Any Security Issues Around Using SELECT Only Permissions

Jan 17, 2008

I have access to an SQL server 2000 or 2005 database and only required access to SELECT data from certain tables. I have been given access to the database for my windows form application which runs dynamic SQL statements. The statements are stored in xml files and parameters inserted at runtime. There is the possibility of encrypting the xml file.

I wanted to know if someone was to add a delete, insert or malicious command into the xml file would SQL server still run the command even though the User permission is only for SELECT?

Your help is appreciated

Security && Permissions

Nov 7, 2006

Hi
 I have a SQL Server 2005 Express database, and I'm trying to add a new user to it... however I thought I'd given it the correct permissions, but it's saying it hasn't got SELECT permissions on all of the tables.  How do I grant a user the neccessary permissions on a database to just do standard select, updates, deletes and inserts and nothing else?
 Thanks, Paul

Views Security And Permissions

May 1, 2008

I have a database with two views in it.

As it is right now i have two sql logins one for readers and one for modifiers. I need to open the database up to windows auth.

I want users to only be able to see views and not the tables. I also want users to be able to modify the table if they are in one view but not in the other views. How would i do this? I have limited experience with permissions like this.

How To Script Security Permissions?

Jul 23, 2005

I have a very large table that is refreshed periodically. Since it'sso big, I do a 'drop table', 'create table', 'create index' then a bulkload. It's much faster than doing a 'delete from'. I also do a'shrinkdb' as part of this process.The problem, however, is that the user permissions are also dropped inthis process. So, how can I script the user permissions? For example,how do I give 'MyUser' select access to 'MyTable' in 'MyDB'? Manythanks!!Eben YongJoin Bytes!

Trigger Security/permissions

Aug 3, 2006

Hi,

I'm not sure if this is the right forum, but I believe it's the closest to my question (if not, please let me know).

I am wondering if it's possible to perform an INSERT to another table in another database from within a trigger. For example:

CREATE TRIGGER inserted_mytable ON mytable
FOR INSERT
AS

DECLARE @rc INT
SELECT @rc = @@ROWCOUNT
IF @rc = 0 RETURN

INSERT INTO [OtherDB].[dbo].mytable2
SELECT *
FROM inserted

Both mytable and mytable2 have the exact same structure. What appears to be happening is that the INSERT statement locks up the mytable database. Is there a permissions problem here, or is this just not possible?

Thanks,

Restrict ASP.NET App DB Permissions Using Integrated Security

Mar 6, 2007

How might I Restrict ASP.NET app DB permissions using Integrated Security?

I can see how it's done with SQL Authentication, but I'd prefer to do it with Windows Authentication.

Is it a matter of restricting the permissions of the general ASP.NET user (€œNT AUTHORITYNETWORK SERVICE€?)...seems like it might affect too much.

Or can I have a Windows user/identity/account that is specific to a single ASP.NET Application?

Any guidance on this would be appreciated.

Thanks!

SQL Security :: How To Set Permissions For A User On X And Y Schema

Oct 22, 2015

I need to provide a User with below permissions:

1. Ability to read and write records in tables in both the X schema and Y schema
2. Ability to read metadata about objects in the X and Y schema
3. Ability to execute stored procedures in the X and Y schema
4. Ability to create and update the necessary schema objects used by X, including but not limited to tables, views, and indexes
5. CREATE FUNCTION permission
6. ALTER and EXECUTE permissions on the X schema
7. VIEW DEFINITION permission on the X and Y schemas to enable view export. 

For the point 1, I will assign db_datareader,db_datawriter database roles to the user

For the point 2, when I have searched web, I found out ReadDefinition permission should be granted. I could find only viewDefinition but not ReadDefinition.

For the point 3, 'USE DataBaseName GRANT EXECUTE TO User; Go' - does this sql suffice?

For the point 4, I am not sure what should be done.

For the point 5, 'USE DataBaseName GRANT CREATE FUNCTION TO User; Go' - I guess this will work

For the point 6, Can I use same SQL as point 3 including ALTER ?

For the point 7, 'USE DataBaseName GRANT VIEW DEFINITION TO User; Go'

Security.Permissions.SecurityPermission, Mscorlib

Aug 12, 2006

I am now developing a stored procedure in SQL server 2005 that can retrieve the serial no. of the harddisk(C:) in the server machine.

I have created a DLL call HDinfo that can be used by other application. Then I added to SQL Server 2005 by using

CREATE ASSEMBLY HDinfo
FROM 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBinnHDinfo.dll'
WITH PERMISSION_SET = UNSAFE

After I have added to the SQL server, I can call it in the C# CLR Project and use the method inside. However, when I executed the stored procedure in SQL server by

exec dbo.PrintToday

[PrintToday is a method that return the serial number of the harddisk]

it shows some error message,

A .NET Framework error occurred during execution of user defined routine or aggregate 'PrintToday':
System.TypeInitializationException: The type initializer for 'System.Management.ManagementPath' threw an exception. ---> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I would like to ask do I need to set some permissions for getting the serial number in SQL Server? Or...this method is not support in SQL server 2005?

 

Thank you very much!!~~

DTS & Security: Permissions Required To Launch Package

Jan 9, 2001

I have prepared several DTS packages which must be launched by a custom external application. What is the best way to provide access to this application? What are the minimum security requirements? Currently, they are local packages; I understand that some utility is offered by saving them as .DTS files, but I don't know the pros & cons. Are there advantages to using the Repository? The app should be able to do its work from a different box on the same network as the server. (Ultra-super-secret security isn't an issue, but I don't want to have give our developers sa-level access unless necessary.)

Security Admin On A Server With NO Public Permissions

Sep 21, 2005

I am working with a SQLServer installation where all public permissionshave been revoked from the system.I currently hold the securityadmin and sysadmin roles to perform mylogicall access control work (creating logins and adding users todatabases and changing group memberships.)There has been a question as to whether or not I need the sysadmin roleto do my job, so we tried an experiment in dropping the sysadmin rolefrom my id.With no public permissions, I see no user information on the server,which really limits my ability to do the job.Has anyone ever worked with a super-locked-down server without thesysadmin role for doing security admin work?What I'm looking for is hopefully SQL to perform the access privilegesneeded for the security admin role by itself.Thanks in advance!

SQL Security :: Permissions Disappearing From Tables And Views

Feb 26, 2014

As a CRM person, I sometimes have to update the database to cope with custom reports that I have written. Usually, I will

Go into SQL Server Management Studio 2008Open the database
Locate either the table or the view
Right click on permissions.
Add in the role or user that's needed
Grant them Select permissions

This allows the report in CRM to access the database and this works.

The problem I have is that after a certain amount of time, the user or role will disappear from the permissions meaning that the report will not run. Sometimes, this can be as soon as a couple of days or it can be months. It happens on views more than tables and, whilst it's not too difficult to put the permissions back, it is annoying for the users.

I don't use SQL Server Management Studio very regularly, only to write a few queries and set up these permissions so I'm not sure if there's anything else in there that might be doing this.

SQL Server Setup Failed To Modify Security Permissions

Feb 19, 2007

Last night at home on my 64 bit Vista machine, I encountered the same error 29506 that said that the management studio express could not be installed.  I looked up the error message and below is what I received.  I also installed the 64 bit .net framework which installed just fine before trying to install the SSSME.

I followed the instructions below but this did not seem to make a difference.  However, I did not reboot after applying new permissions.  I have installed this software a few times now on 32 bit machines for both XP and RC1 Vista, and have not had a problem.  Last night, I did use the 64 bit version.  Also, there is no data file yet because after the install it rolls back, so I gave myself Full permissions on the SQL server directory which should include all sub directories, right?  Thanks, Teri
Error 29506.
SQL Server Setup failed to modify security permissions on file Drive:Program FilesMicrosoft SQL ServerMSSQL.xMSSQLData for user SYSTEM. To proceed, verify that the account and domain running SQL Server Setup exist, that the account running SQL Server Setup has administrator privileges, and that exists on the destination drive.

Note A SQL Server service pack refers to SQL Server 2005 Service Pack 1 (SP1) and later service packs.
CAUSE
This problem occurs because one or more data files exist that do not have the required permissions. By default, the Full Control permission of the Administrators group is granted to the data file when you create a database. If the permission of this group is removed from the data file, the SQL Server 2005 service pack setup will fail.
RESOLUTION
To resolve this problem, grant the Full Control permission to the Administrators group on all data files and on the Data folder. To grant the Full Control permission to the data files, follow these steps:



1.
Locate the folder that contains the data files. By default, these files are located in the following folder:
C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData

2.
Right-click the data file that has no required permissions for the Administrators group, and then click Properties.

3.
If the Administrators group is not in the Group or user names list, click Add, type Administrators, and then click OK.

4.
Click Administrators in the Group or user names list, and then click to select the Allow check box for the Full Control item in the Permissions for Administrators list.Note If the files in the Data folder have an orphan owner, you have to take ownership of the files and then grant the Full Control permission to the files. We recommend that you do not change the default permissions for the data files.

Row-level Security: Permissions Required On Base Table?

Jun 2, 2007

I'm implementing row-level security in a SQL Server database that uses Microsoft Access for the front end. I'm using a UDF (a view behaves the same way) to restrict access to specific rows of a base table based on membership in a role. According to the reading I've done, if the base table has DENY ALL permissions for the role, and the UDF has GRANT ALL, members of the role should be able to update records in the base table via the UDF, without having direct access to the base table. However, I find that unless I grant appropriate permissions on the base table, the user is unable to update the table via the UDF.



Is this expected behavior? Nothing I've read suggests I should have to grant permissions on the columns of the base table.

Error 29506. SQL Server Setup Failed To Modify Security Permissions

Aug 15, 2007

Received the following error while installing SP2

MSI (s) (D8!A0) [21:07:09:062]: Product: Microsoft SQL Server 2005 -- Error 29506. SQL Server Setup failed to modify security permissions on file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData for user Administrator. To proceed, verify that the account and domain running SQL Server Setup exist, that the account running SQL Server Setup has administrator privileges, and that exists on the destination drive.

Tried running install with a domain account and local account with same results.

Based on the error message, I checked permission on the drive and still received the same error.

Followed resolution based on KB 916766, this did not resolve the error.

Only possible resolution I found was to disable UAP, reboot and retry the install. This will be done as a last resort, but any other suggestion will be appreciated.


Many Thanks

Why Not Allow Select Permissions To Table

May 19, 2004

I have always set up sql security for reporting to have select permissions on the tables to be used in the reports. I'm told by my coworkers that this is not advisable and I should only use stored procedures for reporting. I use stored procedures for all application duties, insert/update/delete etc but find with reporting it's much easier to just provide select permission to the tables. The only drawback to my method appears to me to be a user could conceivably view all data in tables while with the stored procedure one can limit what is being viewed. Anything else I'm missing? Thanks.

Reseting Select Permissions For Public Role

Sep 13, 2004

Every night, there are some stored procedures that run to recreate tables so that the information in the table is updated. After the tables are droped and recreated I have to go in and check the select box under the permissions for the public role. If i don't do this users will not be able to select from theres tables.

What can I do so that users are able to select from these tables after they are created?

Would you be able to specify the select permissions for the public role in the script that creates the table or run a script that gives all those tables select permissions for the public role?

All help is appreciated.

SELECT Permissions Problem - Not With A Stored Procedure

May 12, 2008

I'm getting a strange error and I've run out of places to look to fix it. I'm running the following statement when connected as APP_USER in SQL Server Managment Studio (SSMS).


select * from cs.dbo.order

I get the following error.


Msg 229, Level 14, State 5, Line 1

SELECT permission denied on object 'ORDER', database 'CS', schema 'dbo'.

Even after running the following as SA, the result is the same


grant select on cs.dbo.order to APP_USER

Running the query as SA or as a user with datareader permissions works fine. The APP_USER can also select from another table in the same database and schema without error. The APP_USER has SELECT, INSERT, and UDPATE permissions on the table. A second user with only SELECT gets the same error.

I've tried removing and reapplying the permissions with no luck.

Searching for this problem all the examples I find are related to stored procedures (permissions not working the same on dynamic SQL). However, I'm not using a stored procedure. This is plain SQL in a query window in SSMS.

Any help on where else to look for the cause of this would be greatly appreciated.

SQL Security :: Database Level Audit - Query Parameters For SELECT Statements

What I see through the Audit Logs is something like:

SELECT * FROM myTable WHERE name='@1'

Table Permissions Versus View Permissions

Aug 2, 2006

Using SQL Server 2k5 sp1, Is there a way to deny users access to a specific column in a table and deny that same column to all stored procedures and views that use that column? I have a password field in a database in which I do not want anyone to have select permissions on (except one user). I denied access in the table itself, however the views still allow for the user to select that password. I know I can go through and set this on a view by view basis, but I am looking for something a little more global.
