Answer Posted / Shobhit Asthana
To protect against SQL Injection attacks, here are some methods followed in SQL Server:
1. Parameterized Queries: Use parameterized queries instead of concatenating user input directly into SQL statements.
2. Stored Procedures: Use stored procedures to validate and sanitize user input before using it in a query.
3. Prepared Statements: Similar to parameterized queries, prepared statements also help protect against SQL Injection attacks.
4. Least Privilege Principle: Grant the least amount of permissions needed for a task to the user or application.
5. Use of Dynamic SQL with Caution: While dynamic SQL is useful, it can be risky if not used carefully. Always sanitize user input before using it in dynamic SQL statements.
