In a database I am designing I have implemented profile based object level security.
Each user can view, edit, insert, update database tables according to the profiles (roles) he is a member of.
Now there is a need to implement "External Users" who can view only the relevant records and edit some of them (but not the bulk of the database).
I am working on an "record ownership" model.
Are there any ideas on how to restrict the users belonging to an "External Users" profile to see and work with some records of each table, but not all.
You should probably create a VIEW which limits the records and then apply the proper rights on the view.
You could create a VIEW, or you could create select stored procedures and only assign rights to those.
The VIEW is the way to go for a simple security model - if it is complex, go with the stored procedure(s).
I have my first draft. It goes like that:
The app is a Project Management/Issue Tracking/Event Management/Collaboration Web app.
I created a Role "External User". By default a user in that role
can SELECT FROM Persons
can SELECT FROM Units (organizational units-companies-depts etc)
can SELECT Projects assigned to him
can SELECT Tasks assigned to him
can not SELECT any other Projects & Tasks
The administrator can create a user group "External Partner" and assign to that some Projects and Products (with Issues)
The members of this group can SELECT the assigned Objects.
It is a complicated solution, but the only one that solves my customers problem (they don't want external partners to have access to all their project database).

Suppose I have 2 users available for the same project. The requirement is to restrict the table access in the same project to one user. How can it be managed it in Bigquery? what kind of access controls to be applied and how?
Thanks in advance.
You can use table level ACLS and set Bigquery roles/bigquery.dataViewer for users on the tables you wish to grant access. More details here https://cloud.google.com/bigquery/docs/table-access-controls-intro
This approach doesn't require creating a separate dataset(as a workaround for table level access) for access control which use to be the case earlier.
Depending on requirements, and the strictness of them, this is what I do:
Grant the user access to a specific table within a dataset by granting the BigQuery Data Viewer role at the table level.
You can do this as follows:
-> Open the table in the console and click Share, then click Add Principal
And to make it easier for the user to navigate the metadata of the table, such as schema, details and preview, I grant them the BigQuery Metadata Viewer role at the dataset level.
You should only do this of course if it is ok for the user to see which other tables within the dataset are there. (they can't see the data in the other tables, just the schema etc)
The advantage is that it will be easier for the user to see the schema and a preview of the data.

I have a dimension which contains our business warehouse IDs and also I made users in Active Directory with the same name(1001, 1002, 1003, 1004, …) as you see in below.
DimWarehouse
ID
1001
1002
1003
1004

My question is that how it is possible each "username" just access to it's Warehouse ID?
There are two ways how you can restrict user access to certain parts of the cube:
You define "static security": You define one role in the cube for each set of permissions (if I understand your requirements correctly, that would mean one role per user), and then you map the Active Directory users or user groups to those roles. If you have many users and many permission roles, that can get more or less unmanageable. However, sometimes it is good that you also can use AD user groups for this purpose, and that can reduce effort a lot. I Implemented a solution like this where we needed to restrict access user access based on their country, and only had around 50 countries, and AD user groups were already existing for the countries.
You can use "dynamic security". This means you only use a single role and write an MDX expression that most likely makes use of the Username() MDX function, and which returns a valid MDX set which is either a set of allowed or a set of forbidden members. As your MDX statement could even call an AS Stored procedure implemented in .net, you are even more flexible, as this .net Stored procedure could e. g. contact your AD to check for further properties of the user.
In both cases, you would administer the settings in "dimension security" of the cube design in "SQL Server Data Tools - Business Intelligence" or in SQL Server Management Studio, and would need to design your cube accordingly to have the correct relations from the dimension that you restrict to your data.
A detailed (if a bit old) blog post describing an approach for setting security using dynamic security can be found at http://bharathonsqlserver.blogspot.com/2016/07/dynamic-security-in-ssas-in-detail.html.
The permissions are driven by roles.
You may need to create multiple roles and assign users to each of the roles.
Then for each role, you define which dimension attributes are accessible to that role.
I am new to HANA Database. I am just trying to create new User in HANA DB through Eclipse systems editor. I have selected only below role as part of user creation.
sap.hana.xs.lm.roles::Developer
But, it is showing below roles as a result of executing query select role_name from "PUBLIC"."EFFECTIVE_ROLES" where USER_NAME = 'TEST_USER';
ROLE_NAME
PUBLIC
sap.hana.xs.lm.roles::Developer
sap.hana.uis.db::SITE_USER
sap.hana.xs.lm.roles::Display
sap.hana.xs.lm.pe.roles::PE_Display
Why being added other roles to user even not selected?
Roles in SAP HANA are collections of privileges and other roles.
This can lead to a situation where a role contains several other roles, each of which can contain other roles and privileges. That way you have a hierarchy of direct and indirect role- and privileges assignments to a user account.
The system view you query is EFFECTIVE_PRIVILEGES. It’s single most important function is to unroll all roles that have been assigned directly and indirectly (effectively going through the roles-privileges-hierarchy) and to return all those assignments.
This “unrolling” of hierarchical structures is not easy/efficient to do in plain SQL, so this system view provides this special feature as a built-in functionality.
The pre-defined role sap.hana.xs.lm.roles::Developer contains several other roles (as your query result shows).
To double-check you can even review the role definition in the HANA XS repository by navigating to thesap.hana.xs.lm.roles package, as this role is delivered as a design-time artefact.
If you actually only want to see the direct assignments of roles/privileges to a user (or to roles), using system views GRANTED_ROLES or GRANTED_PRIVILEGES will get you that.
I am trying to create a new level of user which is like an admin but has less credentials. He cant configure settings of the modules but can view, add, edit, delete data of the employees. Thanks in advance.
There is hidden "User Roles" module in OrangeHRM, it provides you all the permissions required to change/assign particular menu items to various roles. This needs some custom work such as updating the values on check/uncheck but should be a simple job to do. And tables names are shared by #patxrick should help you to do the modification easily.
You need to insert new user role in ohrm_user_role table.
Then add related records in tables like ohrm_user_role_screen table and ohrm_user_role_data_group.
I am looking for the best way to setup an Oracle database so that multiple roles can share a single schema with tables.
I would have, for example, several roles:
Application User
N Developer Users
DBA User
... future user types
I have been able to create groups, grant privileges to other schemas, and create a logon trigger to switch the schema on logon. However, users are not able to view tables through SQL Developer.
SQL Developer will only show the objects owned by the current user, not those that are owned by the session's current_schema setting, in the tree view unless you go to Other Users and choose the schema you're interested in. In order to see objects owned by other users, you're realistically going to have to navigate to the appropriate schema. If there are a large number of schemas in the database, you can right click on Other Users and create a filter that limits the set of users that are returned to just the schema you care about.
