Step 7: Enable Additional Load Balancer Options (Optional)

Add a security layer and enable other Load Balancer options

In this tutorial step, for the Application Load Balancer (ALB) you created in Step 6, you will:

  • Enable access logging to monitor HTTP message details and record incoming traffic data. Access logs are crucial for analyzing traffic patterns and identifying potential threats, but they are not enabled by default. You must manually activate them in the Load Balancer settings.

  • Protect against requests that contain invalid headers.

Estimated time to complete Step 7: 5 minutes.

Prerequisites

Before securing a Load Balancer, verify that you accomplished the tasks in the previous tutorial steps. Using the DuploCloud Portal, confirm that:

Securing the Load Balancer

  1. In the Tenant list box, select the dev01 Tenant.

  2. In the DuploCloud Portal, navigate to Kubernetes -> Services.

  3. From the NAME column, select the Service (demo-service).

  4. Select the Load Balancers tab.

  5. In the Other Settings card, click Edit. The Other Load Balancer Settings pane displays.

  6. Select the Enable Access Logs and Drop Invalid Headers options.

  7. Accept the remaining default settings and click Save. The settings are updated.

Checking Your Work

  1. In the Tenant list box, select the dev01 Tenant.

  2. In the DuploCloud Portal, navigate to Kubernetes -> Services.

  3. From the NAME column, select the Service (demo-service).

  4. Select the Load Balancers tab.

  5. Verify that the Other Settings card contains the selections you made above for:

  • Web ACL - None

  • HTTP to HTTPS Redirect - False

  • Enable Access Logs - True

  • Drop Invalid Headers - True

Enabling access logs enhances the security and monitoring capabilities of your Load Balancer and provides insights into the traffic accessing your application, for a more robust security posture.
