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.
Currently, how to efficiently and safely operate and manage a plurality of online servers is an important problem for an internet company having the servers. For most of the existing on-line servers, besides an internal network address and an external network address, an independent power supply physical module is generally provided to ensure that operation and maintenance personnel can log in the on-line server to perform operations such as restarting and shutdown under any condition. Most remote management cards support role division and authority division, but in practical application, the number of online servers is large, the number of operators is also large, and a lot of manpower is consumed for setting the authority for each server, so that the authority is difficult to realize, therefore, most enterprises using the remote management cards do not perform role division and authority control, and the operators have all authorities.
Fig. 1 is a flowchart illustrating a user applying for logging in a server in the prior art.
When a user wants to log in the server, login request information is sent to the remote management card to apply for login.
And 102, receiving login request information sent by a user by the remote management card, and allowing the user to log in the server.
And receiving login request information sent by a user and confirming whether the user can log in, wherein if the user has login authority, the user can directly log in the server and control and manage the server. At present, a remote management card does not perform role division and authority control on users, and all users applying for logging in a server have authority to log in the server, control and manage the server. Meanwhile, the memory and the storage space of the remote management card are extremely small, and manufacturers are difficult to enlarge the memory and the storage space in a customized mode due to the consideration of the cost of a production chip, so that only a small amount of log logs can be recorded, and if the remote management card is attacked, operation and maintenance personnel are difficult to find the attack source.
When all operators have operation authority and the remote management card cannot store more log logs, serious potential safety hazards are brought to the use of the server.
In order to eliminate the potential safety hazard in the prior art, the embodiment of the invention discloses a method and a system for login management of a server remote management card, which are respectively described in detail below.
Referring to fig. 2, fig. 2 is a flowchart of the login management of the server remote management card according to the embodiment of the present invention, which includes the following steps:
In this step, when the user wants to log in the online server to control and manage the server, the user needs to log in through the remote management card. The user sends a login request to the remote management card, and the remote management card receives login request information sent by the user. Specifically, the login request information sent by the user may include an account number, a password, a job number, and the like, but is not limited to any one of them.
In this step, an access control manager is introduced, and the access control manager is usually used as a tool for uniformly managing the related authority of the company employees. After receiving the login request sent by the user, the remote management card sends an authority query request to the access control manager, wherein the authority query request comprises the user information of the user.
Optionally, the user information of the user includes at least one of a department to which the user belongs, a job number of the user, an IP address of the user, and a position of the user.
The login authority of the user refers to whether the user has the authority to log in the server or not, and further comprises the operation authority which can be performed. For example, add, delete, check and modify, etc. The access control manager can open different operation authorities according to information such as the department to which the user belongs, the position of the user and the like.
The access control manager determines the login authority of the user according to the received authority inquiry request, wherein the user information of the user is included. After the access control management determines the login authority of the user, the user can quickly feed back to the remote management card to determine whether the current user has the authority to login.
Optionally, if the access controller already stores the pre-authorization information of the user, the remote management card may quickly determine the login authority of the user according to the pre-authorization information, and allow or deny the user to log in the server.
Optionally, if the login authority of the user is not stored in the access controller, the access controller determines the login authority of the user according to the user information of the user, pre-authorization information of all users capable of connecting to the server is stored in the access controller, and the pre-authorization information of the user corresponds to the login authority of the user. The remote management card pre-authorizes a user in the access controller according to at least one of a department to which the user belongs, a job number of the user, an IP address of the user and a position of the user, determines the authority which can be opened, such as operation authority for deletion, restart, modification and the like, and when the user applies for login, the remote management card can quickly determine the authority according to the pre-authorization condition.
When a user applies for login to the remote management card, the remote management card sends an authority inquiry request to the access controller and simultaneously carries out caching, and when the user leaves the remote management card, related caching information does not need to be reserved. In this process, the access control manager can store the inquiry request of the remote management card, although the remote management card still cannot record enough data.
And step 205, the remote management card manages and controls the user to log in and manage the server according to the login authority of the user.
When the access control manager sends the login right of the user to the remote management card, the remote management card allows or rejects the login request of the user according to the right content and limits the right. For example, when the user has login authority, the remote management card receives the login authority sent by the access control manager and allows the user to log in, and after the user logs in, the user can access the server to realize management and control of the server.
Therefore, the embodiment of the invention manages the login method of the remote management card by introducing the uniform access control manager, realizes clear role division and authority control, and when a user applies for logging in the server, the access control manager and the remote management card work in combination to manage the operation authority of the related user, thereby ensuring the safety of the server.
When the user does not have the login right and applies the login right to the remote management card, the remote management card authorizes the user according to the user information of the user. The authorization process is as follows:
referring to fig. 3, fig. 3 is a flowchart illustrating a remote management card authorizing a user according to an embodiment of the present invention.
When the user does not have the right to log in the server, the user applies the login right to the remote management card.
In the specific embodiment of this step, the method further comprises the following steps:
In this step, before the user applies for login, the remote management card pre-authorizes all the personnel in the access control manager according to the user information, so that the remote management card can quickly determine the login authority of the user according to the pre-authorization condition. For example, when an old employee applies for a login to the server, the information has been stored in the access control manager and the remote management card has pre-authorized the employee, so the remote management card can quickly determine the login rights of the employee.
When the user information of the user who applies for login is not stored in the access control manager, for example, when a new employee applies for login, the access control manager determines the login authority of the user according to at least one effective information of department, job number, IP address, position, etc. to which the employee belongs, i.e. whether the user has the right to login the server. The login authority also includes an operation authority that the employee can open, such as which operations can be performed on the server.
As can be seen, in this embodiment, for all users applying for logging in to the server, when the pre-authorization information of the user is stored in the access control manager, the remote management card can quickly determine the login authority of the employee. And when the pre-authorization information of the user is not stored in the access control manager, the access controller determines the login authority of the user according to the user information of the user. The access control manager and the remote management card work together to realize authority control on all users and divide the authority of all users requesting to log in the server.
However, when the user applies for login, because the memory and storage space of the remote management card are extremely small, a large amount of login request data cannot be recorded, when the user leaves the remote management card, the access control manager can record all query requests of the remote management card although the remote management card does not keep relevant records, and a basis is provided for searching the request records in the future. The process of the access control manager generating the authority query request log will be described below.
Referring to fig. 4, fig. 4 is a flowchart of an access control manager generating an authority query request log according to an embodiment of the present invention.
When a user applies for logging in a server to the remote management card, the remote management card not only sends an authority inquiry request to the access controller, but also caches a log, and when the user leaves the remote management card, related cache information does not need to be reserved. The remote management card has extremely small memory and storage space and cannot record enough data. But in this process the access control manager can store the request for the right inquiry of the remote management card.
The access control manager may record a large amount of data, store the authority query requests of all users, and generate an authority query request log. The method is convenient for searching the attack source according to the authority inquiry request log generated by the access control manager if the remote management card is attacked in the future, and provides a basis for eliminating potential safety hazards.
Therefore, the operation authority of the user can be divided and controlled by introducing the access control manager, the management efficiency of the server remote management card is improved, a large amount of login request information can be recorded, a login request log is generated, when the remote management card is attacked in the future, an attack source can be searched by searching the login request log, and a basis is provided for solving the safety problem of the server.
Fig. 5 is a schematic structural diagram of a system according to an embodiment of the present invention, and as shown in fig. 5, the system includes: a remote management card 501 and an access control manager 502; wherein the content of the first and second substances,
the remote management card 501 is configured to receive login request information sent by a user, send an authority query request to the access control manager 502, and manage and control the user to log in and manage a server managed by the remote management card according to the login authority of the user;
the access control manager 502 determines the login authority of the user according to the user information of the user, stores the login authority of all users having authority to login the server, sends the login authority of the user to the remote management card 501, and stores the authority query request.
Further, the access control manager 502 is configured to determine the login authority of the user according to the user information of the user if the login authority of the user is not stored, where pre-authorization information of all users that can connect to the server is stored in the access control manager, and the pre-authorization information of the user corresponds to the login authority of the user.
Further, the access control manager 502 is further configured to obtain user information of all users capable of connecting to the server, where the user information includes at least one of a department to which the user belongs, a job number of the user, an IP address of the user, and a position of the user; and determining pre-authorization information of all users capable of being connected with the server according to user information of all users capable of being connected with the server, wherein the pre-authorization information comprises the authority of the users for logging in the server and the management and control authority of the users for the server.
Further, the access control manager 502 is further configured to generate an authority query request log according to the stored multiple authority query requests.
Further, the access control manager 502 sends the login right of the user to the remote management card 501 through an LDAP protocol packet.
The server remote management card login management system provided by the embodiment of the invention can realize role division and authority control on all users applying for login of the server, and the access control manager can also store all authority inquiry requests to generate the authority inquiry request log, so that when the remote management card is attacked in the future, the attack source is searched by searching the authority request log, and the safety in server management is improved.
