Security

AWS IAM

Manages identities, roles, permissions, and least-privilege access.

Key points

  • Controls access to AWS services and resources through users, groups, roles, and policies.
  • Supports least privilege by granting only the actions and resources required.
  • Roles provide temporary credentials and are preferred for AWS services and federated workloads.
  • Policy evaluation combines identity policies, resource policies, permission boundaries, and organization controls where used.
  • Is central to securing AI services, data sources, model endpoints, logs, and automation.

When to use it

  • Choose IAM when the question asks who can access an AWS AI service or resource.
  • Use roles for applications, Lambda functions, SageMaker jobs, Bedrock integrations, and cross-account access.
  • Use least-privilege policies to limit access to datasets, models, prompts, and administrative actions.

Exam tips

  • IAM authorizes access; CloudTrail records API activity after requests are made.
  • Do not use long-term user access keys when a role or federation pattern fits better.
  • Least privilege is a recurring AIF-C01 security and governance principle.
  • IAM does not encrypt data; KMS manages encryption keys.

Exam fidelity: AWS lists multiple choice and multiple response for this exam. Ordering, matching, and case-study items are supplemental learning exercises; their results stay in overall study accuracy but do not count toward exam-style accuracy. Difficulty labels describe this site's scenario complexity, not an AWS-published question rating.
