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.
At present, for frequently updated software, especially for feature library version update of security software, network overhead required for checking version update is far greater than that of substantial content itself, taking a version update checking mechanism implemented by Web Service (Web Service for short) as an example, most of overhead of initiating one-time version update checking is used for data encapsulation and network transmission, and redundancy is very high. Based on the above, an object of the embodiments of the present invention is to provide a method and an apparatus for upgrading a software version based on DNS query, which reduce network overhead required for software update checking, reduce redundancy, and improve efficiency of version upgrade query.
For the sake of understanding the present embodiment, a software version upgrading method based on DNS query disclosed in the present embodiment is first described in detail.
Embodiment one:
referring to fig. 1, a software version upgrading method based on DNS query, provided by an embodiment of the present invention, applied to a client, may include the following steps:
step S101, obtaining characteristic information of software to be detected.
In an embodiment of the present invention, the characteristic information includes one or more of the following information: software version number, software serial number, host network card MAC address, host CPU serial number and host hard disk serial number. The characteristic information is classified into two types, namely the characteristic of the software to be detected and the characteristic of the running environment of the software to be detected. The embodiment of the invention obtains the characteristics of the software to be detected by a software self method, for example: and reading the file with the software version number, and acquiring the software version number of the software to be detected. The embodiment of the invention can acquire the characteristics of the running environment of the software to be detected by a method provided by an operating system, for example: executing the window command to obtain the version number of the windows operating system in the running environment. If the software to be detected is controlled by the authorized license, further acquiring the characteristic data of the running environment, such as: the host network card MAC address, the host CPU serial number, the host board, the host hard disk serial number and other hardware unique identifiers. Where the authorized license includes, but is not limited to, a duration of use, a number of uses, an open function, etc.
In order to ensure that the received DNS query result is not cached or falsified, a random number, a time stamp and other change factors are added into the feature information, and the feature information added with the change factors is used as a DNS query request to be sent to a software update server after being processed in the following steps.
Step S102, the characteristic information is subjected to coding processing to obtain a first sub domain name.
In the embodiment of the present invention, one or more pieces of feature information in step S101 are combined, and after the combination, encoding processing is performed, and after the encoding processing, a first sub domain name is obtained, where the first sub domain name is a prefix of a domain name query request. The domain name query request may refer to a DNS query request, where DNS may refer to a service of the internet, and is used as a distributed database that maps domain names and IP addresses to each other, so that a user can access the internet more conveniently. DNS uses TCP and UDP ports 53. Network packet capturing is performed in the running environment of the software to be detected, and the prefix of the domain name inquiry request is observed to change from time to time by monitoring the UDP connection with the destination port number of 53, and the prefix is usually a combination of random letters and numbers.
Currently, the limit for the length of each level of domain name is 63 characters, and the total length of the domain name cannot exceed 253 characters. Since the maximum length of each level of domain name of DNS cannot exceed 63 characters, the feature data acquired in step S101 is subjected to encoding processing according to actual conditions. If the coded data is larger than 63 characters, the data can be split into multiple levels of domain names. The first sub-domain name of the multi-level domain name may be as follows: abcde12345.Uvwxyz.67890.
Step S103, combining the first sub domain name as the prefix of the second sub domain name with the second sub domain name to form a domain name query request; wherein the second sub-domain name is the domain name of the software update server.
In the embodiment of the invention, a software update server needs to start a DNS query service of a local domain, taking update.dbapp.com as an example, and registers the DNS query service of an update.dbapp.com sub domain name to the dbapp.com domain. Step S102 and step S103 are used to construct a domain name query request. Specifically, the first sub-domain name in step S102 is used as the prefix of the second sub-domain name to be combined with the second sub-domain name, so as to form a domain name query request. The domain name query request may be abcde12345.Uvwxyz.67890.Update. Dbapp. Com as follows.
Step S104, a domain name query request is sent to the software update server, so that the software update server determines a query result of the software to be detected according to the domain name query request.
In the embodiment of the invention, a domain name query request is initiated, namely, a DNS query request is initiated, the domain name query request (for example, abcde12345.Uvwxyz. 6789. Update. Dbapp. Com) is submitted to a DNS server defaulted by a DNS system, and after being forwarded through DNS multi-level resolution, the domain name query request reaches the update. Dbapp. Com, namely, a software update server.
The DNS multi-level analysis is DNS recursion analysis, the DNS recursion analysis process is automatically completed by a DNS system, and the DNS recursion analysis process is as follows: step 1, a client sends a domain name query request (the website to be queried is www.abc.com) to a local DNS server; step 2, the local DNS server can not inquire the inquiry result corresponding to the inquiry request, and the inquiry request is forwarded to the root domain on the Internet; step 3, the root domain returns the server IP address of the top domain (the top domain of www.abc.com is com) in the domain name to be queried to the local DNS; step 4, the local DNS sends a query request to a top-level domain (com domain) according to the returned server IP address; step 5, the top-level domain server (com domain) returns the server IP address of the secondary domain (abc in www.abc.com) in the domain name to the local DNS; step 6, the local DNS sends a query request to the secondary domain; and 7, continuously repeating the operation until the local DNS server obtains a final query result and returns to the host computer so that the host computer accesses the website through the domain name.
The software update server determines the query result of the software to be detected according to the domain name query request, for example: taking the domain name query request abcdec 12345. Uvwxyz.6789. Update.dbapp.com as an example, the software update server removes the domain name update.dbapp.com of the software update server itself in the domain name request, and the obtained abcdec 12345.Uvwxyz.6789 is the query object to be actually analyzed, and restores the query result of the software to be detected, where the query result includes but is not limited to: software version number of the software to be detected and the characteristic information of the environment where the software to be detected is.
If the software to be detected is controlled by the authorized license, the software update server further checks and checks the software serial number and the hardware characteristic data so as to ensure that the query result of the software to be detected is not illegally used.
Step S105, receiving the query result, and analyzing the query result to obtain the software version upgrading information.
In the embodiment of the invention, the query result is a DNS query result, and the query result is decoded and the validity thereof is checked after the query result is analyzed. The software updating server returns the query result in the form of DNS query result, and selects the output form of the query result according to the data size of the query result. If the data size is smaller (i.e. the length of the character string of the query result is not greater than 40), the data size can be directly packaged into an IPv4 or IPv6 address, for example, the software version number provided by the software to be detected is 3.0.4.3, the software version number to be updated in the query result is 3.0.5.15, and the data size can be directly returned to 3.0.5.15 in the form of the IPv4 address; if the data size is large, the query result may be returned in a TXT manner, where the manner conforms to type=16 in the DNS specification, i.e. the query result is of the TXT TYPE. The diversified subsequent processing can be realized by setting different forms of query results, and if the query result is a URL, the client can access the appointed software update resource package according to the URL. The form of the query result comprises: the package is of an IP address or TXT type, so that the form of the software version upgrading information obtained by analyzing the query result also comprises: encapsulation is of the IP address or TXT type.
The software to be detected analyzes the DNS query result, and the analysis is completed at the client side and is used for judging the completeness and the effectiveness of the query result: if the query result is the encoded data, decoding the encoded data during analysis; if the query result is the encrypted data, the encrypted data is decrypted in the parsing process. The query result returned by the software update server may be the software version number to be updated after parsing, or may be the upgrade URL returned in the TXT type, or a credential of the upgrade package to be downloaded.
The embodiment of the invention provides a software version upgrading method based on DNS inquiry, which is applied to a client and is used for acquiring characteristic information of software to be detected; then, the characteristic information is subjected to coding processing to obtain a first sub domain name; combining the first sub domain name as the prefix of the second sub domain name with the second sub domain name to form a domain name query request; wherein the second subdomain name is the domain name of the software update server; sending a domain name query request to a software update server so that the software update server determines a query result of the software to be detected according to the domain name query request; and finally, receiving the query result, and analyzing the query result to obtain the software version upgrading information. According to the embodiment of the invention, under the condition that TCP connection is not established, the related characteristic information of the software to be detected is sent to the software update server for inquiry in a DNS inquiry mode, so that the software version information and the data required by the update version are acquired, the network overhead required by software update checking is reduced, and the method has certain advantages in the application environment of frequent update version.
Further, referring to fig. 2, step S102 may include the steps of:
step S201, coding the characteristic information to obtain a character string corresponding to the characteristic information;
step S202, judging whether a character string has preset sensitive information or preset special symbols;
in step S203, if the character string has preset sensitive information or preset special symbols, the character string is normalized to obtain a first sub domain name.
In the embodiment of the present invention, the preset sensitive information includes, but is not limited to: customer name, contract number, and software serial number. Preset special symbols include, but are not limited to: other symbols than numerals and letters are unexpected. If the character string does not have preset sensitive information or preset special symbols, the character string can be used as a first subdomain name for carrying out the next operation. If preset sensitive information or preset special symbols exist in the character string, standardized processing is needed.
Specifically, the normalization process includes, but is not limited to: a removal operation or a hash operation; step S203 may include the steps of: if the character string has preset sensitive information, performing removal operation or hash operation on the character string to obtain a first sub domain name; or if the character string has the preset special symbol, removing the character string to obtain the first sub domain name. The embodiment of the invention carries out the removal operation or the hash operation on the character strings with preset sensitive information, can realize the confidentiality of the preset sensitive information, and carries out the removal operation on the character strings with preset special symbols, thereby ensuring that the generated DNS query request is a correct domain name. For example, if a employee name is Zhang three and a job number is 1008, and if the two feature information are directly combined, the obtained combination of Zhang three 1008 cannot be directly used for inquiry because of containing Chinese characters, the Zhang three 1008 is encoded in a certain preset encoding mode, if the encoding mode is pinyin, the Zhang three 1008 is encoded to obtain a character string of Zhangsan1008, and if the job number is preset sensitive information, the character string is subjected to a removal operation to obtain Zhangsan or a hash operation to obtain Zhangsan 16ff9e7ebf ff51c265c21be35a6d4 b.
If the character string "zhang $san-! 1008', $ sum-! Belonging to preset special symbols, for character string' zhang $ san-! 1008 "performing a removal operation to obtain a first subdomain name" zhangsan1008".
The embodiment of the invention provides a software version upgrading method based on DNS query. The key points of the invention are feature information extraction, DNS query construction and query result analysis. The principle of the invention is that the present software version and the characteristics of the running environment of the software are sent to the software update server for verification through DNS inquiry, and the inquiry result is returned to the client in the mode of DNS inquiry result. Network overhead required by software update checking is reduced, and the method has certain advantages in application environments with frequent update versions.
