NSA membagikan panduan, alat untuk mengurangi protokol enkripsi yang lemah

January 7, 2021 by Winnie the Pooh

National Security Agency (NSA) telah membagikan panduan tentang cara mendeteksi dan mengganti versi protokol Transport Layer Security (TLS) yang sudah usang dengan varian terbaru dan aman.

Badan intelijen AS juga menyoroti bahaya di balik penggunaan TLS yang sudah tidak digunakan lagi termasuk risiko paparan data sensitif dan dekripsi lalu lintas jaringan dalam serangan man-in-the-middle.

“NSA merekomendasikan bahwa hanya TLS 1.2 atau TLS 1.3 yang digunakan dan SSL 2.0, SSL 3.0, TLS 1.0, dan TLS1.1 tidak digunakan”, bunyi panduan tersebut.

Panduan NSA ditargetkan pada pemimpin keamanan siber Sistem Keamanan Nasional (NSS), Departemen Pertahanan (DoD), dan Pangkalan Industri Pertahanan (DIB), serta analis keamanan jaringan dan administrator sistem.

Namun, karena risiko yang berasal dari enkripsi lemah protokol TLS yang tidak digunakan lagi memengaruhi semua jaringan, panduan ini harus diikuti oleh semua “pemilik dan operator jaringan” yang ingin mengurangi eksposur risiko dan memperkuat sistem mereka terhadap serangan menggunakan vektor serangan ini.

Lembar Informasi Keamanan Siber yang dirilis oleh NSA [PDF] memberikan informasi ekstensif untuk semua administrator jaringan tentang versi TLS yang tidak digunakan lagi, rangkaian sandi, dan mekanisme pertukaran kunci, serta konfigurasi TLS yang direkomendasikan, strategi deteksi, dan perbaikan.
