Mengumpulkan log FortiCNAPP (sebelumnya Lacework)

Didukung di:

Dokumen ini menjelaskan cara menyerap log FortiCNAPP (sebelumnya dikenal sebagai Lacework) ke Google Security Operations menggunakan Google Cloud Storage V2.

FortiCNAPP adalah platform perlindungan aplikasi berbasis cloud (CNAPP) yang menyediakan pengelolaan postur keamanan cloud, perlindungan workload, dan deteksi ancaman di seluruh lingkungan multi-cloud. Lacework menghasilkan pemberitahuan, temuan kepatuhan, dan log audit yang dapat dikumpulkan melalui Lacework REST API.

Sebelum memulai

Pastikan Anda memiliki prasyarat berikut:

  • Instance Google SecOps
  • Project GCP dengan Cloud Storage API diaktifkan
  • Izin untuk membuat dan mengelola bucket GCS
  • Izin untuk mengelola kebijakan IAM di bucket GCS
  • Izin untuk membuat layanan Cloud Run, topik Pub/Sub, dan tugas Cloud Scheduler
  • Akses istimewa ke konsol FortiCNAPP (sebelumnya Lacework) dengan izin admin
  • Akun Lacework dengan akses kunci API diaktifkan

Membuat bucket Google Cloud Storage

  1. Buka Konsol Google Cloud.
  2. Pilih project Anda atau buat project baru.
  3. Di menu navigasi, buka Cloud Storage > Buckets.

  4. Klik Create bucket.

  5. Berikan detail konfigurasi berikut:

    Setelan Nilai
    Beri nama bucket Anda Masukkan nama yang unik secara global (misalnya, lacework-logs)
    Location type Pilih berdasarkan kebutuhan Anda (Region, Dual-region, Multi-region)
    Location Pilih lokasi (misalnya, us-central1)
    Kelas penyimpanan Standar (direkomendasikan untuk log yang sering diakses)
    Access control Seragam (direkomendasikan)
    Alat perlindungan Opsional: Aktifkan pembuatan versi objek atau kebijakan retensi

  6. Klik Create.

Mengumpulkan kredensial API FortiCNAPP (sebelumnya Lacework)

Buat kunci API

  1. Login ke konsol Lacework Anda.
  2. Buka Settings > Configuration > API Keys.
  3. Klik + Tambahkan Baru.
  4. Masukkan nama untuk kunci API (misalnya, Google SecOps Integration).
  5. Masukkan deskripsi secara opsional.

  6. Klik Simpan.

  7. Salin dan simpan detail berikut di tempat yang aman:

    • ID Kunci: ID kunci API yang dibuat
    • Secret: Rahasia API yang dibuat (hanya ditampilkan sekali)

  8. Catat URL akun Lacework Anda dari kolom URL browser.

    • Format: https://<ACCOUNT>.lacework.net
    • Contoh: Jika URL konsol Lacework Anda adalah https://acme.lacework.net, nama akun Anda adalah acme

Verifikasi izin

Untuk memverifikasi bahwa akun memiliki izin yang diperlukan:

  1. Login ke konsol Lacework.
  2. Buka Settings > Configuration > API Keys.
  3. Jika Anda dapat melihat halaman Kunci API dan membuat kunci, berarti Anda memiliki izin yang diperlukan.
  4. Jika Anda tidak dapat melihat opsi ini, hubungi administrator Anda untuk memberikan akses tingkat admin.

Menguji akses API

  • Uji kredensial Anda sebelum melanjutkan integrasi:

    # Replace with your actual credentials
LW_ACCOUNT="your-account-name"
LW_KEY_ID="your-api-key-id"
LW_SECRET="your-api-secret"

# Get a temporary access token
TOKEN=$(curl -s -X POST "https://${LW_ACCOUNT}.lacework.net/api/v2/access/tokens" \
    -H "X-LW-UAKS: ${LW_SECRET}" \
    -H "Content-Type: application/json" \
    -d "{\"keyId\": \"${LW_KEY_ID}\", \"expiryTime\": 3600}" | python3 -c "import sys,json; print(json.load(sys.stdin).get('token',''))")

# Test API access - list alerts
curl -v -H "Authorization: Bearer ${TOKEN}" \
    "https://${LW_ACCOUNT}.lacework.net/api/v2/Alerts?startTime=$(date -u -v-1d +%Y-%m-%dT%H:%M:%SZ)&endTime=$(date -u +%Y-%m-%dT%H:%M:%SZ)"

Buat akun layanan untuk Cloud Run Function

Fungsi Cloud Run memerlukan akun layanan dengan izin untuk menulis ke bucket GCS dan dipanggil oleh Pub/Sub.

Membuat akun layanan

  1. Di GCP Console, buka IAM & Admin > Service Accounts.

  2. Klik Create Service Account.

  3. Berikan detail konfigurasi berikut:

    • Nama akun layanan: Masukkan lacework-logs-collector-sa
    • Deskripsi akun layanan: Masukkan Service account for Cloud Run function to collect FortiCNAPP (formerly Lacework) logs

  4. Klik Create and Continue.

  5. Di bagian Grant this service account access to project, tambahkan peran berikut:

    1. Klik Pilih peran.
    2. Telusuri dan pilih Storage Object Admin.
    3. Klik + Add another role.
    4. Telusuri dan pilih Cloud Run Invoker.
    5. Klik + Add another role.
    6. Telusuri dan pilih Cloud Functions Invoker.

  6. Klik Lanjutkan.

  7. Klik Done.

Peran ini diperlukan untuk:

  • Storage Object Admin: Menulis log ke bucket GCS dan mengelola file status
  • Cloud Run Invoker: Mengizinkan Pub/Sub memanggil fungsi
  • Cloud Functions Invoker: Mengizinkan pemanggilan fungsi

Memberikan izin IAM pada bucket GCS

Beri akun layanan izin tulis di bucket GCS:

  1. Buka Cloud Storage > Buckets.
  2. Klik nama bucket Anda (misalnya, lacework-logs).
  3. Buka tab Izin.

  4. Klik Grant access.

  5. Berikan detail konfigurasi berikut:

    • Tambahkan prinsipal: Masukkan email akun layanan (misalnya, lacework-logs-collector-sa@PROJECT_ID.iam.gserviceaccount.com)
    • Tetapkan peran: Pilih Storage Object Admin

  6. Klik Simpan.

Membuat topik Pub/Sub

Buat topik Pub/Sub yang akan dipublikasikan oleh Cloud Scheduler dan akan dilanggan oleh fungsi Cloud Run.

  1. Di Konsol GCP, buka Pub/Sub > Topics.

  2. Klik Create topic.

  3. Berikan detail konfigurasi berikut:

    • ID Topik: Masukkan lacework-logs-trigger
