All you need to know about writing Least Privilege IAM Policies

The system of AWS IAM Policies provides a granular structure of permission sets. The reason behind this system is Least Privilege Model. The least privileged principle allows IAM identities to have the least required access level to complete their tasks. And this is an important unit of Well Architectured best practices.

In AWS all operations are Implicitly denied until Explicitly Allowed using these policies. However, if an operation is Explicit Denied then this rule has the highest precedence.

Read about the Main principles of AWS Cloud Security and what role IAM plays in securing the AWS Resources.

Structure of IAM Policies

{    "Version" : "2012-10-17",    "Statement" :     [        {            "Sid" : "Human Readable Description",            "Effect" : "Allow/Deny",            "Action" :                 [                    "Service:api/call"                ],            "Resource" :                ["arn"],            "Condition" :             {                "Stringequals" :                     {                        "part of string" : "value to match"                    }            }        }    ]}
