AWS accounts often require minimal viable permissions (MVP) assigned to user groups for security purposes.Implementing the principle of least privilege is crucial when working with powerful tools like Amazon Bedrock and Langchain.Key actions for Langchain integration with Bedrock include bedrock:InvokeModel, bedrock:ListFoundationModels, and bedrock:GetFoundationModel.Best practices include using IAM roles, regular audits of IAM policies, and setting environment-specific permissions.
