SQL Server 2000 Security - Part 6 - Ownership and Object Permissions

  • Article

We have described, so far, authorization based on a predefined fixed server (determining a set of SQL server-wide privileges) and database (applying to database objects and activities) roles. We have also discussed application roles, which makes the level of permissions independent of those assigned to a SQL Server login or a database user account. Now it is time to look into permissions from the point of view of database objects. There are two main factors that play a role in determining how access rights to them are evaluated - their ownership and custom permissions. We will discuss the first one of these topics in this article and will continue with the other one in the next installment of this series.

SQL Server 2005 Security - Part 3 Encryption

  • Article

After discussing authentication and authorization behavior of SQL Server 2005 Beta 2 in the previous two articles of this series, it is time to look into other security-related changes. In particular, we will focus on the freshly introduced native database encryption capabilities. While some encryption functionality existed in the previous versions (e.g. involving column encryption APIs within User Defined Functions or PWDENCRYPT password one-way hash function), it was relatively limited and rarely used. SQL Server 2005 provides significant improvements in this area.

SQL Server 2005 Security - Part 2 Authorization

  • Article

Following the discussion of new or enhanced authentication-related functionality in SQL Server 2005 Beta 2 in our previous article, we are shifting our focus to authorization features, which determine the level of access rights once the user's logon process is successfully completed. Among topics that will be covered here, are separation of user and schema, modifiable context of module execution, increased permission granularity, and improved catalog security.

The Case of the Stolen Laptop: Mitigating the Threats of Equipment The

  • Article

The fear of having laptops stolen is a huge worry for all organizations. Maybe it’s even happened to you (I hope not!). The solution is simple, really -- don’t let your laptop get stolen. (I can hear you laughing now.) Keep the thing with you at all times, or leave it in your hotel room when you don’t want to carry it around. Yes, everyone has heard the warnings about hotel room theft, but I’ve never had something stolen from a hotel room and I spend well over 200 nights a year in hotels. (If you travel to a location where the general population has kleptomaniac tendencies, stay in hotels that offer safes in the room.) You’re far more likely to leave your laptop or PDA or smart phone or USB drive lying on the seat in a taxi or on the counter at a bar.

Question of the Day

Fun with JSON I

I have some data in a table: 

CREATE TABLE #test_data
(
    id INT PRIMARY KEY,
    name VARCHAR(100),
    birth_date DATE
);

-- Step 2: Insert rows  
INSERT INTO #test_data
VALUES
(1, 'Olivia', '2025-01-05'),
(2, 'Emma', '2025-03-02'),
(3, 'Liam', '2025-11-15'),
(4, 'Noah', '2025-12-22');
If I run this query, how many rows are returned? 
SELECT *
FROM OPENJSON(
     (
         SELECT t.* FROM #test_data AS t FOR JSON PATH
     )
             ) t;
