CISSP Software Development Security — Questions and Answers
Question 1: What is the primary benefit of version control in software development security for CISSP?
- It makes files larger
- It tracks changes and enables collaboration (Correct answer)
- It replaces testing
- It eliminates the need for documentation
Correct answer: It tracks changes and enables collaboration
Version control systems track all changes to code and configurations, enabling collaboration, rollback, and audit trails.
Question 2: Which principle is fundamental to good software development security practice?
- Writing as much code as possible
- Separation of concerns and modularity (Correct answer)
- Avoiding all abstraction
- Never refactoring code
Correct answer: Separation of concerns and modularity
Separation of concerns and modularity make code easier to understand, test, maintain, and extend over time.
Question 3: In CISSP certification, what is the purpose of automated testing?
- To replace manual code review entirely
- To catch regressions and verify functionality continuously (Correct answer)
- To slow down development
- To increase server costs
Correct answer: To catch regressions and verify functionality continuously
Automated testing catches regressions early and verifies that functionality works as expected, providing confidence in code changes.
Question 4: What is the recommended approach for handling errors in software development security?
- Suppress all error messages
- Implement structured error handling with meaningful messages (Correct answer)
- Let errors crash the application
- Log errors but never handle them
Correct answer: Implement structured error handling with meaningful messages
Structured error handling with meaningful messages helps diagnose problems quickly while maintaining application stability and user experience.
Question 5: Which practice improves the security of software development security implementations?
- Using default credentials
- Input validation and principle of least privilege (Correct answer)
- Disabling all logging
- Granting maximum permissions to all users
Correct answer: Input validation and principle of least privilege
Input validation prevents injection attacks while the principle of least privilege limits the damage potential of any compromised component.
Question 6: What is the benefit of continuous integration in CISSP workflows?
- It eliminates the need for development environments
- It detects integration issues early through frequent builds and tests (Correct answer)
- It removes the need for code review
- It automatically fixes all bugs
Correct answer: It detects integration issues early through frequent builds and tests
Continuous integration detects integration issues early by automatically building and testing code whenever changes are committed.
