Restricting Users To Data In A Database.

Apr 29, 2008

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
+
+--------------------------+

SQL Security :: Users Are Able To Login To Server Without Any Login Names Or Being Part Of A Group

Jun 5, 2015

I have a server that has 20 databases . I have tested with few users with different level of access and all of them were able to connect to the server and also see, select, update , delete from a particular database which is kind of weird because they do not have a user login associated or mapped to that database. I checked and no user is part of any group in AD that would give them permission to connect . I need a query that would find the permission path of a user. I already queried with xp_logininfo but I am not getting any thing.

SQL Security :: Adding 3 Users To A Login?

Oct 28, 2015

I have to give three users read access to a database.  My manager told me to map them to a User called "zxDatabase.Read.ug".  I scripted  the User and got this...

CREATE
USER[zxDatabase.Read.ug]
FORLOGIN[zxDatabase.Read.ug]

I don't see a Login at the server level named zxDatabase.Read.ug, so this is confusing.  Where is this login in SSMS?

How do I map my three users to user zxDatabase.Read.ug. Or am I not understanding correctly?  Do I just add there windows login to the database as Users and configure them the same as zxDatabase.Read.ug

SQL 2012 :: Restricting What A User Can View In SSMS

Feb 5, 2015

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.

Difference Between Database -- &&> Users And Security --&&> Users

Nov 28, 2006

Hi Team,

In SQL Enterprise Manager, when we expand "Database -->Users", we see the

users there. When we expand "Security --> logins" we see the same users there.

Can you differentiate these two.

Thanks

SQL Security :: How To Organize And Secure Database Users

Apr 21, 2015

Is there any way in which I could distinguish a group of Database users from the other users. Say for e.g. store the Database users hierarchically, etc. Adding a Prefix/Suffix to the user name as a distinguish-er will not work in my case. I want to restrict the deletion of these Database users. Even the login with sysadmin or serveradmin rights should not be able to DROP those Database users.

Schema-level Security For Multiple Users In One Database

Apr 17, 2007



My developers would like a 'sandbox' database with full ddl and dml permissions, however, they do not want others to read/change/drop their objects. With SQL 2005, can DDL permissions be granted to a user at the schema level? I'd rather not set up a database for each developer.

SQL 2012 :: Secure Login To Database For Web Users?

Feb 21, 2014

We build up a new website in .net mvc 4.0 on a w2012 server with MSSQL 2012 database.We use windows autentification and normal anonymous access through NT AUTHORITYIUSR who is also a login in the database.But we make extra login possibility for users who are registered and they can insert and modify data in some tables in the database. And I'am afraid of giving NT AUTHORITYIUSR insert and update for some column in tables.I think of set up a new login for the database. Run a new connection string on login and set up special permission for that extra user on the database, and let the user become a member of the ordinary user on the database.

SQL 2012 :: Migrating Database To New Server - Map Login To Users

Mar 10, 2014

I am migrating a database TESTDB from SQL 2008R2 to a new server running SQL Server 2012.

Management has decided the current sql users should have "better" user names. So the login and username "BadUsername" on the old server should be called "GoodUserName". Goodusername should have the same permissions as Badusername.

I have now restored a backup from the old server to the new server.

I used the following script for creating the login:

CREATE LOGIN [GoodUserName] WITH PASSWORD=N'difficultpassword', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO

Then I run the following script:

ALTER USER Badusername WITH LOGIN = GoodUserName, NAME = GoodUserName

But the results are not what I wanted. I now have two database users: Badusername and GoodUserName. I would have preferred if BadUserName was "replaced" by GoodUserName, but it won't be a problem if I have to delete badusername manually. Worser is that GoodUserName have NOT "inherited" any permissions from Badusername.

Is there an easy way to transfer permissions or do I need to loop through the permissions of badusername and apply those to badusername?

Security For Row Level But Not Based On Database User's Login

Apr 21, 2006

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

SQL Security :: Using Contained Database Login To Connect To Server Via Excel

Jul 29, 2015

I have a SQL Server 2014 database that is partially contained.  I am trying to connect to the database via Excel using a contained user login.  When I choose Data - Other Sources - From SQL Server, I get the Data Connection Wizard window to Connect to the Server.

This window allows me to enter the server name and a User Name and Password (for SQL authentication), however it does not allow me to specify a database.  When I click the Next button, I get a 'login failed' error which I assume is happening because the contained user is not a SQL login.

I have the same issue trying to create an ODBC connection using the ODBC Data Source Administrator. 

Is there another way for me to connect to a SQL Server database using a contained login with Excel?

SQL Security :: Making Data Change In Read Only Database Without Letting Other Users Update Data

Aug 6, 2015

I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.

For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?

Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.

The code;

use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate

use xxx
update  tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

SSMS - Intermittent Login Failure

Mar 31, 2006

I have a 2000 / 2005 side-by-side installation on our test server.

To login to 2005 with SSMS, the connect string is

hostname/SQL2005, 1434

There's a WiFi network connecting my client PC to the network.

SSMS fails to login frequently. I need to exit SSMS, then login again. It'll work.

A new problem today - after successful login, I can't open a project and login successfully. Error messages states "Failed to Login".

Any tips?

SQL Security :: Windows Server Firewall Not Blocking SSMS Access From All IPs

Nov 6, 2015

We have a hosted server with a website and sql server 2008 on.

The windows firewall is turned on for all networks / profiles and says its blocking incoming traffic.

I see a lot of login attempts in the windows logs where hackers are trying to connect to it. I can also access it via SSMS from multiple external ips.

Everywhere I've googled says that incoming traffic should be blocked by default by the firewall.

There are no obvious rules that allow SSMS access.

If I do a blocking rule on inbound rules for a single ip that does work, blocking it from that ip, but any other ip's can still connect.

In the firewall log file I can see the allowed connections on port 1433 etc. other than the dropped one from the test blocking rule.

Connect To Remote Instance Of SSIS From SSMS Using SQL Login?

May 25, 2007

I have installed a SQL Server 2005 Standard Edition instance with SSIS on Window Server 2003 x64. From my PC, I am able to connect to the Integration Services on the server using Windows Authentication but not with a local SQL login - and the option to change authentication methods is greyed out.



Is it possible to remotely connect to SSIS using a SQL login rather than a Windows login? If so, any ideas or references for configuring it as such?



Thanks.

I have a windows 2008 with SQL Server 2008 R2 VM on Azure. I am trying to connect to the SQL server for the first time using SSMS, but have not been able it. I have a VPN tunnel, so I am connecting using Windows authentication. The error I get back from SSMS is:

I have done the following:

- created an endpoint for port 1433
- opened port 1433 in the firewall
- Ran the MSSQLSERVER service as the build-in users Network Services, Local System, and Local Service, and as a local and domain administrator, with the same exact result each time.
- I get the same result trying to connect locally or remotely.
- I get the same result trying to connect using sqlcmd.
