Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The password for the database to perform password authentication on the application program is one of key elements for maintaining information security, and the password of the database needs to be modified periodically in order to ensure the information security. In the modification process of the database password, if the application system provides services for the user normally, the application program responds to the operation of the user, needs to call the user name and the password stored in the configuration file to request password authentication from the database and log in the database, and at this time, the password of the database may have been modified, and the modified password is not synchronized into the configuration file of the application program, so that the password authentication of the application program fails and the application program cannot log in the database normally. Therefore, when the database password is modified, the operation of the application system is usually required to be stopped, which affects the normal use of the user, and especially when the database has access relations with a plurality of application programs, the task of completing the password modification takes a long time, which results in that the application system cannot provide services normally for a long time. Secondly, in actual operation, in order to avoid the loss caused by the fact that the user cannot normally use the application system, the modification frequency of the database password is often reduced, and the requirement of information security is not met.
Therefore, the embodiment of the invention provides a method for modifying a database password, which enables an application program needing to access a database to request identity authentication from a third-party system to log in the database in the process of modifying the database password. The method can meet the requirement that the application program logs in the database password modification process without stopping the operation of the application system, so that the user experience is prevented from being influenced by stopping the operation of the application system.
The embodiment of the invention provides a method for modifying a database password, which can be applied to a third-party system, wherein an execution main body of the method can be a processor in an application system or a peripheral processor for executing a function corresponding to the method, and a flow chart of the method is shown in fig. 1 and comprises the following steps:
s101: under the condition that the password of the database needs to be modified, triggering a target application program to log in the database in a mode of identity authentication to a third-party system, wherein the target application program is an application program for accessing the database in the process of modifying the password of the database;
in the method provided by the embodiment of the invention, under the condition that the third-party system responds to the information security requirement and needs to modify the database password, the authentication mode of the database is changed, so that the database authenticates the application program in a non-password authentication mode. In the process of modifying the password of the database, when the application program requests to log in the database in a password authentication mode, the application program is triggered to request identity authentication from the third-party system so as to log in the database in a third-party system identity authentication mode. The current authentication mode of the database can be obtained by sending an authentication mode query instruction to the database, or a successful change response can be sent to a third-party system by presetting and triggering the database after the authentication mode is changed. When the database authenticates the application program in a non-password authentication mode, the modification work of the database password is started.
S102: randomly generating a target password, and modifying the current password of the database into the target password;
in the method provided by the embodiment of the invention, under the condition that the database does not perform identity authentication on the application program accessing the database by password authentication, the target password can be randomly generated based on the preset password generation script, for example, the password can be generated by a function for generating a random number, the password can be randomly generated by calling a preset password generator, and the target password meeting the security requirement can be obtained by controlling the generation type of data, such as generating random numbers or letters. After the target password is generated, the user name of the database and the current password can be called according to a preset password modification script, a command of modifying the password corresponding to the database is executed, the user password of the target database is modified, and the user password is modified into the target password. For example, in the MySQL database, the command "MySQL > setpassword for user name @ localhost ═ password ('change password')" may be used to modify the password, or "MySQL in-u user name-p original password change password" may be used, or the user table may be used to modify the password of the database directly by UPDATE.
S103: when the current password of the database is successfully modified into the target password, determining a configuration file of each application program in an access relation with the database, and modifying the current password of the database pre-stored in each configuration file into the target password;
in the method provided by the embodiment of the invention, after the current password of the database is modified, the configuration file of the password for password authentication stored in each application program in the access relation with the database can be determined through the information of each application program which is stored in the database in advance and has the access relation with the database, the configuration file of the application program is called according to a preset configuration modification script, and the database password for password authentication stored in each configuration file in advance is modified into the target password according to a preset data modification command.
S104: and when the current password of the database stored in each configuration file in advance is modified into the target password, triggering the database to carry out identity authentication on each application program accessing the database in a password authentication mode.
In the method provided by the embodiment of the invention, after the database passwords which are pre-stored in the configuration file of each application program in the access relation with the database and are used for password authentication are modified into the target passwords, the database can be triggered to change the identity authentication mode of the application program accessing the database, so that the database can continuously perform identity authentication on each application program accessing the database in the password authentication mode.
Based on the method provided by the embodiment of the invention, under the condition that the password of the database in the system needs to be modified, the application program accessing the database in the password modification process is triggered to carry out identity authentication on the third-party system, so that the database is logged in a third-party system identity authentication mode. Under the condition that the database does not perform identity authentication on the application program accessing the database by password authentication, the target password can be randomly generated, the password of the database is modified into the target password, and the target password is synchronized into a configuration file of the database password for password authentication stored in each application program in an access relation with the database, so that the modification of the database password is completed. After the password of the database is modified, the database can be triggered to perform identity authentication on the application program accessing the database in a password authentication mode. The method provided by the embodiment of the invention can complete the modification of the database password and ensure the information security of the database. During the process of modifying the data password, the application program accessing the database can request identity authentication from the third-party system to log in the database, and the database does not need to perform identity authentication on the application program in a password authentication mode. In the modification process of the database password, the database and the application program accessing the database do not need to call the password to realize the requirement that the application program logs in the database. The user password for modifying the database can not interfere the identity authentication process of the application program for logging in the database, so that the login failure is caused. Therefore, in the process of modifying the database password, the application program can log in the database to obtain data, normally respond to user operation, and does not need to suspend external service of the application system, so that the use experience of the user is improved. Secondly, the method provided by the embodiment of the invention can call the script to modify the database password and uniformly modify the password in the configuration file of the application program, thereby saving human resources and improving the modification efficiency. The randomly generated password is used as a new password for modification, so that the possibility of password leakage is reduced, and the information security of the database is further ensured.
To better explain the method provided by the embodiment of the present invention, referring to fig. 2, on the basis of the method shown in fig. 1, a further method for modifying a database password is provided, where in step S101 shown in fig. 1, the process of triggering a target application to log in a database in a manner of performing identity authentication with a third-party system is described, and the method provided by the embodiment of the present invention includes:
s201: sending a first authentication change instruction to the database to indicate that the database triggers the target application program to send a preset digital certificate to the third-party system to request identity authentication when receiving a login request sent by the target application program;
in the method provided by the embodiment of the invention, the first authentication change instruction can be sent to the database of which the password needs to be modified under the condition that the third-party system needs to modify the password of the database according to the information security requirement. The modification period of the database password can be determined according to factors such as the life cycle of information stored in the database or the information security level, and an authentication change instruction can be sent to the database when the preset modification period of the database password is triggered according to a preset script. And when the actual demand is changed unplanned greatly, according to the actual information security demand, when the password of the database needs to be modified, the manager triggers the system to actively send an authentication change instruction to the database.
When the database receives a first authentication change instruction sent by a third-party system, the identity authentication mode of the application program accessing the database can be changed, and the application program is not authenticated in a password authentication mode any more. Under the condition that the database is not authenticated in a password authentication mode, if the database receives a login request sent by an application program in the password authentication mode, a third party authentication instruction can be sent to the application program, and the application program is triggered to apply a preset digital certificate to request identity authentication to a third party system. When the application program receives a third party authentication instruction sent by the database, a preset digital certificate can be called, and an identity authentication request is sent to a third party system based on the digital certificate.
S202: when the digital certificate sent by the target application program is received, performing identity authentication on the target application program according to the digital certificate;
in the method provided by the embodiment of the invention, when the third-party system receives the digital certificate sent by the application program, the identity authentication can be performed on the application program according to the digital certificate. The identity of the application program can be authenticated by comparing the digital certificate sent by the application program with a trusted certificate pre-stored by a third-party system. For example, a unique digital identifier corresponding to the application may be included in the digital certificate, and the digital identifier may be stored encrypted in the digital certificate. When a digital certificate sent by an application program is received, a digital identifier corresponding to the digital certificate can be obtained through decryption processing. All pre-stored trusted certificates, i.e. digital certificates corresponding to applications that are in an access relationship with the database, may be obtained. And decrypting all the trusted certificates to obtain all the trusted digital identifications. And comparing the digital identifier corresponding to the digital certificate sent by the application program with all trusted digital identifiers to realize the identity authentication of the application program. Or all the trusted digital identifications can be stored in advance, and the comparison is directly carried out by acquiring the prestored trusted digital identifications and the digital identifications corresponding to the digital certificates of the application programs. And when the digital identification corresponding to the digital certificate of the application program is the same as any trusted digital identification, passing the identity authentication of the application program. Otherwise, if the digital identifier corresponding to the digital certificate of the application program is different from each trusted digital identifier, the application program does not pass the identity authentication.
S203: when the identity of the target application program is authenticated, generating an authentication identifier corresponding to the target application program;
in the method provided by the embodiment of the invention, when the third-party system passes the identity authentication of the application program, the corresponding authentication identifier can be generated for the application program passing the identity authentication. For example, an identity corresponding to the application program may be obtained, a corresponding token is generated based on the identity, and the token is used as the identity corresponding to the application program. And a corresponding authentication identifier can be distributed to the application program passing the identity authentication through a preset script.
S204: and respectively sending the authentication identification to the database and the target application program, and triggering the target application program to apply the authentication identification to carry out identity authentication on the database so as to log in the database.
In the method provided by the embodiment of the invention, after the third-party system generates the corresponding authentication identifier for the application program, signature encryption can be carried out on the authentication identifier, and the authentication identifier after signature encryption is respectively sent to the database and the application program requesting identity authentication. After the application program receives the authentication identifier sent by the third-party system, a login request can be sent to the database based on the authentication identifier so as to log in the database.
When the database receives a login request sent by the application program based on the authentication identifier, the authentication identifier sent by the application program can be acquired, the authentication identifier sent by the application program is compared with all authentication identifiers sent by a third-party system and received by the database in advance, and if the authentication identifier sent by the application program is the same as any authentication identifier received by the database in advance, the application program can log in the database to perform corresponding operation through the login request of the application program. Otherwise, if the authentication identifier sent by the application program is different from each authentication identifier received by the database in advance, the login request of the application program is not passed. For example, when the generated token is used as the authentication identifier, when the database receives the token sent by the application program, the token may be decrypted, the token sent by the application program may be compared with all the token tokens received in advance and sent by the third-party system, for example, the identity identifiers in the token tokens may be compared, and if the identity identifier in the token sent by the application program is the same as the identity identifier in any one of the token tokens received in advance, the authentication request of the application program is passed. The signature and the timestamp in the token may be further compared, and if the identity, the signature, and the timestamp in the token sent by the application are the same as the identity, the signature, and the timestamp in any token tokne received in advance, the login request of the application is passed.
Based on the method provided by the embodiment of the invention, the authentication change instruction can be sent to the database under the condition that the password of the database needs to be modified, so that the database triggers an application program accessing the database in the password modification process to request identity authentication from a third-party system by adopting a preset digital certificate, and the application program logs in the database in a third-party system identity authentication mode. Under the condition that the database does not perform identity authentication on the application program accessing the database by password authentication, the target password can be randomly generated, the password of the database is modified into the target password, and the target password is synchronized into a configuration file of the database password for password authentication stored in each application program in an access relation with the database, so that the modification of the database password is completed. After the password of the database is modified, the database can be triggered to perform identity authentication on the application program accessing the database in a password authentication mode. The method provided by the embodiment of the invention can complete the modification of the database password and ensure the information security of the database. Further, in the method provided by the embodiment of the present invention, a digital certificate may be preset in an application program that is in an access relationship with a database, and in a modification process of a database password, the application program may request identity authentication from a third-party system using the preset digital certificate, and after the third-party authentication passes the identity authentication of the application program, a corresponding authentication identifier may be generated for the application program, and the generated authentication identifier is sent to the database and the application program, so that the application program may log in the database through the authentication identifier, thereby implementing that in the modification process of the database password, the application program that is in an access relationship with the database may normally log in the database in a non-password authentication manner to perform corresponding operations without stopping external services of the application system, and improving user experience. Secondly, in the method provided by the embodiment of the present invention, by presetting a digital certificate in an application program having an access relationship with a database, the application program can request identity authentication from a third-party system by using the digital certificate to log in the database, and the application program having no access relationship with the database does not have a preset certificate, and cannot log in the database by using the identity authentication of the third-party system even during the modification of a password of the database, and the digital certificate is more conveniently replaced, so that the digital certificate can be timely replaced within a preset period or when the access relationship between the database and the application program changes, thereby further ensuring the information security of the database. Further, in the method provided by the embodiment of the present invention, the password modification period of the database may be preset, and when the password modification period is triggered, an authentication change instruction is sent to the database to modify the password of the database. By setting the password modification period to trigger the password modification process, the problem that the information safety of an application system is influenced due to the fact that the password modification frequency is reduced due to artificial reasons when a worker triggers the password modification process of the database can be avoided. Therefore, the safety of the database information is further improved.
Further, to better explain that in the method shown in fig. 2, in step S203, the authentication identifier corresponding to the target application is generated, a further method for modifying a database password is provided in the embodiment of the present invention, and on the basis of the method shown in fig. 2, a process of generating the authentication identifier corresponding to the target application in the method provided in the embodiment of the present invention includes:
determining the application equipment where the target application program is located;
in the method provided by the embodiment of the invention, after the third-party system passes the identity authentication of the application program, the application equipment where the application program passing the identity authentication is located can be determined. For example, corresponding setting may be performed in advance, so that when the application program sends the identity authentication request to the third-party system by using the preset digital certificate, the application device information where the application program is located is written in the identity authentication request information, and the application device where the application program passing the identity authentication is located may be determined by receiving the application device information in the identity authentication request information. Or after passing the identity authentication request of the application program, sending a device information request to the application program to acquire the application device information of the application program sent by the application program, so as to determine the application device of the application program.
