Why API security is critical in FastAPI - Quick Recap

Recall & Review

beginner

What is API security?

API security means protecting the API from unauthorized access, misuse, or attacks to keep data and services safe.

beginner

Why is API security important in FastAPI applications?

Because APIs often handle sensitive data and control important functions, securing them prevents data leaks, unauthorized actions, and service disruptions.

beginner

Name a common risk if API security is weak.

Attackers can steal user data, manipulate data, or overload the service causing it to crash.

beginner

How does authentication help API security?

Authentication checks who is using the API, allowing only trusted users to access it.

beginner

What role does encryption play in API security?

Encryption protects data sent between clients and the API so attackers cannot read it if intercepted.

What is a main reason to secure an API?

A To make the API slower

B To protect sensitive data and prevent unauthorized access

C To allow anyone to use the API freely

D To reduce the number of API endpoints

Securing an API protects sensitive data and controls who can use the API.

Which of these is NOT a common API security risk?

A Faster response time

B Data theft

C Unauthorized access

D Service overload

Faster response time is a performance benefit, not a security risk.

What does authentication do in API security?

A Blocks all users

B Encrypts data

C Deletes data

D Checks user identity

Authentication verifies who is using the API.

Why is encryption important for APIs?

A It hides data during transfer

B It speeds up the API

C It creates more API endpoints

D It removes user authentication

Encryption protects data from being read by attackers during transfer.

Which FastAPI feature helps improve API security?

A Template rendering

B Automatic UI generation

C Dependency injection for authentication

D Static file serving

FastAPI uses dependency injection to add authentication and security checks.
