Mengumpulkan log Sistem Nix

Dokumen ini menjelaskan cara mengumpulkan log Sistem Nix dengan mengaktifkan penyerapan telemetri Google Cloud ke Google Security Operations dan cara kolom log dari log Sistem Nix dipetakan ke kolom Unified Data Model (UDM) Google Security Operations.

Untuk mengetahui informasi selengkapnya, lihat Penambahan data ke Google Security Operations.

Deployment standar terdiri dari log Sistem Nix yang diaktifkan untuk penyerapan ke Google Security Operations. Setiap deployment pelanggan mungkin berbeda dari representasi ini dan mungkin lebih kompleks.

Deployment berisi komponen berikut:

  • Google Cloud: Layanan dan produk Google Cloud tempat Anda mengumpulkan log.

  • Log Sistem Nix: Log Sistem Nix yang diaktifkan untuk penyerapan ke Google Security Operations.

  • Google Security Operations: Google Security Operations menyimpan dan menganalisis log dari Nix System.

Label penyerapan mengidentifikasi parser yang menormalisasi data log mentah ke format UDM terstruktur. Informasi dalam dokumen ini berlaku untuk parser dengan label transfer NIX_SYSTEM.

Jalur sumber log berikut didukung oleh parser Sistem Nix:

  • /var/log/apache2/access.log
  • /var/log/apache2/error.log
  • /var/log/nginx/access.log
  • /var/log/nginx/error.log
  • /var/log/rkhunter.log
  • /var/log/auth.log
  • /var/log/kern.log
  • /var/log/rundeck/service.log
  • /var/log/samba/log.winbindd
  • /var/log/mail.log
  • /var/log/audit/audit.log
  • /var/log/syslog
  • /var/log/openvpnas.log

Sebelum memulai

Pastikan semua sistem dalam arsitektur deployment dikonfigurasi dalam zona waktu UTC.

Mengonfigurasi Google Cloud untuk menyerap log Sistem Nix

Nix System di-deploy di Google Cloud. Anda harus mengonfigurasi Google Cloud untuk menyerap log Sistem Nix ke Google Security Operations, lihat Menyerap log Google Cloud ke Google Security Operations.

Jika Anda mengalami masalah saat menyerap log Sistem Nix, hubungi dukungan Google Security Operations.
