Example 1
The embodiment of the invention provides an abnormal classification detection method of network flow.
Fig. 1 is a flowchart of an abnormal classification detection method of network traffic according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S102, a target log generated by the target website under the target network flow is obtained.
In the technical solution provided in step S102, the target network traffic is traffic to be detected whether abnormal or not. The target log, that is, the website log, is generated for the target website under the target network traffic. The target log is a file ending in a log which records various kinds of original information such as processing requests received by the server and server operation errors, can record information such as operation conditions and access requests of a target website in the operation process, and can clearly determine information such as what IP, what time, what operating system, what browser, what resolution display and the like a user accesses to which page of the target website and whether the access is successful or not.
Alternatively, the target log of this embodiment may be represented by a log ID, for example, the target log is represented by xxx _001, xxx _002, xxx _003, or the like.
Step S104, obtaining the attribute value set of the target log.
In the technical solution provided in step S104, after a target log generated by the target website under the target network traffic is obtained, an attribute value set of the target log is obtained, where an attribute value in the attribute value set is used to indicate a state of a field associated with the attribute value under the target attribute.
In this embodiment, the target log includes fields, such as a field a corresponding to a cookie, a field B corresponding to an Internet Protocol (IP), a field C corresponding to a User Agent (User Agent), etc., wherein the User Agent may be a browser, and may further include fields such as a timestamp, a web arrival (referrer), etc., each of which may have a plurality of attribute values corresponding to different data presentations. The attribute value set of the target log comprises an attribute value obtained by calculating a field of the target log, wherein the attribute value is used for indicating the state of the target log under the field associated with the attribute value, and the state can be a normal state or an abnormal state. Optionally, the attribute value of the a field is 1, which is used to indicate that the state of the a field under the cookie attribute is a cookie format abnormal state, the attribute value of the a field is 2, which is used to indicate that the state of the a field under the cookie attribute is an exposure abnormal state, the attribute value of the B field is 16, which is used to indicate that the state of the B field under the IP attribute is an IP change too fast state, and the like, which is not limited herein.
Step S106, synthesizing at least one target attribute value associated with the same field into a first target attribute value, in case the set of attribute values comprises a predefined target attribute value.
In the technical solution provided in step S106, after obtaining a target log generated by a target website under a target network traffic, if the attribute value set includes a predefined target attribute value, synthesizing at least one target attribute value associated with the same field into a first target attribute value.
In this embodiment, the attribute value of the exception field is predefined to obtain a target attribute value. For example, for field a corresponding to a cookie, the rule defines the value a: 1 is used for indicating that the state of the field A under the cookie attribute is cookie format exception under the condition that the target attribute value is 1; the rule defines the value a: 2, used for indicating that the state of the field A under the cookie attribute is cookie exposure abnormity under the condition that the target attribute value is 2; the rule defines the value a: 4, used for showing that the state of the field A under the cookie attribute is cookie click abnormity under the condition that the target attribute value is 4; the rule defines the value a:8, used for indicating that the state of the field A under the cookie attribute is that the cookie changes too fast under the condition that the target attribute value is 8; the rule defines the value a: and 16, for indicating that the state of the field a under the cookie attribute is cookie time-out in case that the target attribute value is 16. Wherein the rule definition value is a condition defined by the anomaly classification.
Optionally, for field B corresponding to IP, the rule defines the value B:1, which is used for indicating that the state of the field B under the IP attribute is crawler IP abnormity under the condition that the target attribute value is 1; the rule defines the value B: 2, the field B is used for indicating that the state of the field B under the IP attribute is the data center IP anomaly if the target attribute value is 2; the rule defines the value B: 4, used for showing that the state of the field B under the IP attribute is proxy IP abnormal under the condition that the target attribute value is 4; the rule defines the value B: 8, used for showing that the state of the field B under the IP attribute is a standby IP exception under the condition that the target attribute value is 8; the rule defines the value B: and 16, for indicating that the state of the field B under the IP attribute is that the IP changes too fast when the target attribute value is 16.
Optionally, for field C corresponding to the usergent, the rule defines the value C:1 is used for indicating that the state of the field C under the Useragent attribute is simple crawler Useragent under the condition that the target attribute value is 1; the rule defines the value C: 2 is used for indicating that the state of the field C under the Useragent attribute is Useragent too short under the condition that the target attribute value is 2; the rule defines the value C: 4 is used to indicate that the state of field C under the Useragent attribute is a high-level crawler Useragent, if the target attribute value is 4.
It should be noted that the predefined target attribute value is only an example of the embodiment of the present invention, and the predefined target attribute value that does not represent the embodiment of the present invention is only the above, and any predefined target attribute value for determining whether the website traffic is abnormal is within the scope of the embodiment, and is not illustrated here.
The embodiment determines the attribute values in the attribute value set, may perform matching calculation with the predefined target attribute value, and synthesizes at least one target attribute value associated with the same field into a first target attribute value in the case that the attribute value set includes the predefined target attribute value, where the first target attribute value is also the synthesized attribute value of the target log. For example, the attribute value set includes attribute values 1, 8, 16 of the a field, that is, the rule definition value a: 1, rule definition value a:8, rule definition value A: 16, synthesizing the target attribute values 1, 8 and 16 of the A field into a first target attribute value 25 of the A field; the attribute value set also includes an attribute value 1 of the C field, i.e., the corresponding rule definition value C:1, the first target attribute value may be the target attribute value 1 of the C field.
And step S108, determining that the target network flow has an abnormal state of the target type under the condition that the first target attribute value is successfully matched with the predefined second target attribute value.
In the technical solution provided in step S108, when the first target attribute value is successfully matched with the predefined second target attribute value, it is determined that the target network traffic has an abnormal state of the target type, where the second target attribute value is used to indicate that a field associated with the second target attribute value belongs to the abnormal state of the target type.
In this embodiment, a second target attribute value is predefined, which corresponds to the abnormal state of the target type to which the field belongs, i.e. the abnormal classification result. For example, if the abnormal state of the target type is a frequency abnormality, the second target attribute value may be an attribute value 8 in the field a, that is, the rule definition value a is: 8, the second target attribute value may also be an attribute value 16 in the B field, and the rule definition value B is: 16; for another example, if the abnormal state of the target type is a crawler problem, the rule definition value may be an attribute value 1 in a field B, corresponding to the rule definition value B:1, it may also be an attribute value 1 in the C field, and the corresponding rule defines a value C:1, it may also be an attribute value 4 under the C field, and the corresponding rule defines a value C: 4, for representing a set of various crawler questions.
It should be noted that the predefined second target attribute value and the abnormal state of the field associated with the second target attribute value belonging to the target type are merely an example of the embodiment of the present invention, and do not represent that the second target attribute value and the abnormal state of the field associated with the second target attribute value belonging to the target type of the embodiment of the present invention are merely the above examples, and any second target attribute value that can be predefined for determining whether the website traffic is abnormal and the abnormal state of the field associated with the second target attribute value belonging to the target type are within the scope of the embodiment, and are not illustrated here.
Under the condition that the first target attribute value is successfully matched with the predefined second target attribute value, for example, the binary value of the first target attribute value and the binary value of the predefined second target attribute value are logically and-processed, if the output result is greater than 0, it is determined that the target log has an abnormal state of the target type, and further it is determined that the target network traffic corresponding to the target log has an abnormal state of the target type, that is, an abnormal classification result is obtained, the purpose of classifying the abnormality of the target network traffic is achieved, and the abnormal classification result can be used in a report for finally counting the target network traffic.
For example, the first target attribute value of target log xxx _001 is 25 under the A field, i.e., A: 25, C:1, the matching with the predefined second target attribute value 1 in the a field, the predefined second target attribute value 8 in the a field, and the predefined second target attribute value 16 in the a field is successful, that is, the matching with the predefined second target attribute value 1 in the a field, that is, the predefined matching with the predefined second target attribute value 16 in the a field is successful, that is, the predefined matching with the predefined second target attribute value 1 in the a field is successful: 1. a: 8. a: 16, the exception status of the target type may be a: 1, and A:8, and a cookie time timeout exception classification result corresponding to a 16.
In this embodiment, the abnormal state of the target type may match a plurality of condition defined by the classification (rule definition value), for example, the frequent abnormal classification result may match a:8(cookie is changed too fast) and B:16(IP is changed too fast), and as long as the first target attribute value satisfies one of the condition defined by the classification, the abnormal state of the target type may be determined to be the abnormal classification corresponding to the condition defined by the classification.
In this embodiment, the target log simultaneously satisfies the conditions defined by different abnormal classifications, and then participates in different abnormal classification calculations in the final abnormal classification result.
In the embodiment, a target log generated by a target website under target network traffic is acquired; acquiring an attribute value set of a target log, wherein an attribute value in the attribute value set is used for indicating the state of a field associated with the attribute value under a target attribute; synthesizing at least one target attribute value associated with the same field into a first target attribute value if the set of attribute values includes a predefined target attribute value; and under the condition that the first target attribute value is successfully matched with a predefined second target attribute value, determining that the target network traffic has an abnormal state of a target type, wherein the second target attribute value is used for indicating that a field associated with the second target attribute value belongs to the abnormal state of the target type. That is to say, the target attribute values are predefined, under the condition that the attribute value set of the target log includes the predefined target attribute value, at least one target attribute value is synthesized into a first target attribute value (synthesized attribute value), the first target attribute value is matched with a predefined second target attribute value which is classified well, and under the condition that the matching is successful, the target network traffic is determined to have an abnormal state of the target type, so that the technical problem that the efficiency of classifying and detecting the abnormal traffic of the website is low is solved, and the technical effect of improving the efficiency of classifying and detecting the abnormal traffic of the website is achieved.
As an alternative implementation, the step S106, synthesizing at least one target attribute value associated with the same field into a first target attribute value includes: under the condition that a plurality of target attribute values are associated with the same field, carrying out logic OR processing on binary values of the plurality of target attribute values associated with the same field to obtain a first target attribute value; in the case where there is one target attribute value associated with the same field, the target attribute value is determined as the first target attribute value.
In this embodiment, when a plurality of target attribute values associated with the same field are provided, a binary value of the plurality of target attribute values associated with the same field is logically or-processed to obtain a first target attribute value, that is, a binary value of a different target attribute value associated with the same field is logically or-processed to generate a new attribute value, where the first target attribute value is a composite attribute value in a target log, for example, if the target log includes an a field and a C field, the target attribute value associated with the a field is 1, 8, and 16, and corresponds to a rule definition value a: 1. a: 8. a: 16, the binary values of 1, 8, 16 associated with the a field are logically or-ed to obtain 25, which may be represented by a 1: and 25, respectively.
In a case where there is one target attribute value associated with the same field, the target attribute value is determined as the first target attribute value, and the target attribute value may be directly determined as the first target attribute value, for example, if the target attribute value associated with the C field is 1, then 1 is directly determined as the first target attribute value, and the ratio of C:1 is shown.
As an optional implementation manner, before determining that the target abnormal state exists in the target network traffic at step S108, the method further includes: traversing a plurality of second target attribute values associated with the exception state of the target type; performing logic and processing on the binary value of the first target attribute value and the binary value of a second target attribute value traversed currently to obtain a target processing result; when the target processing result is larger than the target value, determining that the first target attribute value is successfully matched with the traversed second target attribute value; and determining the next second target attribute value in the plurality of second target attribute values as the currently traversed second target attribute value under the condition that the target processing result is equal to 0 and the plurality of second target attribute values are not traversed.
In this embodiment, the predefined second target attribute values are multiple, and before it is determined that the target network traffic has the target abnormal state, the multiple second target attribute values associated with the abnormal state of the target type are traversed, that is, the attribute values of the abnormal classification are traversed. When a second target attribute value is traversed currently, the binary value of the first target attribute value and the binary value of the second target attribute value are subjected to logic AND processing to obtain a target processing result, and the first target attribute value is matched in a binary mode, so that the speed of matching the first target attribute value can be increased.
After the target processing result is obtained, it is determined whether the target processing result is greater than a target value, for example, the target value is 0, and it is determined whether the target processing result is greater than 0. And if the target processing result is judged to be larger than the target value, determining that the first target attribute value is successfully matched with the traversed second target attribute value, determining that the target network flow has an abnormal state of the target type, namely, obtaining an abnormal classification result meeting the condition, and outputting the abnormal classification result.
Optionally, when the target processing result is not greater than the target value and the plurality of second target attribute values are not traversed, determining a next second target attribute value of the plurality of second target attribute values as a currently traversed second target attribute value, and continuing to match the first target attribute value with the next second target attribute value until the plurality of second target attribute values associated with the abnormal state of the target type are traversed.
As an optional example, before determining that the target abnormal state exists in the target network traffic at step S108, the method further includes: traversing a plurality of second target attribute values associated with the first type of abnormal state, and performing logical and processing on binary values of the first target attribute values and binary values of the traversed second target attribute values to obtain a target processing result, wherein the target type includes a first type, for example, a frequency abnormal type; when the target processing result is larger than the target value, determining that the first target attribute value is successfully matched with the traversed second target attribute value; determining that the target network traffic has the abnormal state of the target type comprises: it is determined that a first type of abnormal condition exists for the target network traffic.
As an optional example, after logically and-processing the first target attribute value and the traversed target attribute value to obtain a target processing result, the method further includes: when the target processing result is not larger than the target value and a plurality of second target attribute values associated with the first type of abnormal state are not traversed, performing logic and processing on the binary number value of the first target attribute value and the binary number value of the traversed next second target attribute value to obtain a second processing result; when the second processing result is larger than the target value, determining that the first target attribute value is successfully matched with the traversed next second target attribute value; optionally, after it is determined that the first target attribute value is successfully matched with the traversed next second target attribute value, if the plurality of second target attribute values associated with the abnormal state of the first type are not traversed, continuing to match the first target attribute value according to the above method until the plurality of second target attribute values associated with the abnormal state of the target type are traversed; optionally, when the second processing result is not greater than the target value and the second target attribute values associated with the abnormal state of the first type are not traversed, continuing to match the first target attribute value according to the above method until the second target attribute values associated with the abnormal state of the target type are traversed.
As an alternative example, before logically and-processing the binary value of the first target attribute value and the binary value of the traversed next second target attribute value to obtain the second processing result, the method further includes: traversing a plurality of second target attribute values associated with the abnormal state of the second type under the condition that the plurality of second target attribute values associated with the abnormal state of the first type are traversed, and performing logic and processing on binary values of the first target attribute values and binary values of the traversed second target attribute values to obtain a third processing result, wherein the target type comprises the second type, for example, the second type is a crawler problem; when the third processing result is larger than the target value, determining that the first target attribute value is successfully matched with the traversed second target attribute value; determining that the target network traffic has the abnormal state of the target type comprises: determining that the target network traffic has a second type of abnormal condition.
As an optional implementation manner, after synthesizing at least one target attribute value associated with the same field into the first target attribute value in step S106, the method further includes: storing the first target attribute value in a target log.
In this embodiment, after at least one target attribute value associated with the same field is synthesized into a first target attribute value, that is, after the synthesized attribute value of the target log is obtained, the first target attribute value is stored in the target log, that is, the first target attribute value may be used as an attribute value finally stored in the target log, thereby saving the storage space.
As an optional implementation manner, in step S104, acquiring the set of attribute values of the target log includes: acquiring a plurality of target fields in a target log; a set including attribute values respectively associated with the plurality of target fields is determined as a set of attribute values.
In this embodiment, when acquiring the set of attribute values of the target log, part of the target fields may be randomly acquired in the target log without acquiring all the fields. Each target field may include a plurality of attribute values, and a combination of the plurality of attribute values is determined as a set of attribute values.
