In the end, there is not way (yet) to get around this problem of package sharing (if there is, I would love to hear it!).

This holds true even when you try and give users dbo access to the MSDB database in a vain attempt to “share” packages with other database users. Meaning that only members of sysadmin can edit and save any package they like, but all other users are restricted only to the packages they initially created themselves. It is important to remember that SQL Servers access model for DTS packages is, well, limited. In part one I briefly mentioned DTS security.

You can use pwdencrypt and pwdcompare yourself (unsupported of course) for password management.

You can hack passwords by re-creating the sp_addlogin routine and adding code to record the password before its encrypted.What this is exactly I am not sure so I cannot comment on its robustness (see WITH ENCRYPTION section below). Funny enough, the sp_addlogin routine and many other master stored procedures are not encrypted, and you will see that SQL Server uses a pwdencrypt routine to do the encryption. Programmers and DBA’s should leave it as default where possible. This does not mean your application programmers will be using it. The text has been replaced with this comment for security reasons.īy default, sp_addlogin has the ' encryption_option ' option set to NULL (ie. When tracing SQL Server via Profiler, you will notice sp_addlogin commands are not included with the following: - 'sp_addlogin'was found in the text of this event. ensure password “resetting” is properly managed in terms of.try not to modify the internal SQL Server sp_ procedures for login creation. It can mean problems when service packs are applied, and difficult to properly maintain without affecting the overall integrity of the DBMS.if you are using active directory, revise password creation and expiration with the system administrator, ensure the application developers look for expiration times in their code.

consider utilising Active Directory and Windows authentication for end-user access to your web-site code, then uses embedded logic within COM+ to connect to SQL Server (see later).

consider how password expiration will work.

ensure application logic forces these minimum requirements.

Ask around, many companies have security administrators and one thing they are always on top of is password structure and expiration.

The “blank” password problem does not stop at the SA account, the DBA should be very strict in mixed mode security environments and force well structured form and length requirements for passwords.

The SA account should always have a password set if Windows Authentication is not being used as the primary means of connecting to gain sysadmin privileges. Password management and “blank” passwords If you alter the BUILTIN/Administrator login and revoke sysadmin, remember that this adversely affects the SQL Agent database connection that must be altered accordingly. In the BOL, it clearly highlights the fact that the SQL Agent server connection must have sysadmin access. Jobs will simply not start and their “next run date” will be “unknown”.

Funny enough, you will see no errors in the SQL Server log or SQL Agent log in relation to this. As such, altering the BUILTIN/Administrators account and revoking sysadmin access will prevent the service from running jobs. By default, the service will be started via the local system account and its SQL Server connection via “windows authentication”. This is to do with the default set up of the SQL Agent service account. I came across a problem the other day in relation to altering the BUILTIN/Administrators account (as discussed in Part 1) that was not mentioned.
