A this security by design, the best practice for building secure systems from the ground up. It avoids costly repairs later

The best answer is: A. Originally designed to provide necessary security Security is most effective and economical when it is integrated into the system from the beginning rather than added later as an afterthought. This approach, often referred to as "security by design," ensures that security controls are inherently built into the system, reducing vulnerabilities and the cost of retrofitting security measures.

C. Customized to meet specific security threats: The most effective and economical security is one that is tailored to the specific needs and threats faced by an organization or system. By customizing security controls and measures, the organization ensures that it is addressing the unique risks it faces, rather than applying generic or unnecessary security measures. This allows for more targeted defenses and can be more cost-effective, as resources are focused on mitigating actual threats rather than generic ones.
