HOW CAN I PROTECT SQL DB IN AN EXISTING SERVER?
Mar 14, 2008
Dear Colleagues,
I have designed a Microsoft SQL Server 2005 database application using Visual Basic 2005. I want to control access to the database programmatically, without the End-User opening the database in SQL Server.
I want to protect the database structure such as my tables, code, etc. This restriction should include all the Administrators of the Computers on which my application will be deployed. Any modification of my database or code should be implemented only by me.
What is the best way to do this using (a) Windows Authentication Login? (b) SQL Server Login? How do I configure the User-Login?
NEW: In addition to above question, how best do I achieve this protection if installing the DB with other databases in an already existing server, is it possible to remove the Builtin Admin from the server role?? As in my case, there is no need for anyone else to open the DB in Management Studio at all as my VB application does all that is required.
Thanks and best regards,
Peter

I have a problem protecting a SQL 2005 SP2 server on Windows Server 2008 (64bit), running DPM 2007 on Windows Server 2003 (32 bit).
The following SQLVDI event ID 1 is logged in the event viewer:
SQLVDI: Loc=SVDS:pen. Desc=BADMEM. ErrorCode=(-1). Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=Global{CC60D260-C5DD-406A-9E63-64A9503A9763}1_SQLVDIMemoryName_0.
The UUID changes each time the event is logged, but the first event is followed by:
SQLVDI: Loc=SVDS::Cleanup. Desc=Close(channel). ErrorCode=(6)The handle is invalid.
. Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=Global{CC60D260-C5DD-406A-9E63-64A9503A9763}1_SQLVDIMemoryName_0.
Then this is repeated twice:
SQLVDI: Loc=SVDS::Cleanup. Desc=Close(channel). ErrorCode=(6)The handle is invalid.
. Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=.
Event ID 3201 is then logged by MSSQLSERVER:
Cannot open backup device '{CC60D260-C5DD-406A-9E63-64A9503A9763}1'. Operating system error 0x80770006(error not found).
This is followed by Event ID 3041:
BACKUP failed to complete the command BACKUP DATABASE CommunityServer. Check the backup application log for detailed messages.
It looks to me like the virtual device creation fails in the first step, the next three event messages are the cleanup of the failed virtual device, and the final two messages are the failed SQL backup as the expected device doesn't exist.
My question is why? The message seems to indicate bad memory, but I'm sure the physical memory is good - The 16GB in this server has been tested extensively, and I have no other issues. Perhaps its some sort of memory allocation error?
I'm going to apply cumulative update 7 to this SQL server to see if it makes a change. What's the latestest version of sqlvdi.dll available?
TIA,
Karl.

We have a commercial VB.NET winforms client/server application that utilizes SQL Server 2005 express edition. The schema and data that the application utilizes is proprietary and could be very damaging if it got into a competitors hands.
Is there any way to protect the data and schema of a sql server 2005 express edition database?
Will this functionality ever be added?
Thanks

My client maintains its HR data in an application that uses Oracle as its backend. This highly-sensitive data is basically off limits to all but a select few. Presently, I use a program in Access 97 that allows one high level HR person to pass their login to linked Oracle tables and copy a large chunk of this data to Access tables. From there I can morph it as needed for the Personnel, Safety, EEOC and other areas. The client sees this PW-protected, encrypted Access DB as safe because, being "only an Access DB", it falls below the radar of IS. This basically means IS can't get to the data. However, accessibility and scalability are non-existent. I'd like to reduce the Access DB to a shell that simply links to Oracle and SQL Server 7 tables and performs a straight pipe of the raw data between DBs. However, now IS will be very interested (since it's SQL 7) and have Admininstrator rights, therefore causing the HR people to squash the deal. How can I lock SQL 7 up so tight that IS can't get to the data and yet be able to maintain the DB? If this is not feasible, are there any other options that might provide a solution?

Hello.
I have a report with parameter called "parm1", that gets a value of "true" or "false" depanding on another parameter.
When the report is runnig the parm1 value is "false".
How can I protect this parameter from a change by the user?
I mean - the user can run the report and then add to the url "¶m1 = true".
Can I do anything against that?
I tried marking it as "internal" and I thought that now it can get his value only from inside the report but it didn't worked.
Any ideas?
Thanks.

Hi,
Just read about SQL injection, and tested it out with sample database, and it does hack my database, the article show to prevent SQL injection by using application code to remove those keywords and change single quote to double quote, is there any method to prevent SQL injection directly using the database system itself, maybe stored procedure or anything?
Thanks.

I have a DB on my SQL Server Express 2005. In this db I have one table and I DON'T want any user can modify data on this table but I want only show this data (only select statements allowed). If I install this db on one of my customers' machine, I can see that he can modify data into this table If he log in into the database with windows authentication and not with the "USERLOGIN" that I have created with sql server authentication. What can I to to remove dbo access in Windows authentication in my db and "transfer" the dbo in another user access (like MYUSER with Sql Server authentication)?
Thank You

Hi Everybody:
We have a table which needs to be updated 2 million times per day. It hosts all real time transaction. There are 200K records in this table. Would you please to share your experience with me about how to protect/save such table in SQL 2000 from any possible damage?
We plan to use point-in-time backup (every 5 minutes). It still takes at half an hour to recover the whole database. Any new technology from Microsoft or SQL 2000 you can recommend?
Thank you very much.

Hey!
This post contains the code for this thread: http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=14475
It deals with the problem how to prevent log actions in long running batch jobs from being rolled back. It was heavily inspired by Andy Pope´s approach to error handling (http://www.sqlteam.com/item.asp?ItemID=2290) and in fact you will see much of his code here.
The code:
This procedure dynamically opens a second connection in parallel to the existing connection of the calling procedure using SQL-DMO. So the second connection runs without the scope of transaction of the calling procedure. So no action you take here is rolled back in case the calling proc fails. So be careful! Keeping data integrity is your job here and you could do many weird things to your database.
The procedure dynamically adds a user function that if called just would return the object token of the new DMO connection. So any piece of code in the same batch could reuse the exisiting connection.
LogConstructor
CREATE PROCEDURE LogConstructor AS
if exists (select * from sysobjects where id = object_id (N'dbo.MFF_GetLogObject')
and OBJECTPROPERTY(id, N'IsScalarFunction') = 1)
drop function dbo.MFF_GetLogObject
DECLARE @Error INT
DECLARE @ErrorMsg VARCHAR(255)
DECLARE @oSQLServer INTEGER
DECLARE @Source VARCHAR(255)
DECLARE @Return INTEGER
declare @dynsql nvarchar(3000)
-- Create the SQLServer object
EXEC @Error = sp_OACreate 'SQLDMO.SQLServer', @oSQLServer OUT
IF @Error <> 0
GOTO OA_Error
-- Set the login process to use NT Authentication
EXEC @Error = sp_OASetProperty @oSQLServer, 'LoginSecure', -1
IF @Error <> 0
GOTO OA_Error
-- Connect to server using NT Authentication
EXEC @Error = sp_OAMethod @oSQLServer, 'Connect', NULL, @@SERVERNAME
IF @Error <> 0
GOTO OA_Error
-- Verify the connection
EXEC @Error = sp_OAMethod @oSQLServer, 'VerifyConnection', @Return OUTPUT
IF @Error <> 0
GOTO OA_Error
IF @Return = 0
GOTO OA_Error
-- Create Function with server object
select @dynsql = N'CREATE Function MFF_GetLogObject () RETURNS INT AS BEGIN RETURN ' + cast(@oSQLServer as varchar) + N' END'
EXEC sp_executesql @dynsql
return
OA_Error:
-- Get the error text
EXEC sp_OAGetErrorInfo @oSQLServer, @Source OUT, @ErrorMsg OUT
SELECT
@ErrorMsg = CONVERT(CHAR(16), @Error) + ': ' + @ErrorMsg + ' (Source: ' + @Source + ')'
print @ErrorMsg
return
GO
The next procedure just drops the DMO connection and also drops the user function as the token is invalid by now. This proc should be called within the same batch as the constructor to clean things up properly.
LogDestructor
CREATE PROCEDURE MFP_LogDestructor AS
declare @lo int
select @lo = dbo.MFF_GetLogObject()
exec sp_OADestroy @lo
if exists (select * from sysobjects where id = object_id(N'dbo.MFF_GetLogObject')
and OBJECTPROPERTY(id, N'IsScalarFunction') = 1)
drop function dbo.MFF_GetLogObject
GO

I got a problem concerning encryption. The thing is I have decided to use symmetric key protected by certificate to encrypt certain information. Certificates are protected by database masterkey and by service key.
But I also want to be sure that if someone steals my database with all its data he wont be able to decrypt it with his own SQL Server Management Studio where he has all the permissions.
Also after some time I will need to take my database and set it up on another PC.
Has anyone ideas how to solve this??
P.S. As far as I know if symmetric key is protected by certificate which is protected by DB master key and service master key then you cant decrypt data if database is moved to another workstation and opened with another Management Studio. Please can anyone explain how this works( if its true). And if this is true then how can i move my DB without loosing access to encrypted data???

I went to look at the connection string previously entered for a dataset created in a new report, and am not seeing anything intuitive for bringing up the associated datasource dialog box that was used to enter name, type and connection string. I'm also noticing nothing intuitive for deleting an existing dataset. How do you do these two very simple things in an existing project? I dont see the dataset in solution explorer, I see it only in the text box on the data tab and in a limited kind of way on the dataset view where the columns show and maint is allowed mostly on the columns only. I tried hilighting the dataset here and hitting the delete key to no avail.

Hi All,
I would like to restore database using RESTORE DATABASE ... REPLACE command.
If database exists already and has any open connections this command will fail.
I would like to close all existing connections to specific database before running RESTORE DATABASE ... REPLACE command.
I can do closing from Management Studio using checkbox "Close Existing Connection" when deleting database. Actually I need to do the same but from script.
Please advice me how to do it.
Thanks in advance,

I am exporting the data from database to an excel template that will have 100+ columns and approx 4000 rows of data. Then the business user will make changes to some columns without modifying primary key columns and will send back to us where we will update the same to database.
In order to this am using an excel template by protecting the primary key columns with a password protection.
At template level am fine and whenever am trying to modify any primary key column it's not allowing and am totally good there. But when I use that excel template as a destination to load data from SSIS, all the protected columns are no longer protected and i could able to make changes.

My web project (ASP.NET 2.0 / C#) runs against sql server 2000 and uses the System.Data.SqlClient.using System.Data.SqlClient;
I use System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlCommand to make the connections to the database and do selects and updates. Is it correct to continue to use these against SQL Server 2005? I ask because I made a connection string (outside of .Net) for SqlServer 2005 using the SQL native provider and it had the following - Provider=SQLNCLI.1 and any connection strings I had made (also outside of ASP.NET) fro SQL Server all used Provider=SQLOLEDB.1. This is why I wondered if there is a different SqlClient in .Net 2.0 for SQL Server 2005?
Cheers

Hello
I was using SQL SERVER 2000 ... In one table I've created FULL TEXT SEARCHING ( Full text catalog along with full text indexing)
Now we had to install our db in SQL SERVER 2005 standard edition. But while taking script it gave me two lines like:
if (select DATABASEPROPERTY(DB_NAME(), N'IsFullTextEnabled')) <> 1
exec sp_fulltext_database N'enable'
GO
if not exists (select * from dbo.sysfulltextcatalogs where name = N'DEV_CAS_DiagnosisCatalog')
exec sp_fulltext_catalog N'DEV_CAS_DiagnosisCatalog', N'create'
GO
so I used this in the new db creation script...
But I couldn't get where it actually is in SQL SERVER 2005 standard edition.
and also plz help how should we create if it doesn't exist...
What could be the problem....
Thanks In advance

Hello!
What is the best way to make a copy of an existing sql server database to another (physical) server?
Plan to make a full backup of another sql server database to another server. I've read about detach and attach
and copying the datafiles and log files but some say it is prone to data loss? Is this true?
And another thing, what if the existing sql server can't affor downtime for me to copy db files etc.?
Anybody here who have done the same?
Any help is very much appreciated.

Please can anybody help me in transferring existing SSIS Packages saved in a shared folder location from development server 2ED to Live server TWD1.
Both has SQL server 2005 running and has visual studio 2005
Currently about 25 SSIS packages are executed from the development server transferring data on Live server TWD1...these ETL process is called from development server but executed on live server.
Now the problem is when i call these packages from the shared folder from live server it crashes.....i need to changes something to shift the whole package to the live server..and execute on live server itself instead of recreating the whole 25 process from scratch.....also i use optimize for many tables ..and run in a single trancastion....so how can i see the mappings of source and destination tables.
Please let me know the process how i can achieve this.
Thanks

I have an urgent query that we are running SharePoint server 2013 on single server and installed SQL server 2012 on single server, our management decided that we need to configure failover cluster on existing SQL server. I want to confirm that it is possible that we can install failover clustering services on existing SQL server and then add an other server on SQL 2012 for high availability or do we need to first install failover cluster service and then install SQL server for failover clustering.

I have SQL 2000 server machine on our network.
I can connect to our existing SQL database and display data from tables etc, but when I try and edit the data using the detailsView it wont let me. No error msg, it just does not update the field.
However if I create a new record using the detailsView, I can edit it.
Its just older records that were created previously that it wont let me edit.
Is this a bug?, A compatibility issue?, Any Ideas?
