SQL Server grants a security structure. It helps database admins and developers create secure apps and counter threats. A SQL Server instance includes a collection of entities, starting with the server. Every server has several databases. Each database has a mix of securable objects. The SQL Server security framework controls access to entities. It does this via authentication and authorization. The authentication stage involves logging on to SQL Server. A principal requests access by inputting credentials. The server then evaluates them. Authentication verifies the identification of the user. The authorization shows which securable resources a principal can access. It also shows the allowed operations for those resources.

SQL Server Security Threats

Affect SQL Server Databases 3 Common Threats

SQL Server authentication: SQL Server logins can be vulnerable to attacks. These attacks can use connection string injection. At runtime, the program constructs a connection string. If it’s not checked for valid keyword pairs, an attacker can add extra characters. These can perform unauthorized actions on the server. The more secure alternative of using Windows authentication is preferable.

Privilege escalation: SQL Server databases hold sensitive data. Users may gain unauthorized access by assuming the privileges of more trusted roles. To mitigate this, run users as least-privileged accounts. Block code execution from admin or owner accounts. Use certificates to sign stored procedures if additional permissions need to be granted. Or, use impersonation, but only for the task’s duration.

SQL injection: Like other databases, SQL Server is subject to security breaches. SQL queries can have malicious users put code into them. Data leaks, illegal access, and other security problems may result from this. Use stored procedures, input validation, and parameterized queries to stop SQL injection. To fix any known vulnerabilities, upgrade SQL Server on a regular basis.

A common problem is how to manage SQL Server security with SQL Source Control. With the help of this post, you will get to know this. To manage SQL Server security with SQL Source Control, follow the 3 steps below:

First step: Migrate from users to database roles

With the help of the database, you can authorize permissions without considering users. Thus, users will be joined to the role of the database, without affecting any changeset. A database role is a collection of users, as a domain group on the domain controller.

Second step: Ignore the users

You can change the general options of SQL Source on the “setup” tab. You need to check the “Ignore users and role membership.” The users will not be shown anymore. But, you can also add the user manually to the database.

Third step: Filter out the new users

SQL Source Control also enables us to use filters on the objects of the database. For this, you need to make a right-click on the “Other SQL Source Control tasks” on a database, and then select the “Edit filter rules.” A view with the following options will pop up in front of you:

• New DataBase

• New Query

• Script Database as

• Task

• Schema Compare/Deploy

• Data Compare/Deploy

• Tab Color (Database)

• Find Invalid Objects

• Run Tests

• New Tests

• Commit Changes to Source Control

• Get Latest Changes from Source Control

• Open Working Folder

• Open Command Prompt

• Set Up Object Locking

• Other SQL Source Control Tasks

• Policies

• Facets

• Start PowerShell

Column-level protection

Data protection at the column level is frequently required by organizations. SQL Server databases often store sensitive data. This includes customer, employee, and trade secret information. It also includes product and healthcare data.

Sensitive columns often include:

– identification/social security numbers
– mobile phone numbers
– first and family names
– financial account IDs
– any other personal data

This section’s methods and features improve column-level protection. They do so with minimal overhead and without major changes to app code.

To encrypt data at rest and over the wire, use Always Encrypted. Only client libraries acting as application clients can decrypt encrypted data. Use randomized encryption over deterministic where possible. Always Encrypted with secure enclaves can speed up some comparisons. These include BETWEEN, IN, LIKE, DISTINCT, and JOIN in randomized encryption scenarios.

For Dynamic Data Masking, ensure proactive protection by using Databarrison expressions. Mask data that protects specific, unique values. Also, mask the traditionally masked columns. This will let only specific users view the unmasked data. It will further enhance your organization’s privacy and security.
