Memeriksa teks untuk data sensitif

Sensitive Data Protection dapat mendeteksi dan mengklasifikasikan data sensitif dalam konten teks. Dengan input teks tertentu, DLP API akan menampilkan detail tentang infoTypes yang ditemukan dalam teks, nilai likelihood, dan informasi offset.

Praktik Terbaik

Mengidentifikasi dan memprioritaskan pemindaian

Penting untuk mengidentifikasi resource Anda dan menentukan resource mana yang memiliki prioritas tertinggi untuk pemindaian. Saat baru memulai, Anda mungkin memiliki banyak data yang belum diproses yang memerlukan klasifikasi, dan tidak mungkin untuk memindainya sekaligus. Pilih data yang awalnya menimbulkan risiko tertinggi—misalnya, data yang sering diakses, dapat diakses secara luas, atau tidak diketahui.

Mengurangi latensi

Latensi dipengaruhi oleh beberapa faktor: jumlah data yang akan dipindai, repositori penyimpanan yang dipindai, serta jenis dan jumlah infoTypes yang diaktifkan.

Untuk membantu mengurangi latensi tugas, Anda dapat mencoba hal berikut:

  • Aktifkan pengambilan sampel.
  • Hindari mengaktifkan infoTypes yang tidak diperlukan. Meskipun berguna dalam skenario tertentu, beberapa infoType—termasuk PERSON_NAME, FEMALE_NAME, MALE_NAME, FIRST_NAME, LAST_NAME, DATE_OF_BIRTH, LOCATION, STREET_ADDRESS, ORGANIZATION_NAME—dapat membuat permintaan berjalan jauh lebih lambat daripada permintaan yang tidak menyertakannya.
  • Selalu tentukan infoTypes secara eksplisit. Jangan gunakan daftar infoTypes kosong.
  • Pertimbangkan untuk mengatur data yang akan diperiksa ke dalam tabel dengan baris dan kolom, jika memungkinkan, untuk mengurangi perjalanan bolak-balik jaringan.

Membatasi cakupan pemindaian pertama

Untuk hasil terbaik, batasi cakupan pemindaian pertama, bukan memindai semua data Anda. Mulai dengan beberapa permintaan. Temuan Anda akan lebih bermakna saat Anda menyesuaikan detektor yang akan diaktifkan dan aturan pengecualian yang mungkin diperlukan untuk mengurangi positif palsu. Jangan aktifkan semua infoTypes jika Anda tidak memerlukan semuanya, karena temuan positif palsu atau temuan yang tidak dapat digunakan dapat mempersulit penilaian risiko Anda. Meskipun berguna dalam skenario tertentu, beberapa infoType seperti DATE, TIME, DOMAIN_NAME, dan URL mendeteksi berbagai temuan dan mungkin tidak berguna untuk diaktifkan.

Pemindaian infrastruktur lokal, hybrid, dan multi-cloud

Jika data yang akan dipindai berada di lokal atau di luar Google Cloud, gunakan metode API content.inspect dan content.deidentify untuk memindai konten guna mengklasifikasikan temuan dan membuat pseudonim konten tanpa mempertahankan konten di luar penyimpanan lokal Anda.

Memeriksa string teks

Berikut adalah contoh JSON dan kode dalam beberapa bahasa yang menunjukkan cara menggunakan DLP API untuk memeriksa string teks guna menemukan data sensitif.
