SQL Server Security Best Practices

Configure a Secure SQL Server Login

Create a SQL Server login with a strong password and assign it only read permissions on a test database.

Expected output: A login that can connect and read data but cannot modify or delete data.

Hint: Use CREATE LOGIN, CREATE USER, and assign the db_datareader role.

Enable Transparent Data Encryption

Enable TDE on a sample database and verify that the database files are encrypted.

Expected output: The database is encrypted at rest, confirmed by querying encryption state.

Hint: Create a database encryption key and use ALTER DATABASE to set encryption ON.

Set Up SQL Server Audit

Configure an audit to track failed login attempts and review the audit logs.

Expected output: Audit logs capturing failed login events.

Hint: Use SQL Server Audit feature and specify the audit action type.

It means granting users the minimum permissions necessary to perform their job functions, reducing the risk of unauthorized access or accidental data exposure.

TDE encrypts the entire database at the file level, protecting data at rest including backups, without requiring changes to the application.

Windows Authentication integrates with Active Directory, providing centralized credential management, stronger security protocols, and easier administration.
