A software development team is adopting a 'secure by design' approach for their new application. Which of the following best describes a key characteristic of this approach?
- AIntegrating security considerations and controls from the very beginning of the application's lifecycle.
- BImplementing security measures primarily during the testing phase to identify vulnerabilities.
- COutsourcing all security responsibilities to a third-party vendor after development is complete.
- DAdding security patches and updates only after the application has been deployed and vulnerabilities are discovered.
Show answer & explanationAnswer & explanation
Correct answer: A. Integrating security considerations and controls from the very beginning of the application's lifecycle.
Secure by Design emphasizes integrating security into every phase of the software development lifecycle (SDLC), starting from conception and design, rather than treating it as an afterthought. This proactive approach aims to prevent vulnerabilities from being introduced in the first place.
Why the other options are wrong
- B. Implementing security during the testing phase is a reactive approach to finding vulnerabilities, not a proactive 'secure by design' principle.
- C. Outsourcing security responsibilities after development is complete does not integrate security into the design phase itself.
- D. Adding security patches and updates after deployment is a reactive incident response and maintenance activity, not a 'secure by design' approach.
Secure by Design
An approach to software and system development that mandates security be considered and integrated into every stage of the development lifecycle, starting from the initial design and requirements gathering, rather than being added as an afterthought or fix.
- Proactive approach to security.
- Aims to prevent vulnerabilities rather than remediate them.
- Reduces costs and risks associated with security flaws.
Memory trick: Secure by Design is like building a house with strong foundations and locks from the start, not adding them after it's built.
