AWS IAM Deep Dive
The article provides a comprehensive overview of AWS Identity and Access Management (IAM), explaining how authentication and authorization work within the platform. It details the roles, policies, and mechanisms like SigV4 that secure access to AWS services. The guide emphasizes best practices such as avoiding root user usage and preferring short-lived credentials through IAM roles.
- ▪Every action on AWS goes through an HTTPS API protected by IAM.
- ▪IAM distinguishes between authentication (verifying who the caller is) and authorization (determining what they can do).
- ▪IAM Roles provide short-lived credentials via STS, reducing the risk of long-term access key exposure.
- ▪SigV4 is AWS's method for verifying that an API request was signed by a legitimate principal.
- ▪The root user should be secured with MFA and used only for specific account-level tasks.
