Description

Method and device for determining content server

Technical Field

The invention relates to the technical field of website detection, in particular to a method and a device for determining a content server.

Background

A content server is a type of website that is used to provide services for other websites, such as storing pictures for other websites, analyzing viewer information, performing traffic rating and content filtering, etc., which are not typically displayed directly to a user.

After a user inputs a website in a browser of a terminal device and searches, the browser can visit a website corresponding to the website and also visit a plurality of websites (many websites belong to content server type websites) along with the website, the websites are used for providing advertisement content, statistical access information or pictures for the websites directly visited by the user, and the users of the websites visited along with the browser cannot sense the websites.

Because the content server is not a malicious website generally, when the website security detection is performed, if the content server can be filtered out, the efficiency of the website security detection can be improved.

At present, a method for determining whether a website is a content server specifically includes: when a user accesses a certain website through a browser of a terminal device, the browser initiates a request for accessing the website to a gateway device, the gateway device obtains the request, determines a Uniform Resource Locator (URL) of the website according to the request, records the URL, forwards the request to a target server (a server running the website), the target server responds to the request after receiving the request and returns a response message to the gateway device, and the gateway device judges whether the URL is a content server according to data contained in the response message. For example, when the data included in the response message is a session, blank content, or a 1 × 1 picture, the URL is determined to be the content server.

The above method of determining a content server is inefficient.

Disclosure of Invention

The embodiment of the invention provides a method and a device for determining a content server, which are used for improving the efficiency of determining the content server.

In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:

in a first aspect, a method for determining a content server is provided, including: the gateway equipment acquires a website access record in a preset time period, wherein the website access record comprises N Uniform Resource Locators (URLs) accessed in the preset time period and access times corresponding to the N URLs, and N is an integer greater than 0; the gateway equipment determines M target URLs in the N URLs according to the website access records, wherein the M target URLs are M URLs with the highest probability of being a content server in the N URLs, and M is an integer which is greater than 0 and less than or equal to N; the gateway equipment accesses a Host corresponding to each URL in M target URLs, and receives M parameters returned by a plurality of target servers running the M hosts of the M target URLs, wherein one parameter comprises a hypertext transfer protocol (HTTP) return value and the number of bytes of return data; the gateway device determines the content servers in the M target URLs according to the M parameters.

In the method provided by the first aspect, the URL with a low probability of being the content server in the URLs of the plurality of websites is excluded by adopting the access records of the websites, so that the number of URLs of which the gateway equipment needs to determine whether to be the content server is greatly reduced, and the efficiency of determining the content server by the gateway equipment is improved.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. "plurality" herein means two or more.

An embodiment of the present invention provides a network system for implementing the method provided in the embodiment of the present invention, as shown in fig. 1, including: the system comprises one or more terminal devices, a gateway device connected with the one or more terminal devices, and one or more target servers connected with the gateway device. The user may access the website through a terminal device, the terminal device may be a computer, a mobile phone, or a tablet computer, the gateway device is disposed at an exit of a terminal device network, and is configured to process (for example, message filtering or message detecting) and/or forward a message communicated between the terminal device and a target server, the gateway device may specifically be a router or a firewall, and one or more websites may be run on one target server. It should be noted that, in order to make the description clearer, in the description of the embodiment of the present invention, the content server refers to a type of website, which is used to provide services for other websites, and the target server refers to a hardware carrier running the website.

The device for executing the method provided by the embodiment of the present invention may be a gateway device, and the hardware architecture composition of the gateway device may refer to fig. 2, including: a network interface, a memory connected to the network interface, and a Central Processing Unit (CPU) connected to the memory.

The network interface can be divided into an input interface and an output interface, wherein the input interface is used for inputting network data to the gateway device, and the output interface is used for outputting the network data from the gateway device;

the CPU is composed of an arithmetic unit and a controller, the arithmetic unit is mainly used for processing network data, and the controller is used for analyzing instructions and sending control signals to all parts of the system orderly and purposefully according to the requirements of the instructions so that the whole system works coordinately and consistently. The memory can store network data and can read the stored network data according to the command. The CPU may be specifically arm (advanced RISC machines), mips (microprocessor with interleaved Pipeline stages), X86 processor, and the like.

An embodiment of the present invention provides a method for determining a content server, as shown in fig. 3, including:

301. the gateway equipment acquires a website access record in a preset time period, wherein the website access record comprises N accessed URLs in the preset time period and access times corresponding to the N accessed URLs, and N is an integer greater than 0.

The length of the preset time period may be set according to an actual application scenario or a requirement, for example, the preset time period may be 5 minutes or 10 minutes, and the length of the preset time period is not specifically limited in the embodiment of the present invention.

Specifically, in the website access record, one URL represents one website, and one URL corresponds to the number of times of access of the URL. The gateway device may record all URLs visited within a preset time period, and then count the number of visits of each URL to obtain a website visit record. For example, the website access record may be as shown in table 1, wherein the number of accesses of URL1 is 3, the number of accesses of URL2 is 9, and the number of accesses of URL3 is 7.

TABLE 1

URL	Number of accesses
		URL1	3
URL2	9
		URL3	7

In order to make the way of acquiring the URL by the gateway device clearer, a brief description is first made of a process of accessing the website by the user. When a user accesses a website through terminal equipment, the terminal equipment sends a request for accessing the website to gateway equipment, the gateway equipment processes the request according to the function provided by the gateway equipment and then sends the request to a target server running the website, the target server returns a response message to the gateway equipment after responding to the request, and the gateway equipment detects data contained in the response message according to the provided function and then returns the data to the terminal equipment.

The gateway device may obtain the URL of the website according to the received request for the terminal device to access the website. Specifically, the request for accessing the website received by the gateway device may be an HTTP message, a header of the request for accessing the website includes a Host field and a Path field, and the URL of the website may be obtained by sequentially connecting contents in the Host field and the Path field. For example, if the content in the Host field is s3.tbcdn.com and the content in the Path field is get/img/3.js, then the URL of the website is s3.tbcdn.com/get/img/3. js. The method provided by the embodiment of the invention can determine the content server based on the actual request for accessing the website, so that the method can adapt to the continuously changed or newly added content server.

302. The gateway device determines M target URLs in the N URLs according to the website access records, wherein the M target URLs are M URLs with the highest probability of being a content server in the N URLs, and M is an integer which is larger than 0 and smaller than or equal to N.

Optionally, the step 302 may include, in a specific implementation: and determining the URL meeting the condition 1 and/or the condition 2 in the N URLs as a target URL.

Optionally, the website access record further includes identifiers of terminal devices accessing N URLs within a preset time period, in this case, the step 302 may include, when implemented specifically: determining, as the target URL, a URL that satisfies one or more of condition 1, condition 2, and condition 3 among the N URLs. The identifier of the terminal device is used to uniquely identify the terminal device, and may specifically be an Internet Protocol (IP) address or a Media Access Control (MAC) address of the terminal device. The gateway device may obtain the identifier of the terminal device accessing the website according to a process in which the gateway device establishes a connection with the terminal device accessing the website. Specifically, in a preset time period, how many different terminal devices access a URL, and how many identifiers of the terminal devices accessing the URL are included in the website access record.

In the above two alternative methods, condition 1 is: the first-level domain name corresponding to the URL is located at the top X% in the first sequencing result, the first sequencing result is obtained after sequencing the first-level domain names corresponding to the N URLs according to the sequence of the access times from large to small, or the Host corresponding to the URL is located at the top Y% in the second sequencing result, and the second sequencing result is obtained after sequencing the Host corresponding to the N URLs according to the sequence of the access times from large to small; the condition 2 is: the Host corresponding to the URL is not accessed independently; the condition 3 is: the number of the identifications of the terminal devices accessing the URL is greater than or equal to a first preset threshold, and X, Y are integers which are greater than 0 and smaller than 100.

The value of X may be determined according to the actual application scenario, for example, when the value of N is large, the value of X may be set to be large, and when the value of N is small, the value of X may be set to be small, for example, X may be 80 or 50. The value of Y is determined in the same way. The first preset threshold may be determined according to an actual application scenario, which is not specifically limited in the embodiment of the present invention, for example, when determining a content server in a website accessed by a terminal device in an enterprise, the first preset threshold may be set to 10% or 20% of the total number of the terminal devices in the enterprise.

Wherein, the URL includes a Host and a Path, for example, when the URL is s3.tbcdn.com/get/img/3.js, the Host of the URL is: com, Path is: get/img/3.js, where the URL corresponds to a primary domain name: com. When a URL only includes a Host, the Host corresponding to the URL is the URL.

Specifically, since the number of access times of the content server is higher than that of an ordinary website (i.e., a non-content server), when the number of access times of the first-level domain name or Host of the URL is larger, the probability that the URL is the content server is larger; since most people visit the Host of the URL of a commonly used website (e.g., hundredth or Taobao), and the commonly used website is not a content server, if the Host of a URL is not visited alone, the probability that the URL is a content server is high; since the content server is a website accompanied by access other than a website directly accessed by the user, and different users may accompany access to the same content server when accessing different websites, the probability that the URL is the content server increases as the number of identifiers of terminal devices accessing the URL increases.

Step 302 is illustrated below by way of a specific example, where condition 1 is: the first-level domain name corresponding to the URL is at the top X% in the first sorted result. If N is 10, 10 URLs are: s3.tbcdn.com/get/img/3.js, da.so.com/q/136614, s3.tbcdn.com, china.baidu.com/query 64, wenwenwenwen.sogou.com/query, mingyi.sogou.com/mingyiquery, pic.tbcdn.com/p ═ 06050, china.baidu.com, s3. tbcdn.com/query 64, wenwen.sogou.com/. query, the first-level domain names of 10 URLs are respectively: com, so.com, tbcdn.com, baidu.com, sogou.com, tbcdn.com, baidu.com, tbcdn.com, sogou.com. The number of times the primary domain name corresponding to 10 URLs was accessed is shown in table 2.

TABLE 2

First level Domain name	Number of accesses
		tbcdn.com	4
so.com	1
		baidu.com	2
sogou.com	3

Then, the first-level domain names corresponding to the N URLs are ordered according to the sequence of the access times from large to small, and the result obtained after the ordering is: and tbcdn.com, sogout.com, baidu.com, so.com, when X is 50, the top 50% of the first-level domains in the ordering result are named tbcdn.com and sogout.com.

In the example described based on table 2, the URL corresponding to the URL where the Host is not separately visited includes: da.so.com/q/136614, wenwenwen.sogou.com/ques, mingyi.sogou.com/mingyiquery, pic.tbcdn.com/p [ (& w ═ 06050, and wen.sogou.com/? And (5) query.

In this example, in a specific implementation, if the URL satisfying the condition 1 and the condition 2 is determined as the target URL in the 10 URLs, the target URL is:

wenwenwen. query, mingyi.sogou.com/mingyiquary, wenwenwenwen.sogou.com/ques and pic.tbcdn.com/p ═ 06050.

303. The gateway device accesses a Host corresponding to each of the M target URLs, and receives M parameters returned by a plurality of target servers running the M hosts of the M target URLs, wherein one parameter comprises a Hyper Text Transfer Protocol (HTTP) return value and the number of bytes of return data.

Specifically, the gateway device may obtain the parameter corresponding to the target URL according to a response message returned by the target server running the target URL. The response message returned by the target server and received by the gateway device may be an HTTP message, the response message includes an HTTP return value and returned data, the response message may include a field indicating the number of bytes of the returned data, and the gateway device may obtain the number of bytes of the returned data according to the field.

Specifically, when the HTTP return value is 200, it indicates that the target server has successfully returned the data requested by the gateway device, and the data included in the response message is the data requested by the gateway device. When the HTTP return value is not 200, it indicates that the target server has not successfully returned the data requested by the gateway device.

304. The gateway device determines the content servers in the M target URLs according to the M parameters.

The step 304 may be implemented as follows: and when the HTTP return value in the parameter corresponding to the target URL is not 200, or the HTTP return value in the parameter corresponding to the target URL is 200 and the number of bytes of returned data is less than or equal to a second preset threshold value, determining that the target URL is the content server.

The second preset threshold may be an empirical value, generally not greater than 100, and may be specifically set to several or several tens according to actual experience.

An embodiment of the present invention further provides a method for determining a content server, which is used to exemplarily describe the method described in fig. 3, in this example, a target URL satisfies condition 1, condition 2, and condition 3, where condition 1 is: the first-level domain name corresponding to the URL is at the top X% in the first sorting result, and the explanation of the content related to the above embodiment in this example can be found in the above, as shown in fig. 4, where the method includes:

401. the gateway equipment acquires the website access record in a preset time period.

The website access record comprises N accessed URLs within a preset time period, access times corresponding to the N URLs and identifications of terminal devices accessing the N URLs within the preset time period.

402. And the gateway equipment sorts the primary domain names corresponding to the N URLs according to the sequence of the access times from large to small to obtain a first sorting result.

403. The gateway device determines whether the primary domain name corresponding to each of the N URLs is at the top X% in the first ranking result.

If yes, go to step 404, otherwise go to step 409.

404. The gateway device determines whether the Host corresponding to the URL has not been accessed separately.

If yes, go to step 405, otherwise go to step 409.

405. The gateway device determines whether the number of different identifiers of the terminal device accessing the URL is greater than or equal to a first preset threshold value.

If yes, go to step 406, otherwise go to step 409.

406. And the gateway equipment accesses the Host corresponding to the URL and receives the parameter returned by the target server operating the Host.

Wherein the parameters comprise an HTTP return value and the number of bytes of return data.

407. The gateway device determines whether the HTTP return value is not 200 or whether the HTTP return value is 200 and the number of bytes of returned data is less than or equal to a second preset threshold.

If yes, go to step 408, otherwise go to step 409.

408. The URL is determined to be a content server.

409. It is determined that the URL is not a content server.

As can be seen from the description based on the embodiment described in fig. 4, whether the URL is a content server can be detected online on the gateway device by deploying a program for implementing the method shown in fig. 4 in the gateway device.

According to the method provided by the embodiment of the invention, the URL with low probability of being the content server in the URLs of a plurality of websites is excluded by adopting the access records of the websites, so that the number of the URLs of which the gateway equipment needs to determine whether to be the content server is greatly reduced, and the efficiency of determining the content server by the gateway equipment is improved. When the website security detection is performed, the probability that the excluded URL is the content server is low, and even if the content server is included, the number of the excluded URLs is small, so that the efficiency of the website security detection cannot be greatly influenced.
