# Policies for AWS

## Overview

{% hint style="info" %}
This page includes examples of all IAM and other policies necessary for a working StackState AWS Agent installation. For the AWS (legacy) integration, refer to the policy files provided when the AWS (legacy) StackPack is installed.
{% endhint %}

These policies are taken directly from the CloudFormation template and should be used wherever possible.

To use a template, replace the following values:

* **${Region}** - replace with the name of the region that the IAM role will be used for, such as `${Region}` or `us-east-1`.
* **${AccountId}** - replace with the 12-digit AWS account ID of the AWS account that the resources will be deployed in.

## StackStateAwsIntegrationRole

The JSON objects below include the least-privileged IAM policy used by the AWS integration. The Assume Role Policy Document should grant the Agent access. Refer to the AWS documentation for more information on [setting a trust policy (aws.amazon.com)](https://aws.amazon.com/blogs/security/how-to-use-trust-policies-with-iam-roles/).

### Trust Relationship

For an AWS Agent running outside of AWS, using an IAM user. Replace the Principal with the IAM user or AWS account that the Agent is using.

```javascript
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::${AccountId}:root"
        ]
      },
      "Action": "sts:AssumeRole",
      "Condition": {
        "StringEquals": {
          "sts:ExternalId": "${ExternalId}"
        }
      }
    }
  ]
}
```

For an AWS Agent running on an EC2 instance:

```javascript
{
  "Version": "2008-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```

### IAM Policy Document

## StackStateEventBridgeRole-${Region}

### Trust Relationship

```javascript
{
  "Version": "2008-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "events.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```

### IAM Policy Document

Replace the Resource with the ARN of the target Kinesis Firehose Delivery Stream.

```javascript
{
    "Statement": [
        {
            "Action": [
                "firehose:PutRecord",

            "Effect": "Allow"
        }
    ]
}
```

## StackStateFirehoseRole-${Region}

### Trust Relationship

```javascript

  "Version": "2008-10-17",
  "Statement": [
    {
      "Effect": "Allow",

      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```

### IAM Policy Document

The Condition and KMS sections are only needed if a KMS key is used. This assumes that the S3 bucket is named `stackstate-logs-${AccountId}`

```javascript

            ],

## StsEventBridgeRule

        "aws.sqs",
        "aws.states"
    ]
}
```

## stackstate-integration KMS Key

By default, this KMS key gives full access to any IAM user within the account to administer the key. This can be modified as necessary to meet your organization's security policies.

```javascript

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://archivedocs.stackstate.com/5.1/stackpacks/integrations/aws/aws-policies.md?ask=<question>&goal=<endgoal>

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
