IAM Summary

Brief summary of the key points covered in the IAM section.

Key takeaways​

  • Users: Each IAM user should correspond to a real individual within the organization, complete with a unique password for accessing the AWS console.
  • Groups: Grouping users into specific groups allows for easier management of permissions. You can define access rights for both users and groups through policies or JSON documents.
  • Roles: Roles enhance flexibility in access management by serving as identities for AWS services, like EC2 instances, which are crucial for assigning permissions dynamically.
  • Security: MFA + Security Policy are important to strengthen user security.
  • AWS CLI: Manage AWS services using the command-line
  • AWS SDK: Manage AWS services using a programming language
  • Access Keys: For programmatic access, use access keys with caution, ensuring they are kept secure and not shared.
  • Audit: it's vital to audit IAM usage by creating an IAM credential reports and utilizing the IAM access advisor (Last Accessed) to monitor and review access permissions effectively.
