How To Secure Mdf

Sep 24, 2005

I am designing an application built on sql server 2000
how can I prohibit other sql server users from accessing my database and allowing only acceesing it through my application or through owner designer of sql server database.

my situation needs sometimes copying the db from the end user platforms to
my designer computer to analyze some problems or maintainenace or modification, and also I have no control on users windows environment and I need the end user professional not to enter the my db from outside my application.

So,
is there anything I can do to secure an MDF (MSDE/SQL Server 2000) file so that a user cannot see my schema under any circumstances.

Even if I lock the MDF down and secure the instance, a smart user can just shut off the SQL server, copy the MDF to another instance, sp_attachdb and open it with sa rights. I need a way to prevent others from getting inside my schema.

How Secure Is Sql Ce Password?

Mar 5, 2008

I have developed an application that uses a SQL Server compact edition database (.sdf). The database contains important data that I do not wish people to access.

My question is if I choose to Encrypt the database using the option available when you create the database and specify a password how secure is it ?

Are there tools on the market that will be able to crack this password and therefore gain access ?

Thanks

How To Secure The Database

Jul 10, 2007

Hello...



I develop a .NET Application which uses a SQL Express Database. The application will be distributet to several customers. That means the customer must have (or install) SQL Server Express Edition .

But we dont want that the users manual access to the database.

As far as understand that is not possible because the user (customer) will be the administrator for the SQL Server Express because it runs in his own PC (no password security).

Am I right? Thank you..

Possible To Secure Using .Net StrongNameIdentityPermission?

Oct 24, 2006

Is it possible to secure a SQL Server database or schema using a technique such as the .Net StrongNameIdentityPermission attribute? The intent is that SQL Server would only permit transactions coming from assemblies which were signed with a particular .Net StrongName private key.

We are installing a 3rd party SQL Server / ASP.Net application which must run in our DMZ and we are looking for all possible measures to secure the SQL Server database.

Thanks

My intention is to restrict access to my databases only to certain users (may be SQL Logins)



Please guide me how to accomplish this...

Are Packets From .NET To SQL Server Secure?

Feb 20, 2004

When I'm getting data from sqlserver using ado.net and a sqldataadapter, are the resultant network traffic packets secure? If I wanted to deploy my objects at a remote site, would I still be safe going straight to my sql server from there or should I build a web service and then auto generate 'remote' versions of my objects that will then communicate to the web service on https?

thanks

Enterprise Manager - How Secure Is It?

Oct 30, 2004

I connect to my clients SQL databases via Enterprise Manager. Most of the time the SQL server resides at a web host. A colleague recently told me that this is a huge security hole and I should be using Remote Desktop instead.

I would appreciate other input, opinions, and guidance on this issue.

Mabey some sort of SSH software that is desinged for this? I have attempted to use VPN however this is not for a network, just 2 servers, no domain controller or DHCP server is available, they are connected directly to the internet.

Any ideas would be appreciated.

Is General Authentication Secure Enough?

Feb 5, 2008



Hello,
I have a project which I am working on that includes database support. The Database server has several databases hosted on it. Setting network security hardware/software aside for a moment and strictly talking about security handled by the Database server, is is good enough to rely on adding users to a databases "users" list or are there other things on the database server I should look at? We are using both Windows and SQL authentication. We have some users that are to have access to all the databases (Administrators and database operators) and some who will only be permitted to have access to a few of the databases (not all of them). Obviously there are other security concerns such as network firewalls and the such which are being handled by the IT team but I wanted to know if the simple 'add user to "users" list and remove for the rest' approach is all that can be done or if there is more that can be done on the SQL server.

Thanks!

Row Level Filtering (does Not Need To Be Secure)

May 11, 2007

I'm trying to design a system where I can filter (not secure) a users results, the user may or may not pass in a user ID. We typically use middle tier connection pooling with a single identity, so I believe labelling is not suitable.



I think the ideal solution would be...



User to establishes a connection through our application, a user id will be established as part of the connection.
A view is created describing what the user is able to access. Preferably the user should not be aware of the view.
The user or our application executes a number of select queries.

Note that there may be many users with different filters required connecting at any time.



Direct user updates of the table do not need to be supported.

Secure .NET 1.1 Application From Users

Jan 20, 2006

Hi all.

I am developing an distributed VB.NET 1.1 application with a TripleDES capable socket layer for communication with my server app.

I need to secure the distributed app from the users within the organization I am developing it for (a franchise).

I do not wish to store any encryption keys in the source code as these would be obvious to any seasoned hacker through decompilation of my binaries (even with obfuscation). I have decided to use the windows DPAPI (under machine storage mode) to secure manually entered (at installation) encryption layer keys in the registry. The salt values for this DPAPI mode also need to be secured, as a disgruntled franchise owner may be the hacker (and hence would have admin privilege on the machine the software is installed on). Not as far fetched as you think !

This is the beginning of a vicious cycle. How do I secure and where do I store this salt value safely ? With it a hacker with admin privilige can easily decrypt my keys if they know I am using machine mode DPAPI. Can I use ACLs to protect the keys with an account I set up manually on the machine ? If so then I would need to be able to switch account identities in my code (which I haven't researched as yet) and then would need to store the password to that somewhere.

If anyone could offer any insight or direction it would be much appreciated.

Secure Access To Database

Nov 1, 2006

Hello Experts!!

Let me start off by saying I'm not a SQL expert and have very limited knowledge on the topic.Here is my question:Our organization has an archiving solution that stores data in a SQL database. This applicaton creates two SQL accounts. One that is used to archive to the database. The second to browse the database from a search interface provided by the application. With all the federal compliance issues I see that they require the data to be stored in "a non-rewriteable and non-erasable format". My question is. How can I prevent the database from being erased in the SQL database? As 'Administrator' I can open Enterprise Manager and open a table in the database and simply delete any record that I wish. I understand that might have this ability because I'm logged on as Administrator. How do I prevent access to this database and prevent access modify the records. I believe the only two accounts that should have access to the database are the Archive and Browse accounts required by the application.

Secure Parts Of A Table

Sep 30, 2007

This is the thread
http://msdn2.microsoft.com/en-us/library/ms998292.aspx

Here it mentions the following
Deployment Considerations
When using Windows authentication to connect to SQL Server in production
environments, consider the following:

Use a custom service account.
Create a SQL Server login for a Windows group.
Assign database permissions to a database role.
Use a Custom Service Account

This is my problem we are trying to convert all our web pages to use Windows Authenication.
DOMAINWEBGROUP (for example).

Tracey and Jack part of this group
But sometimes there may be anothers added to this say John

The security comes from SQL right now i give data reader to the database.

Example
1. ASP.NET uses the service account DOMAINWEBGROUP
2. Assign WEBGROUP to database PERSONEL
Table Employees
Salary
Web Page
Lets say Tracey logs into the web page.....and i have two pages
1. Employess
2. Salary

As the WEBGROUP is data reader viola Tracey sees all salary information.
Im trying to figure out that only Tracey can see Employees

But im not seeing the relationship when using WEBGROUP

Is there a way in SQL to say yes we have the DOMAINWEBGROUP
but in sql also put in Tracey and know that Tracey is part of DOMAINWEBGROUP
So that in my tables i can only give tracey part of this employee table (say the first name last name) and not salary information. (I know how to use the roles).

The part im confused about is the mapping WEBGROUP to tracey in sql as the web developers only pass in WEBGROUP

How (un)secure Is My Remote SQL Server?

Apr 10, 2007

I've been provided with a server at a hosting company. The server is running W2K3 SP2 in its own workgroup (i.e., non-AD) configuration, but is not behind any type of hardware firewall; there is no VPN in place, either. I connect to the server via RDP using an extremely long and complex password. I'm using the newest version of the RDP client. The article "Hacking RDP" and the ensuing reader comments (http://mcpmag.com/columns/article.asp?EditorialsID=1699) indicate that using RDP in this fashion is relatively safe.



I installed SQL Server 2005 SP2 on this server. I set server authentication to 'SQL Server and Windows Authentication mode'. I created one obscure SQL Server login, using another extremely long and complex password. I also disabled the login for the 'sa' account.



Since installing SQL Server on this server, I've noticed thousands of Failure Audit events in the server's Application log:




Source: MSSQLSERVER

Description: Login failed for user X



where X equals 'administrator', 'root', 'server', 'database' 'sql', 'sa', etc.

These failure events occur almost non-stop, about a dozen per second, and come from a small pool of unknown IP addresses. The IP address seems to change every few hours. I'm guessing that someone is hoping that one of these names is an actual SQL Server login and is trying a brute-force attack to try to stumble upon a matching password. None of these logins are valid, but it's still disconcerting. Is this anything to be concerned about? I could have the hosting company block the IP addresses, but that seems like a losing battle.



Lastly, I used the Surface Area Configuration tool to allow local and remote connections, using TCP/IP only--so that I could begin interacting with this SQL Server from my PC, using both SQL Server Management Studio and my own Visual Studio code. For each method, I'm using the obscure SQL Server login that I created earlier--the one with the extremely long and complex password. How (un)secure is my traffic to/from this SQL Server? I don't believe that my credentials are encrypted, but I'm not sure how much of a risk this is nor do I know how else to more securely connect to SQL Server.



Given these circumstances, is there any way to make this resource more secure? Thanks!

Secure/selective Data Access

Jul 23, 2005

Dear netters,We are looking to build a SQL Server database that will be hooked up toa Web server (WebLogic or a .NET).The database will house data for multiple customers, and therequirement is to have no customer see other customer data. Web serverwill be responsible for authenticating users (ids and passwords will bemaintained there/possibly stored in the database, but will not beactual database logins) -- and establishing pooled connections to thedatabase, using some sort of a proxy login.Ideally, we do not want to have the database itself visible to "theworld", it should reside behind a firewall, and be accessible throughthe Web server, which will do all authentication and routing.We want to have either tables or views defined in such a way that:1. Users can only see their own data and NEVER can see anybody else's.2. Users' access to the database is logged (this includes updates aswell as queries).3. We would like to provide some sort of a reporting mechanism -- whereusers can form their own queries. So, something like a Crystal or anAccess front end, that users are typically familiar with... The problemis that this requires users having direct access to the database (?),and opens up tables (unless, there is a way to create parameterizedviews that will always restrict access to a subset of records).Any advice on how to best implement this is greatly appreciated.Thank you in advance!

Secure Database Files For Sp_attach_db

Oct 29, 2007



hi,

My problem is, I am going to ship MSDE with our product. Now the problem is that if some one copies the .MDF and .LDF files and uses "sp_attach_db" to attach the db files to his own server then my database will be exposed to him. I have tried this and it gets exosed. I cant deploy NT Authentication for the database, bcoz if the end user installes Enterprise manager then my database will be exposed to him. Is there any way that i can sequre the LDF and MDF files of my database so that no one can use that with sp_attach_db? I m using MSDE(Sql server 2000).

DB Engine :: Secure Deletion Of Data

Nov 16, 2015

We have been asked whether it is possible to completely delete sensitive data. When data is deleted it is not actually completely removed from the database but is marked as deleted. It is possible to zero out that data using sp_clean_db_free_space but this doesn't affect the transaction log.

We had hoped that CHECKPOINT would clear the data from the log but we are not completely certain of this. So the question becomes is there a built-in command or function in SQL Server 2008, or subsequent versions, that will completely remove deleted data, both from the transaction log and the database itself? Or is there a 3rd party tool to accomplish the same thing?

Is 'NT AuthorityNetwork Service' Login Secure?

May 23, 2008

Our SQL Server 2005 db has an NT AuthorityNetwork Service login with public access. It is used from web services hosted by IIS 6.0 located on another server on the same network. So does this mean that any Windows Server 2003 box on our network has public access to the database? What about servers off of our network? Is there a way to limit this account to just a single server on our network?

Thank you.

Mark
