Introduction
- IN AWS There are Two types of Users One is the AWS Root User and the other user is AWS Identity and Access Management User (IAM).
- AWS Account creation starts with one Identity that has complete access to all AWS services ( More than 200 services) Which is called AWS Root user, we can sign in as a root user with an Email id and password which is used while creating an account and for IAM user created by the Root user or IAM Administrator
Root User
- The Root user has complete access to all AWS services
- For the Creation of Accounts only we require a Root user, Instead, create a user and Access the AWS Services
- The root user has a complete set of permissions and should not be given to others
Instead of using Root, it's always advisable to create IAM User
What are IAM Services?
- IAM User
- IAM Groups
- IAM Policies
- IAM Roles
Detailed Explanation about IAM
I: Identity → Authorization
A: Access → Authentication
M: Management → Management
Identity
Identity is of Two Types
1) IAM User
2) IAM Role
IAM User
- In an organization, we have to allot IAM users to the employee
- The organization won't provide Root user Credentials to employees, Instead, it creates -
IAM User
- IAM User permits users to give external access to the AWS console
IAM Role
- IAM Role is also one type of identity
- IAM Role is Temporary access to the Service of AWS where Access key and Secret key are temporary and changes with time
- IAM Role is which permits Internal Access, which provides access and action upon all the services of AWS with required permissions
IAM Policies
- IAM Policy comes under Access Management
- IAM Policies are of two types they are
1) AWS Managed Policies
- These policies are Managed by AWS and we can say these are Predefined policies
- For Example :
a) Administrator Full Access
b) S3 Full permission
c) Read-only Access
2) Customer-managed Policies Fine grain permissions are managed by the customers and they write their own policies
- AWS Policy Exists in JSON Format
- It Includes :
{
"Version": "2012-10-17",
"Statement": [
{
"Action": "ec2:*",
