How do you manage user accounts and permissions in Amazon Lex, and how do you use AWS Identity and Access Management (IAM) for controlling access to resources?
To manage user accounts and permissions in Amazon Lex, utilize AWS Identity and Access Management (IAM). Create IAM users, groups, and roles to define access levels. Assign policies to these entities, specifying allowed or denied actions on specific resources.
For fine-grained control, use JSON-based policy documents with statements containing “Effect,” “Action,” “Resource,” and optional “Condition” elements. Use wildcards for multiple actions or resources.
To control access to Amazon Lex resources, create custom IAM policies or leverage AWS managed policies like “AmazonLexFullAccess” and “AmazonLexReadOnly.” Attach these policies to the appropriate IAM entities.
Use resource-level permissions to restrict access to specific bots, intents, or slots by including their Amazon Resource Names (ARNs) in the policy document.
Additionally, apply service control policies (SCPs) through AWS Organizations to set boundaries across your organization’s accounts.
