Although system authorization is important; obtaining ATO is not the end; continuous monitoring provides ______________ that an information system remains secure following accreditation. Response:

Continuous monitoring is a critical component of the Risk Management Framework, providing ongoing validation and verification that security controls remain effective. This process gives management confidence, or assurance, that the system continues to meet its security requirements post-authorization.

Assumption implies a belief without proof, which contradicts the goal of continuous monitoring to actively verify security.

Anxiety is a feeling of worry, which is the opposite of the desired outcome of effective security practices.

Only 'Assurance' fits the context of what continuous monitoring provides in terms of security posture.
