Secure IAM Practices
Introduction
This article explores key aspects of secure Identity and Access Management (IAM).
Writing JSON Policies
IAM policies, often written in JSON, control access to resources. Well-structured policies are crucial for security.
{
"Version": "2012-10-17", "Statement": [{ "Effect": "Allow",
"Action": [
"s3:GetObject"
], "Resource": [
"arn:aws:s3:::my-bucket/*"
]
}]
}
Do You Know? JSON syntax is crucial for policy clarity and functionality.
Least-Privilege Access
Grant only the necessary permissions to users or groups. Avoid excessive privileges.
Important Note: Overly permissive policies increase the risk of data breaches.
Principle: Grant least privilege.Hands-on: Implementing Best Practices for Secure IAM Usage
