Restricting Permission To A Column
Mar 29, 2007
I have a table with UpdateDate field and I want this field to be populated when a new record is inserted or an existing record is updated using the getdate().
But I dont want the users who insert or update records in this table to have control over this field. Meaning the users should not be able to populate or update this field.
At the same time when the user inserts or updates a record this field should be populated automatically.
Can this be done. Please let me know.
Thanks

Just encountered something that I wasn't expected, in that a user who has an explicit deny on a column in a table was able to select it when referenced through a view in a schema they have the SELECT permission on. This seems to me to go against the principle that DENY overrides everything when it comes to permissions? Is this how it's meant to work?
Code is below:-
--create test user
CREATE USER TestDenyOnViewUser WITHOUT LOGIN
GO
--create test schema (authorization dbo - same owner as dbo schema so ownership chaining will apply)
CREATE SCHEMA TestDenyOnView AUTHORIZATION dbo
[Code] ......

I have an application that uses Integrated Windows authentication. My Web.config looks like below
<add key="dbconnection" value=" server=XXX;Initial Catalog=XXX;persist security info=False;Integrated Security=SSPI;Pooling=true" />
When users try to access my application, they get the below error:
Execute permission denied on object 'SprocName', database 'DBNAME',Owner,'dbo'
The Only way I could get rid off the error is if I set DBO permissions for the user group on the databse.
Can someone suggest how to set up a security group with the ‘necessary’ permissions on SQL SERVER (ie read,write execute Sproc etc) and not too many extra ones, like DBO.
Thanks,

First some explaination then the question. I have some users that legally or otherwise have gotten copies of SQL 2000 and installed it on thier local PC's. They are now using Enterprise Manager to connect to my database servers via IP and server name. They are using thier regular user id and passwords that they would use to log into the HR and Finance applications. For obvious reasons this is not a good thing. Now the question, can I some how restrict connections via EM to just thoses with an sa role? Or am I doing something else wrong or missed some hidden configuration.
Thanks in advance!

SQL Server 2005 anomoly?
In SQL Server Management Studio I granted specific permissions to user "A" to do Select, Insert, Update, Delete on Table "B" -
When I logged on as User "A" and attempted the Insert imto table "B" I got the following error:
"Insert Permission Denied on Table B, Database C, Schema dbo"
Is this a problem with the dbo schema?
Then I went back and created a stored proccedure "D" with the exact same Insert statement inside the procedure. I granted User "A" execute permission on the stored procedure "D".
I then logged on as User A and executed Stored Procedure "D". No Problem - stored procedure executed fine with the Insert.
I attempted the Insert statement again - straight SQL - as User "A" and got the same error as above ("Insert Permission Denied.....")
Strange behavior - cannot do a SQL. Insert even though user has permissions but can execute a store procedure with the same Insert statement.
What gives?

Hi all
Certain people in our company want to use Crystal Reports for data-processing. Problem is we want them to NOT be able to access data in databases within the live server.
Given that we use trusted connection to validate all kind of data-access, I am wondering if there is a way so that (via NT administration or via some SQL Server security features)
the live-server can refuse any connection request from the Crystal Reports application. At the moment the same group of people are allowed access to database (and should remain to be so) on this "live" server via some other applications (e.g. Microsoft Access).
Any advice is welcomed.
Simon

I have users logging into a sql database using sql accounts. I've created below a simplified example of three tables in my 100+ table database. I have a sql table that holds extra information about the sql users and two data tables. I would like to restrict which records the user has access to in the manufacturer and automobile tables. I know I can add the UserID column to these two tables, and then add the appropriate userID into the UserID column of the manufacturer and automobile tables. Hence records in the automobile table with userid X will not be seen by userid Y. My question is, how can I possibly avoid modifying 1000+ sql queries to reference the UserID column? It would save me a lot of time if I can filter the results a user gets based on thier sql login/userid.
+--------------------------+
+ USERS TABLE
+
+ USERID int
+ Name varchar
+ Telephone varchar
+
+--------------------------+
+--------------------------+
+ MANUFACTURER TABLE
+
+ MANID int
+ Name varchar
+
+--------------------------+
+--------------------------+
+ AUTOMOBILE TABLE
+
+ AUTOID int
+ Name varchar
+

I'm going through the SQLSecurity Checklist I found at sqlsecurity.com. One of the points it says to "Restrict to sysadmins-only access to stored procedures and extended stored procedures that you believe could pose a threat." It also lists a bunch of stored procs and extended stored procs that you should consider restricting to sysadmins only. I was wondering if someone could give me some pointers on how to do this? I would like to write a script that I could run on every sql server 2000 install that would do this. How could I ensure that every user does not have access except the sysadmins?
Thanks,
Chris

Would like to restrict the dates users can put as parameters. For example, I have a report showing all orders in year 2007. I have exposed Start Date and End Date parameters. When users click the 'View Report' button, the report will filter for orders where attribute EnteredDate is >= Start Date and <= End Date.
I want to restrict the users from entering a start date greater than today's date. Would also like to restrict them from entering an end date that is less than the start date parameter. How can I do this?
TIA.

Hi
We are developing some applications for Sunit computers (In-vehicle computers) which have limited memory . Because the applications display maps, the will consume alot of memory. Because of this, we want to restrict the amount of memory and other resources SQL Server Express uses to a minimum. I've tried setting 'max server memory', which doesn't help too much as this is only a limit on the SQL engine and not the sqlserver.exe process. What other settings and restrictions can I apply to limit memory consumption by the process?
We have considered using SQL Server Everywhere, but as it doesn't support ODBC (will there be any ODBC support?), we are not too happy about using it. As of now, we have no experience with OLE DB, and the application is MFC 6.0 so we can't take advantage of ADO.NET
Best regards

Hello everyone,
I have a design problem which I am hoping somebody can shed some light on.
I am running SQL Server 2000 using SQL authenticaiton (due to be changed to Windows authentication in the next 6 months). I have a table in my database which we shall call monthly. I want to restrict the ability to insert to the monthly table to 2 stored procedures (proc_abc & proc_xy) which I have written which do various other validation checks before it inserts the data into monthly.
Users with the Foo function assigned are able to execute proc_abc & proc_xy
I have written a VB application which can be used by users who are not familiar with SQL to be able to execute these stored procedures. (Must have Foo function in order to login to this application).
I want to restrict the ability to execute the stored procedures to users using the VB application only, and thus not be able to execute the stored procedure using Query Analyzer or such like for any Foo user.
Is there anyway I can do this?
One suggestion put to me is two split the functions. Have one function lets call it Top which can access the VB application and then have another function called Bottom which is able to execute the stored procedures. Only the VB app would have access to the Bottom credentials. But is this secure? Would I just hard code the credentials for the Bottom function user within the VB app? This doesn's seem a secure way of doing things to me.
Thanks for the help!

Is there any way to restrict the user from selecting the parameters. For example: I have a list of 100 values in a multi-value parameter. I want to to restrict the user to select at the most N number of values.
If possible, process only the N number of values will also do.
Thnx in advance...

I want to provide access to one of my users to a database on the production server. I do not want this user to be able to view anything other than the tables in that database, or the other databases on my production server.
I gave him access to one DB - TestDB- and made him data_reader on that DB. I had set that as his default database. However, when he logs in using SSMS he can see from Object Explorer a listing of all the databases on that server, although he can't access any of those. This is an external user and I don't want him to see any of that stuff, including other objects (SPs, Views, etc.,) even within TestDB.
To summarize, I want to grant access to a windows user to see/select from ONLY tables in TestDB of my production server, and I do not want him to be able to see any objects other than tables of this DB from SSMS.

Hi
I'm building a data warehouse - my end users connect using Access via ODBC Microsoft SQL Server driver (2000.85.1117.00).
However, whenever they connect using Access via ODBC they get a huge list of sys and INFORMATION_SCHEMA views, in addition to the data warehouse tables they need to access.
How can I remove these sys and INFORMATION_SCHEMA views from the list of tables/views presented to the end user?
I've tried denying access by changing permissions to deny in the public role of the master database - I have also changed permissions in the public role in the data warehouse database. When I do this, the ODBC connection fails to retrieve any objects because it doesn't have access to sys.databases (and various other unspecified objects).
I'm stuck - help!

This is a slight re-stating from an older thread, which I think warrants some new discussion. The answer has always been that system administrators should have full access to everything on a system, including databases.
Although that is a logical position for internal IT departments it doesn't quite fit the model of systems with outsourced or external system support.
"If you don't trust your DBA, then you need a new DBA. They are in a position of authority for a reason and restricting that authority makes it impossible for them to do the job they are hired to do."
What about scenarios where you have local machine administrators that should NOT be given access to private data in a secured database, even though they need to be able to access and maintain everything else? And unfortunately some regulations are written about access to stored data whether encrypted or not...
In the modern world of Sarbanes-Oxley and PCI-DSS/CISP it is no longer so cut and dried. Especially where companies have software/hardware support contracts with third parties that require administrative access to other aspects of the systems.
So accepting that you might need someone to have administrative level access to the box but they should not be able to view the contents of a database installed on that box, what would you do?
Is there a way to create an adminstrative group that does not allow access to a specific named instance of SQL?
Is there a way to revoke access for one member of the administrators group only?
Thanks,
Ted

As a part of our infosec lockdown activity, we are giving a shared ID to all DBAs and would mandate them them to use that ID only. We have a tool from where they will do this activity.The situation what I am getting in with this is, what if they add give their own Active directory ID Sysadmin privileges or create a instance level Sysadmin to bypass our process.
