What does the concept of "security by design" entail?

The concept of "security by design" fundamentally involves integrating security practices throughout the entire system development lifecycle, rather than treating security as an afterthought. This proactive approach ensures that security considerations are embedded in every stage of development, from initial design to deployment and maintenance. By incorporating security measures from the outset, organizations can better identify potential vulnerabilities and mitigate risks early on. This not only enhances the overall security posture of the system but also reduces the likelihood of costly fixes later in the process.

The emphasis of this concept lies in fostering a culture of security awareness among developers and stakeholders, which leads to more secure software and system infrastructures that are resilient against emerging threats.
