Introduction

In cloud operations, timely notifications are crucial. Whether dealing with a security incident from AWS GuardDuty, a backup failure, or any other significant event, having a streamlined process to receive and act upon alerts is essential. Traditionally, AWS users set up notifications through complex patterns involving AWS CloudTrail, EventBridge, and Lambda. However, AWS has recently introduced a new service designed to simplify this process significantly: AWS User Notifications.

In this blog, we'll walk through the benefits of this new service and how it streamlines the notification setup process compared to the traditional methods.

The Traditional Notification Setup

Historically, setting up notifications involved several AWS services:

1. CloudTrail : Events captured by CloudTrail.
2. EventBridge : Rules in EventBridge to capture and process these events.
3. Lambda : Lambda functions to parse events and send formatted notifications.
4. SNS : For sending out emails or SMS notifications.

For instance, if AWS GuardDuty detected a potential security incident, you'd need to:

• Create a rule in EventBridge to catch GuardDuty findings.
• Write Lambda functions to process these events.
• Use SNS to send notifications, often requiring custom formatting in Lambda.

While effective, this setup can be complex and involves considerable manual configuration and coding.

The New AWS User Notifications Service

AWS has introduced a more straightforward approach with the AWS User Notifications service. This new service allows you to set up notifications with minimal configuration, bypassing the need for complex EventBridge rules and Lambda functions.

Setting Up Notifications with AWS User Notifications

Here's a step-by-step guide on how to set up notifications using the new service:

1. Access AWS User Notifications

   • Go to the AWS Management Console and search for "User Notifications."
   • Open the User Notifications configuration page.

2. Create a New Notification Configuration

   • Click “Create Notification Configuration.”
   • Provide a name for the notification, such as "GuardDuty Notification."
   • Optionally, add a description.

3. Choose the Notification Source

   • Select the source of your notification. For example, choose "CloudWatch" for monitoring AWS CloudWatch events.
   • Specify the type of events you want to receive notifications for, such as "GuardDuty findings."

4. Configure Notification Details

   • Choose the AWS region you want to monitor, such as "Virginia."
   • Set up advanced filters if needed. This helps narrow down the events you want to capture, like focusing only on critical findings.
   • Decide on the aggregation period (e.g., 5 minutes, 12 hours) if you want to aggregate notifications.

5. Specify Notification Recipients

   • Enter the email addresses or other notification channels where alerts should be sent. You can use AWS's built-in options or integrate with chat channels.

6. Review and Create

   • Review your configuration.
   • Click "Create Notification Configuration" to finalize.

Comparing AWS User Notifications with Traditional Methods

Simplicity : User Notifications significantly reduce complexity by eliminating the need for multiple services like EventBridge and Lambda for basic notification setups. You configure everything in a single interface with minimal coding.

Customization : While traditional setups offer extensive customization through Lambda functions, User Notifications provide a more user-friendly approach with options for advanced filters and predefined notification formats.

Speed : The new service allows for quicker setup and deployment of notifications, making it easier to address urgent issues promptly without extensive configuration.

Use Cases

GuardDuty Alerts : Set up notifications for any security findings immediately, ensuring you can respond to potential threats without delay.

AWS Config : Receive alerts for configuration changes, focusing on non-compliant changes to avoid information overload.

Backup Failures : Get notifications for failed backup jobs to ensure data protection measures are always active.

Health Checks : Monitor AWS service health events to stay informed about the operational status of your AWS environment.

Conclusion

AWS User Notifications is a game-changer for simplifying the notification setup process. It reduces the complexity involved in configuring notifications and allows you to focus on addressing issues rather than managing notification infrastructure. By leveraging this new service, you can ensure that critical alerts are delivered promptly and efficiently.
