IAM Best Practices in AWS

To ensure a secure and well-managed AWS environment, follow these IAM best practices to avoid common security mistakes.

1. Minimize Use of the Root Account

🚨 Only use the root account for initial setup!

• After setting up your AWS account, create a separate IAM user for daily operations.
• Enable Multi-Factor Authentication (MFA) on the root account for added security.

2. Follow the One User = One Physical Person Rule

👤 Every AWS user should represent a real individual.

• Never share your AWS credentials with anyone.
• If a friend or colleague needs access, create a new IAM user for them.

3. Use Groups for Managing Permissions

🔹 Instead of assigning permissions individually:

• Create IAM groups (e.g., Admins, Developers, Viewers).
• Assign permissions to groups so users automatically inherit the right access.
• This makes permission management simpler and scalable.

4. Enforce a Strong Password Policy
