As far as i know all users that is assigned to "Public" database role by default cannot SELECT any tables which in the databases. But in my case i am restoring database from previous version of SQL Server 2005 to SQL Server 2008 R2.
The problem come when every new users that created can access all tables in the databases.
How to get "public" back to default permission settings?
Can you write a stored procedure to add a user to your DB and set the roles the user belongs to?
I want to write a stored proc. to add users and set roles so it can be used in code instead of doing it manually.
After the user has been added and their roles set, can you write another stored proc. to give you what roles they belong to?
I am working with a SQLServer installation where all public permissionshave been revoked from the system.I currently hold the securityadmin and sysadmin roles to perform mylogicall access control work (creating logins and adding users todatabases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!

I have setup a new SQL 2000 SP4 and internal auditor query about revoke permission from Public role and remove guest from all databases.
1. Can I revoke all default permissions (select on system tables in all DBs) from "Public" role? I am concern any error after such action.
2. I found that guest account in DB -- master, tempdb and msdb. According to Microsoft documents. The account should not remove and can't from master and tempdb. How about msdb?
Thanks,

Hi,
I have added two roles to sql server. One called Officeusers. The other AdminUsers
Added the appropriate logins to these roles. For example; james, john, ahmad to OfficeUsers and Mat, Nick to AdminUsers.
How can these roles be now used in a connectionstring? I can use each user login and his relevant password in a connectionstring to connect to sql server but not sure how/where/when the Roles come in to development.
i.e. do I need to use the role in the connectionstring? if so then what happens to the password.
Not quite clear about all these.
Thanks
We are looking to make our applications as secure as possible. I am interested in how well Application Roles work to make security tighter.
Have you used Application Roles. If you have, I'd like to know if it helped provide better security or not and if it did, how was it implmented in you production environment. I already know how to get it set up, I'm just wondering if it's really worth the trouble.
Thanks!
Under SSMS I see the "securityadmin" Server role. Where in SSMS can I find the actual list of permsisions granted to this role? (not just a generic description of what this role can do.)
TIA,
Barkingdog
I am facing a very weird issue in our SSAS database. We have several roles with 'Read definition' access. None of these roles are able to see data in the cubes. I have checked these roles over and over and there is no problem with the definition. Each of the roles have been given read access to Data Source, Cube and Dimensions.
The users are able to access the definition and structure of the cube i.e. they can see the measures & dimensions available but when they drag measures and dimension attributes in the browser (SSMS) OR execute an MDX - they get null values. The roles with 'Full Control (administrator)' access are able to see all the data without any issues.
I have tried the following:
1. Deleted all roles and re-created.
2. Created roles directly on SSAS DB.
3. Deployed all objects and processed the DB.
Each time only the admins are able to see the data.
I have developed a site on my local machine utilizing the built-in security/roles provides by ASP.NET 2.0. I am trying to publish the web application to a production server. It will publish correctly, however the ASPNETDB is not recognized. The folder app_data is created with the proper database files. My question is how do I set this up to use the data I have created in this database? I've searched on how to accomplish this but haven't found any definitive answers. I have found ScottGu's blog to be useful, but I was wondering if there is a different way.
1 - Do I push the data to a SQL Server install via SQL scripts?
2 - Can I link to the ASPNETDB that is created locally on my machine?
3 - If I make changes to the application and re-publish, is there a way to keep from overwriting the ASPNETDB on the server?
I am a unsure of how the built-in roles/security works when you are ready to push something to production. If someone wouldn't mind pointing me in the right direction, it would greatly be appreciated. Any literature, advice, links, etc.. would be great.
- Thanks

Hi,I'm
building an asp.net website using web developer express and I have a
SQL 2005 express install on the same machine. Using windows security,
everything works fine for development.Now I need to get it working at the client site, where the web server and SQL 2005 Express are on different machines.I'd
tried using windows authentication but that didn't work, probably
wasn't doing it correctly. I'd like to try SQL Authentication, at least temporarily, since I
can replicate that on my laptop at home easily I think.I created a new SQL login but was really baffled by the screens showing roles and schemas, etc. There's so many roles to choose from and wasn't sure if this new login needed to own any schemas. I
did turn on remote connections and mixed-mode authentication, the
probably now is my asp.net membership provider login page isn't
authenticating correctly, maybe my permissions are wrong on the
aspnet_..... tables for users, roles, profiles, etc. Any advice?thanks,Bruce
Roles Table:
RoleID, RoleName
<RoleID1>, Allow_ClientFolder
<RoleID2>, Allow_ClientReportA
<RoleID3>, Allow_ClientReportB
<RoleID4>, Allow_CompanyFolder
<RoleID5>, Allow_CompanyReportA
<RoleID6>, Allow_CompanyReportB
UsersInRoles Table:
UserID, RoleID
<UserID1>, <RoleID1>
<UserID1>, <RoleID2>
<UserID2>, <RoleID4>
<UserID2>, <RoleID5>
<UserID2>, <RoleID6>
<UserID2>, <RoleID1>
<UserID2>, <RoleID3>
e.g.
when the <UserID1> clicks on the "home" link show only "Client" folder and when <UserID1> clicks on the "Client" folder only "ClientReportA" will show.
Here is the accessable map for each user:
<UserID1>
Client
ClientReportA
<UserID2>
Client
ClientReportB
Company
CompanyReportA
CompanyReportB
Question:
What is the best way to implement CheckAccess? At first I thought I can access the item names and I can test authorization through that, but AceCollection contains operation permission of the accessing object.
I have two different roles, each one with a dax filter. One is for filtering users that access by Excel, and other for filtering users that access by Reporting Services, respectively:
=CONTAINS(FILTER(V_FILTRO_C;V_FILTRO_C[IDPerfilGrupo]<>7);V_FILTRO_C[iCursoCod];[SK_CURSO];V_D05_DIM_UTIL[DSC_LOGIN_USER];RIGHT(USERNAME();LEN(USERNAME())-SEARCH("";USERNAME())))
=CONTAINS(FILTER(V_FILTRO_C;V_FILTRO_C[IDPerfilGrupo]<>7);V_FILTRO_C[iCursoCod];[SK_CURSO];V_FILTRO_C[IDUtilizador];VALUE(CUSTOMDATA()))
To create only one role that serves Excel and Reporting Services users, is it viable to use only the || (OR) operator?, is there any other regard i should take?

Title: SQL Server Remote Data Source Function Contain
Unchecked Buffers
Date: 20 February 2002
Software: Microsoft SQL Server
Impact: Run code of attacker's choice on server
Max Risk: Moderate
Bulletin: MS02-007
Microsoft encourages customers to review the Security Bulletin at:
http://www.microsoft.com/technet/security/bulletin/MS02-007.asp.
- ----------------------------------------------------------------------
Issue:
======
One of the features of Structured Query Language (SQL) in
SQL Server 7.0 and 2000 is the ability to connect to remote data
sources. One capability of this feature is the ability to use
"ad hoc" connections to connect to remote data sources without
setting up a linked server for less-often used data-sources. This
is made possible through the use of OLE DB providers, which are
low-level data source providers. This capability is made possible
by invoking the OLE DB provider directly by name in a query to
connect to the remote data source.
An unchecked buffer exists in the handling of OLE DB provider names
in ad hoc connections. A buffer overrun could occur as a result and
could be used to either cause the SQL Server service to fail, or to
cause code to run in the security context of the SQL Server.
SQL Server can be configured to run in various security contexts,
and by default runs as a domain user. The precise privileges the
attacker could gain would depend on the specific security context
that the service runs in.
An attacker could exploit this vulnerability in one of two ways.
They could attempt to load and execute a database query that calls
one of the affected functions. Conversely, if a web-site or other
database front-end were configured to access and process arbitrary
queries, it could be possible for an attacker to provide inputs that
would cause the query to call one of the functions in question
with the appropriate malformed parameters.
Mitigating Factors:
====================
- The effect of exploiting the vulnerability would depend on the
specific configuration of the SQL Server service. SQL Server
can be configured to run in a security context chosen by the
administrator. By default, this context is as a domain user.
If the rule of least privilege has been followed, it would
minimize the amount of damage an attacker could achieve.
- Both vectors for exploiting the vulnerability could be blocked
by following best practices. Specifically, untrusted users
should not be able to load and execute queries of their choice
on a database server. In addition, publicly accessible database
queries should filter all inputs prior to processing.
Risk Rating:
============
- Internet systems: Moderate
- Intranet systems: Moderate
- Client systems: Moderate
Patch Availability:
===================
- A patch is available to fix this vulnerability. Please read the

What is the correct way to create a security group that allows the group members to Select (Read) the content of a database?
1. Create a security group in AD
2. Add the required members to the group
3. Add the security group as a login on the SQL server (Under Security>Logins)
4. Add the security group to the specific database with Grant in Connect and Select
I'm trying to get a SQL 7 and 6.5 DB to interact, but while there is no problem in SQL7, I cannot create a table called "Public" or a field called "Primary"!!
Does anyone know why this might be and if so where I might get a list of any other "invalid" names??
Thanks in advance,

Hello,
I am new user of SQL Server. I have some problems with these words. I want to make my database works in my specified permissions. I will specify permissions with schemas and these schema wants an owner. I want this owner should be my user. When creating a user it needs a valid login. I am selecting my login and it occurs and error says this login has an different user. I am specifying permissions with roles. But i can't make association all of them. I hope i told my problem to you as well. If you explain these words to me and tell me how can i do my database's works with my own schemas, users and roles i'll be grateful. Thanks for advices.
Happy coding...
Apologies if my post does not fit into this forum. I initially tried the SQL Server Data Access forum but I now think my question is more security related.
Is it possible for a web user who has been successfully authenticated with forms authentication to be authorised to use a SQL Server 2000 role depending on a particular ASP.NET 2.0 role that they have been authorised to use? I understand that that I can assign a SQL Server 2000 role to the ASPNET or NETWORK SERVICE account but this will grant access to anonymous web users to the database role. I can ensure that I only call stored procedures which access sensitive data in web pages that are in restricted by ASP.NET roles. However, it would be nice to also restrict stored procedures via the ASP.NET 2.0 Forms Authentication roles.
If this is not possible have you got any bright ideas how I could restrict access to stored procedures who are anonymous web users.
Many thanks,
Mark
I'm developing an ASP.NET2.0 application which accesses a SQL Server 2005 Express database. I plan to use integrated security for access to the database.
I'm confused about the relationships between Windows groups, the ASP.NET web.config file <allow roles=.../> and SQL Server roles.
I would like to create a Windows group to which I can assign multiple users and grant that group access to a Web Site using windows authentication and also grant that windows group access to the database my web application uses.
I have gotten the combination of Windows Authentication to the web site and to the database to work for a specific windows user but I am having trouble determining the combination of database security entities I must create to allow access to my database by members of the windows group.
For a Windows user:
1. Create Windows user
In SQL Express
2. CREATE LOGIN FROM WINDOWS WITH DEFAULT_DATABASE =
3. CREATE USER FOR LOGIN
4. CREATE ROLE
5. EXEC sp_addrolemember <role-name> <user-name>
For a Windows group, what would be the equivalent commands necessary to grant a windows group access to my database? Specifying the Windows Group name in sp_addrolemember does not appear to be sufficient even though the documentation states that a windows group name is a valid value for the member name argument.
After reading Books Online, I am still confused with Database Role vs Application role.
My intention is to control the end users' authority on the database, where the end users will access through Winforms client application. With proper assignment of schema and database roles to an user, I believe this will enough to control the permisison of an user.
If this is the case, why Application role exists? When and why should I use Application Role? How is it different from Fixed Database Role?
Hi! Can anyone say which ms sql server predefined roles are similar to the following oracle predefined roles: dba, connect, resource. I already know that sysadmin in MS SQL Server is the same as DBA in Oracle but what about the rest?
Thanks a lot.
I am in the process of locking down the SQL Server in an environment that is considered to be in production (pilot stages) and there is no staging or test environment that mirrors it. I need assistance in determining the server and database roles to assign to existing logins, most of which currently have sa and dbowner rights. Because it is not a development environment, I need to be sure that downgrading the server and/or database level permissions will not break any functionality.
I'm starting with the logins that have the SA fixed server role. These logins need to be able to install applications that require the use of a backend database, which will be stored on SQL Server. In addition, through the installation process a new login/password for the newly created database(s) is normally created. For the existing logins with the SA fixed server role, will downgrading to the securityadmin and dbcreator roles be sufficient to facilitate those needs, or are those too much/ too little? And should any user account ever be granted the SA role? If so, what questions could I ask to determine this need?
Since these install process for these applications usually prompt to install using SA or local system account to authenticate to SQL to create the new database(s), that account should have securityadmin and dbcreator roles to create the database and its tables, as well as add a new login to that database.
Please address this question, keeping in mind that the logins will only be performing the described actions, installing apps using SQL Server as the backend database and adding a login to that database (which may or may not be done during the installation process).
Thank you,

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
Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew
If jdoenew is missing in the 2nd db I will need to write entries like:
db1.usr_table.usr_name = jdoenew
db1.usr_table.password = tmppassword
db1.usr_table.active = 1
Hi,
I'm looking for some guidance/help regarding setting up a sa - lite account in SQL 2005. I need to give another admin rights to create/monitor maintenance plans, backup and restore databases, monitor performance/logins, but NOT be able to have any rights on several tables (and of course not being able to set user permissions).
I've tried using server and db roles but haven't been able to determine how to give someone w/o full sa rights access to maintenance plans.
If you can think of soemthing, please let m eknow.

I have MS SQL Server 2000 DB.
I have created a User and created some tables for the same.
I created a Role named A and granted Select Permissions for few tables to that roles.
When I created another Role named B and added this role (A) to B, the permissions are not being xferred to B. Bcos of which, if i assign an User to Role B, he is not able to select the tables for which permissions have been given thru role A.
Note : If i give assign directly the user to Role A, it is working. But i want to assign User to role A only thru B.
Hey ,
I have sql server 2000, and i am using Microsoft Application block.
I have Transaction Like...
SqlConnection conn = new SqlConnection(ASLConnectionString); conn.Open(); SqlTransaction Trans = conn.BeginTransaction(IsolationLevel.ReadUncommitted);
But If i have another process that try to read the Table if that old transaction running.. it wouldn't Allow me to read the DATA.
i tried Isolation level "snapshot" but that works under sql server 2005 only. so i can not use that. And i have some services that will run during day time.
So if anybody have solution to read the data from table...from sql server 2000 even if another transaction is running?
Please Give any guideline..Help will be appriciated.
thanks & regards,

I was wondering how to make a table read-only. I want to make a script that creates a table, adds some data to it, then makes the table read-only to prevent someone from accidentally changing the values.
