Hi,
I wonder if SQL Server 2005 supports row based security?
I need to set some users to see data filtered by a specific field and value...
Example: User XPTO only sees data about vendor code = '123'
Is this possible in the box?
Best Regards,
There is a STIG Check that does not allow grant "Connect SQL" directly to any logins except SQL System and the SA account. My way of resolving this is to do the following:
Step One:
We create a Server Role called SQL_APPLICATIONS – for the application accounts
We create a Server Role called SQL_DBA – for the DBA accounts
and give them direct “Connect SQL’ server permissions. MAKE THE ROLE OWNER = sysadmin (group)
Note: I think that creating a Server Role is only available starting with SQL Server 2012, but not sure. I am using SQL 2012
Step two:
I add the members (Logins - SQL & Windows) – in this case any application accounts and DBA accounts to the new roles respectively
Step three:
I remove the “Connect SQL” Permission from each Login
The first problem i noticed is that the maintenance plans failed with "The owner domainusername of job db_backup does not have server access.I am currently using a test system and wondered If you think I will have trouble with the application connecting when I try and implement on the production systems.
We have a new Win 2008 Enterprise x64 server running SQL 2008When we try to connect to the server using Windows Authentication, from a user account which is a domain administrator, we get the following message:"Token-based server access validation failed with an infrastructure error"What needs to be configured here for this to work ?

We are currently developing a crm that has the following main tables: client, sales, actions, contacts and employees with up to 4 million records. The db contains several other tables with extra information but these aren't relevant for this problem.
Clients have sales, contacts and actions. sales and actions can have seperate contacts as well, and contacts can be related to employees in a way.
Offcourse a security model was implemented but this only provides the option to hide or show all the records of these main tables. Now people noticed that it is a must to let people see for example only companies they created or do sales with. In other words access must be given at a record level.
The first thing that pops in my head is to create a client_security, sales_security, ... table that contains the employee_id and client_id or sales_id, or ... And add a join with one of these security tables for each select that is executed.
I wonder (because of the huge amount of data) if there isn't a better way to get this done?
Another possible issue that came to mind was, that when some data doesn't need protection or some people have the rigth to see everything, we would have to create the records in the security table anyways, resulting in probably hundreds of thousands of records.
Feedback on our solution (if we can call it that allready), or even keywords to find more about this issue via google (record based security really isn't the best description I guess) are most appreciated.
thx in advance.
First of all, I have never done any web-based stuff, so if thefollowing sounds ignorant, it's because I am!So far all our SQL Servers are accessed only over our network and weuse Windows authentication. Now the guy I'm working with on thedesign of our next stuff wants the two new databases (a transactionalone and my data warehouse) to be additionally accessed by web-basedapplications via our company intranet (NOT THE INTERNET). How do weauthenticate under these conditions? The webserver machine will betalking to the SQL Server ones, i.e. the databases will each be on thetheir own separate boxes. Can the webserver be a "user"? If so,and we want the actual users to have different privileges, then theweb-based apps have to manage that? Or is there a way for theweb-based apps to grab the Windows user and pass it to SQL Server?
View 7 Replies View RelatedI am attempting to set up a new user that has only the ability to run reports in the report manager.
I have created a new ActiveDirectory entry for DOMAINReportUser. I have a created a new folder with the reports, and have set this user as a Browser role on this directory, and all reports in the directory.
I have made it throught the security maze to gain access to these reports as this user, but I cannot dynamically run the reports. As the BUILTINAdministrator (content manager), I get a grayed background on the parameters and can run the reports. As this DOMAINReportUser, I get what looks like HTML parameter items, and cannot run a dynamic report. Even if I change the role of this user to Content Manager, I still cannot run a dynamic report.
How do you properly set up a user to be able to dynamically run, and only run, a report in Report Manager, and have this user only see reports in a single folder?
I have been fighting the security issues of creating a RS site and properly setting up access, and have yet to find a single site or person explaining the entire process in any coherant method.

Hi All,
I have a report running and I am attempting to assign role based security. I added a group to the site level security. The group I added contains child groups. It doesn't seem that report server is looking into the child groups to see if the logged in user is a member of the child group. Is there anyway to get this to work instead of adding all the groups directly? I suspect that report server is using cominterop and cominterop is not traversing the directory tree?
Thanks,
Darren
From Books Online Help:
In the role-based security model that is implemented for Reporting Services, users who are assigned to the Content Manager role can create and edit reports in Report Builder. Local administrators are automatically assigned to this role.
If you want other users to be able to work with a Report Builder report, you must create a role assignment for them that includes the default role "Report Consumer." Alternatively, you can create a custom role definition. As long as the customized role includes the "Consume reports" task, users who are assigned to that role will have sufficient permission to create and modify reports using Report Builder
---------
However, when I try to give a contact those rights, the "Report Builder" link still does not show up for my users. Is there any other place where I can examine the security rights to see why the Report Builder permission is not granted to my users?
I am currently developing a project that requires a server level permission for one stored procedure (ALTER ANY LOGIN)
To this effect, I plan to create a certificate, sign the stored procedure with it, import the certificate into the master DB and assign privileges.
I also understand that modification to the code invalidates the signature (after all thats the point of signing something).
But what about user defined functions and stored procedures referenced by the signed procedure? Does SQL server follow the dependancy chain and include referenced procedures in the signature? Or does the privilege assigned to the certificate not apply when the nested procedure is executed?
If this is not the case couldn't a restricted database user just alter a nested stored procedure they have been granted ALTER access to and make themselves SA or something?
So to sum up, do you have to duplicate the functionality of otherwise nested procedures into a certificate signed procedure to protect server security?
Hi all !
I have a question regarding the security of SQL Server 2005 Express Edition.
What securities options that SQL server 2005 EE provide for its users?
I know that after I deploy my website to a hosting company or a web
server, my database file will be on the net. That means everybody can
type in the file name and download my database file then open it. Just
like that. For example, my database filename is EXAMPLE.MDF. then,
someone just goto my website, say
http://www.cool.com/app_data/example.mdf, and download the database.
To prevent that to happen, what the securities options that available to me beside putting password on my database file?
Thanks for taking time to answer my question. Any help will be appreciated. Have a good day!

(1) To prevent unauthorised database access, is it ADEQUATE to delete / disable the BuiltInAdministrator login and the guest (database) user ?
(2) How can I delete / disable the BuiltInAdministrator login
in SQL Server 2005 Express ? It didn't allow me to disable or delete it.

HI,
I am just starting out with SQL Server 2005 and really getting in a muddle with al the security stuff.
It seems i have LOGINS, DATABASE USERS, Server Roles, Database Roles, SCHEMAS and somehow they all tie in together. I am using Microsoft Press "SQL Server 2005 Implementation and maintenance" but it really isn't doing a good job of explaining it to me.
Can anyone point me to a reference that clearly explains all this stuff?
HiI need to set security for row level but not based on Database user'slogin. It should be based on the user table login. For the particularuser I need to allow only the particular records to access insert,update delete and select.Let me explain clearlyFor example think we are using asp/asp.net websiteEg:www.test.comSo take this is our website and if you try this URL then you will get awindow for Login name and password.For example the Login name is windows user name (Here windows usermeans server windows user and not client) and windows password. So ifyou have login user id you can able to login in our site and we haveanother check. We have our own usertable this table consist all theuser login names and user rights. We will check the windows user whologin in our site has rights in the usertable I mean he is present inthe usertable if he is not present then we will display a message youhave no rights to access this site.If he has login id in our usertable then he allowed viewing ourpages. Still if he has the login id we will check the user who loginhas how much right to access to each page and the records of each tableits all depend on the user rights.So, here I need the row level security. For each and every table weneed to check the corresponding user and executing the record producelot of business logic problem for us.So after the user login we need automatically to set row levelsecurity for all the tables. Based on the user who login.So from there if we try select * from <tablename> then we can only ableto get the allowed records to select, insert, update, delete.Please can some one help how to solve this?Note:For some help you can refer the below URL (See in that they only givenabout the row level and column level security for each database usersnot for our required concept)http://www.microsoft.com/technet/pr...5/multisec.mspxThanks in advanceRams
View 1 Replies View RelatedHi All,
I have been building a database in SQL Server Express for some months now using the Windows level authentication login that has given me full access to everything in the database.
The time has now come where I need to create user accounts and grant permissions to specific stored procedures and I'm having trouble doing this.
Can anyone give me a brief rundown of the required T-SQL commands I need to set up a user account that can do nothing but run stored procs (not the system procs which apparently are being discontinued: http://msdn2.microsoft.com/en-us/library/ms182795.aspx).
So far I have:-
CREATE LOGIN db_test_user WITH PASSWORD = 'eXaMpL3Pwd
USE db_new
CREATE USER db_test_user
The above code executes successfully but when I try and connect (using Management Studio) I get error message 'The user is not associated with a trusted SQL Server connection (error 18452)' which means little to me.
I also tried creating a 'WITHOUT LOGIN' user for the database but could not figure out how to give it a password.
I don't know (/understand) roles/schemas and don't know if I really need them as I only need user access to specific stored procs. I don't ever want them to see the tables for example so they only need the most restricted access.
Can anyone help?
Thanks,
DG

Couple of questions for the SQL Server Guru's out there.
SQLServer 2005
Web Hosting Provider
Ok I am developing a Web application in ASP.NET with AJAX, etc. etc. It will be some time before it is ready to roll out. As a mockup I created the same application in Microsoft Access and Visual Basic (VS 2008), which I can link the tables to the hosting provider on the internet. Works very well and speed is very acceptable. The want to start utilizing it with the mockup distributed app that I created.
My question is, is how secure is the data that is moving from the local application to SQLServer 2005 with the web hosting provider ? Is there anything that I can do to increase security ?
Thanks, any thoughts ?
Appreciate any suggestions or comments.
Has anyone compiled a list of out of the box features to disable (like sql mail in 2000)? Or even just a general security checklist for 2005?
I'm looking for one similar to http://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/sp3sec04.mspx
Dear mems,
I have a problem, and i don't khow how to resolve, pls help me:
My server is Windows XP (not domain),
I work with SQL Server 2005, installed on my server,
I configurate my SQL SERVER connection is "Windows Authentication mode",
I add user "MyComputerguest" to MyServerSecutityLogins to accept connections from local network
I have many databases: Db1, Db2, Db3...
But, I don't know to configurate my SQL Server to achive these:
1) My clients using "SQL Server Managment Studio" connect to Databases Db2, Db3... on my Server, they can expand, modify, add new all Tables, Sp, functions of Db2, Db3.
2) My clients are not allow to access Db1.
2) My clients can add new Databases Db4, Db5, Db6... in the future and they have full permission on every Database which they create without my interfere.
Best regard,
if you run the following script it takes access from the windows admin from getting into sql server through windows auth. The issue is that the files that are attached logging as SA after that are read only. Is there any solution? When you try and switch the file to read write sql server gives an error saying that it cant read the mdf and ldf--gives a windows access error....
USE [master]
GO
IF EXISTS (SELECT * FROM sys.server_principals WHERE name = N'BUILTINUsers')

The user is not associated with a trusted mysql server connection." followed by an ip address

Hi everyone,
I'm currently investigating the security improvements of SQL Server 2005. I've got some problems with the schemas introduced in SQL 2005 and security settings.
For my test I've created two schemas: UserManagement and Sales. A user "test" is attached to the UserManagement schema. There's a table Sales.Users containing a list of users (varchar) and a stored procedure named UserManagement.AddUser that can be executed by the UserManagement schema (GRANT EXECUTE, so "test" can execute the SP). UserManagement.AddUser simply inserts a new row into Sales.Users.
Because the Sales schema doesn't contain any user, nobody (except the sysadmin, of course) can do a INSERT/SELECT/DELETE in the Sales.Users table. As expected, the following SQL statement fails:
EXECUTE AS LOGIN='machine est';
INSERT INTO Sales.Users VALUES('Test User');
INSERT was not allowed: object 'Users', database 'test', schema 'Sales'.
The second way of inserting rows into Sales.Users is to execute the stored proc UserManagement.AddUser:
CREATE PROCEDURE [UserManagement].[AddUser]
WITH EXECUTE AS CALLER
AS
INSERT INTO Sales.Users VALUES('Test User');
The user "test" can execute this sproc without problems:
EXECUTE AS LOGIN='machine est';
EXECUTE UserManagement.AddUser;
(1 row(s) affected)To my astonishment the INSERT statement inside the stored proc does execute - although UserManagement.AddUser and Sales.Users are two different schemas. Why is that, is there a chaining happening? To my understanding SQL Server should test INSERT rights on Sales.Users for the UserManagement schema and deny the INSERT statement because UserManagement isn't allowed to INSERT in the Sales schema.
Any ideas? Help regarding the issue is greatly appreciated.
Best regards,
Alex
We have experienced an issue with back backup / restore of a database originating from SQL Server 2000 to SQL Server 2003.
We have the following setup:
SQL Server 2000
- DatabaseA
- asdfUser (SQL User)
- asdfUser is (dbowner) of DatabaseA
- DatabaseB
- asdfUser (SQL User)
- asdfUser is (dbowner) of DatabaseB
SQL Server 2005 Standard
-asdfUser is NOT Setup as a user yet.
-We restore DatabaseA and DatabaseB to the SQL Server 2005 Standard. The databases are restored with the security permissions of asdfUser being the DB Owner of DatabaseA and DatabaseB.
-We create a new SQL user named asdfUser on the SQL Server 2005 box. We then try to add the UserMapping of DBOWNER for the DatabaseA and DatabaseB. We receive an error message stating that the asdfUser already have permissions to the databases. We proceed with the user creation without those permissions.
-We proceed to the login properties of the asdfuser and view their UserMappings. The asdfUser does not have access to DatabaseA or DatabaseB. We then add the UserMapping of DBOWNER to both DatabaseA and DatabaseB. We Try to select OK and we receive an error message that states that the user already has those permissions.
-When we query the UserID's of the asdfUser that is in the database and the UserID of the asdfUser that is created, they are two different values.
I assume this is a bug... any word on a fix?
I have a business requirement to build a tabular data model, where I need to mask information of other Agents from a given Agent but I still need to show the overall sales of the given product.
For eg: IF an Agent is in APAC region he should see APAC region sales and also should be able see the sales of the same product in other region without knowing region specific break down.
For Agent "Tom" in APAC region, the numbers will look like this
APAC_Sales = 100,000
Other_Sales = 500,000
And if "John" is in NA region, then the number will look like this for him
NA_Sales = 200,000
Other_Sales = 400,000
I wanted to create "Roles" based on the Region, so all the agents belong to "APAC" region will have same view as Tom and "NA" region agents will have John's view.

We have upgraded to SQL Server 2005 and Window 2003 from SQL Server 2000 and Windows 2000, and have been having all kinds of problems with security of our web applications. We have been forced to put the system account of the web server as a user in the database in order for the web applications to work. We have lost the ability to control security at the user/role level. Is this the way security is going to work in Windows 2003/SQL Server 2005? How do I use integrated security so that I can secure web pages and database objects?
Thanks

Here is my situation: I am creating a database driven ASP.Net web application that will be used over the internet. My ASP.Net application connects to my SQL server 2005 database/server by using a SQL server login. I am using the DPAPI API to encrypt my connection stings with a hidden entropy value for extra security. I am using the SQL login for obvious reasons, as my users will not have a windows login.
What I am trying to do: I want to limit this SQL login account to be able to just run/execute stored procedures and NOT access the tables or views directly. In my ASP.Net application I am using the MS applications data block, and I am using stored procedures for every single database access action. There is no inline SQL being executed from my web application.
What I have tried so far:
I created a new schema and made the above SQL login account owner of this schema. I then granted "Execute" permissions to the SQL login and DENY permissions to all other permissions.
I created an database role with "Execute" only permissions and DENY permissions to all other permissions.
What Happened: In BOTH of the above scenarios I tested a direct SQL statement against one of my tables, from my ASP.Net application and I was able retrieve data back, NOT GOOD, exactly what I am trying to STOP.
If someone could give me (Step-by-Step) guide on how to setup the situation I am looking for, I would be very grateful!
Thanks to all that help!
