Collect Skyhigh Security CASB (formerly McAfee Skyhigh CASB) logs

Supported in:

Google secops SIEM

This document explains how to ingest Skyhigh Security CASB (formerly known as McAfee Skyhigh CASB) logs to Google Security Operations using Google Cloud Storage V2.

Skyhigh Security CASB is a cloud access security broker (CASB) that provides visibility, compliance, data security, and threat protection for cloud services. It monitors user activity across SaaS, PaaS, and IaaS environments, detecting anomalies, enforcing DLP policies, and generating incident and audit logs through its REST API.

Before you begin

Make sure that 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
• A Skyhigh Security CASB tenant with administrative access
• API credentials from the Skyhigh Security console (Client ID and Client Secret)
• The Skyhigh Cloud Connector installed and configured

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, skyhigh-casb-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 Skyhigh Security CASB API credentials

Create API client credentials

1. Sign in to the Skyhigh Security console.
2. Go to Settings > Infrastructure > API Integration.
3. Click Create API Client.

4. Enter a name for the API client (for example, Google SecOps Integration).

5. Select the following scopes:

   • Incidents: Read access to CASB incident data
   • Anomalies: Read access to anomaly events
   • Audit Logs: Read access to audit trail

6. Click Create.

7. Copy and save the following details in a secure location:

   • Client ID: The generated client identifier
   • Client Secret: The generated client secret (shown only once)
   Note: The Client Secret is displayed only once at the time of creation. If you lose it, you must generate new credentials.

Get tenant base URL

1. Sign in to the Skyhigh Security console.

2. Note the base URL from the browser address bar. The format depends on your region:

   • US: https://www.myshn.net
   • EU: https://www.myshn.eu
   • SG: https://www.myshn.sg

Test API access

• Test your credentials before proceeding with the integration:

  # Replace with your actual credentials
  CLIENT_ID="your-client-id"
  CLIENT_SECRET="your-client-secret"
  BASE_URL="https://www.myshn.net"
  
  # Get OAuth 2.0 access token
  TOKEN=$(curl -s -X POST "${BASE_URL}/shnapi/rest/external/api/v1/oauth/token" \
      -H "Content-Type: application/x-www-form-urlencoded" \
      -d "grant_type=client_credentials&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}" \
      | python3 -c "import sys,json; print(json.load(sys.stdin)['access_token'])")
  
  # Test API access - list incidents
  curl -v -H "Authorization: Bearer ${TOKEN}" \
      "${BASE_URL}/shnapi/rest/external/api/v1/incidents?limit=1"

Grant IAM permissions to the Google SecOps service account

The Google SecOps service account needs Storage Object Viewer role on your GCS bucket.

1. Go to Cloud Storage > Buckets.
2. Click on your bucket name.
3. Go to the Permissions tab.

4. Click Grant access.

5. Provide the following configuration details:

   • Add principals: Paste the Google SecOps service account email
   • Assign roles: Select Storage Object Viewer

6. Click Save.

Note: If you plan to use the deletion option "Delete transferred files" or "Delete transferred files and empty directories," grant Storage Object Admin role instead of Storage Object Viewer.
