How do you define the scope and goals of test-driven security (TDS)?

2 Define the security requirements

The next step is to define the security requirements that specify how your project will achieve the security objectives. These requirements should be clear, measurable, testable, and prioritized. You can use techniques such as threat modeling, risk analysis, and security design patterns to help you identify and document the security requirements.

3 Write the security tests

The third step is to write the security tests that will verify whether your project meets the security requirements. These tests should cover both functional and non-functional aspects of security, such as encryption, authentication, authorization, logging, monitoring, and performance. You can use tools such as security testing frameworks, code analyzers, and vulnerability scanners to help you write and execute the security tests.

4 Implement the security solution

The fourth step is to implement the security solution based on the security tests. You should follow the TDD cycle of red-green-refactor, which means you should write a failing test first, then write the minimum code to make it pass, and then refactor the code to improve its quality and maintainability. You should also use version control, code review, and continuous integration to ensure the consistency and quality of your code.

5 Review and update the security tests and solution

The final step is to review and update the security tests and solution periodically to ensure they are still relevant and effective. You should monitor the security performance and feedback of your project, and identify any new threats, risks, or changes that may affect your security objectives and requirements. You should then update your security tests and solution accordingly, and repeat the TDD cycle as needed.
