As the basis of all the system usage, the user must call the user login interface to log in the user, and can perform other operations after successful login.
Specifically, the login information of the user includes: user ID, user status, Token, and heartbeat time.
Further, the user states include: disable, lock, IP disable, and login period disable.
Specifically, the checking of the user login includes: the method comprises the following steps of checking a logged user and a logged-in user, wherein the checking of the logged-in user comprises the following steps: the login password of the user is verified, and the verification of the user who does not log in comprises the following steps: and checking the user name and the login password of the user.
And when the user logs in, the client locks the current logged-in user, only checks the password of the user, and does not need to verify the password of the user to the server. When the user does not log in, the client does not need to carry out a standard user login process, and only needs to verify the user name and the password.
When the user logs off, the client notifies the user name to the server, the server completes the log-off operation, and a successful result is returned to the client.
Specifically, the user login comprises three conditions, namely login operation is carried out on a logged-in user to verify the login state of the user; secondly, login operation is carried out on the logged-in user so as to verify the user name and the password of the user; and thirdly, performing login operation on the client side where the existing user logs in so as to enable a new user to perform preemptive login.
Furthermore, the server is based on the RBAC design mode, the role model of the server limits the roles by adopting a design mode of cardinality constraint and role mutual exclusion so as to ensure the accuracy of the permissions, and the permissions have transitivity in the unified model of the roles so as to ensure the effectiveness of the permissions. Wherein, the role includes: system administrators, system auditors, system configurators, administrators, users, and/or visitors.

Specifically, the method includes the steps of function menus in an automation system, button controls on an interface, modification of a database, file editing, left and right mouse button operation implementation and the like.
Specifically, the client can only keep one user online; and after receiving the user information logged in other clients, the server returns invalid login information to the currently logged-in client.
Further, the user management rules are: one machine only has one user online, the same user can only log in on one machine (the login is judged to be invalid on the other machine), the server side is provided with an enabling mark, the machine name/IP is automatically transmitted by a communication link without being processed by a client side, only part of applications (a control panel, online monitoring and the like) can log in, and the rest of the applications intelligently execute the verification function.
Specifically, the service interface of the service end includes: a service interface with an interface and a service interface without an interface; the service interface without the interface comprises: user authentication, user logout, current user acquisition, judgment whether the user has a designated legal authority, password modification, error reason acquisition, current process unique mark acquisition, current user IP white list acquisition, current user responsibility partition list acquisition, role information list acquisition, user information list acquisition under a certain role and/or a start/stop check token. The service interface with interface includes: pop-up user login window, pop-up user authentication window, pop-up user logout window, pop-up user modified password window, and/or pop-up guardian authentication window.
In the technical solution, a design process of a user management device includes:
1. server module development and deployment
The server module is used as an authentication service module for user management, and meets various authentication requirements of the client, such as user name and password verification, authority verification and the like. And the service end carries out distributed deployment, and the ICE bridge carries out service discovery through IP + PROT and determines a main service process. The present invention is described with respect to functional verification logic for a client. The client and the server communicate through an ICE bridge to realize distributed deployment. The server and the client communicate through the ICE bridge.
2. Client module development and deployment
The service interfaces provided by the client to the outside are divided into interfaces with interfaces and interfaces without interfaces. The service without the interface comprises the functions of user authentication, user logout, current user novelty acquisition, judgment on whether the user has a designated legal right, password modification, error reason acquisition, current process unique mark acquisition, current user IP white list acquisition, current user responsibility partition list acquisition, role information list acquisition, user information list acquisition under a certain role, token starting/stopping verification and the like. The service with interface includes popping up user login window, user verification window, user logout window, password modification window and guardian verification window.
3. As the guarantee of the security, when any module or subsystem in the system is operated or modified, the user logs in so as to facilitate the audit log record, the operation history record and the like in the later period. The standard user login process is that the client side checks the non-null and length of the user name and the password, first judgment is carried out according to the returned result of the user authority, and the server side carries out user login information verification after the authority passes.
The verification sequence is as follows: and if the current user authentication result is that the user is locked/disabled/IP disabled/login period disabled, returning authentication failure and requiring to replace the user. And then, carrying out user password verification, if the user password is mistakenly returned, and locking the current user when the password is mistakenly returned for a certain number of times. After the password passes the verification, whether the user logs in for the first time or the password validity period expires is judged, if the user is required to change the password, a new password validity period can be set only after the password is changed, and the user is allowed to log in.
The user can call the corresponding interface according to the self service requirement. Other operations of the system may be performed only if the interface verification returns a success.
The following objects are defined in step 1: rights resource, user, role, group. In the substation automation system, a menu, a button, equipment and a partition can be regarded as resources and are distinguished through resource types. Intangible operational controls may also serve as a privilege resource. The specific operator of the application system, the user obtains different authority information by endowing different roles. In order to classify and manage a plurality of users with similar permissions, the concept of roles is defined, such as roles of system administrators, system auditors, system configurators, administrators, users, visitors and the like. In order to better manage users, the users are grouped and classified, groups have a top-bottom relationship, and a tree view can be formed. The mutual exclusion of the authority is configured by a system configurator, the exclusive authority cannot be granted to the same role, and when different roles are granted to the same user, whether the exclusive authority is included is checked firstly.
In consideration of general design, user roles, roles and resources are in a multi-to-multi relationship, permissions among different roles in one user are mutually exclusive in access control requirements in safety specifications, requirements that the same user cannot be granted to the same role can be achieved by adding background filtering conditions, and the background service maintenance relationship is still in a multi-to-multi relationship, so that services can be reused when service requirements are changed later.
By the method, different tools in the operation period, the configuration period and the configuration period in the automatic system of the transformer substation can adopt the same user management module, and the permission resources only need to be expanded according to different services. Therefore, the development period of the tool can be shortened, only one set of basic service module needs to be maintained, the maintenance cost is reduced, and unified management is facilitated.
