Auditing User And Security Related Activities In SQLServer
Jul 23, 2005
On the other database types, there is an audit capability in that you
record such items as
failed login attempts
attemtped access to tables user is not authroized to
changes to databse schema
changes to permissions
changes to logins (add, delete, lock, unlock, passwrod reset)
All I can find in the SQLServer documentation is the reference to
tracking failed logins when you set up a database, plus the Profiler's
activities.
Yes, I'm taking voer my first SQLServer database and have been asked to
make sure that this database is closely monitored for inappripriate
activity.
Questions:
1) Does SQLServer have this capability? (Sybase has this, which is
where I'm coming from)
2) Does SQLServer do this automatically or do I have to set up the
events to be tracked as happens with Sybase?
3) What commands are there for setting up these events to be tracked?
Someone had changed the SA password on one of my servers. I need to find out who did this. Can you tell me if there is any historical information kept on any of the system tables that can tell me who (what machine name) and when (date and time)this was done? Does anyone have a 3rd party or inhouse developed task/procedure to report this kind of security issues?
We are finding ourselves editing data within a sql database using tools such as MS Query, Access or VB. Is there anyway to log these edits? Auditing is set up within the application to log changes made by the users but not by third pary applications. ANy thoughts?
I would like to limit the role of an user In Visual Studio only to assign roles to other users for the cubes. Other than that the user should not be able to create / delete the exisiting cubes or dimensions.
Sybase and DB2 both have the capability of tracking user activities ata number of levels: invalid access attempts to databases, table, etc.;creation/deletion/modification of database objects/users/groups,grants/revokes.For MS SQLServer, the only setting that I've seen in the documentationis access attempts (none, fail only, etc.)The monitor program has the capability of tracking the events that Iwant to be monitored, but it seems as though these settings persistonly while the monitor program is running.I'd like these settings to persist permanently and the event records tobe sent to the system log.I can't seem to find the right term to get this information out of theMS Books On LIne.Help!
Hi, I need to write some T-SQL scripts to perform a database audit of several SQL Server 2000 databases that tracks all superuser logins and access to tables. I can do this in Oracle but I am lost with MS SQL Server. Can anyone point me in the right direction? Thanks!
has anybody investigated the cost of turning on AUDITING for the SQL servers? I am talking about enabling the entire C2 Security Audit mode. How much impact the auditing has on the database performance?
Is auditing for SQL 2005 any better, meaning less impact on performance?
Any sample, test, and/or numbers to support the arguments?
Please share any findings that you have or know. Thanks
I know that there are tools like Lumigent, but an wondering about theinternal facilities to track events such as table creation, securityoperations (add login, add role), and such.Under Sybase, there is a set of procedures that permit you to settheses events and to record the results for later extraction andanalysis.The Profiler seems to have a lot of the same functionality but thisappears to be more along the lines of running a monitor.Can the events be tracked without Profiler running?Can the events being tracked be recorded in the system of SQLServerlogs?
The requirement is to customize database admin activities by creating new user group.
Need to create a group of user / dbauser1 which will have restriction in seeing the data but they should be able to alter database - add / remove the data file , increase or decrease the data file space when required.
This requirement came we wanted to create a new dba group they should not be able to any user data / any table but increase / decrease / add / modify space etc.
We had been running SQL Server without any control of security (sincethe company is very small -100 employees). All of us know the adminpassword and has been accessing the database as admin. Our databaseserver crashed due to hardware failure twice last month and we lost alot of important data. Now the management is taking the control ofserver access seriously.SQL Enterprise manager is installed on many PCs and any one can deleteany database with a right click.My question is:1. Can the enterprise manager be installed on client's PC with alimited right (or as a user not as admin)?We need to limit the user's access of using the Enterprise Manager.In other words, how can we set this up for different users.2. How can we keep running SQL Server if one server fails?Clustering or Replication or Mirroring? OI would highly appreciate if you could direct me to any website orresources on how to set up security of SQL Server (2000 with the latestservice pack).Thanks a million in advance.Best regards,Mamun
Hi I was not able to connect to SQL Server machine. On examining the Error log (which was huge 53MB), I found the following messages that filled 95% of the logfile. Is this something to do with memory allocation.
Someone, please let me know what is going on. After the server reboot everything works fine. I am worrired that this message may occur again.
Thanks Machilu

i am testing some encryption scenarios ,in profiler the statements like "OPEN KEY" and all "Encrypt" and "Decrypt" functions are removed automaticly from the trace and replaced with a comment ,create a trace and try the code i attached , you will see in profiler trace that that all encryption related commands are commented out ,this is what expected.
but now go to the batch and comment out the "SELECT @rrr' statment, and run the batch ,this batch will fail beacuse "@rrr" is not declared, now go back to profiler and you will see that for the failed batch all the encryption command are NOT COMMENTED OUT !!! esspecially important is the visibility of the password of the open key command.
seems like a very dangerous bug to me!!!

CLIENT SIDE: If the query is reading from large table, (100 columns x 20000 rows) I have no problem getting results using SQL Query Analyzer on the Client side.
However, I am getting timeout problem from the client side application.
The query failed. The message from the database engine was: Microsoft OLE DB Provider for SQL Server: Timeout expired.
SERVER SIDE: I tested the same query on the server using the application. I can get the results.
ENVIRONMENT: Server machine: The Server : Windows 2003 Server SP2 Database Server : SQL Server 2000 €“ (8.00.2039 Standard Edition SP 2)
linkserver (OLE DB 9.0.0.3504 ) to FoxPro 9.0 SP1 table SQL Server Timeout Settings: Query time-out (sec, 0=unlimited)
Client machine: Windows XP SP2 : Windows Network Authentication SQL Server 2000 client
For some reason my environment doesn€™t like the outside application to connect to the server long time?
Do you have any idea how to fix this timeout problem? Do I need to configure DCOM or DTC?
I received the above error yesterday and haven't been able to trace it to any job or process running. We haven't implemented any changes to the server in the past few months, and it doesn't look to be a user-established connection, since the Client IP Address of the SSPI handshake error is from the server itself.
I logged this set of messages in SQL AgentServer error log:
Date 10.03.2008 6:15:19 PM Log SQL Server (Current - 11.03.2008 2:32:00 PM) Source Logon Message SSPI handshake failed with error code 0x80090304 while establishing a connection with integrated security; the connection has been closed. [CLIENT: <IP Address>]
I have a windows application that connects to a SQLExpress database hosted on a shared server. The client machines will run an interface software and interact with the info within SQL The SQL database isn't huge (50 megs) and all of the info is text. The interface application isn't too complex either, it was designed using VB.net05. I have a few setup questions:
1 - Is it best to use Windows or SQL authentiaction? Currently I am using Windows authentication and I have a user group setup on the DNS that is setup as a user for the SQL database. That has worked so far, but I've only had a few users logged in at one time so far. My plan was to add all DNS accounts that will use the software to the DNS user group, thus giving them access to the SQL database.
2 - I know this gets asked a TON, but I am interested in knowing how many users I should be able to support using the current setup. I have the one user acount setup for the DNS user group. The SQL table is not huge and it is all reading and writing text. The server is running Windows Server 03 and is a couple years old (not sure of exact specs).
Thanks for any help, I am still learning my way around SQL and it's great to have such a vast amount of support for the product.
How do you handle user level security with SQL Server 2005?
Say I have an HR database.
In Active Directory I have two groups: Managers, Employees.
Now in this HR Database I want to setup permissions in such a way that Managers can see all employees under them (but not other managers) and the employees can only see themselves.
(I'd have various levels of management defined in a table somewhere, so that each employee has a manager ID that links to another employee so that the CEO would be manager of everyone by working down the chain).
What I'm trying to understand is the best way to handle the permissions.
I'm not entirely clear on how to deal with that.
Would I use user chaining to do that, I wouldn't need impersonation (that's just for instances where you want dynamic SQL and it won't execute with user chaining, correct?)
Anyway, just looking for some general direction on this (obviously I need to get a good book it would seem).
Would I create a stored procedure that runs with EXECUTE AS permissions so that I'd have a non-interactive login it uses that has table access then all the other users have permission to execute the sproc?
So that sproc runs, pulls back a SELECT * FROM tbl_HRINFO and using a WHERE constraint limits who is returned WHERE SupervisorID = CurrentLoggedInEmployeeID ?
Also: How can I determine who is logged in and running the procedure, would the sproc use the SELECT USER_NAME command to see who was running it?
As you can see, I'm working from square one on all of this. Not sure if my posting entirely made sense, but hopefully someone can get me pointed in the right direction, thanks!
I have just reciently installed and started upgrading the last beta code to this beta and am having a problem conecting to my sqlinstance with the WebSite Configuration Tool.
I am struggling in calling an SSIS package programatically using the Microsoft.SqlServer.Dts.Runtime namespace.
I am succesfuly connecting to the package insofar as I am able to retrieve the package ID (GUID), but when I call package.Execute I get a 'login failed for user' error, which indicates a security problem.
My ASP.NET app is running as a domain user which has temporary 'SA' rights on the server where the package is hosted. In addition, I have set the protection level on the package to 'DontSaveSensitive'.
What am I missing to be able to execute the package remotely?
hi i have created a username and a password in sqlserver 2000 from logins in Enterprise manager and i permit him to the database i need to connect to .. and i check all server roles for that user and i make sqlserver authentication for him with a password and then i goto the udl file to connect to that database using that user it fails !! and says
"login failed for that user 'myusername' reason not associated with a trusted sqlserver connection"
while i use NT integrated security it works well so how can i connect to sqlserver using a username and a password
What is the diffrence between Sql Server Login and Sql server DatabaseUser?I want to put a funtionality in my application from where administartormake Application User.these application user will be made also in sqlserver..Now I am confuse here In sqlserver Login and UserWell I will make both for A new user of my application Sqlserver Loginand Sql server user,Plz help me What to do with It..
We have a a DTS package set up to run against another SQL Server. Using an integrated login is there a way to map an NT Authenticated users is the sql server login id mapping to this attached server. The DB we are going against only uses NT authentication to attach to.
I have an asp page that currently is creating a database and a userlogin for that database. After everything successfully (I thought)executed, I tried to change my connection properties for the serverand then login as this new user. It wouldn't allow me to, so I loggedback in as the administrator and looked at the properties for the newlogin. On the general tab, it had the user's default databasespecified as the new database that I had created in the asp page, butwhen I went to the database access tab, the database was not selected.So, I'm not sure how to set that in my script. I've done somesearching in BOL, but I can't figure it out. Also, if there's a wayto do this in a query, or stored procedure, will it also specify whattype of role the user has (public, db_owner, etc.)? Thanks.
I was just analysing the security which can be given to different users to access respective databases. So i tried, on my local server, to deny permission to myself to access Model database. After this i am not able to connect to my local server at all. Error: Permission denied. I am using windows authentication mode.
I have also deleted the local server registration, and re-registered it, but still the condition is same. Do i need to uninstall SQL Server completly to get rid of this prob.? I also registered a new data server, and there every thing is going fine. So now what do i do to get connected to my local server.
In some our dotabases I can see Schemas created with the same name as Domain User name (domainusername). Schema owner for those schemas is not dbo but the same user as in schema name. How this happens? Is any way to prevent or prohibit this?
What is the easiest way to find out what objects a security login has mapped to it? Something that would show all the explicit grants a specific user has.
Hi;My company just installed MS SQLServer 2005 ( see below the dottedline ).When a user logs into management studio all of the databases on theserver are displayed in the right hand column.What can we do to have only the databases the user has rights to,display?Thanks much in advance for any info.Steve-------------------------------------------------------------------Microsoft SQL Server Management Studio9.00.1399.00Microsoft Analysis Services Client Tools 2005.090.1399.00Microsoft Data Access Components (MDAC) 2000.085.1117.00(xpsp_sp2_rtm.040803-2158)Microsoft MSXML2.6 3.0 4.0 6.0Microsoft Internet Explorer7.0.5730.11Microsoft .NET Framework 2.0.50727.42Operating System5.1.2600

Note: View may use tables from multiple schemas example: dbo. Staging. ectÂ
By doing this, I want to achieve that this user Finance can see only Views created under Schema FinanceQuery and should not see any other objects (tables, Stored Procedures, Functions etc.)
