Overview

Use this guide to forward Cloud Secure Edge (CSE) events into your ELK (Elasticsearch, Logstash, Kibana) stack for centralized monitoring and troubleshooting. CSE emits detailed security and policy events through the CSE Events API. Using our Filebeat integration, you can:

• Collect events directly from the CSE API
• Forward events into Elasticsearch for indexing
• Visualize events in Kibana dashboards

Following the outlined steps, you will create an API key in CSE, configure Filebeat using the API key, and validate that CSE events appear in Kibana.

Prerequisites

• CSE Admin account
• Filebeat server access with permissions to install keystores and edit filebeat.yml
• Access to Elasticsearch and Kibana

Step 1: Create an API key in CSE's Command Center

1.1 In the Command Center, go to Settings > API Keys.

1.2 Add a new API Key and configure the following details:

• Name: Filebeat Integration
• Description: Used by Filebeat to collect events from CSE
• Scope: ReadOnly

Copy and save the generated API Secret securely. You will use it in Step 2.

Step 2: Store your API key secret in Filebeat

Create the key store (if it does not exist)

2.1 Log into your Filebeat server.

2.2 Run the following command in your CLI:

filebeat keystore create

Add the API key

2.3 Run the following command in your CLI:

filebeat keystore add <CSE_API_KEY>  # Replace <CSE_API_KEY> with your API key name

Enter the saved API Secret

2.4 When prompted, paste the API key Secret (saved from Step 1) in the CLI.

Step 3: Configure Filebeat

3.1 Replace the filebeat.inputs section of filebeat.yml with the following:

filebeat.inputs:
  - type: httpjson
    config_version: 2
    interval: 1m
    request.url: 'https://net.banyanops.com/api/v1/events'
    request.transforms:
      - set:
          target: header.Authorization
          value: 'Bearer ${CSE_API_KEY}' # Uses keystore variable
      - append:
          target: url.params.after
          value: '[[ .cursor.last_created_at ]]'
          default: '[[ (now (parseDuration "-5m")).UnixMilli ]]'
      - append:
          target: url.params.order
          value: 'ASC'
      - append:
          target: url.params.severity
          value: 'INFO'
      - append:
          target: url.params.limit
          value: '1000'
    response.split:
      target: body.data
    cursor:
      last_created_at:
        value: '[[ printf "%d" (add (toInt (index .last_event "created_at")) 1) ]]'
    fields_under_root: true
    fields:
      event.dataset: cse

If your organization is provisioned on the European (EUCC) Command Center, replace net.banyanops.com with eucc.console.banyanops.com in request.url.

3.2 Save your changes.

3.3 Restart Filebeat:

sudo systemctl restart filebeat

For more information on how to start Filebeat on each platform type, see Start Filebeat in the Elastic documentation.

Step 4: Verify Ingestion

4.1 Run a quick query in Elasticsearch to confirm events are flowing in:

curl -s "http://localhost:9200/filebeat-*/_search?q=event.dataset:cse&size=1&pretty"

4.2 In Kibana, search for event.dataset:cse to view and filter CSE events.

Next Steps

• Review the CSE Event Properties and Definitions for field definitions.
• Set up ELK alerts to notify when there are high-severity events.
