What does 'security by design' entail?

The concept of 'security by design' encompasses the integration of security measures into the development process from the very beginning. This proactive approach ensures that security considerations are embedded into every stage of the system design and development lifecycle, rather than being an afterthought or something that is added only after a system is in operation.

By integrating security from the outset, organizations can identify potential vulnerabilities early on, address them during development, and create systems that are fundamentally more secure. This is aligned with best practices in information security, as it fosters a culture of security awareness and minimizes the cost and complexity of implementing security measures later on. For instance, developers can adopt secure coding techniques, conduct threat modeling, and utilize security frameworks that guide decisions throughout the project.

In contrast, implementing security measures only after deployment or testing security measures post-implementation does not address risks until they have already been introduced into the systems. These approaches are reactive and can lead to significant vulnerabilities if not adequately addressed. Additionally, creating separate security teams for emergency response neglects the principle of building security into the system from the very start and instead focuses on remedial actions rather than prevention. Therefore, the essence of 'security by design' lies in a comprehensive and proactive method, which is best captured by integrating
