AWS IAM is a core AWS security service used to control access to AWS resources. It manages users, groups, roles, and policies.
One important concept in IAM is the principle of least privilege. It means giving an identity only the permissions required to perform its task.
For example, instead of giving an application full S3 access, we can allow access only to a specific bucket.
IAM roles can also provide temporary credentials to services such as EC2, reducing the need to store long-term access keys.
Understanding IAM and least privilege is an important foundation for AWS Cloud Security.
