or 503 pages returned by the client website, the WAF node will also generally return directly to the requester, as shown in fig. 3.
A large cloud WAF architecture often has access to tens of thousands of customer sites, with hundreds of millions of pages 404, 503 intercepted and returned each day. If only a simple prompt utterance is returned and such pages are not utilized, the method is a waste of massive traffic resources.
Based on the above researches, the present embodiment provides an information pushing method, device, system and readable storage medium, which push information on a page returned to a user in a cloud WAF workflow, thereby realizing effective utilization of traffic resources.
Referring to fig. 4, fig. 4 is a schematic structural diagram of an information pushing system 1 according to the present embodiment. The information push system 1 provided in the present embodiment includes an information distribution platform 200 and a cloud WAF platform 100. The cloud WAF platform 100 is in communication connection with the information distribution platform 200 through a network, so as to realize data exchange.
In this embodiment, the cloud WAF platform 100 includes at least one WAF node 10, where each WAF node 10 is connected to at least one website, and is configured to receive an access request from a user terminal to the connected website, and identify the access request, so as to implement protection on the connected website.
Alternatively, in this embodiment, the WAF node 10 may be an electronic device having data processing capability, and the internal structure thereof may include an information pushing device 11, a memory 12, a processor 13, and a communication unit 14, as shown in fig. 5.
The memory 12, the processor 13 and the communication unit 14 are electrically connected directly or indirectly to each other to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The memory 12 stores an information pushing device 11, the information pushing device 11 includes at least one software functional module that may be stored in the memory 12 in the form of software or firmware (firmware), and the processor 13 executes various functional applications and data processing by running software programs and modules stored in the memory 12, such as the information pushing device 11 in the embodiment of the present invention, that is, implements the information pushing method in the embodiment of the present invention.
The Memory 12 may be, but is not limited to, a random access Memory (Random Access Memory, RAM), a Read Only Memory (ROM), a programmable Read Only Memory (Programmable Read-Only Memory, PROM), an erasable Read Only Memory (Erasable Programmable Read-Only Memory, EPROM), an electrically erasable Read Only Memory (Electric Erasable Programmable Read-Only Memory, EEPROM), etc. The memory 12 is used for storing a program, and the processor 13 executes the program after receiving an execution instruction.
The processor 13 may be an integrated circuit chip with data processing capabilities. The processor 13 may be a general-purpose processor including a central processing unit (Central Processing Unit, CPU), a network processor (Network Processor, NP), and the like. The methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
The communication unit 14 is configured to establish a communication connection between the WAF node 10 and other devices (such as a website server, a user side, and the information distribution platform 200) through a network, so as to implement data transceiving operation. The network may include a wireless network or a wired network.
It is to be understood that the configuration shown in fig. 5 is merely illustrative and WAF node 10 may also include more or fewer components than shown in fig. 5 or have a different configuration than shown in fig. 5. The components shown in fig. 5 may be implemented in hardware, software, or a combination thereof.
In this embodiment, the information distribution platform 200 may be a single physical server or a server group formed by a plurality of physical servers for performing different data processing functions. The server group may be centralized or distributed. In some possible implementations, if information distribution platform 200 employs a single physical server, different logical server components may be assigned to the physical server based on different service functions.
Alternatively, in this embodiment, the information distribution platform 200 stores information that can be pushed, and the WAF node 10 may obtain information to be pushed from the information distribution platform 200.
Based on the implementation architectures of fig. 4 and fig. 5, please refer to fig. 6 in combination, fig. 6 is a flow chart of the information pushing method provided in the present embodiment. The method is performed by WAF node 10 shown in fig. 4 and is described in detail below with respect to the flowchart shown in fig. 6.
Step S10: and receiving an access request of the user terminal.
Step S20: and judging whether the user terminal is in a dynamic interception state according to the access request.
If the state is in the dynamic interception state, step S30 is performed.
Step S30: intercepting an access request of a user side, and acquiring information to be pushed according to parameter information of the user side and parameter information of a website to be accessed.
Step S40: according to the information to be pushed, generating an interception page comprising the information to be pushed, and pushing the interception page to the user side.
If a certain user terminal is in a dynamic interception state, the risk of the access request of the user terminal is indicated to be intercepted, so that after the user terminal is determined to be in the dynamic interception state, the embodiment intercepts the access request of the user terminal and returns an interception page to the user terminal.
In order to improve the utilization rate of the interception page, namely, the utilization rate of the traffic resource, in the embodiment, after intercepting the access request of the user side, the information to be pushed is obtained from the information distribution platform according to the parameter information of the user side and the parameter information of the website to be accessed. After the information to be pushed is obtained, generating an interception page comprising the information to be pushed according to the information to be pushed, namely configuring the information to be pushed on the interception page, and pushing the interception page to a user side.
By pushing the information on the interception page, the information pushing method provided by the embodiment can effectively utilize the traffic resources and avoid the waste of the traffic resources.
Optionally, in this embodiment, the access request of the user side includes an IP address of the user side and an IP address of a website to be accessed, and after receiving the access request of the user side, the WAF node may determine, according to the access request, whether the IP address of the user side is provided with a dynamic interception flag, and if the IP address of the user side is provided with the dynamic interception flag, determine that the user side is in a dynamic interception state. If the dynamic interception mark is not set, the access request of the user side can be forwarded to the website to be accessed.
Optionally, in order to improve the protection of the WAF node against website access, referring to fig. 7, in this embodiment, before forwarding the access request of the user side to the website to be accessed, the step of identifying the access of the user side may further include step S21.
Step S21: and judging whether the access of the user terminal is attack access or not.
If the access is a non-attack access, step S50 is performed. If the attack access is made, steps S30 to S40 are performed.
Step S50: and forwarding the access request of the user terminal to the website to be accessed.
And if so, judging that the access of the user is attack access, intercepting the access request of the user, and acquiring information to be pushed from an information distribution platform according to the parameter information of the user and the parameter information of a website to be accessed. After the information to be pushed is obtained, an interception page comprising the information to be pushed is generated according to the information to be pushed, and then the interception page is pushed to the user side, so that the effective utilization of the traffic resources is realized, and the waste of the traffic resources is avoided.
Optionally, in order to improve the processing efficiency of the WAF node, in this embodiment, after determining that the access of the user side is attack access, the method further includes:
judging whether the attack times of the user side in a preset time period reach a set interception threshold value.
If the interception threshold is reached, a dynamic interception mark is set for the user side. If the interception threshold is not reached, updating the attack times of the user.
After the access of the user terminal is judged to be attack access, judging whether the attack times of the user terminal in a preset time period reach a set interception threshold value, if so, setting a dynamic interception mark for the user terminal, namely setting the dynamic interception mark for the IP address of the user terminal, and if not, updating the attack times of the user terminal, namely adding 1 to the original attack access times of the user terminal.
It should be noted that after setting a dynamic interception flag for an IP address of a user terminal, that is, after opening dynamic interception for the IP address of the user terminal, an access request of the user terminal is intercepted in a set period of time, and each access of the user terminal is pushed with information in the set period of time, for example, the attack frequency of the user terminal in a preset period of time (for example, 5 minutes) reaches a set interception threshold, and all access requests of the user terminal are intercepted in a next set period of time (for example, 10 minutes). And after the set time period is exceeded, the access times (attack times) of the user terminal are cleared, and then the access request of the user terminal is identified again, so that the processing efficiency of the WAF node can be effectively improved.
It can be understood that if the access request does not have the characteristic information of attack access, the access of the user terminal is judged to be non-attack access, and then the access request of the user terminal is forwarded to the website to be accessed.
Because in practical applications, after forwarding the access request to the website to be accessed, the website server may not return the corresponding access content for some reasons, and only returns the page that cannot be accessed. Therefore, in order to further increase the utilization rate of the traffic resources, referring to fig. 8, in this embodiment, after forwarding the access request of the user terminal to the website to be accessed if the user terminal is not in the state of dynamic interception, the information pushing method provided in this embodiment further includes steps S60 to S90.
Step S60: and receiving response information of the website to be accessed.
Step S70: and identifying the response information, and judging whether the response information is a state code which cannot be accessed.
If the response information is not the inaccessible status code, step S90 is executed.
Step S80: according to the parameter information of the user side and the parameter information of the website to be accessed, obtaining information to be pushed, generating a prompt page comprising prompt contents corresponding to the information to be pushed and the status code according to the information to be pushed and the status code, and pushing the prompt page to the user side.
Step S90: and pushing the response information to the user side.
If the response information is a status code which cannot be accessed, the response information indicates that the access content corresponding to the access request cannot be obtained from the website server. If the response information is not the inaccessible status code, the content requested by the user side returned by the website server is indicated, so that the response information can be directly pushed to the user side.
Optionally, in this embodiment, the inaccessible status code includes a 404 status code and a 503 status code, and when the inaccessible status code is the 404 status code, it indicates that the resource requested by the ue does not exist, and the corresponding resource cannot be found. When the inaccessible status code is the 503 status code, it means that the request of the user side causes a service error to the website server, and the service cannot be provided normally.
In this embodiment, if it is determined that the response information is a status code that cannot be accessed, the information to be pushed is obtained from the information distribution platform according to the parameter information of the user side and the parameter information of the website to be accessed. After obtaining the information to be pushed, generating a prompt page comprising the information to be pushed and prompt contents corresponding to the status code according to the information to be pushed and the status code, namely configuring the information to be pushed and the prompt contents corresponding to the status code on the prompt page, and pushing the prompt page to a user side.
For example, when the response information is 404 status codes, the returned prompting page includes the information to be pushed and the prompting content corresponding to the 404 status codes, that is, the corresponding resource cannot be found. For another example, when the response information is 503 status code, the returned prompting page includes the information to be pushed and the prompting content corresponding to the 503 status code, that is, the service cannot be provided normally.
Since in actual use, some websites may not open the page information pushing configuration, in this embodiment, the step of identifying the response information and determining whether the response information is a status code that cannot be accessed may further include:
and judging whether the website to be accessed starts prompt page information pushing configuration.
And if the prompt page information pushing configuration is not started, pushing response information of the website to be accessed to the user side.
If the prompt page information pushing configuration is started, the response information is identified, and whether the response information is a state code which cannot be accessed is judged.
If the prompt page information pushing configuration is not started, the response information of the website to be accessed is directly pushed to the user side, and even if the response information is a state code which cannot be accessed, the information does not need to be pushed on a page which cannot be accessed and is returned to the user side. If the to-be-accessed website is opened with the prompt page information pushing configuration, the response information is identified, whether the response information is a state code which cannot be accessed is judged, when the response information is the state code which cannot be accessed, the to-be-pushed information is obtained according to the parameter information of the user side and the parameter information of the to-be-accessed website, a prompt page comprising the to-be-pushed information and prompt contents corresponding to the state code is generated according to the to-be-pushed information and the state code, and the prompt page is pushed to the user side.
Optionally, in this embodiment, the step of determining whether the website to be accessed opens the prompt page information push configuration may include:
and judging whether the website to be accessed opens 404 a page information pushing configuration and/or 503 a page information pushing configuration.
If the website to be accessed only opens 404 page information pushing configuration, the information to be pushed is obtained according to the parameter information of the user side and the parameter information of the website to be accessed only when the response information is 404 state codes, a prompt page comprising the information to be pushed and prompt content corresponding to the 404 state codes is generated according to the information to be pushed and the 404 state codes, and then the prompt page is pushed to the user side.
If the website to be accessed only opens 503 page information pushing configuration, the information to be pushed is obtained according to the parameter information of the user side and the parameter information of the website to be accessed only when the response information is 503 state code, a prompt page comprising prompt contents corresponding to the information to be pushed and the 503 state code is generated according to the information to be pushed and the 503 state code, and then the prompt page is pushed to the user side.
If the website to be accessed opens 404 the page information pushing configuration and the page information pushing configuration at the same time, when the response information is 404 the state code or 503 the state code, acquiring the information to be pushed according to the parameter information of the user side and the parameter information of the website to be accessed, generating a prompt page comprising the information to be pushed and prompt content corresponding to the state code according to the information to be pushed and the state code, and pushing the prompt page to the user side.
Optionally, in this embodiment, after determining that the user side is in a dynamic interception state and intercepting an access request of the user side, the WAF node may also determine whether a website to be accessed opens an interception page information pushing configuration, if the website to be accessed does not open the interception page information pushing configuration, directly return an interception page only including interception information to the user side, if the interception page information pushing configuration is opened, acquire information to be pushed according to parameter information of the user side and parameter information of the website to be accessed, then generate an interception page including information to be pushed according to the information to be pushed, and push the interception page to the user side.
In this embodiment, when each website accesses the cloud WAF platform, whether to start the interception page information pushing configuration and the prompting page information pushing configuration may be selected independently. The access flow can be as follows:
after the website is accessed to the cloud WAF platform, whether the information pushing function is started or not can be selected, if the information pushing function is not started, the cloud WAF platform only opens the WAF defense function for the website, and if the information pushing function is started, the website can autonomously select whether to start the interception page information pushing configuration and the prompt page information pushing configuration. The prompting page information pushing configuration comprises 404 page information pushing configuration and 503 page information pushing configuration, and the website can autonomously select to start 404 page information pushing configuration and/or 503 page information pushing configuration.
After the website starts the interception page information pushing configuration, an access request of a user side can be intercepted, information to be pushed is obtained according to parameter information of the user side and parameter information of a website to be accessed, an interception page comprising the information to be pushed is generated according to the information to be pushed, and the interception page is pushed to the user side.
