Usability Vs. Injection Protection
Nov 30, 2007
I have a question that I am sure that others have had to deal with in the past. I am writing business requirements for a web application that stores names, addresses, etc. I have hit a bit of a problem in design with allowing users to enter data they need, like the name O'Brien, and developers saying that allowing the single quote in a field could allow for an injection attack.
Developers want to strip out single quotes when they occur in the data, however the users are insistent that names and addresses that have single quotes in them are shown properly.
Is there any middle ground so that the system can be built to avoid an injection, but still allow data to be entered as intended.

Alright, so I have a basic search function to look through a field in my database which is decided by a query string. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseConnectionString %>"
SelectCommand="SELECT * FROM [Employee] WHERE ([Responsibilities] LIKE '%' + @Responsibilities + '%')"> <SelectParameters> <asp:QueryStringParameter Name="Responsibilities" QueryStringField="q" Type="String" /> </SelectParameters> </asp:SqlDataSource> But, I'd really like to fix it using parameterized SQL queries, so that people aren't dropping my tables. >_>I've been lookin' around for some code on how to do this in C#.NET, and most of them seem to look like this: SqlConnection objConnection = new SqlConnection(_ConnectionString);objConnection.Open();SqlCommand objCommand = new SqlCommand( "SELECT * FROM User WHERE Name = @Name AND Password = @Password", objConnection);objCommand.Parameters.Add("@Name", NameTextBox.Text);objCommand.Parameters.Add("@Password", PasswordTextBox.Text);SqlDataReader objReader = objCommand.ExecuteReader(); My problem is that I don't know how really know how to go from my code to this code... I mean, would I throw the latter in my backend code and call what it returns as a string, would I entirely replace my Datasource and do soemthin' with the code? Any help, in the form of tutorials or just straight up tellin' me here, would be greatly appreciated.Thanks. =D

I have been using SSRS2k5 now since early CTP, and one thing that bothers me is the lack of keyboard shortcuts and windows standards.
For example: If I am in the data screen, and want to enter a SQL Query, I cannot use the tab key. So I copy it to SQL Management Studio, but I cant use CTRL-A to select all.
If I am in the layout tab, and want to bold a field, I hit CTRL-B, but that pulls up the breakpoint entry dialog.
If I have a table on a report, and want to add click-thru navigation, I have to:
Right click on cell 1
Click on properties
Select Navigation
Click on Jump to Report
Select the report from the list
Click on parameters
Select parameter 1
Now, if I want a field as the parameter, i can just select from the drop down, but most of the time I am passing parameters from the 1st report to the 2nd report. Then i have to:
Click on the Expression button
Either type the parameter name, or click on it from the list.
Press OK
Repeat number 8 for the number of parameters.
Hit OK.
Hit OK.
REPEAT FOR ALL CELLS
Now, here is the issue... If you have a 20 column table, and have similar click thru functionality, you have to repeat this process for each cell. You cannot multi select. THAT would be a huge timesaver. I would rather set all 20 cells the same, and tweak 1 or 2, rather than kill my wrist mousing thru the above process 20 times. (It hurts, trust me )
These seem like little things, until you are working on 50 reports in a short time frame.
Anyone else find this bothersome?
Is there any improvement on the GUI in the next release?
Thanks!

Laws and Myths of Usability & Interface Design
Introduction
Usability and relevance have been identified as the major factors preventing mass adoption of
Business Intelligence applications. What we have today are traditional BI tools that don't work
nearly as well as they should, even for analysts and power users. The reason they haven't
reached the masses is because most of the tools are so difficult to use and reveal so little
about the data that only power users are willing to put up with them. Just as Google redefined
the web by making search and therefore access easy … the same needs to occur with the BI
suite.
Overwhelmingly, traditional BI products are designed for the technology expert. The perceived functionality requirements are driven by widget wish lists
rather than actual business user (the BI consumers) needs.
Our design philosophy has been honed through experience and results in a simple equation:
Usability = Simplicity + Unity
This paper is a reflection on some of the design approaches used in the development of
Yellowfin. Its purpose is to provide an insight into what makes web based applications ‘work’
and how Yellowfin will continue to evolve and improve. The principles are defined by 5 laws
and 5 myths.
The laws:
1. Simplicity – the art of Zen and interface design
2. Strive for internal and external unity
3. Innovation stretchs engineering capability
4. Everything changes except change itself
5. First impressions count
The Myths:
1. Form follows function
2. Only users know what they want
3. Involve many people in your design process
4. Usability testing will ensure a great UI
5. You can’t live without rigorous design processes
At Yellowfin we use the principles outlined in this paper to continue to deliver innovation,
improvements and what we hope is an exceptional software experience for our customers.
#1 Simplicity – the art of Zen and interface design
Users want simplicity! They want to do the job they need to do with the minimum of effort and
complexity. Users must be able to perform their most frequent, most important tasks without
any resistance. This means:
1. not having to spend time sifting through an array of irrelevant options, and
2. not having to browse help files or a manual to accomplish simple tasks
The goal, then, is obvious: to maximize performance while minimizing confusion. But as
vendors and users are discovering, that's no small trick. Simplicity is sometimes the least
simple thing to achieve." 1
Simplicity requires that your code does all the hard work, rather than the user. Google, as an
example, maintains the simplest of search interfaces. No distractions from blogs, news or
ads, you simply type in your query and go. Behind this simplicity is up to 500,000 computers
globally linked and participating in answering your query. In essence, one of the most
complex hardware/software systems on the planet is hidden behind a very simple webpage
that is virtually 100% whitespace.
Deliver the right level of blatant functionality to suit user skills
The most common UI issue in report writers is BOS (Button Overuse Syndrome). If there is a
formatting option, or any option for that matter, then traditionally it needs a button. How
wrong can you be! BOS delivers too many options and results in a user confused by choice.
The cure for BOS is UI simplification through minimalism – the art of Zen and interface
design. Focus on what users do 90% of the time. Chances are your users will not mind using
a drop down menu or popup forms if the action they are performing is not regularly repeated.
Provide buttons for those actions that are regularly used and then drop down menus or side
panel menus for all the others. Whatever you do, keep the interface simple and consistent.
Of course the level of competence of your user will influence your design decisions. An
example of a product that is tailored for user sophistication is the video camera. Consumer
versions have lots of functionality but hidden in layers of menus, whilst professional versions
tend to be button centric to allow rapid access to all the functions desired.
Taking this lesson into account we have designed the UI specifically to suit the technical
ability of the average user. The interface is made more flexible through role based access,
where greater control is exposed as technical proficiency increases. For example the report
writer (a business user function is menu driven) but the more technical metadata layer is
panel and options driven.
Simplicity in everything you do

I'm trying to protect a package... using an owner password.
After I create an owner password and generate a dts command line from
DTSRunUI... it puts the package password in the string.
Basically if someone goes into the job and looks at this line they have the password to open the package...
DTSRun /S "svr-eqanalysis" /N "OrgExtract Rename" /M "password" /G "{2E2B6F07-0E56-4212-A894-B85A4EAA6C8C}" /W "0" /E
We can not remove the builtin administrators group from the machine
therefore system admins that want to poke around into our work can do so....
any suggestions......
thanks,

Hello all,
I'm using the following code to query my database...
public static void InsertsComments(string Comments, string TagID, string UserName) { SqlCommand cmd = new SqlCommand("insert into TG_UserComments (Comments, Tag_ID, UserName) values (@Comments, @TagID, @UserName)", conn); conn.Open(); cmd.Parameters.Add(new SqlParameter("@Comments", Comments)); cmd.Parameters.Add(new SqlParameter("@TagID", TagID)); cmd.Parameters.Add(new SqlParameter("@UserName", UserName)); cmd.ExecuteNonQuery(); conn.Close();
}
My first question is, should I be making @Comments, @TagID, @UserName a little more cryptic? Liks @CommDBQ23 or something? Does that make it safer?
Also, I'm going to use stored procs query the database, instead of how I'm doing it above. What would I need to change in the code to do this? Obviously I'd need to call a stored proc on the server, but can I still protect myself from sql injections with the above code? Is there anything else I should be doing to secure my application at this level?
Thanks!

Hi all,
I've developed a database driven web app in ASP.NET and ready to deploy to my customer. However, I'd like to know is there any way to encrypt / protect the source of my stored procedure and view in SQL Server? My web app make heavily use of SPROCs and DB Views and I don't want my client to view / alter it, compared with the web app, I can compile it into a .DLL file and remove all business logic, any similar thing in SQL world?
Thanks,

I'm having problems with ftp tasks in SSIS packages where protectionlevel=EncryptSensativeWithPassword. I've used this many times with no problems, but now that I've upgraded to 2005 SP2, It's not working as before.
I have a functioning SSIS package with an FTP download. It works fine on my workstation in the developement environment.
If I load it to the SQL server using Server Manager Studio under my account, I cannot run the package from the server when logged on as Administrator, nor can I schedule it to run under the SQLAgent account as a job. The error mesages are: Unable to connect to FTP server using "FTP Connection Manager" and "The password was not allowed". Obviously the password being sent to the ftp server is wrong, but it was right under developement. Further more, If I log into the server under my account the package runs fine!
If I load the package while logged in as administrator, I can only run the package as administrator. And of course, if I load the package as SQLagent, I can only run the package as SQLagent.
This is not how SSIS packages were operating before I upgraded! In fact I've reloaded some existing packages and found that they now have inherited this behavior (after they have been re-imported)
It looks to me like SSIS is using the EncryptSensativeWithUserKey option, instead of the EncryptSensativeWithPassword option. I'm not sure how to confirm this, short of using a packet sniffer to watch the ftp traffic.
I could switch to PackageConfigurations, but I was happy with the EncryptSensativeWithPassword option, which seemed appropriate for our operation.
Does anyone have any ideas what could be going on, or any suggestions to troubleshoot this? How can I tell if password is encrypted or not?

Hi All,
I would like to build a standard BI solution based on MS SQL2008 - integration services, analysis service and reoprting services.
This stardard BI solution can be distributed to multi customers - however I want to protect the source code so customers cant access the code.
I would like to be able to ecrypt or protect the solution - so the customer only get the "executable" but they cant access the soruce code. This is to protect my intellectual property.
Kindly advise if there are any way to achive this objective in SQL2008.
I did some research in SQL 2005 long time back - but I was unable to find resolution to protect the intellectual property.
I would be extremely pleased to get some good advise on how to protect IP in SQL 2008.
Thanks heaps, Thomas

Hello everyone,
Can someone recommend me the most efficient protection level for SSIS
packages for my environment? I've been doing some reading on this lately, but can't really decide which one to use. The Rely on server storage for encryption (ServerStorage) seems interesting, but I'm unsure if that would work on my environment (Windows Authentication).
Currently I'm saving my packages to my dev server under "Encrypt sensitive data with user key" Protection level, but seems like the passwords for the FTP Connection for instance doesn't get saved when I deploy my package to the server.
Our environment consists of 2 dev servers + 2 prod servers with windows authentication, our SQL Agent Account is a domain account with local admin rights and sysadmin rights on the SQL Server and we try to use proxy accounts to access network resources instead of giving the agent access to everything.
This is what I found on MS's web site.

All:
I am aware that I am raising an issue/question that has quite a number of ancestors in this forum. In reviewing some of the threads I still believe my situation has a bit of a twist; but that could just be me.
The process I used until a change I made recently worked just fine. A handful of my packages connect to our ERP system that only supports an ODBC connection. I set the Protection Level to the default, and then deploy the packages to the server. I use an agent to run the jobs that include these packages as steps. I have hardcoded the userID and password in the SQL jobs and so they have run fine.
In an effort to reduce maintenance on the packages I decided to run the packages from the File System instead of deploying them to the server. Now, the packages are not running as I have not changes the Protection Level yet. I did test running one of the packages using a Proxy I have created but that does not work either.
Based upon what I have read it appears that the first thing I need to do is change the Protection Level to DoNotSaveSensitive. How do I then pass the ID and password to the agent?
a. Create a confirguation file?
b. Create a package template?
c. Both of the above
To reiterate I do not wish to deploy the packages to the server; I prefer to run the packages from the File System. Further, I just have one box on which everything happens; there are no migration issues across servers.
Some insights from this group will be greatly appreciated.
Thank you!

Hello,
I have a package that contains a connection manager to a DB2 source. The password is configured within the connection mananger. The configuration string was included in the package configurations (SQL Server). The package is saved in VSS, and locally on my hard drive.
When a colleague attempts to open the package is Visual Studio (from VSS), He gets a message similar to the following.
Error 1 Error loading 'Geac_RK502.dtsx' : Failed to remove package protection with error 0x8009000B "Key not valid for use in specified state.". This occurs in the CPackage::LoadFromXML method. . C:Documents and SettingscdunnMy DocumentsVisual Studio 2005ProjectsGeac_RK502Geac_RK502Geac_RK502.dtsx 1 1
I'm very sure the package protection level was to encrypt sensitive data with user key. After he ran into this problem, I tried again to open the package from my computer (the machine that the package was created on) and now I get the same message. If I attempt to open the package anyway, I first get a message that there were errors in the package while it was being loaded, and that the package might be corrupt. After that message, I get one that states the document contains one or more extremely long lines of text....do you still want to open the file. If I click yes, the package opens read only with the following message:
Microsoft Visual Studio is unable to load this document. Failed to remove package protection with error 0x80090008. "Key not valid for use in specified state". This occurs iin the CPackage:LoadFromXML method.
I'm looking into more information about package protection. What can I do to avoid this problem, and what protection level should I be using so that my colleague can open the package? How can I correct the problem with this particular package, and have the package open?
Thank you for your help!

Hi all,
I have a problem while trying to deploy my packages that are configured in ProtectionLevel=EncryptSensitiveWithUserPassword
I use the Deployment Utility to deploy my packages. I set the password when deploying and the deplyment works fine. But I run the packages I have the following error : " Failed to decrypt an encrypted XML node because the password was not specified or not correct."
Did I miss something ?

Howdy!
Couple quick questions:
1) How much does setting encryption cost in terms of speed of querying and cpu usage?
2) If encryption is not set, is the password "encrypted" when its sent with the initialization routine?
Thanks in advance!

For those of you who have had a hard time like me trying to figure out using Protection level for an SSIS package whilst deploying the package via the SQL Server Agent, here is a piece of advice:
Firstly the protection level is set by Default to - "EncryptSensitivewithUserKey".
The encryption actually takes place only if you have things like - passwords etc..
From my experience - using both - "EncryptSensitivewithUserKey" and "EncryptSensitivewithPassword" Security features have turned out to be unreliable when deploying through SQL Server Agent (even while using a Proxy account having all previliges).
This is it seems because of issues with the user who created the package being different from the user who deployed the package. (which is really ridiculous).
So I used the ProtectionLevel - "DontSaveSensitive" - which means it is not going to encrypt anything in the package and so ur sensitive information would be blank. You would have to then supply your password etc using a configuration XML file. - using SSIS "Package configuation" in your menu....
This has been the most reliable way of solving the whole problem with encryption.
bear in mind that you might want to put the XML file in a secure location to which no one else has access to.
Thanks

I am currently designing a SSIS package that will migrate data from Syabse to Sql server. If these packages are to be deployed to file system (as this is one time run for migrating data) or to SSIS catalog or to Sql server.
Also, I have not changed the default protection level value in packages during design time and would like to know if I have to change it while handling the deployment using DTutil (yes, i need to deploy & execute using command line utilities).
Please note that I do not have access to PROD, UAT environments and deployment team will use my BAT file that is expected to deploy and execute the packages.

Hi,
Can anyone explain to me why my ssis packages will not work when DontSaveSensitive protection level is selected? My package configurations are set as SQL server configuration type, and I have a table in a database that contains all the sensitive information (passwords and such). If I select "EncryptSensitiveWithUserKey" everything works, but I will be the only one able to execute the packages (not good, I need others to be able to execute them as well).
The error I'm getting tells me that the connection is not configured correctly or I may not have the right permissions on the connection.
My guess is that the DontSaveSensitive drops the passwords, but when I edit the data source and re-enter the password, it still does not work. Also, the database table I use that contains the sensitive data is not affected, all data remains.
What the fudge is going on here? I'm a newbie at this, can someone help me out?

http://msdn2.microsoft.com/en-us/library/ms172391.aspx
But there is a problem with creating SyncStatus class object. I can't get into it and I can't create. maybe some reference will help? (I use reference to SQLServerCE). This error stoped my work for now, so I am waiting for some answers.
And if it's simple resolution for this problem - sorry. I just started programming applications for Mobile Devices.

Our SSIS packages use the Web Service Task to call services to send email and write package failure data to a department wide database. These Web Service Calls are failing with HTTP 401 errors. It was caused by the passwords for the HTTP connections not being saved when the SSIS pkgs were saved to .dtsx files. I have tried saving the package with a password and the EncryptSensitiveWithPassword protection option. This password can be supplied when the package is called from another package or a package is executed in Visual Studio but cannot be supplied to DTexec to execute the package in a job. DTexec does have a /Password parameter but it is rejected if the package is loaded from a .dtsx file.
This appears to be a bug in DTexec. It only accepts the /Password parameter when the package is loaded with the /SQL option. Specifying /Password and /File is not supported.
Is this a known bug? Are there any workarounds?
Has anyone successfully called a Web Service from SSIS executed via DTexec?

Dim objCmd As New SqlCommand("SELECT * FROM mytable where id ='" & Request.QueryString("id") & '" , objConn)As it's best to use stored proceduresIs there any other problems you guys might have had happen to you or other possibilites for attackers that I should know about? Cheers

I manage a VBSript/ASP/IIS/SQL website for a nonprofit, and our website has been hacked by SQL injections. I have changed the code on the website so it can't access the database, cleaned the database, backed up the database, but now need to find a way to tighten up the security so it won't happen again.
We're a non-profit- so the server is Windows 2000 Terminal SP4 (yeah, I know, it's old, bear with me).
I was using the following code to access the database from the website:
dbconn.open "DSN=cptigers;UID=sqlwebaccess;Password=password" (where cptigers is the name of the DSN connection with SQL server authentication).
So far, I've removed read permission in IIS on the include file that I use to open the database. I've changed the data source to use Windows NT authentication, and set the SQL login MDBCA/cptigers (this is the IIS login) to have public and db_denydatawriter roles.
But I'm not sure how to call this database connection in the code (how do you define the IIS user and password?), and not sure if this is sufficient to protect from future SQL injections.
Am I heading the right direction? Thanks, Amanda

Does anyone have any insight regarding SQL injection involving a table name t_jiaozhu? Is this a new hack script or old? I am having a hard time finding any clear details other than ways to stop injection from happening. This I know, what I am trying to figure out is what damaged may have been caused (worse case) and what would be a good plan of attack to figure out what steps suceeded/failed.
