Why is a security impact analysis included in migration planning?

Including a security impact analysis in migration planning is crucial for understanding the security implications associated with transitioning to a new system or architecture. When organizations migrate from one state to another, they often face different threat landscapes, vulnerabilities, and security requirements. By conducting a security impact analysis, the organization can identify potential security risks, assess how these risks may differ in the target state, and develop appropriate mitigations to ensure that the new system is secure.

This analysis informs decision-makers about the necessary security controls that need to be implemented during the migration process. It also helps in understanding how the security posture of the organization might change as a result of the migration, ensuring that the new architecture adheres to the desired levels of confidentiality, integrity, and availability.

While financial risks and team readiness are also important considerations in migration planning, they do not directly address the specific security consequences of moving to a new architecture. Similarly, compliance with regulatory requirements is essential, but it typically falls under the broader umbrella of security considerations rather than addressing the security impacts specific to the migration itself.
