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.

Row-level security at the Database level

We need Row-level security at the Database level, where the user who logs in to Crystal reports, should be able to fetch only those rows from the database that he is entitled to see. For this, the login name of the user is passed to a stored procedure which sets the context of the DB session and restricts the data retrieved.
We are not looking for row-level security where the data is first retrieved and then filtered based on the user login name. However, we are definitely looking for a way to set a context for a database session based on the user login name, even before we start fetching data. So effectively, the user who logs in will fetch only those rows which he is supposed to see.
Issue:
We face a problem of not being able to pass a variable (something like 'BOUSER' for BO which works, whereas, 'CurrentCEUserName' for Crystal Reports, which doesn't work), to the database stored procedure to set the context.
Please let us know if we can use 'CurrentCEUserName' variable in Crystal in the same way as 'BOUSER' is used in ConnectInit for BO? We would like to know how we could pass any variable in Crystal Reports which holds the user login information to a stored procedure.
Also, please suggest alternate ways to achieve this security restriction, if any.

Hi
A previous database had a personnel table with their station name, district and region, with a field holding their logon name. We also had an activity table with the fields referring to the activity, and a field of Station, district and region it occured in.
By linking the individual rows in an activity table to the personnel table on the station name field, we then used the CurrentCEUserName to filter on the personnel. This returned only the records in the activity table where the station the activity took place at was the same as the station associated with the selected personnel who has logged on.
The additional bonus was if we linked it on District or region we had the same result but at a greater level. ie all activity in the logged on personell's District or if linked on region, then their region.
The personnel table was maintained by the system administrators, so maintenance was low.
I hope this helps.

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 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

How to enforce row level security on MSAS Cube

We have to enforce row level security on MSAS Cube based on BOUSER.
We are using a security table which contains BOUSER ID and Location ID
We need help in joining the security table with MSAS Cube.
Thanks

HI,
I haven't worked with cubes. But the will the knowledge I have in Universe, could probably help you.
As you already have a table which maintains BOUSERID and location id, you could probably join location id with MSAS cube id.
If you don't want to use this userdefined security table, you can use the inbuilt Row level security option.
Go to Tools -> Manage access REstrcitions --> Create a new restriction --> Rows tabe ---> give a expression with BOUSER
Hope this helps.

Applying row-level security to crystal report instance

Hi
we have created crystal reports based on sap r/3 data using open sql driver and imposed row level security and published to BOE.The user when opens report with view on demand can see the data which he is supposed to see.
Is it possible to schedule a single instance of the crystal report and then all the users access the instance and see the data that they are supposed to see.If not what is the other way out.
Thanks in advance.

Column masking row level security in Peoplesoft Databases

Hi
How about the credibility of using VPD( for column masking,row level security) in People soft Databases?where the sensitive data is redundant across 100's of tables.
My intention is to use the VPD across all the tables that contain the sensitive data ( ssn,bank accno, etc)
Appreciate your help.
Chelli

Hi.
I also have a trouble like yours,but mine is more simple.
I'd tried to solve,and find that it's really hard and must lost a lot of time to solve,because some table have 2,3 or more derive information that to use VPD is not easy.
Can i ask for any aspect to solve problem like this.
Thanks for any answer and support.

How to apply Table level Break in the WEBi Report

Hi,
How we can apply the table level break in the WebI Report.
I know a bit bt i dont know its right or wrong.. Initally we normally create a table(with the values(which has 2rows(1: for naming and 2: for associating the object with it at down of it ie., one above and one below)) and at the top of that present table we will insert a "ROW ABOVE" to the naming row and then we insert a "Row below" to the object values and drag the first coloumn of the first row almost invisible(naming row) and then the same in next row(objects associating values for naming)... is this ryt.. if NO thn let meknow the various ways to do it..
Thank you in Advance....

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

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 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.....

Row level security not working if I hit the aggregate

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..
