Which AWS services should be included in the plan?

Explanations:

AWS CloudFormation can automate the provisioning of a trusted forensic environment, enabling rapid setup of resources for incident response and investigation.

Amazon GuardDuty is a threat detection service that identifies potential threats but does not directly support provisioning a forensic environment or orchestrating response.

Amazon Inspector focuses on security assessments and vulnerability scanning, not on automated response orchestration or setting up forensic environments.

Amazon Macie is used for discovering and classifying sensitive data, which is not directly relevant to forensic environments or incident response automation.

AWS Step Functions can automate response workflows, helping to orchestrate and manage response processes in a structured, automated way.
