A Detailed Guide to the OWASP Top 10 - API2:2023 Broken Authentication

The video tutorial explains the difference between authentication and authorization, emphasizing that authentication verifies a user's identity before authorization determines their access rights. It uses a hotel check-in analogy to illustrate these concepts. The tutorial then discusses broken authentication vulnerabilities, highlighting how login pages are often easy targets. It identifies signs of vulnerable APIs and provides strategies to prevent such vulnerabilities, including adhering to security standards and implementing multi-factor authentication.

What is the primary purpose of authentication in a security system?

• To verify a user's identity

• To encrypt user data

• To provide access to resources

• To determine what a user can do

In the hotel analogy, what does authorization determine?

• The guest's access to amenities

• The guest's room number

• The guest's identity

• The guest's payment method

Why is broken authentication considered an easy target for attackers?

• Because it is only used by select users

• Because it uses complex encryption

• Because login pages are often publicly accessible

• Because it requires multi-factor authentication

What should be avoided in URLs to prevent broken authentication vulnerabilities?

• Sensitive authentication details

• Usernames

• Session IDs

• Page titles

What is a common method attackers use to exploit broken authentication?

• Denial of service

• Brute force attacks

• Phishing attacks

• Social engineering

Which of the following is NOT a recommended strategy to prevent broken authentication?

• Securing password recovery processes

• Implementing multi-factor authentication

• Using established security standards

• Reinventing authentication mechanisms

What is a key feature of multi-factor authentication?

• It relies on a single security question

• It requires multiple forms of verification

• It uses only passwords

• It is optional for all users
