An overview of Identity and Access Management (IAM) as a service to control access to AWS resources.

Creating individual accounts (users) with unique credentials for better access control and accountability.

Organize users into groups for simplified permission management and consistent policies.

Create temporary security credentials for AWS services or external users, avoiding long-term access keys.

Define permissions through JSON-based policies, controlling who can do what in AWS.

Enhance security by adding multi-factor authentication for IAM users, console logins, and privileged actions.

How to manage and rotate access keys, safeguarding credentials against unauthorized use.

Enforcing strong password requirements, expiration, and rotation for increased account security.

Using existing identity providers (SAML, OpenID) to enable single sign-on and reduce credential sprawl.

Monitoring IAM activities via CloudTrail and AWS Config for compliance and security oversight.

Identifying unintended public or cross-account access to resources using Access Analyzer insights.

Least privilege, regular policy audits, and rotating credentials to maintain strong security posture.

Regularly reviewing and updating policies to meet evolving requirements and maintain least privilege.

Using conditions, resource-level permissions, and policy variables for granular access control.

Configuring IAM roles for cross-account scenarios, trusting external AWS accounts, and restricting scope.

Assigning permissions to AWS services (e.g., Lambda, EC2) for secure operations without hard-coded credentials.

Limiting the maximum permissions an IAM entity can grant, preventing privilege escalation.

Centralizing user management via AWS SSO for simplified authentication and access across multiple AWS accounts.

Testing and troubleshooting IAM policies, simulating calls to confirm least privilege before deployment.

Handling compromised credentials, revoking sessions, and forensic analysis when IAM security is breached.
