What are stored procedures' role in database security?

Short answer: Stored Procedures can help improve database security by encapsulating business logic and SQL statements in precompiled code, making it harder for attackers to inject malicious code.

Explain a bit more

Roles in database security: Input Validation: Stored procedures allow you to validate user inputs at the database level, preventing malicious input from being executed. Preventing Direct Access: By using stored procedures, users can be given permissions to execute specific procedures rather than direct access to the underlying tables. Encapsulation of Business Logic: The logic within stored procedures is not visible to the end-user, reducing the attack surface. Audit Logging: Stored procedures can include logic to log user activity for auditing and compliance purposes. Example: Instead of allowing users to execute arbitrary INSERT or UPDATE statements, you can give them permission to execute a specific stored procedure that does the necessary validation and modification of data. CREATE PROCEDURE update_salary(IN emp_id INT, IN new_salary DECIMAL) BEGIN IF new_salary > 0 THEN

Example code

UPDATE employees SET salary = new_salary WHERE id = emp_id; END IF; END;

Real-world example (ShopNest)

ShopNest’s SQL Server database stores customers, products, and orders. Good indexes and clear foreign keys keep checkout queries fast and safe.
