At what point in the SDLC should security policies, standards, and regulatory requirements be identified to ensure compliance?

Identifying security policies, standards, and regulatory requirements during the requirements gathering phase of the Software Development Life Cycle (SDLC) is crucial for several reasons. This phase is foundational because it sets the stage for all subsequent development activities. By incorporating security considerations early, teams ensure that the final product meets not only the functional requirements but also complies with necessary legal and regulatory mandates.

During requirements gathering, stakeholders can assess how specific policies and regulations apply to the project, ensuring that security is built into the system from the ground up rather than tacked on as an afterthought. This proactive approach allows for a more comprehensive understanding of the security landscape surrounding the project, leading to better risk management and alignment with organizational security goals.

Furthermore, many security requirements are dictated by external regulations and industry standards, which may directly influence design decisions and ultimately the architecture of the solution. By addressing these requirements upfront, the organization can also avoid costly rework or compliance issues later in the process, particularly in later stages like testing or deployment, where changes can be more difficult and expensive to implement.

This foundational approach to security within the SDLC not only enhances security posture but also fosters a culture of accountability and compliance throughout the development team.
