In today's fast-paced IT environments, maintaining control over user permissions and group memberships is crucial for security and compliance. AWS Identity Center (formerly known as AWS SSO) simplifies identity management across AWS, but monitoring changes in real-time can be challenging. This blog explores a serverless solution using AWS EventBridge and Lambda to notify you whenever key changes occur within your Identity Center.

Organizations often struggle with visibility into real-time changes within their identity management systems. Whether it's a new user being added, a permission change, or a group deletion, staying informed about these changes can help mitigate security risks and ensure compliance.

Setting Up the AWS Architecture

Step 1: Overview of AWS EventBridge and Lambda

AWS EventBridge is an event bus service that enables you to build event-driven applications using events generated from your AWS services, applications, or SaaS applications that you use. AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers.

Step 2: Creating EventBridge Rules

1.Navigate to the AWS Management Console and open the Amazon EventBridge service. 2.Create a Rule: Set up an event pattern to detect specific activities such as user additions, permission changes, or group deletions within AWS Identity Center. 3.Configure the Event Pattern: You may not find pre-configured templates for Identity Center, so you'll need to create a custom pattern. Here's an example of what your event pattern might look like:

{

  "source": ["aws.identitycenter"],
  "detail-type": ["AWS API Call via CloudTrail"],
  "detail": {
    "eventName": ["CreateGroup", "UpdateGroup", "DeleteGroup"]
  }
}

Step 3: Configuring AWS Lambda

1.Create a Lambda Function: Navigate to AWS Lambda and create a new function to process the events. 2.Set Up Permissions: Ensure your Lambda function has the necessary permissions to access EventBridge and perform actions based on the event data. 3.Implement Logic: Write the code to handle different types of events. For example, send notification emails or log entries to an S3 bucket for further analysis.

Step 4: Integrating EventBridge with Lambda

After creating the Lambda function, link it to the EventBridge rule as a target. This integration ensures that your Lambda function is triggered whenever the specified changes occur in AWS Identity Center.

Testing and Validation

Before going live, thoroughly test the setup by simulating the defined events and verifying that the Lambda function triggers appropriately and performs the intended actions.

Conclusion

Setting up real-time notifications for changes in AWS Identity Center using EventBridge and Lambda provides greater visibility and enhances security across your AWS environment. With this serverless approach, you can automate responses to critical events and maintain robust governance over your cloud resources.

AWS Key Management Service (KMS) provides a secure, centralized platform for managing cryptographic keys. Multi-Region keys in AWS KMS allow you to use the same keys across multiple AWS Regions, making it easier to manage encrypted data and ensuring business continuity. In this guide, we'll explore how to set up and use Multi-Region

BYOK (Bring Your Own Key) in AWS KMS.

Step 1: Setting Up Your Environment

Before you start, ensure you have an AWS account with the necessary permissions, AWS CLI installed, and familiarity with AWS regions and KMS concepts.

Creating an Empty Directory on EC2 Instance:

Start by creating a new directory on your EC2 instance where you'll manage your keys:

mkdir /opt/vb-hsm/hsm-21
cd /opt/vb-hsm/hsm-21

Step 2: Creating a Multi-Region KMS Key

Multi-Region KMS Multi-Region KMS

Generate a new KMS key with no key material associated, indicating it's external and multi-region:

aws kms create-key --origin EXTERNAL --region us-east-1 --multi-region

You'll receive an output similar to this:

{
    "KeyMetadata": {
        "AWSAccountId": "<AccountID>",
        "KeyId": "mrk-d58582b2563a40ef893d9181052130db",
        "Arn": "arn:aws:kms:us-east-1:<AccountID>:key/mrk-d58582b2563a40ef893d9181052130db",
        ...
        "MultiRegion": true,
        ...
    }
}

Make sure to note down the KeyId as it will be used later.

Step 3: Preparing for Key Import

Create an alias for easier reference to your key:

aws kms create-alias --alias-name alias/byok-mrk --target-key-id mrk-d58582b2563a40ef893d9181052130db

Retrieve the parameters needed for importing your key:

aws kms get-parameters-for-import --key-id mrk-d58582b2563a40ef893d9181052130db --wrapping-algorithm RSAES_OAEP_SHA_256 --wrapping-key-spec RSA_2048 --region us-east-1 > ./WrappingParameters.json

Extract the import token and create a public key:

jq -r '.ImportToken' ./WrappingParameters.json > ./ImportToken.b64
echo -e "-----BEGIN PUBLIC KEY-----\n$(jq -r '.PublicKey' ./WrappingParameters.json)\n-----END PUBLIC KEY-----" > ./PublicKey.pem
openssl enc -d -base64 -A -in ./ImportToken.b64 -out ./ImportToken.bin

Step 4: Importing Key Material

Initialize your Crypto user and import settings:

export CLOUDHSM_ROLE=crypto-user
export CLOUDHSM_PIN=cu_user1:acord12345
/opt/cloudhsm/bin/cloudhsm-cli key import pem --path ./PublicKey.pem --label wrapping-key-example-21 --key-type-class rsa-public --attributes wrap=true

What are Permission Sets?​

1. Definition Permission Sets are collections of permissions that define what users and groups can do within AWS accounts and applications.

2. Analogy Think of Permission Sets as 'access templates' that you can apply to users across different AWS accounts. A set of IAM policies that can be attached to users or groups to grant them access to AWS resources.

Characteristics​

1. Reusable Once created, a Permission Set can be assigned to any number of users or groups across different AWS accounts.

2. Customizable You can create Permission Sets that align with the specific job roles within your organization, ensuring that each role has access to the resources needed for its responsibilities.

3. Manageable AWS Identity Center allows you to manage Permission Sets centrally, giving you the ability to update permissions across multiple accounts from a single interface.

Components of a Permission Set​

1. IAM Policies Defines the permissions to access AWS resources. These can be AWS managed policies or custom policies created to match specific requirements.

2. Session Duration Specifies how long the permissions will be granted once a user assumes a role.

Use Cases​

1. Cross-Account Access Grant users in one AWS account permissions to resources in another account.

2. Application Access Allow users to access specific AWS applications with the necessary permissions.

3. Role-Based Access Control (RBAC) Align Permission Sets with job functions, creating a streamlined RBAC system across AWS accounts.

Management Practices​

1.Least Privilege Access Only include permissions necessary for the job function to minimize security risks.

2. Auditing and Review Regularly audit Permission Sets for any permissions that need to be updated or revoked to maintain security and compliance.

3. Scaling As your AWS usage grows, Permission Sets can help efficiently manage increasing numbers of users and permissions.

In AWS Identity Center, Permission Sets enable you to implement a consistent and scalable approach to access management across your AWS ecosystem, from development environments to production workloads. They serve as a cornerstone for ensuring that the right people have the right access at the right time, following security best practices:

1. The role of Permission Sets in AWS Identity Center.
2. Common challenges with Permission Sets

Understanding SCPs​

1.What are SCPs?

Service Control Policies (SCPs) are a type of policy that you can use in AWS Organizations to manage permissions in your organization. They offer central control over the maximum available permissions for all accounts in your organization, allowing you to ensure your accounts stay within your organization's access control guidelines.

2.The significance of SCPs in AWS Organizations

SCPs are like a set of guardrails that control what actions users and roles can perform in the accounts to which the SCPs are applied.

3.Common pitfalls with SCP management

They don't grant permissions but instead act as a filter for actions that are allowed by Identity and Access Management (IAM) policies and other permission settings.

Here's a breakdown of SCP's key features​

1.Organizational Control SCPs are applied across all accounts within an AWS Organization or within specific organizational units (OUs), providing a uniform policy base across multiple accounts.

2.Whitelist or Blacklist Actions SCPs can whitelist (explicitly allow) or blacklist (explicitly deny) IAM actions, regardless of the permissions granted by IAM policies.

3.Layered Enforcement Multiple SCPs can be applied to an account, providing layered security and policy enforcement. This enables more granular control over permissions for accounts that inherit multiple SCPs from various OUs.

4.Non-Overriding SCPs cannot grant permissions; they can only be used to deny permissions. Even if an IAM policy grants an action, if the SCP denies it, the action cannot be performed.

5.Boundary for IAM Permissions SCPs effectively set the maximum permissions boundary. If an action is not allowed by an SCP, no entity (users or roles) in the account can perform that action, even if they have administrative privileges.

By effectively managing SCPs, organizations can add an extra layer of security to their AWS environment, prevent unintended actions that could lead to security incidents, and maintain consistent governance and compliance across all AWS accounts.

Permission Sets vs. SCPs​

Following table provides comparison between Permission Sets and Service Control Policies (SCPs)

Upon reaching Azure, data enters the VNET, a fundamental building block providing isolation and segmentation within the Azure cloud. The VNET serves as the backbone of the cloud infrastructure, ensuring that different components within the architecture can communicate securely.

Publish to Service Bus:​

Data is then published to Azure Service Bus, a messaging service that enables disconnected communication among applications and services. Service Bus supports complex messaging patterns and ensures that data is reliably transferred between different components of the architecture.

Function App for Processing:​

Azure Functions, a serverless compute service, is utilized to process the incoming data. These functions can transform, aggregate, or perform other operations on the data before persisting it to storage or forwarding it for further analysis.

Blob Storage:​

The processed data is then stored in Azure Blob Storage, providing a scalable and secure place to maintain large volumes of unstructured data. Blob Storage supports a wide range of data types, from text and images to application logs and data backups.

Event Grid Consumption:​

Azure Event Grid, an event-driven service, detects when new objects are put into Blob Storage. It triggers subsequent processes or workflows, ensuring that data changes result in immediate and responsive actions across the architecture.

EventHub for Real-time Analytics:​

For real-time analytics, the architecture incorporates Azure Event Hub, capable of handling massive streams of data in real-time. Event Hub is ideal for scenarios requiring rapid data ingestion and processing, such as telemetry, live dashboards, or time-sensitive analytics.

Log Analytics Workspace:​

Finally, Azure Log Analytics Workspace is used for monitoring, analyzing, and visualizing the data and operations within the architecture. It provides insights into the performance and health of the services, helping to detect anomalies, understand trends, and make informed decisions based on the processed data.

Conclusion

(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.
