App Security Engineer Testing — Questions and Answers
Question 1: What is the primary purpose of application security testing?
- To enhance the user interface
- To identify vulnerabilities and weaknesses (Correct answer)
- To delay application deployment
- To eliminate the need for encryption
Correct answer: To identify vulnerabilities and weaknesses
Application security testing identifies vulnerabilities and weaknesses in software to prevent exploitation by attackers.
Question 2: Which type of security testing simulates real-world attacks to find vulnerabilities?
- Functional testing
- Penetration testing (Correct answer)
- Usability testing
- Unit testing
Correct answer: Penetration testing
Penetration testing simulates attacks to identify security flaws before malicious hackers can exploit them.
Question 3: Why is static application security testing (SAST) beneficial?
- It only works after deployment
- It identifies security flaws in source code early (Correct answer)
- It replaces penetration testing
- It slows down development
Correct answer: It identifies security flaws in source code early
SAST analyzes source code early in the development process to detect security issues before deployment.
Question 4: What is the primary focus of dynamic application security testing (DAST)?
- Checking user interface design
- Detecting vulnerabilities in running applications (Correct answer)
- Verifying application performance
- Testing internal APIs only
Correct answer: Detecting vulnerabilities in running applications
DAST tests applications while they are running to detect vulnerabilities that may not be visible in source code analysis.
Question 5: Which security testing method helps detect vulnerabilities in third-party dependencies?
- Unit testing
- Software composition analysis (SCA) (Correct answer)
- Load testing
- Code refactoring
Correct answer: Software composition analysis (SCA)
Software composition analysis (SCA) scans third-party libraries and dependencies for known vulnerabilities.
Question 6: Why is automated security testing important in application development?
- It eliminates the need for manual testing
- It ensures consistent and efficient vulnerability detection (Correct answer)
- It is only useful for small applications
- It replaces security best practices
Correct answer: It ensures consistent and efficient vulnerability detection
Automated security testing helps quickly identify vulnerabilities in large applications and ensures consistent testing across code changes.
