SQL injection protection via ORM in Django - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is SQL injection?

SQL injection is a security risk where attackers insert harmful SQL code into input fields to access or damage the database.

beginner

How does Django ORM help prevent SQL injection?

Django ORM uses parameterized queries automatically, which means it safely inserts user data without mixing it with SQL commands.

Why should you avoid raw SQL queries in Django?

Raw SQL queries can be vulnerable to SQL injection if not carefully handled, while ORM methods handle data safely by default.

beginner

What is a safe way to filter objects using Django ORM?

Use methods like Model.objects.filter(field=value) where 'value' is user input; Django safely escapes it to prevent injection.

intermediate

Can Django ORM completely eliminate SQL injection risks?

Yes, when used properly. But if you use raw SQL or unsafe string formatting, risks return. Always prefer ORM methods.

What does Django ORM do to protect against SQL injection?

A Runs queries twice to check for errors

B Encrypts the database

C Disables user input

D Automatically parameterizes queries to separate data from commands

Django ORM safely inserts user data by parameterizing queries, preventing harmful SQL code execution.

Which Django method is safer to use with user input?

A Directly inserting user input into SQL strings

B Model.objects.filter(field=user_input)

C Raw SQL with % formatting

D Using string concatenation to build SQL

Using ORM filter methods safely escapes user input, preventing SQL injection.

What risk increases when using raw SQL in Django without care?

A SQL injection

B Slower queries

C Automatic backups

D Better performance

Raw SQL can be vulnerable to injection if user input is not properly handled.

Which practice helps avoid SQL injection in Django?

A Always use ORM methods for queries

B Use raw SQL with string formatting

C Disable database logging

D Allow all user input without checks

ORM methods handle user input safely, reducing injection risks.

If you must use raw SQL in Django, what should you do?

A Ignore user input

B Concatenate strings directly

C Use parameterized queries with placeholders

D Use ORM instead

Parameterized queries safely insert user data even in raw SQL.
