Ringkasan

Log audit diperiksa untuk mendeteksi penghapusan kumpulan penyimpanan. Kumpulan penyimpanan mengaitkan bucket Cloud Storage dengan Backup and DR.

Event Threat Detection adalah sumber temuan ini.

Cara merespons

Untuk merespons temuan ini, lakukan hal berikut:

Langkah 1: Tinjau detail temuan

  1. Buka temuan Impact: Google Cloud Backup and DR delete storage pool, seperti yang dijelaskan dalam Meninjau temuan. Panel detail untuk temuan akan terbuka di tab Ringkasan.
  2. Di tab Ringkasan, tinjau informasi di bagian berikut:
    • Apa yang terdeteksi, terutama kolom berikut:
      • Nama pool penyimpanan: nama untuk bucket penyimpanan tempat cadangan disimpan
      • Principal subject: pengguna yang berhasil menjalankan tindakan
    • Affected resource
      • Nama tampilan resource: project tempat kumpulan penyimpanan dihapus
    • Link Related, terutama kolom berikut:
      • Metode MITRE ATTACK: tautan ke dokumentasi MITRE ATT&CK
      • Logging URI: link untuk membuka Logs Explorer

Langkah 2: Teliti metode serangan dan respons

Hubungi pemilik akun layanan di kolom Principal email. Konfirmasi apakah pemilik yang sah melakukan tindakan tersebut.

Langkah 3: Terapkan respons Anda

Rencana respons berikut mungkin sesuai untuk temuan ini, tetapi juga dapat memengaruhi operasi. Evaluasi dengan cermat informasi yang Anda kumpulkan dalam penyelidikan untuk menentukan cara terbaik dalam menyelesaikan temuan.

  1. Di project tempat tindakan dilakukan, buka konsol pengelolaan.
  2. Di tab Manage, pilih Storage Pools untuk melihat daftar semua kumpulan penyimpanan.
  3. Tinjau asosiasi kumpulan penyimpanan dengan Backup Appliances.
  4. Jika appliance aktif tidak memiliki kumpulan penyimpanan terkait, pilih Add OnVault Pool untuk menambahkannya kembali.
