Why is the early selection of assessors important to organizations implementing a systems security engineering approach? Response:

Assessors do not necessarily assess all implemented security controls, but rather a subset or specific controls as part of the overall assessment strategy.

Early selection of assessors is crucial because they provide continuous support for verification and validation activities from the initial stages through the entire system development lifecycle. This integration helps identify and address security issues proactively, ensuring the system meets its security objectives effectively.

Early selection of assessors enhances security by integrating expertise, not violating security requirements.

While timely completion of assessments is a goal, the primary importance of early selection is the continuous support for verification and validation, which contributes to timely completion but is not the sole reason.
