Enable CloudWatch Alarm Action Rule

CloudWatch Alarm Action for NIST Cybersecurity Framework (CSF) v1

Rule Description

Troubleshooting Steps (if any)

2. 1.
   Ensure that you have the necessary permissions to modify CloudWatch alarm actions. Check if you have the correct IAM role or access credentials.
4. 2.
   Verify that the alarm source (e.g., CloudTrail, VPC Flow Logs) is properly configured and sending logs and metrics data to CloudWatch.
6. 3.
   Double-check the alarm conditions and threshold settings to ensure they align with the NIST CSF v1 guidelines.
8. 4.
   If the CloudWatch alarm action fails to activate or triggers false-positive alarms, review the alarm logic and consider refining the criteria to reduce false alerts.
10. 5.
    Check the connectivity and configuration of any external services or systems that are notified or receive the CloudWatch alarm action.

Code or Configuration (if applicable)

2. 1.

   Create a CloudWatch alarm:

   • Open the Amazon CloudWatch console.
   • Select "Alarms" from the sidebar.
   • Click on "Create Alarm" to start configuring a new alarm.
   • Choose the metric you want to monitor based on the NIST CSF guidelines.
   • Define the conditions and threshold for triggering the alarm.
   • Specify how you want to be notified by configuring the "Actions" tab.
4. 2.

   Configure the alarm action:

   • In the "Actions" tab of the CloudWatch alarm configuration, select "State is ALARM."
   • Click on "Add action."
   • Choose the appropriate action based on your requirements. It could be sending notifications, invoking a Lambda function, or triggering other services.
   • Follow the prompts to complete the configuration of the selected action.
6. 3.

   Review and validate the CloudWatch alarm settings:

   • Double-check all the configurations and ensure they align with the NIST CSF v1 guidelines.
   • Test the alarm by triggering the condition that should activate it. Verify if the expected actions occur.
