AWS Security Hub Integration Guide

PagerDuty + AWS Security Hub Integration Benefits

• Send AWS Security Hub finding events to PagerDuty.
• Use the PagerDuty platform to manage, organize, and respond to events that are relevant to your organization.
• You can define the Event Pattern that will send AWS Security Hub finding events to PagerDuty through SNS Topics. Example JSON for the Event Pattern is available below in our CloudFormation template.
• If you would like to manually send AWS Security Hub finding events instead of automatically sending them based on an Event Pattern, you can optionally create a custom action in AWS Security Hub.

Requirements

In PagerDuty:

• This integration requires a Manager, Admin, Global Admin or Account Owner base role to configure.

In AWS Security Hub:

• If using the CloudFormation template below, you must have access to create a CloudFormation template.

How it Works

• Amazon EventBridge sends AWS Security Hub finding events to PagerDuty.
• These events then generate PagerDuty incidents and notify responders.

Version

This guide details configuration of the AWS Security Hub V1 integration.

Integration Walkthrough

In PagerDuty

There are two ways to integrate AWS Security Hub with PagerDuty:

• Integrate With Event Orchestration: Integrating with Event Orchestration may be beneficial if you want to build nested rules based on the payload coming from AWS.
• Integrate With a PagerDuty Service: Integrating with a PagerDuty service directly can be beneficial if you don’t need to route alerts from AWS to different responders based on the event payload. You can still use service-level Event Orchestration to perform actions such as alert suppression.

In the AWS Management Console

Next you will need to configure Amazon EventBridge to send AWS Security Hub events to PagerDuty. There are two ways to do this:

• Use our provided CloudFormation template
• Configure Amazon EventBridge manually

CloudFormation Template

This CloudFormation template will automatically create a new SNS Topic named SecurityHubSNSTopic. The CloudFormation template will prompt you to provide an Event Pattern for selected events to be routed to the SNS Topic target. The template will also prompt for the PagerDuty Integration URL generated in steps above.

1. Download the PagerDutyCloudFormation.template file.
2. In the AWS Management Console, search and select AWS CloudFormation in the Services search bar. Select Stacks in the left menu and then click Create stack.
3. Select Template is ready and Upload a template file.
4. Upload the PagerDutyCloudFormation.template file and then click Next.
5. Enter a Stack name and then specify the following parameters:
   • EventPatternParameter: Enter a JSON Object that represents the Event Pattern.
     • JSON Example: { "source": [ "aws.securityhub" ] }
   • PagerDutyEventsEndpoint: Enter the PagerDuty Integration URL generated in steps above.
   • Click Next.
6. On the next screen, configure stack options to your preference and then click Next.
7. On the final page, review your stack’s details and then click Create stack. The integration is now complete.

Configure Amazon EventBridge Manually

1. In the Services search bar, search and select Simple Notification Service. In the SNS dashboard left menu, select Topics and click Create Topic on the right. This topic will be used to route alerts to PagerDuty from AWS.
2. Select the Standard Topic Type.
3. Next, perform the following:
   • Name: Enter a name for your topic. You may want to name your topic after your PagerDuty service’s name.
   • Display name (optional): Enter an optional display name.
   • Click Create topic.
4. Now that your topic has been created, select Subscriptions in the left menu and click Create Subscription.
5. Perform the following:
   • Topic ARN: Select the Topic ARN of the topic you just created.
   • Protocol: Select HTTPS.
   • Endpoint: Paste your Integration URL (generated in steps above).
   • Ensure that the Enable raw message delivery checkbox is unchecked.
   • Click Create Subscription.
6. Your subscription should be automatically confirmed. Refresh the page to make sure the Status is Confirmed and not PendingConfirmation.
7. Next, search and select EventBridge from the Services search bar.
8. Select Rules from the left menu, then click Create Rule.
9. On the next screen, perform the following:
   • Name: Enter a name that can be easily identified.
   • Description (optional): Enter a description of the rule, pattern and target(s).
   • Event Bus: Select default.
   • Enable the rule on the selected event bus: Toggle to the on position.
   • Rule with an event pattern: This will automatically be preselected.
   • Click Next to continue.
10. On the next page, perform the following:
    • Event source: Select AWS events or EventBridge partner events.
    • Sample event (optional): If you would like to view sample events, you may do so in this section.
    • Event Source: Select AWS services.
    • AWS Service: Select Security Hub.
    • Event type: You may select All Events, AWS API Call via CloudTrail, Security Hub Findings - Custom Action, Security Hub Findings - Imported or Security Hub Insight Results based on your preferences.
    • Click Next to continue.
11. On the next page, perform the following:
    • Target types: Select AWS service.
    • Select a target: Search and select SNS topic.
    • Topic: Search and select the topic created in previous steps.
    • Configure other additional settings to your preference.
    • Click Next to continue.
12. On the next page, optionally add tags to your preference. Click Next to continue.
13. On the final page, review your settings and click Create Rule. If you would like to create more rules, repeat steps 7-13. Once you have finished configuring your rules, the integration is complete.

Custom Actions for Manual Notifications

If you would like to manually send AWS Security Hub findings instead of automatically sending them based on an Event Pattern, you can follow this section to configure the Custom Action button in AWS Security Hub.

1. Follow Amazon’s documentation to create a custom action, and ensure that you copy the Custom action ARN.
2. Search and select Amazon EventBridge in the Services search bar.
3. Select Rules in the left menu and click the Create Rule button.
4. On the next screen, perform the following:
   • Name: Enter a name that can be easily identified.
   • Description (optional): Enter a description of the rule, pattern and target(s).
   • Event Bus: Select default.
   • Enable the rule on the selected event bus: Toggle to the on position.
   • Rule with an event pattern: This will automatically be preselected.
   • Click Next to continue.
5. On the next page, perform the following:
   • Event source: Select Other.
   • Sample event (optional): If you would like to view sample events, you may do so in this section.
6. In the Event Pattern field, the pattern should look similar to the below example, but ensure that you replace the value CUSTOM_ACTION_ARN_HERE in the resources section value with the Custom action ARN generated above.

Example:

{
  "source": [
    "aws.securityhub"
  ],
  "detail-type": [
    "Security Hub Findings - Custom Action"
  ],
  "resources": [
    “CUSTOM_ACTION_ARN_HERE”
  ]
}

• Click Next to continue.

7. On the next page, perform the following:
   • Target types: Select AWS service.
   • Select a target: Search and select SNS topic.
   • Topic: Search and select the topic created in previous steps.
   • Configure other additional settings to your preference.
   • Click Next to continue.
8. On the next page, optionally add tags to your preference. Click Next to continue.
9. On the final page, review your settings and click Create Rule.
