Collect SecureLink logs

Supported in:

This document explains how to ingest SecureLink logs to Google Security Operations using Google Cloud Storage V2.

SecureLink (now Imprivata Privileged Remote Access) is a cloud-based third-party remote access platform for secure vendor and privileged access management. The SecureLink REST API provides programmatic access to session logs, authentication events, and administrative audit logs.

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 SecureLink admin portal with administrator permissions
  • A SecureLink API key with audit log read access

Create 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, securelink-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.

Generate API key

  1. Sign in to the SecureLinkadmin portal.
  2. Go to Administration > API Keys(or Administration > Integrations > API).
  3. Click Generate API Key.
  4. Enter a name for the API key (for example, Google SecOps Integration ).
  5. Select the required permissions:
    • Audit Log Read: Access to session and authentication logs
    • Session Read: Access to remote access session data
  6. Click Generate.
  7. Copy and save the following details in a secure location:

    • API Key: The generated API key value
    • Organization ID: Your SecureLink organization ID (visible in the admin portal URL or Settings page)

Determine API base URL

The SecureLink API base URL:

Environment API Base URL
Production https://api.securelink.com/v1

Test API access

  • Test your credentials before proceeding with the integration:

      # Replace with your actual credentials 
     SECURELINK_API_KEY 
     = 
     "your-api-key" 
     SECURELINK_ORG_ID 
     = 
     "your-org-id" 
     # Test API access - list recent audit logs 
    curl  
    -s  
    -X  
    GET  
     "https://api.securelink.com/v1/audit-logs?limit=1" 
      
     \ 
      
    -H  
     "Authorization: Bearer 
     ${ 
     SECURELINK_API_KEY 
     } 
     " 
      
     \ 
      
    -H  
     "X-Organization-Id: 
     ${ 
     SECURELINK_ORG_ID 
     } 
     " 
      
     \ 
      
    -H  
     "Accept: application/json" 
     
    

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 securelink-logs-collector-sa
    • Service account description: Enter Service account for Cloud Run function to collect SecureLink 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 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, securelink-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, securelink-logs-collector-sa@PROJECT_ID.iam.gserviceaccount.com )
    • Assign roles: Select Storage Object Admin
  6. Click Save.

Create 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 securelink-logs-trigger
    • Leave other settings as default
  4. Click Create.

Create 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 SecureLink 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:
