    Collect Cequence Bot Defense logs

    Supported in:

    This document explains how to ingest Cequence Bot Defense logs to Google Security Operations using Google Cloud Storage V2.

    Cequence Bot Defense is an API security and bot management platform that detects and mitigates automated threats targeting web applications and APIs. It generates logs about bot detection events, policy violations, and traffic analysis through the Cequence Unified API Protection (UAP) REST API.

    Before you begin

    Make sure you have the following prerequisites:

    • A Google SecOps instance
    • A GCP project with Cloud Storage API enabled
    • Permissions to create and manage GCS buckets
    • Permissions to manage IAM policies on GCS buckets
    • Permissions to create Cloud Run services, Pub/Sub topics, and Cloud Scheduler jobs
    • Privileged access to the Cequence UAP management console with administrator permissions
    • A Cequence API key with access to the Bot Defense events API

    Create a Google Cloud Storage bucket

    1. Go to the Google Cloud Console .
    2. Select your project or create a new one.
    3. In the navigation menu, go to Cloud Storage > Buckets.
    4. Click Create bucket.

    5. Provide the following configuration details:

      Setting Value
      Name your bucket Enter a globally unique name (for example, cequence-bot-defense-logs )
      Location type Choose based on your needs (Region, Dual-region, Multi-region)
      Location Select the location (for example, us-central1 )
      Storage class Standard (recommended for frequently accessed logs)
      Access control Uniform (recommended)
      Protection tools Optional: Enable object versioning or retention policy

    6. Click Create.

    Collect Cequence Bot Defense API credentials

    Create an API key

    1. Sign in to the Cequence UAP management console.
    2. Navigate to Settings > API Keys(or Administration > API Management).
    3. Click Create API Keyor Generate New Key.
    4. Enter a name for the API key (for example, Google Security Operations Integration ).
    5. Assign the required permissions:
      • Readaccess to Bot Defense events
      • Readaccess to attack data

    6. Copy and save the API Keyvalue in a secure location.

    Determine the API base URL

    The Cequence API base URL is tenant-specific:

    Format Example
    Tenant URL https://your-tenant.cequence.ai/api/v2

    Verify API access

    • Test your credentials before proceeding with the integration:

        # Replace with your actual credentials 
 CEQUENCE_API_KEY 
 = 
 "your-api-key" 
 CEQUENCE_BASE 
 = 
 "https://your-tenant.cequence.ai/api/v2" 
curl  
-s  
-H  
 "X-API-Key: 
 ${ 
 CEQUENCE_API_KEY 
 } 
 " 
  
 \ 
  
 " 
 ${ 
 CEQUENCE_BASE 
 } 
 /botdefense/events?limit=1" 
  
 | 
  
head  
-c  
 500

    The Cloud Run function needs a service account with permissions to write to GCS bucket and be invoked by Pub/Sub.

    1. In the GCP Console, go to IAM & Admin > Service Accounts.
    2. Click Create Service Account.
    3. Provide the following configuration details:
      • Service account name: Enter cequence-logs-collector-sa
      • Service account description: Enter Service account for Cloud Run function to collect Cequence Bot Defense logs
    4. Click Create and Continue.
    5. In the Grant this service account access to projectsection, add the following roles:
      1. Click Select a role.
      2. Search for and select Storage Object Admin.
      3. Click + Add another role.
      4. Search for and select Cloud Run Invoker.
      5. Click + Add another role.
      6. Search for and select Cloud Functions Invoker.
    6. Click Continue.
    7. Click Done.

    These roles are required for:

    • Storage Object Admin: Write logs to GCS bucket and manage state files
    • Cloud Run Invoker: Allow Pub/Sub to invoke the function
    • Cloud Functions Invoker: Allow function invocation

    Grant IAM permissions on a GCS bucket

    Grant the service account write permissions on the GCS bucket:

    1. Go to Cloud Storage > Buckets.
    2. Click on your bucket name (for example, cequence-bot-defense-logs ).
    3. Go to the Permissionstab.
    4. Click Grant access.
    5. Provide the following configuration details:
      • Add principals: Enter the service account email (for example, cequence-logs-collector-sa@PROJECT_ID.iam.gserviceaccount.com )
      • Assign roles: Select Storage Object Admin
    6. Click Save.

    Create a Pub/Sub topic

    Create a Pub/Sub topic that Cloud Scheduler will publish to and the Cloud Run function will subscribe to.

    1. In the GCP Console, go to Pub/Sub > Topics.
    2. Click Create topic.
    3. Provide the following configuration details:
      • Topic ID: Enter cequence-logs-trigger
      • Leave other settings as default
    4. Click Create.

    Create a Cloud Run function to collect logs

    The Cloud Run function will be triggered by Pub/Sub messages from Cloud Scheduler to fetch logs from the Cequence UAP REST API and write them to GCS.

    1. In the GCP Console, go to Cloud Run.
    2. Click Create service.
    3. Select Function(use an inline editor to create a function).

    4. In the Configuresection, provide the following configuration details:

      Setting Value
      Service name cequence-logs-collector
      Region Select region matching your GCS bucket (for example, us-central1 )
      Runtime Select Python 3.12or later

    5. In the Trigger (optional)section:

      1. Click + Add trigger.
      2. Select Cloud Pub/Sub.
      3. In Select a Cloud Pub/Sub topic, choose the topic cequence-logs-trigger .
      4. Click Save.

    6. In the Authenticationsection:

      1. Select Require authentication.
      2. Check Identity and Access Management (IAM).

    7. Scroll down and expand Containers, Networking, Security.

    8. Go to the Securitytab:

      • Service account: Select the service account cequence-logs-collector-sa .

    9. Go to the Containerstab:

      1. Click Variables & Secrets.
      2. Click + Add variablefor each environment variable:
      Variable Name Example Value Description

      		your-api-key Cequence API key
      MAX_RECORDS
      		5000 Max records per run
      PAGE_SIZE
      		1000 Records per page

    Create a Cloud Scheduler job

    Cloud Scheduler will publish messages to the Pub/Sub topic at regular intervals, triggering the Cloud Run function.

    1. In the GCP Console, go to Cloud Scheduler.
    2. Click Create Job.

    3. Provide the following configuration details:

      Setting Value
      Name cequence-logs-collector-hourly
      Region Select same region as Cloud Run function
      Frequency 0 * * * * (every hour, on the hour)
      Timezone Select timezone (UTC recommended)
      Target type Pub/Sub
      Topic Select the topic cequence-logs-trigger
      Message body {} (empty JSON object)

    4. Click Create.

    Schedule frequency options

    Choose frequency based on log volume and latency requirements:

    Frequency Cron Expression Use Case
    Every 5 minutes
    		 */5 * * * * High-volume, low-latency
    Every 15 minutes
    		 */15 * * * * Medium volume
    Every hour
    		 0 * * * * Standard (recommended)
    Every 6 hours
    		 0 */6 * * * Low volume, batch processing
    Daily
    		 0 0 * * * Historical data collection

    Test the integration

    1. In the Cloud Schedulerconsole, find your job.
