What Type Of Security Do I Need Here?

May 2, 2007

I'm developing a SQL Server 2005 application that is using a MS Access Data Project as the front end. This application deals with sensitive data such as salary information and related calculations. I would like to prevent anyone but the user who comes through the Access app, from seeing any columns in the database, and from viewing or executing any procedures or functions. This includes DBAs.



I'm not sure of the best way to approach this, or what type or level of security would fit in this situation.



Thanks.

In What Sql Server Data Type Would You Store Security Ids?

Nov 5, 2007

security ids seem to be made up of at least 3 32 bit unsigned numbers and a few smaller numbers. We believe their lengths vary. We dont mind dropping the "S" from the front. What data type do you recommend be used for their storage? We expect only limited joins and user visibility on this column. We may wish to create an index on this column. We think varchar and varbinary are the two major choices.

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

Aug 21, 2006

I have created a windows library control that accesses a local sql database

I tried the following strings for connecting

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"



I am not running the webpage in a virtual directory but in

C:Inetpubwwwrootusercontrol

and I have a simple index.html that tries to read from an sql db but throws

the error

System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,

etc etc

The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted


I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security

I think that a windows form connecting to a sql database running in a webpage should be simple

to configure what am I missing?

SSRS -- Security Filter And Model Item Security Setting

Jul 31, 2007



Hi,


I have posted this issue for a week, haven't got any reply yet, I posted it again and desperately need your help.


The article http://msdn2.microsoft.com/en-us/library/ms365343.aspx says:
Model Item Security can be set for differnt security filters, but when I use SQL Server Management Studio to set Model Item Security, it seems "Permissions" property surpass "Model Item Security" property. -- My report server is using Custom Authentication.



For example, in "Permissions" property of the model, if I checked "Use these roles for each group or user account" without setting any user or group, no matter what users I added to "Model Item Security" with "Secure individual model items independently for this model" checked, NO one user can see the model on report manager and report builder;

in above situation, if I added "user1" and gave role such as "Browser" role to "user1" in "Permissions" property, if I checked "Secure individual model items independently for this model" in "Model Item Security" property, even I did NOT grant "user1" to root model and any entities under the model, the "user1" is able to access the model and all entities in report builder.



My question is on the same report model, how to set "AdminFilter" (empty security filter) for administrator permissions and set "GeneralFilter" (filtered on UserID) for general user based on their UserID?


The article also says:

"Security filters are always applied, even for users who have Content Manager or Administrator permissions to the model. To allow administrators or other users to see all rows of an entity on which row-level security is defined, you can create an empty security filter (which always returns True) and then use the filter to grant those users access to all the rows."



So I defined 2 filters "GeneralFilter" and "AdminFilter" for "Staff" entity for my report model "SSRSModel", I expect after I deployed the report model, the administrator users use report builder to build reports with all rows available, and the non-admin users can only see rows based on their UserID.



I can only get one result at a time but not both:

either the rows are filtered or not filtered at all, no matter how I set the "SecurityFilter" for the entity: I tried setting both "AdminFilter" and "GeneralFilter" for SecurityFilter at the same time, combination of "DefaultSecurityFilter" and "SecurityFilter", or one at a time.



Your help is highly appreciated!

Setup Of Security / Integrated Win Security On Vista

Jul 6, 2007

I have Sql Server Express installed on Vista (service pack 2)

I have Visual Studio 2005 with an application that I'm trying to access it with within a WCF service.



The login ID of the service is added to the database.

The database has remote access turned on.

The ID is granted access to all databases within the server.

The thread is being set with WindowsProvider and the services set their thread to WindowsProvider.

The dataserver is set with using Windows Authentication for security.



When I open my connection to the database, though, it reports the typically useless message that the connection is not allowed and that the server may not allow remote connections.



How to I get past this? I've done everything right.

Float Type Steals My Decimal Points And Money Type Kills My Query

Mar 28, 2008

Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1

If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.

anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?

Implement Time Interval Type In Form Of User Defined Type

Dec 7, 2011

Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:

1/4/2006:1/10/2006

which would mean the time period from 1/4 to 1/10.

Bulk Insert Task Failing On Data Type Conversion For A Destination Column Of Type Bit

Jul 6, 2006

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.

I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.

I hope someone can help me work through this.

Thanks in advance,

SK

Transport Security Vs Dialog Security

Aug 3, 2006

In an environment where there are many initaitors speaking to a central target with frowarders in between, from what i can understand this best policy is to disable encryption on the endpoints, since dialog encryption will be enforced this is all that is really required, is this correct.

If the endpoints used encryption the message would need to be encrypted and decrypted at each forwarder resulting in slower perfromance, where as dialog encryption would only encrypt at the sender and decrypt at the target, so is this the best way to go?

Secondly is it best practice to open a dialog initally and send messages over this dialog for years never ending the conversation? This way the services only have to authenticate eachother once, if there are no reboots etc that is of course.

I would think performance wise sending each message and ending the conversation each time is a much greater overhead ? So would it be best practice to keep dialogs open and keep sending messages ?

Initally when i was learning service broker i thought that one must send a message and end the dialog until the next message, but i think the other way is the best option ?

Is this correct ?

Thanx

Dialogue Security Vs Transport Security

Feb 19, 2007

Hi

I'm designing a distributed application where I will have SQL Server 2005 distributed databases replicating data to my central hub which is again a SQL Server 2005 database using SQL Service Broker. Data will be sent from the central hub to the distributed sites and vice versa. I need to authenticate the communication and also secure the communication by encrypting the messages. Which security shall I use? Where do I configure the type of security being used? What is the difference between transport security Vs dialogue security - Full security model?

I Really Need A Debate! Type - Attributes Vs Super Type - Sub Types

Apr 22, 2004

I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!

Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:


tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle

tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity

tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150

tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000


Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?


tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks

tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord

tbCars
fkVIN | Doors |

tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000


Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.

Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...

Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.

E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?


tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1

tbCaps
CapID | Vendor | Price | et....


Any thoughts at all? I thought this would have been a pretty damn hot topic!

Connection Type Limitations When Using XML Data Type In SQL Task

Jul 23, 2007

I'm trying to use the SSIS Execute SQL Task to pull XML from a SQL 2005 database table. The SQL is of the following form:




SELECT
(



SELECT
MT.MessageId 'MessageId',
MT.MessageType 'MessageType',
FROM MessageTable MT
ORDER BY MT.messageid desc
FOR XML PATH('MessageStatus'), TYPE


)
FOR XML PATH('Report'), TYPE

For some reason I can only get this query to work if I use an ADO.NET connection type. If I try to use something like the OLEDB connection I get the following error:



<ROOT><?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to SQL Server" Description="No description provided"?></ROOT>



Can anyone tell me why the SELECT ... FOR XML PATH... seems only to work with ADO.NET connections?



Thanks

Walter

CREATE TYPE Failed Because It Could Not Find Type

Hello --

I am having a UDT problem. When I run the Create Type command. I receive the "could not find type" error. I have seen other posts on here related to the default namespace in VB.NET. When I add the namespace I receive "Incorrect syntax near '.'." What is the format of the EXTERNAL NAME parameter. Thanks for any help. Code below...

Incorrect Syntax Error:

DROP ASSEMBLY CadSqlUdtsCREATE ASSEMBLY CadSqlUdtsAUTHORIZATION [dbo]FROM 'E:CAD.NETCADUDTsReleaseCadSqlUdts.dll'WITH PERMISSION_SET = SAFEGOCREATE TYPE dbo.ReportingAreaUDTEXTERNAL NAME CadSqlUdts.[CadSqlUdts.CadSqlUdts].ReportingAreaUDT;GO

Unable To Cast COM Object Of Type 'System.__ComObject' To Class Type 'System.Data.SqlClient.SqlConn

@PARAM1 : Unable To Cast Object Of Type 'System.Data.SqlTypes.SqlInt32 To Type System.IConvertable

Apr 23, 2007

I get the following message in the vs2005 querybuilder when i do a preview:



***********************************
SQL Execution Error.

Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)



Error Source: SQL Server Compact Edition ADO.NET Data Provider


Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************

The same querypreview works fine without the parameter:



SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)



Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

Index Creation Causes Error The Conversion Of A Char Data Type To A Datetime Data Type Resulted...

Jul 23, 2005

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error. Dropping the index solves theproblem.Can anyone tell me why an index would cause a query to fail?Thanks a lot in advance,AmirCREATE TABLE [PTRANS] ([CHL#] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[CHCENT] [numeric](2, 0) NOT NULL ,[CHYYMM] [numeric](4, 0) NOT NULL ,[CHDAY] [numeric](2, 0) NOT NULL ,[CHTC] [char] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE VIEW dbo.vwTransactionsASSELECT CONVERT(datetime, dbo.udf_AddDashes(REPLICATE('0', 2 -LEN(CHCENT)) + CONVERT(varchar, CHCENT) + REPLICATE('0', 4 -LEN(CHYYMM))+ CONVERT(varchar, CHYYMM) + REPLICATE('0', 2 -LEN(CHDAY)) + CONVERT(varchar, CHDAY)), 20) AS TransactionDate,CHL# AS AssetNumber,CHTC AS TransactionCodeFROM dbo.PTRANSWHERE (CHCENT <> 0) AND (CHTC <> 'RA')*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Convert Ntext Type To XML Type

Dec 6, 2007

 I have a ntext column which stores rows of xml data. Ive decided that the best way to query the xml data is to Convert the ntext data into xml data type and use Sql Server 2005 builtin Xml Query tools to perform FLWOR expressions. The problem Im having is getting the ntext data Converted to xml.When I try to convert the ntext text, I of course get an error that local variables of ntext type are invalid.Any suggestions on a way I might accomplish this?Thanks, -lance

A Text-type Value To A Date-type Value

Apr 2, 2008

Hi
Is it possibly in SqlDataSource's SelectCommad to convert a text-type value to a date-type value (11/1/2008 (text) -> 11/1/2008 (date) ) , so that order by can be used. Or is the other ways to use order by correctly with text-type (date)values
Thanks.

Unable To Cast Object Of Type 'System.String' To Type 'System.Web.UI.WebControls.Parameter'.

I'm getting this error on a vb.net page the needs to execute two separate stored procedures.  The first one, is the main insert, and returns the identity value for the ClientID.  The second stored procedure inserts data, but needs to insert the ClientID returned in the first stored procedure.  What am I doing wrong with including the identity value "ClientID" in the second stored procedure?
