Google Chrome untuk Linux mendapatkan DNS-over-HTTPS, tetapi ada maksud lain

April 1, 2021 by Winnie the Pooh

Pengembang Google Chrome telah mengumumkan rencana untuk meluncurkan dukungan DNS-over-HTTPS (DoH) ke browser web Chrome untuk Linux.

Sementara versi pasti dari Chrome untuk Linux yang akan keluar dengan dukungan DoH belum diumumkan, proyek Chromium mengharapkan M91 atau M92 untuk memuat fitur tersebut.

DoH mengenkripsi lalu lintas DNS biasa melalui HTTPS dengan permintaan dan tanggapan DNS yang dikirim melalui port 443, membuat lalu lintas berbaur langsung dengan lalu lintas biasa ke situs web HTTPS.

Ini tidak hanya menyediakan enkripsi end-to-end kepada pengguna tetapi juga privasi yang diperpanjang, karena sekarang lalu lintas DNS mereka tidak dapat dengan mudah dicegat oleh administrator jaringan.

“Chrome tidak pernah mendukung DoH di Linux karena itu akan membutuhkan klien DNS bawaan Chrome, yang saat ini dinonaktifkan di Linux,” membaca dokumen desain untuk fitur yang akan datang ini.

Chrome selalu mendelegasikan resolusi host di Linux ke resolver DNS sistem operasi, kecuali dengan pengaturan kebijakan non-standar.

Selain itu, klien DNS bawaan browser web telah dibiarkan nonaktif pada implementasi Linux selama bertahun-tahun karena Chrome tidak menerima konfigurasi DNS Linux lanjutan melalui file Linux Name Configuration Switch (nsswitch.conf), jelas pengembang Chromium Eric Orth dalam dokumen tersebut.

Agar pemecah DNS bawaan Chrome berfungsi lancar dengan Linux, Chrome perlu membaca dan mengurai konfigurasi DNS Linux agar dapat menonaktifkan DoH pada konfigurasi yang tidak didukung.

Secara khusus, dukungan harus ada di dalamnya sehingga Chrome dapat menerima pengaturan konfigurasi resolusi host lanjutan yang ditentukan dalam file nsswitch.conf.

Jika tidak demikian, Chrome tidak akan beralih ke DoH atau menggunakan resolver DNS bawaan kecuali pengguna secara eksplisit memilih server DoH di setelan Chrome.

Selain itu, meskipun DoH membawa serta keamanan dan privasi tambahan untuk pengguna, ada beberapa peringatan kecil dengan implementasi DoH, apa pun platformnya.
