How is SQL injection prevented?

Show Suggested Answer Hide Answer
Suggested Answer: B

SQL injection is a type of injection attack where malicious SQL statements are inserted into an entry field for execution.

The primary way to prevent SQL injection is by validating and sanitizing user input. This involves checking the input for malicious content and ensuring it adheres to expected patterns.

Prepared statements (parameterized queries) are also highly effective, as they treat user input as data rather than executable code.

Implementing these practices ensures that any input received from users does not manipulate SQL queries in a harmful way.
