AWS Simplified – Day 7: AWS IAM Policies, Groups & Roles
Save this for quick revision & follow for more 👇
1️⃣ IAM Policies:
- IAM Policies define what actions are allowed or denied in AWS.
- They are written in JSON and attached to IAM entities.
Types of IAM Policies:
👉 AWS-Managed Policies: Predefined by AWS. Examples: AdministratorAccess, ReadOnlyAccess
👉 Customer-Managed Policies: Custom policies created by users, Reusable across multiple users, groups, and roles
👉 Inline Policies: Policies directly attached to a single IAM entity (User / Group / Role)
-------------------------------------------
2️⃣ IAM Groups:
- IAM Groups help manage permissions for multiple users at once.
- Users inherit permissions from the group.
- Makes permission management scalable and clean.
- Best Practice: Assign policies to groups, not individual users.
Example Groups:
AdminGroup → Full access
DevGroup → Limited access
ReadOnlyGroup → Read-only permissions
-------------------------------------------
3️⃣ IAM Roles
- IAM Roles provide temporary permissions.
⚠️ Roles do NOT have long-term credentials (unlike IAM users)
- Used for: AWS services (EC2, Lambda, ECS, etc.)
- Cross-account access
- Federated access (SSO, Active Directory)
👉 IAM Role – Real-World Example:
- EC2 needs access to S3
Steps:
1️⃣ Create an IAM Role with required S3 permissions
2️⃣ Attach the role to the EC2 instance
3️⃣ EC2 automatically receives temporary credentials
- No access keys
- No secret keys
- Secure by design
That's it for today.

🔐 AWS IAM (Identity and Access Management)
- AWS IAM user is a service provided by Amazon Web Services that allows you to manage access to AWS resources within your organization.
- User authentication: IAM users can be used to authenticate users who need to access AWS resources or services.
- Resource access control: IAM users can be assigned permissions to access specific AWS resources or services.
- Cost-effective: IAM users can help you control costs by limiting access to resources and services only to those who need them.
- Security management: IAM users can be used to manage security and compliance within your organization.
- You can set up policies and roles that define what actions are allowed or denied for specific users.
- Each IAM User is associated with one and only one AWS ROOT account.
That's it for the day tomorrow I will cover:
IAM Policies, IAM Groups, IAM Roles
Stay Tuned !!
