Tanya jawab
Seberapa sering papan peringkat SSL diperbarui?
Domain yang dipantau dipindai setiap hari; papan peringkat 20 ribu teratas memperbarui snapshot penuh setiap Minggu.
Bagaimana nilai SSL dihitung?
Versi protokol, kekuatan cipher, validitas sertifikat, HSTS, dan OCSP stapling dibobot menjadi skor 0–100, lalu dipetakan ke nilai A+ hingga F.
Apa arti nilai SSL A+?
Konfigurasi TLS nyaris sempurna: TLS 1.3 aktif, cipher suite kuat, forward secrecy penuh (PFS), dan HSTS diterapkan dengan benar.
Metodologi
CertH menilai setiap domain via TLS handshake murni (tanpa akses server): validitas sertifikat, kekuatan kunci, versi protokol, HSTS, dan OCSP stapling dibobot menjadi skor 0-100 yang dipetakan ke enam nilai dari A+ hingga F. Snapshot harian membentuk tren kesehatan yang bisa diaudit.
Apa itu nilai SSL?
Nilai SSL (A+ hingga F) menilai konfigurasi TLS situs secara keseluruhan: versi protokol, kekuatan cipher, validitas dan rantai kepercayaan sertifikat, HSTS, dan OCSP stapling. Semakin tinggi nilainya, semakin kuat ketahanan terhadap serangan man-in-the-middle dan kebocoran data.
Mengapa memantau kesehatan sertifikat dari waktu ke waktu?
Sertifikat kedaluwarsa, pergantian CA, dan kemunduran konfigurasi bisa menurunkan nilai tanpa disadari. Snapshot harian CertH mencatat perubahan itu agar Anda melihat risiko sebelum terjadi kegagalan, dengan riwayat yang dapat diaudit.
