Authentication vulnerability testing in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is authentication vulnerability testing?

It is the process of checking if the login and identity verification parts of a system are safe from attacks that try to break in without permission.

beginner

Name a common authentication vulnerability.

Weak passwords or no limit on login attempts, which can let attackers guess passwords easily.

intermediate

Why is testing for session management important in authentication testing?

Because poor session handling can let attackers steal or reuse login sessions to access accounts without logging in again.

intermediate

What is brute force attack testing in authentication?

It is trying many passwords quickly to see if the system blocks or slows down attackers after wrong tries.

beginner

How can multi-factor authentication improve security?

By requiring more than one proof of identity, like a password plus a code sent to your phone, making it harder for attackers to get in.

What does authentication vulnerability testing mainly check?

A If the database is encrypted

B If the website loads quickly

C If login systems can be bypassed or broken

D If the user interface is user-friendly

Authentication vulnerability testing focuses on checking if login and identity checks can be bypassed or broken.

Which of these is a sign of a weak authentication system?

A Allows unlimited password attempts

B Requires strong passwords

C Uses multi-factor authentication

D Locks account after several failed tries

Allowing unlimited password attempts makes it easier for attackers to guess passwords.

What is the purpose of session management testing in authentication?

A To check if sessions can be stolen or reused

B To test website speed

C To verify database backups

D To check user interface colors

Session management testing ensures attackers cannot steal or reuse login sessions.

Which method helps protect against brute force attacks?

A No password required

B Allowing all login attempts

C Using simple passwords

D Account lockout after failed attempts

Locking accounts after several failed attempts stops attackers from guessing passwords endlessly.

Multi-factor authentication requires:

A Only a password

B More than one proof of identity

C No password

D Only a username

Multi-factor authentication asks for multiple proofs like password plus a code to increase security.

Explain why authentication vulnerability testing is important for software security.

Think about what happens if someone breaks into an account.

Describe common techniques used to test authentication vulnerabilities.

Consider how testers try to break login systems.
