Master the Secure Software Testing Domain

Test your knowledge in the Secure Software Testing domain with these 5 practice questions. Each question is designed to help you prepare for the CSSLP certification exam with detailed explanations to reinforce your learning.

Question 1

A company is integrating security testing into its CI/CD pipeline for a cloud-based application. Which of the following activities should be prioritized to identify vulnerabilities early in the development process?

A) Performing static application security testing (SAST) during the build stage.

B) Conducting penetration testing after deployment to the production environment.

C) Implementing runtime application self-protection (RASP) in the production environment.

D) Scheduling regular security audits of the CI/CD pipeline.

Show Answer & Explanation

Correct Answer: A

Explanation: Performing static application security testing (SAST) during the build stage helps identify vulnerabilities early in the development process, allowing developers to address issues before the application is deployed. Penetration testing and RASP are more effective post-deployment, and security audits, while important, do not directly identify vulnerabilities in the code.

Question 2

A development team is preparing for a release of a new mobile application that must comply with strict data privacy regulations. As part of their secure software testing, what should they focus on to ensure compliance?

A) Conducting a comprehensive review of the application's privacy policy.

B) Performing data flow analysis to ensure proper handling of sensitive information.

C) Implementing encryption for all data at rest and in transit.

D) Ensuring all third-party libraries used are updated to their latest versions.

Show Answer & Explanation

Correct Answer: B

Explanation: Performing data flow analysis is crucial to ensure that sensitive information is handled properly and complies with data privacy regulations. This analysis helps identify how data is collected, processed, and stored. Reviewing the privacy policy (Option A) is important but does not directly verify compliance in the application itself. Implementing encryption (Option C) is necessary but should be part of a broader compliance strategy. Keeping third-party libraries updated (Option D) is good practice but not directly related to data privacy compliance.

Question 3

A company is developing a legacy system upgrade and needs to ensure the security of the new software. The development team is concerned about introducing vulnerabilities during the integration of old and new code. What testing approach should be used to address this concern?

A) Perform regression testing to ensure new code does not affect existing functionality.

B) Use fuzz testing to identify potential input-based vulnerabilities.

C) Conduct integration testing to verify that old and new code work together securely.

D) Implement peer code reviews to identify potential security flaws.

Show Answer & Explanation

Correct Answer: C

Explanation: Integration testing is crucial in this context as it ensures that the old and new code integrate securely, preventing the introduction of vulnerabilities during the upgrade process.

Question 4

During a security review of a software project, it was discovered that the application relies heavily on third-party open-source libraries. To mitigate supply chain risks, what is the most appropriate action for the team to take?

A) Remove all open-source libraries and replace them with proprietary solutions.

B) Implement a Software Bill of Materials (SBOM) and regularly update the libraries.

C) Conduct a one-time security audit of all third-party libraries.

D) Isolate open-source components in a separate environment to limit their impact.

Show Answer & Explanation

Correct Answer: B

Explanation: Implementing a Software Bill of Materials (SBOM) provides visibility into the components used and helps manage and update them regularly, which is crucial for mitigating supply chain risks. Removing all open-source libraries is impractical and costly. A one-time audit is insufficient for ongoing security, and isolating components does not address vulnerabilities within the libraries themselves.

Question 5

A software development team is using open-source components in their project. To manage risks associated with these components, what is the MOST effective action they should take?

A) Regularly update the open-source components to the latest versions.

B) Conduct threat modeling sessions focused on open-source components.

C) Create a Software Bill of Materials (SBOM) to track all open-source components.

D) Isolate open-source components in a separate repository.

Show Answer & Explanation

Correct Answer: C

Explanation: Creating a Software Bill of Materials (SBOM) to track all open-source components is the most effective action for managing risks. An SBOM provides visibility into the components used, enabling better risk assessment and management. Regular updates (A) are important but not sufficient on their own. Threat modeling (B) is useful but more strategic when combined with an SBOM. Isolating components (D) does not inherently manage risk without visibility and tracking.
