Suggestion required for using row level security

We have a scenario to provide row level security to some of the transaction tables like HR_EMPLOYEE which has a foreign key column DEPT_ID to HR_DEPARTMENTS table. This table may grow up to about 5 million records. There could be regular SELECT operations on this table and not so frequent UPDATES compared to the SELECT operation.
We were looking at the following approaches...
Table :
HR_EMPLOYEE
     EMPNO
     DEPT_ID
     LAST_NAME
     FIRST_NAME
1. Enable Oracle Label Security policy on this table and use static predicates.
In this approach we add the OLS policy column (POLICY_COLUMN) and add predicate to access data.
e.g. we will be giving access to global data by predicate like
OR POLICY_COLUMN =CHAR_TO_LABEL('POLICY_NAME','C::DEPT1')
where C::DEPT is the OLS Label
2. Using VPD policy. We donot add any column, instead use the existing column DEPT_ID to provide row label security. In this approach the DEPT_ID is to be compared against an additional table and DOMINATES function will be used to verify the permission for the user to access the data.
e.g. In this approach, the policy function is like
'DOMINATES(char_to_label(''POLICY_NAME'', SA_SESSION.LABEL(''POLICY_NAME''))
,char_to_label(''POLICY_NAME'', POLICY_PKG.GET_LABEL_FROM_DEPTID(DEPT_ID))) = 1'
The GET_LABEL_FROM_DEPTID function returns the OLS label for the corresponding department. This is compared with the user's session label and appropriate rows are given access.
Can someone suggest on which of the above approaches is more performance effective considering the number of records and the additional OLS column added to the table.

Hi there,
would you be able to describe as detailed as possible what you want to achieve? From my first glimpse at your code, it seems as if you are using both OLS and VPD in a rather extraordinary way.
Best, Peter

Row Level Security not working for SAP R/3

Hi Guys
We have an environment where the details are as mentioned below:
1. Crystal Reports are created using Open SQL driver to extract data from SAP R/3 using the SAP Integration Kit.
2. The SAP roles are imported in Business Objects CMC.
3. Crystal Reports are published on the Enterprise as well.
3. Authorization objects are created in SAP R/3 and added as required for the row level security as mentioned in the SAP Installation guide as well. The aim is when the user logs into the Infoview and refreshes the report he should only see data that he is meant to so through the authorization objects.The data security works very much fine when the reports are designed directly on the table but when the reports are built on the Business View it doesnt work hence the user is able to see all data.
Any help in this issue is greatly appreciated.
Thanks and Regards
Kamal

Hi,
In order for row level security to work for you using the OpenSql driver, you need to configure the Security Definition Editor on your SAP server. This is a server side tool which the Integration solution for SAP offers as a transport.
This tool defined which tables are to be restricted based on authorizations.
However since you are seeing the issue on reports based on Business Views, you need to identify whether the Business View is configured in such a way where the user refreshing the report is based on the user logging into Infoview. If the connection to your SAP server is always established with the same user when BV is used then you security definition is pointless.
You can confirm this by tracing your SAP server to identify what user is being used to logon to SAP to refresh the reports.
thanks

Report based row level security

I have a requirement to have row level security on only one particular report - so a user in the "Accounting" group - when running this report can only see the "Accounting" business unit but not any of the other business units such as "food service" or "training" - however when running any of the other reports - they are able to see all business units. Is there a way to deploy row level security so when a particular report is run that the security filter is applied - and not in all cases?
thanks very much for your help!

Kapsnerc,
One way to solve your problem is to duplicate the column in your rpd and then define security accordingly.
For this report use the duplicated column and for the rest use the original column to build the report.
Regards,
Venkata.

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.

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.

Row level Security for BI Author Role

Hi All,
We are using OBIEE 11.1.1.5 in our project. We have a requirement where we need to configure row level security on certain column.
We are currently using external table and session variable approach to configure this. This security works fine for the users with BI Consumer
roles. But we are facing issue with configuring row level security for BI Author role.
BI Author can create any analysis in BI Answers and suppose he/she creates a report which does not contain the column on which row level
security is applied than he can see all the data. For eg.
We have one dimension Products having two levels Product Division and Brand. I want to configure security based on Product Division column.
But if BI Author create a report with only Brand and Measures than row level security is not working.
Does anyone has face this issue before.
Please let me know if you want any other information from my side.
Regards,
Vikas

If you are using a multidimensional cube you can use the "permit" command to control access to dimension members or provide cell level security within the cube. The OLAP database documentation provides on how to use the PERMIT command.
If you are using relational tables and/or views with additional CWM metadata mapped using OEM then you need to refer to the database documentation relating to Virtual Private Databases and Label Security

Row-level security problem using VPD

Hi all,
I've implemented row-level security for my application using the following procedure:
1) Created a procedure for setting the context for the application:
PROCEDURE set_empno
IS
emp_id NUMBER;
BEGIN
BEGIN
SELECT empno
INTO emp_id
FROM SCOTT.EMP
WHERE upper(ename) = SYS_CONTEXT('USERENV', 'SESSION_USER');
DBMS_SESSION.SET_CONTEXT('emp_sel_context', 'empno', emp_id);
EXCEPTION
WHEN OTHERS THEN emp_id := 0;
END;
END;
2) Created the application context:
CREATE CONTEXT emp_sel_context USING secman.app_security_context;
In which secman is my security schema and app_security_context is the name of above procedure package.
3) Created a function to access the application context:
FUNCTION emp_sec(E1 VARCHAR2, E2 VARCHAR2) RETURN VARCHAR2
IS
e_predicate VARCHAR2(2000);
BEGIN
e_predicate := 'empno = SYS_CONTEXT(''emp_sel_context'', ''empno'')';
RETURN e_predicate;
END;
END;
4) Created a logon trigger:
CREATE OR REPLACE
TRIGGER INIT_CONTEXT AFTER
LOGON ON DATABASE
BEGIN
SECMAN.APP_SECURITY_CONTEXT.SET_EMPNO;
END;
5) Added a policy on scott.emp like this:
begin
dbms_rls.add_policy (
object_schema => 'SCOTT',
object_name => 'EMP',
policy_name => 'EMP_SEL_POLICY',
function_schema => 'SECMAN',
policy_function => 'EMP_SECURITY.EMP_SEC',
statement_types => 'SELECT',
update_check => TRUE
end;
My problem is that when a user queries the EMP table the above procedure does not work and 'no rows selected' is returned for each user that queries the table. Does anybody know which part of my procedure is wrong?
Any helps is really appreciated.
S/\EE|)

i,
I suggest:
create another table emp1(logon with scott),this table only include empno,ename,then insert a few record,then modify
procedure set_empno as
PROCEDURE set_empno
IS
emp_id NUMBER;
BEGIN
BEGIN
SELECT empno
INTO emp_id
FROM SCOTT.EMP1
WHERE upper(ename) = SYS_CONTEXT('USERENV', 'SESSION_USER');
DBMS_SESSION.SET_CONTEXT('emp_sel_context', 'empno', emp_id);
EXCEPTION
WHEN OTHERS THEN emp_id := 0;
END;
END;
certainly ,you should grant select on emp1 to the user who will be test.

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.

Row level security without using VPD

I am wondering if there is a way to have row level security in APEX without having to use the virtual private database (VPD). I cannot afford the Enterprise Edition license that is required for VPD.
I need a way to customize the list of rows that appear for each user on a report page.
For example, I only want managers to be able to see their employees and not employees of other managers.
Thanks for your help !
-Reid

While it wont provide all the features that Oracle RLS does, you can leverage Oracle 'Contexts' to provide a form of Row Level Security.
This article describes how
http://www.dbazine.com/oracle/or-articles/jlewis15
Within APEX you can set your application to call the 'context' setting function in the 'VPD' section of the 'Edit Security Attributes' page.

Dynamically creating policies for Row-level security (RLS)

Hi everybody,
I’m looking for suggestions on how to configure Row-level security (RLS).
I have a large number of tables (about 500) and about 100 database users. Each user must see a portion of the data, filtered on a specific field. The field used to filter the data is a Client Id (let’s assume for simplicity that this field is present in all tables and has the same name everywhere).
Some users must be able to see just one client, other users must be able to see a group of clients, and some other users must be able to see all the clients. The association between Users and Client Id’s is stored in separate database tables.
I’d like to avoid having to manually create a policy for each table, so I’m looking for a solution that makes use of pl/sql programs to create policies dynamically.
Has anybody already implemented anything similar? Can you share your approach? Of course I’m looking for the easiest / most robust / most flexible way to implement this.
Andrea

It sounds like you would want a single policy function and that you would then apply that policy function to all 500 tables (at least given the simplifying assumptions you make in your question). If your policy function simply returned the `WHERE` clause
client_id IN (
    SELECT client_id
      FROM table_mapping_user_to_client
     WHERE user_id = <<something that identifies the current user>> )Then you would simply apply that policy to all the tables
FOR x IN (SELECT * FROM dba_tables WHERE <<condition to find the 500 tables>>)
LOOP
dbms_rls.add_policy(
    x.owner,
    x.table_name,
    'Restrict by client_id', -- name of policy
    <<owner of function above>>,
    <<name of function above>> );
END LOOP;Justin

Row Level Security Not working for the ECC table.

Hi All,
We have created a crystal report using SQL Driver.
We have set the row level security on PA0001 table so that we can restrict the query based on Company Code.
But when I run the report, it bypasses the row level security and gives access.
Am I missing some configuration?

Hi Ingo,
Security is set up using /crystal/rls transaction. A custom auth object is used for checking the company code with a single field "BUKRS".
This custom auth object is maintained for the PA0001 table.
This object is added at the role level with the restricted access to the Company Code..

Row Level Security in OBIEE using OID as authentication Mechanism

Hi OBIEE Gurus,
I am trying to implement Row Level Security in OBIEE . Currently I have setup OBIEE to have OID do the user authentication.
I want to implement RLS by doing the following :
1. Have Security Groups defined in OID and assign users with group membership.
2. Import these Security Groups into OBIEE metadata
3. Apply filters to these Security Groups
4. Run Answers requests to see if RLS works or not
Please let me know if this approach works. If this is not the right way or most efficient way to do this, please let me know if there is any document I can follow to accomplish this.
Appreciate your help.
Edited by: drakesh on Sep 26, 2008 7:09 AM

Follow the steps in the following link to set up OID and Row level security:
http://www.rittmanmead.com/2007/05/21/using-initialization-blocks-with-ldap-and-database-queries-to-control-authentication-and-authorization/
Instructions for the link above:
1.In place of Edit Data Source as database you have to select LDAP,define the groups and default initializer as filter expression.
2.A more simpler approach ,is to create the groups explicitely using the Security Manager in BI Administrator, add filters to those groups, and assign users to those groups.
Otherwise follow Matt's view

How to check the row level security in TOAD for oracle

Hi ,
for ex, i have 2 types of users
normal user and super user
super user can see the group set (some column name) created by normal user
but normal user can not see the set created by super user
this set crestion aslso has 3 types "U','P',S'
P & S can be viewed by even normal user
but U should not
so here we are having some row level security for the normal user .....
So, in TOAD for oracle how to check that......
Let me know if i'm not clear

Like
I'm the super user....
And some records are inserted to a table by different users ('a' , 'b', etc....)
So,if user 'a' logins then he can be able to see only the records inserted by 'a' only...
how to see in TOAD where such type of scripts (filter conditions) are written.....

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
