Question 1

What is the purpose of Input Validation in API security?

To disable an API entirely To allow any data to be entered into an API To ensure data entered into an API is safe and follows certain rules To encrypt data entered into an API To bypass API authentication To cache API responses

Correct Answer: To ensure data entered into an API is safe and follows certain rules

Input validation is the process of ensuring that data entered into an API follows specified rules and is safe to use. It prevents attacks such as SQL injection and cross-site scripting (XSS) by filtering out potentially harmful input.

Question 2

What is the purpose of a DMZ?

To filter out unwanted traffic from the Internet. To provide a buffer zone between a trusted internal network and an untrusted external network. To provide secure remote access to internal resources. To speed up data transfer between networks. To block all incoming traffic from the Internet. To encrypt all traffic passing between networks.

Correct Answer: To provide a buffer zone between a trusted internal network and an untrusted external network.

A DMZ, or demilitarized zone, is a network segment that is used to provide a buffer zone between a trusted internal network and an untrusted external network.

Question 3

What is the purpose of OAuth in API security?

To encrypt API requests To bypass API rate limiting To cache API responses To block access to resources entirely To allow authenticated access to resources without sharing user credentials To allow unauthenticated access to resources

Correct Answer: To allow authenticated access to resources without sharing user credentials

OAuth is an authentication protocol that allows users to grant third-party applications access to their resources without sharing their credentials. This reduces the risk of data breaches and password theft. OAuth uses access tokens to grant authorized access to API resources.
