How are passwords stored in a database application?
In database applications passwords are usually stored in the database, so storing passwords in the database should be implemented very carefully. It is obvious that storing passwords in the table with plain text is very vulnerable, because if an attacker accesses the database he/she can steal users’ passwords.
What should the default cursor be in Transact-SQL?
If a DECLARE CURSOR using Transact-SQL syntax does not specify READ_ONLY, OPTIMISTIC, or SCROLL_LOCKS, the default is as follows: If the SELECT statement does not support updates (insufficient permissions, accessing remote tables that do not support updates, and so on), the cursor is READ_ONLY. STATIC and FAST_FORWARD cursors default to READ_ONLY.
Is it safe to store passwords in plain text?
It is obvious that storing passwords in the table with plain text is very vulnerable, because if an attacker accesses the database he/she can steal users’ passwords. It is indisputable that passwords in a database should be encrypted and made undecipherable as much as possible. Let’s see how to encrypt and store passwords in a SQL Server database.
How are inserts visible from outside the cursor?
Inserts made outside the cursor (by other processes) are visible only if the cursor is closed and reopened. Inserts made from inside the cursor are visible at the end of the result set. Updates of key values from outside the cursor resemble a delete of the old row followed by an insert of the new row.
Can you use SQL Server Agent service account?
Hence we cannot use SQL Server Agent Service Account. How can we set up the specific user in order to run on the package as it? Simple using credential and proxy. Let’s start.
How to authenticate a password in SQL Server?
Now let’s create a simple procedure to authenticate the user using an encrypted password with the salt: CREATE PROCEDURE dbo.uspLogin @pLoginName NVARCHAR (254), @pPassword NVARCHAR (50), @responseMessage NVARCHAR (250)=” OUTPUT AS BEGIN SET NOCOUNT ON DECLARE @userID INT IF EXISTS (SELECT TOP 1 UserID FROM [dbo].
Can a password be stored in an unsecure way?
But all these considerations are not enough if passwords are stored in an unsecure way. In database applications passwords are usually stored in the database, so storing passwords in the database should be implemented very carefully.
