How to implement row level security using external tables

Hi All Gurus/ Masters,
I want to implement row level security using external tables, as I'm not sure how to implement that. and I'm aware of using it by RPD level authentication.
I can use a filter condition in my user level so that he can access his data only.
But when i have 4 tables in external tables
users
groups
usergroups
webgrups
Then in which table I need to give the filter conditions..
Pl let me know this ...

You pull the Group into a repository variable using a session variable init block, then reference that variable in the data filters either in the LTS directly or in the security management as Filters. You reference it with the syntax VALUEOF("NQ_SESSION.Variable Name")
Hope this helps

Implement row-level security using Oracleu2019s Virtual Private Databases (VPD)

Environment: Business Objects XI R2; Oracle 10g
Functional Requirement:
Implement row-level security using Oracleu2019s Virtual Private Databases (VPD) technology. The restriction is that the Business Objects Universe connection should use a generic/u201Capplicationu201D database user account. This will allow the organization to avoid the situation where the Business Objects password and the Oracle password need to be kept in synch.
What do we need from the Business Objects support team?
1.     Review the 2 attempted solutions that we have tried to implement
2.     Propose solutions/answers to open questions for each of the attempted solutions
3.     Propose any alternate solution that will help us implement the Function Requirement stated above
Attempted Solution 1: Connection String uses Oracle Proxy User
The connection string that is specified in the Universe is the following:
app_user[end_user]/app_user_pwdarrobaDatabase.WORLD
app_user = generic application user
end_user = the oracle account of the end user which is set using arrobaVariable('BOUSER') app_user_pwd = password of the generic application user
We have tried and implemented this in our test environment. However, we have some questions and concerns around how the connections are reused in a connection pool environment.
Open Question for Solution 1:
i. What happens when multiple proxy users try to connect on at the same time? Business Objects shares the generic app_user connect string. However, every user that logs on will have their own unique proxy user credentials. Will there be any contention involved? If so, what kind of errors can we expect?
ii. If a user logs on using his credentials (proxy user), and business objects opens up a connection to the database using that user's credentials (as the proxy user but logging in through the generic app user). Then the user exits out --> based on our test today, it seems like the database connection remains open. In that case, if another user logs on similarly with their credentials, will business objects simply assign the first users connection to that second user? If so, then our security will not work. Is there a way that Business Objects can somehow ensure that everytime we close a report, the connection is also terminated both at the BO and DB levels?
iii. Our 3rd question is general high level -> How connection pooling works in general and how it is implemented in BO, i.e. how are new connections assigned, how are they recycled, how are they closed, etc.
Attempted Solution 2: Using the ConnectInit parameter
Reading through a couple of the Business Objects documents, it states that u201CUsing the ConnectInit parameter it is possible to send commands to the database when opening the session which can be used to set database specific parameters used for optimization.u201D
Therefore, we tried to set the parameter in the Universe using several different options:
ConnectInit = BEGIN SYSTEM.prc_logon('arrobaVARIABLE('BOUSER')'); COMMIT; END; ConnectInit = BEGIN DBMS_SESSION.SET_IDENTIFIER('arrobaVariable('BOUSER')'); COMMIT; END;
Neither of the above iterations or any variation of that seemed to work. It seems that the variable is not being set or being u201Cexecutedu201D on the database.
One of the Business Objects documents had stated that Patch ID 38, 977, 350 must be installed in our BO environments. We have verified that this patch has been applied on our system.
Open Questions for Solution 2:
How do we get the parameter ConnectInit to work? i.e. what is the proper syntax to enter and what other things do we need to check to get this to work.
Note: Arroba word is being used instead of the symbol in order to avoid following error message:
We are sorry but your message can not be posted since you have included an email address. Please remove the email address and re-post.

the connectinit setting should look something like this:
declare a date; begin vpd_setup('@VARIABLE('BOUSER')'); Commit; end;
The vpd_setup procedure (in Oracle) should look like this:
CREATE OR REPLACE procedure vpd_setup (p_user varchar)IS
BEGIN
DBMS_SESSION.set_vpd( 'SESSION_VALUES', 'USERID', p_user );
END vpd_setup;
Then you can retrieve the value of the context variable in your vpd functions
and set the vpd.

How to implement row level security?

Hi all,
There is a database which is for 3 companies to use it and how to use row level security to make sure that they can only manipluate their own data? For example, "employee" table, for each company they just can see their own employees information. How to use dynamic view to do it?
Many Thanks
Amy

Here are two options to achieve what you want.
A. You can do this by coding, that's if you are ready to. Are you? If yes then try the steps below:
1. create a security codes table. Say for example
001 - company a
002 - company b
2. create a security table that will list all users and which company they should have access to. You can also implement this by roles.
3. alter all tables in the application schema to add a security code column. This will be a foreign key reference to table created in 1 above.
4. update all data in the tables according to which company they belong to.
5. write a procedure or package that does a validity check whenever a user requests for data. This procedure/package determines which company data the user has access/rights to.
With this, you should be able to achieve what you want if you do not want to spend on VPD and FGAC. The problem comes where there are users who would have cross access to data from both companies. In this regard, then you have to modify your security table a little bit to handle this.
B. This option i will admit is not so clean. You can also achieve this by two different views for every table in the application schema. And on each of these views, create a private synonym for every user. For illustration purposes:
Table name = Employee.
Create a view employee_a on employee
create a view employee_b on employee
Let's say you have users x and y. X has access to employees of company a and y has access to employees of company b. You can now create private synonyms for each of these users as follows:
create synonym employee on employee_a in x schema.
create synonym employee on employee_b on y schema.
This i have not tried but believe should work.
Hope one of these options serve your purpose.

How to implement row-level security in Discoverer?

Dear all,
I have a scenario that I have 2 folders containing sales and inventory data stored by product lines.
The 2 folders are constructed by 2 SQL statements.
There exists a set of tables controlling which product line's sales and inventory data a person can read.
A function is written previously that returns the WHERE clause based on user_id, employee_id and the other parameter.
So, can you suggest how to integrate the 2 components in Discoverer?
thanks
George
My blog: http://hktour.blogspot.com

hi Rod,
Thanks for your suggestions.
I took your 1st option, ie.
"You can use VPD at the database level to secure the tables."
I have a view BUDGET_V with the following columns:
PERIOD_YEAR
PERIOD_MONTH
PRODUCT_LINE
BUDGET_AMOUNT
Every salesman can only read the budget amount of certain product lines.
I built the security function which will be binded to the view BUDGET_V (see below)
FUNCTION security_policy_function( p_schema in varchar2, p_object in varchar2)
return varchar2
as
begin
if (user = p_schema) then
return '';
else
return viewProductLine(FND_GLOBAL.USER_ID, FND_GLOBAL.EMPLOYEE_ID, 'BUDGET_V.PRODUCT_LINE');
end if;
end;
The security function actually calls my own security function viewProductLine(FND_GLOBAL.USER_ID, FND_GLOBAL.EMPLOYEE_ID, 'BUDGET_V.PRODUCT_LINE') which take the user id and employee id of the apps user and returns the predicate.
Then, I bind the security function security_policy_function() to the view BUDGET_V with
begin
dbms_rls.add_policy
object_schema => 'APPS',
object_name => 'BUDGET_V',
policy_name => 'MY_POLICY',
function_schema => 'APPS',
policy_function => 'security_policy_function',
statement_types => 'select',
update_check => FALSE,
enable => TRUE
end;
The problem now is that if I query the view in Discoverer as a Apps user (say "A"), it returns all the records in the view without any filtering (user "A" is supposed be able to read certain product lines).
I try to verify whether the security function work or not. So, I hardcoded FND_GLOBAL.USER_ID and FND_GLOBAL.EMPLOYEE_ID as 1234 and 6789 which are the user_id and employee_id of user "A". (see below)
FUNCTION security_policy_function( p_schema in varchar2, p_object in varchar2)
return varchar2
as
begin
if (user = p_schema) then
return '';
else
return viewProductLine(1234, 6789, 'BUDGET_V.PRODUCT_LINE');
end if;
end;
This time, Discoverer returns only the records with product lines visible to user "A".
So, I guess there is problem in the function call in viewProductLine(FND_GLOBAL.USER_ID, FND_GLOBAL.EMPLOYEE_ID, 'BUDGET_V.PRODUCT_LINE');
Can you give me some light on this issue?
thanks

How to implement data level security

How to implement data level security in BI Publihser?. I am using Obiee enterprise edition and bi publihser. My requirement is to show data based on User- Region relation ship.
User A - belongs to Eastern Region
User B - belongs to Southern Region
so if user A logged in he should see only Eastern Region report. If user B logged in He should see only Southern region. I am using direct sql to my oralce database as data source.
i appriciate your help

I am using a common database username and password for jdbc connection. what i am looking is based the BI Publihser login, is there any way?
say i have userregion table joined with fact. so that i can write a query to get the data
select c1,c2,c3
from userregion, fact
where fact.region=userregion.region
and userregion.user = BIPUBLIHSERUSER
but my question is ithere any variable to tell who is logged in BI Publisher? Any server varaibles?
Other related question is, In every report i want to show User name who is running the report. How can i get this?

Tips on Implementing Row Level Security

Dear All,I am currently trying to implement row level security in Hyperion Intelligent version 8.2. The user guide is straight forward on explaining the steps. However, when I tried it, the row level security does not filter the information at all eventhough I have set the row level security setting in System Administration. Is there Anyone who can share their problems and experience when implementing row level security in Hyperion Intelligent version 8?Regards,Ricky

I don't believe you need the bqy file anymore, as you set up the ODBC to connect to the database of the EPM Workspace since it contains the 3 tables (BRIOSECG, BRIOSECP, BRIOSECR).
(I don't have an EPM instance with IR installed to check currently).
Note: from the docs quoted earlier:
If you want to implement row-level security in Reporting and Analysis, keep these points in mind:
At least one Hyperion Interactive Reporting Data Access Service instance must be configured to access the data source storing your row-level security information.
The database client library should be installed on the computer where the Hyperion Interactive Reporting Data Access Service is running.
The data source for the Reporting and Analysis repository that has the row-level security table information should be configured.
For security reasons, the user name and password to access the data source should differ from that used for the Reporting and Analysis user account.

SAP Lumira - Implementing row level security

Hi All,
I aware that SAP Lumira 1.17 onward allows to share the datasets, stories to SAP Lumira Server as well as SAP BI Platform (4.1 SP3 onward).
But I would like to know if there is any way of implementing Row level security for this published contents i.e. datasets or stories. e.g. If user A (may be an administrator with access to all the regions) creates dataset and story and shares it with other users over SAP Lumira Server or SAP BI Platform. But when user B accesses these contents on any platform, SAP Lumira server or SAP BI Platform, he should be able to see data only as per his access (his own region). Can something of this sort be implemented?
Thanks,
Abhijit

Hi,
Sorry for the delay in getting back to you.
As per my understanding - as of today, we respect Row-level security when acquiring (fetching) the data from universe into Lumira desktop (also, contexts and business-security profiles i.e. columns)
now, when that desktop user has 'designed' the Lumira document, all of the above: row-level, contexts and security profiles are 'locked-down' into that artefact when shared onwards. (i.e. to Lum Server and hence, BI Platform)
once this content is being access from the BI Launchpad, refresh-on-demand is possible from the story, as well as scheduling of dataset on which it is based.
According this blog by Greg Wcislo (the product owner for the Add-on) Lumira integration for BI4 functionality detailed. note that features such as 'refresh on open' and 'changing design-time parameters' (i.e. prompts) are not yet supported, but very much in future scope / plans.
I believe that one of the other mid-term goals is to architect a 'Lumira server-side universe refresh' (i.e. so that the processing is handled 100% by Lumira server) rather than querying across BIPlatform services then replicating a dataset to HANA (which is currently the process flow)
I hope this helps.
Regards,
H

Row Level Security using BO SDK - Dynamic Group and Criteria (where clauses)

To the Universe Gurus out there:
I have a rather daunting task of implementing a Row Level Security on a number of tables within our project using BO XI R2 SP2 with SQLServer 2005. Given the nature of the requirements around this (listed below), I am going to go with BO SDK to accomplish the creation of Restrictions. That said, I need some insight into some of the problem areas I have listed below. Any help is much appreciated.
Background:
We have 11 tables that are to be restricted.
Each table is accessible to potentially 1..* group of users only.
For eg SALES is accessible to ALL_SALES members only.
Each row within each table is accessible to 1..* groups of users only. The restriction will occur on 2 columns Jurisdiction and LineID on SALES table.
For eg
1)Rows with NY Jurisdiction and LineID=123 are accessible to NY_SALES_ADMIN group only initially.
2)NY_ADMIN will then approve that the above rows be open to NY_SALES_INTERNAL group only. This approval in turn will call upon the BO SDK to add a new restriction for the group with appropriate where clause.
3)At a later point, the above rows will be opened to NY_SALES_EXTERNAL group also.
This same concept holds good a number of jurisdiction (more or less static) and a dynamic number of LineIDs. So, if 10000 rows of data corresponding to new LineID 999 and Jurisdiction AK are in the table now, they are initially accessible only to AK_SALES_ADMIN group only. No one else should be able to access it.
Results:
1) With the way I laid out the business rules above, I am ending up with 528 groups.
2) There is a restriction created for a unique combination of Jurisdiction and LineID for each table.
Problems/Questions:
How can I restrict access to the new rows to one group only. I know that I can let a certain group only look at certain data but how can I restrict that all others cannot look at the same.
AK_SALES_ADMIN can look at LineID=999 and Jurisdiction='AK'.
Do I use an Everyone group based restriction? If so, my Everyone group will end up with tons of restrictions. How will they be resolved in terms of priority.
Am I even thinking of this the right way or is there a more noble way to do this?
Regards

the connectinit setting should look something like this:
declare a date; begin vpd_setup('@VARIABLE('BOUSER')'); Commit; end;
The vpd_setup procedure (in Oracle) should look like this:
CREATE OR REPLACE procedure vpd_setup (p_user varchar)IS
BEGIN
DBMS_SESSION.set_vpd( 'SESSION_VALUES', 'USERID', p_user );
END vpd_setup;
Then you can retrieve the value of the context variable in your vpd functions
and set the vpd.

How to implement Dimension Level Security on Tabular?

Not possible on SQL Server 2014 SSAS Tabular? How to work around?
Kenny_I

Hi Kenny_l,
According to your description, you want to implement dimension security in SSAS 2014 tabular. Right?
In Analysis Services Tabular mode, dimension level security (based on role permission) is not supported. This security can only used in Multi-dimension mode. In tabular mode, we can only use row-level security based on role permission.
Please refer to links below:
Implement Dynamic Security by Using Row Filters

Comparing Tabular and Multidimensional Solutions (SSAS)
If you have any question, please feel free to ask.

Help with implementing Row Level Security in Interactive Reporting

We're deploying Hyperion BI+ 9.3.1, using Workspace and Interactive Reporting. I'm researching how we can use the Workspace row level security option. I've read what's available for documentation in the Workspace Administrator Guide and the Interactive Reporting Users Guide. I understand the concept of setting up rules with row_level_security.bqy, but I'm confused about where these tables should go and what actually happens when I go to Workspace > Administrator > Row Level Security and turn it on.
The Administrator's Guide tells me the "properties" are stored in the repository, but the "rules" are in the "data source". Does that mean my BRIOSEC* tables go in the database I'm running my reports from? If so, then what's the data source I'm filling in on Workspace > Administrator > Row Level Security?
I have many different database connections going to different Oracle and SQL*Plus instances, and I don't want to apply row level security to all of them. How does Workspace tell the difference between them? If I enable rules but create a report from a database that doesn't have rules defined for it, what happens?

The 3 tables used with the RLS are stored in the same schema as your repository by default.
The RLS store all the Rules for any database that you are using.
You define the rules based on the tablename (owner.tablename) and the column name.

What if I implement data level security using Selection formula?

Hi All,
I have a requirement to implement data level security for all the reports, the thing is, we donot have a front end application developed in java/.net or any other language, so we have only two options (as per me, if you think there are other alternatives then please share).
1) Implement security at the database level (that is use user roles in where clause which will make the where clause really complicated and hence the performance of the query will eventually decrease).
2) Retrieve the data with the flags of user role/permission on data. Use these flags in selection formula to select the needed records as per the user login.
I have already in middle of implementing the second method, thought to take suggestion from you guys, I appreciate if you could tell me the drawbacks of the method I am using, and if there is an alternative method you could think of.
Thanks,
-Azhar

Standaone Crystal Reports does not have any security option except to use Trusted Authentication when connecting to the DB. We use Microsofts NT or MS SQL Server Authentication only.
Doing this in CR Designer using flags and formula will never be secure, the user could simply change the formula etc...
Check with your DBA on how to configure AD authentication and then enable or add each user to SQL server. You may need to configure and mantain this manually depending on how you ahve your network configured.
Thank you

How to apply row level security against the database administrator

I would like an advice in applying row level security against the database administrator. We need to prevent DBA from editing data in some table rows or have any indication that data was corrupted.
There is no problem in viewing the data so we considered one way hash function or digital signature which will be stored in the same table, but we see following disadvantages:
HASH - DBA may use the same hash function to update the stored data after he changes the sensitive row.
Digital signature - the is a need to manage and keep the private key in a safe place outside of DB
Is there additional ways to achieve the aim?

Does VPD helps to prevent from DBA to edit/view a data in specific rows?Yes.
If I correctly understand, DBA has full access to security policy used by VPD to control the access and can grant himself privileges that I don't want.You can to define which users can be exempt of the politics, for the context or by Grant EXEMPT.
This includes DBAs.
The simple fact of being DBA doesn't guarantee the exemption.
Everything goes to depend of the VPD config.
