-Proactive controls check resources whenever those resources are created or updated by means of CloudFormation stack operations. Specifically, these proactive controls are implemented as `preCreate` and `preUpdate` hook handlers. As a consequence, these controls may not affect requests that are made directly to services through the AWS console, through AWS APIs, or through other means such as AWS SDKs, or other Infrastructure-as-Code (IaC) tools.

Secure strings and secrets are not resolved before they are sent to the hook, which prevents the proactive control from evaluating the string.
