In today's cloud-centric environment, data security is more crucial than ever. One of the common challenges faced by organizations is ensuring that sensitive data stored in AWS S3 buckets is accessible only under strict conditions. This blog post delves into a hands-on session where we set up an AWS Key Management Service (KMS) policy to restrict access to a single S3 bucket using a customer's own encryption key.

Introduction to AWS S3 and KMS​

Amazon Web Services (AWS) offers robust solutions for storage and security. S3 (Simple Storage Service) provides scalable object storage, and KMS offers managed creation and control of encryption keys.

Scenario Overview​

The need: A customer wants to use their own encryption key and restrict its usage to a single S3 bucket. This ensures that no other buckets can access the key.

Setting Up the KMS Key​

Step 1: Creating the Key​

• Navigate to the Key Management Service: Start by opening the AWS Management Console and selecting KMS.
• Create a new key: Choose the appropriate options for your key. For simplicity, skip tagging and advanced options during this tutorial.

Step 2: Configuring Key Policies​

• Permission settings: Initially, you might be tempted to apply broad permissions. However, to enhance security, restrict the key’s usage to a specific IAM user and apply a policy that denies all other requests.

Crafting a Bucket Policy​

Step 1: Creating the Bucket​

• Unique bucket name: Remember, S3 bucket names need to be globally unique. Create the bucket intended for the exclusive use of the KMS key.
• Disable bucket versioning: If not required, keep this setting disabled to manage storage costs.

Step 2: Policy Configuration​

• Deny other buckets: The crucial part of this setup involves crafting a bucket policy that uses a "Deny" statement. This statement should specify that if the bucket name doesn’t match your specific bucket, access should be denied.
• Set conditions: Use conditions to enforce that the KMS key can only encrypt/decrypt objects when the correct S3 bucket is specified.

{
    "Version": "2012-10-17",
    "Id": "key-consolepolicy-3",
    "Statement": [
        {
            "Sid": "Enable IAM User Permissions",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<account-number>:root"
            },
            "Action": "kms:*",
            "Resource": "*"
        },
        {
            "Sid": "Deny access to key if the request is not for a yt-test-bucket",
            "Effect": "Deny",
            "Principal": {
                "AWS": "*"
            },
            "Action": [
                "kms:GenerateDataKey",
                "kms:Decrypt"
            ],
            "Resource": "*",
            "Condition": {
                "StringNotEquals": {
                    "kms:EncryptionContext:aws:s3:arn": "arn:aws:s3:::yt-s3-bucket"
                }
            }
        }
    ]
}

Testing the Configuration​

• Validate with another bucket: Create an additional S3 bucket and try to use the KMS key. The attempt should fail, confirming that your policy works.
• Verify with the correct bucket: Finally, test the key with the correct bucket to ensure that operations like uploading and downloading are seamless.

Conclusion​

The Need for Handling Bounces and Complaints​

Managing bounces and complaints efficiently is crucial for maintaining your organization’s email sender reputation. High rates of bounces or complaints can affect your ability to deliver emails and could lead to being blacklisted by email providers.

Step-by-Step Setup​

Step 1: Configuring SES​

First, configure your AWS SES to handle outgoing emails. This involves:

• Setting up verified email identities (email addresses or domains from which you'll send emails).
• Creating configuration sets in SES to specify how emails should be handled and tracked.

Step 2: Integrating SNS for Notifications​

The next step is to set up AWS SNS to receive notifications from SES. This is crucial for real-time alerts on email bounces or complaints:

• Create an SNS topic that SES will publish to when specified events (like bounces or complaints) occur.
• Configure your SES configuration set to send notifications to the created SNS topic.

          "AWS:SourceArn": "arn:aws:ses:*"
        }
      }
    }
  ]
}

Step 3: Using AWS Lambda for Automated Responses​

With SNS in place, integrate AWS Lambda to automate responses based on the notifications:

• Create a Lambda function that will be triggered by notifications from the SNS topic.
• Program the Lambda function to execute actions like logging the incident, updating databases, or even triggering remedial workflows.

In the realm of Azure, messaging services play a critical role in facilitating communication and data flow between different applications and services. With Azure's Service Bus, Event Hub, and Event Grid, developers have powerful tools at their disposal to implement robust, scalable, and efficient messaging solutions. But understanding the differences, use cases, and how to leverage each service optimally can be a challenge. This blog aims to demystify these services, providing clarity and guidance on when and how to use them.

Adapting to change is not about holding onto a single solution but exploring a spectrum of possibilities. Azure Messaging services—Service Bus, Event Hub, and Event Grid—embody this principle by offering diverse paths for seamless communication and data flow within cloud architectures.

Before diving into the specific Azure messaging services, it's essential to differentiate between two key concepts: events and messages.

Events​

Events signify a state change or a condition met, alerting the system that something has happened. They are lightweight and only provide information that an action has occurred, leaving it to the recipient to determine the response. Events can be singular or part of a sequence, providing insights without carrying the original data payload.

Messages​

Messages, on the other hand, contain data intended for processing or storage elsewhere. They imply an agreement on how the data will be handled by the recipient, ensuring that the message is processed as expected and acknowledged upon completion.

1. In account 2, open the IAM console.
2. In the navigation pane, choose Policies. Then, choose Create policy.
3. Choose the JSON tab. Then, enter the following policy into the JSON editor:
Important: Replace arn:aws:kms:REGION:ACCOUNT_A_NO:key/key-id with your AWS KMS key's ARN that you copied earlier.

{
      'Action' : [
        'kms:DescribeKey',
        'kms:GenerateDataKey',
        'kms:Decrypt',
        'kms:CreateGrant',
        'kms:ReEncrypt*',
        'kms:Encrypt'
    ],
    'Resource': [
        'arn:aws:kms:us-east-1: <<Account 1>>:key/f031942c-5c7b-4e9f-9215-56be4cddab51'
    ],
    'Effect': 'Allow',
    'Sid': 'KMSAccess'
  }

4. Choose Review policy.
5. For Name, enter a name for the policy.
6. Choose Create policy.

Create the cross-account IAM role using the policies that you created​

1. In account 2, open the IAM console.
2. In the navigation pane, choose Roles.
3. Choose Create role.
4. Choose Another AWS account.
5. For Account ID, enter the account 1 account ID.
6. Choose Next: Permissions. Then, complete the steps to create the IAM role.
7. Attach the cross-account role policy and KMS key policy to the role that you created. For instructions, see Adding and removing IAM identity permissions.

(Account 1) Add the AssumeRole permission to the account 1 CodePipeline service role to allow it to assume the cross-account role in account 2​

1. In account 1, open the IAM console.
2. In the navigation pane, choose Roles.
3. Choose the IAM service role that you're using for CodePipeline.
4. Choose Add inline policy.
5. Choose the JSON tab. Then, enter the following policy into the JSON editor:

Important: Replace ACCOUNT_B_NO with the account 2 account number.​

{
  'Version': '2012-10-17',
  'Statement': {
    'Effect': 'Allow',
    'Action': 'sts:AssumeRole',
    'Resource': [
      'arn:aws:iam::ACCOUNT_B_NO:role/*'
    ]
  }
}

6. Choose Review policy, and then create the policy.

(Account 2) Create a service role for CodeDeploy and if using EC2 you need to also setup AutoScaling for EC2 service role that includes the required permissions for the services deployed by the stack​

Note:

1. In account 2, open the IAM console.

2. In the navigation pane, choose Roles.

3. Create a role for AWS CloudFormation to use when launching services on your behalf.

4. Apply permissions to your role based on your use case.

Important: Make sure that your trust policy allows resources in Account 1: < Account 1 > 0 to access services that are deployed by the stack.

(Account 1) Update the CodePipeline configuration to include the resources associated with account 2​

Note: If you receive errors when running AWS Command Line Interface (AWS CLI) commands, confirm that you're running a recent version of the AWS CLI.

You can't use the CodePipeline console to create or edit a pipeline that uses resources associated with another account. However, you can use the console to create the general structure of the pipeline. Then, you can use the AWS CLI to edit the pipeline and add the resources associated with the other account. Or, you can update a current pipeline with the resources for the new pipeline. For more information, see Create a pipeline in CodePipeline.

1. Get the pipeline JSON structure by running the following AWS CLI command: aws codepipeline get-pipeline --name MyFirstPipeline >pipeline.jsonCopy CodeCopy CodeCopy CodeCopy CodeCopy CodeCopy CodeCopy CodeCopy CodeCopy Code

2. In your local pipeline.json file, confirm that the encryptionKey ID under artifactStore contains the ID with the AWS KMS key's ARN. Note: For more information on pipeline structure, see create-pipeline in the AWS CLI Command Reference.

3. The RoleArn inside the 'name': 'Deploy' configuration JSON structure for your pipeline is the role for the CodePipeline role in Account 2. This is IMPORTANT as using this role the pipeline in Account 1 will be able to know the ECS Service/task is in which account.

4. Verify that the role is updated for both of the following:

a. The RoleArn inside the action configuration JSON structure for your pipeline.

b. The roleArn outside the action configuration JSON structure for your pipeline.

Note: In the following code example, RoleArn is the role passed to AWS CloudFormation to launch the stack. CodePipeline uses roleArn to operate an AWS CloudFormation stack.
