Intel CET

Google Chrome, Microsoft Edge mendapatkan fitur keamanan Intel ini

February 15, 2021 by Winnie the Pooh

Browser berbasis Chromium seperti Microsoft Edge dan Google Chrome akan segera mendukung fitur keamanan Intel CET untuk mencegah berbagai kerentanan.

Teknologi Control-flow Enforcement (CET) Intel adalah fitur keamanan perangkat keras yang pertama kali diperkenalkan pada tahun 2016 dan ditambahkan ke CPU Intel generasi ke-11 pada tahun 2020.

Fitur CET dirancang untuk melindungi program dari serangan Return Oriented Programming (ROP) dan Jump Oriented Programming (JOP) yang mengubah aliran normal aplikasi sehingga kode berbahaya penyerang akan dieksekusi.

“Serangan JOP atau ROP bisa sangat sulit untuk dideteksi atau dicegah karena penyerang menggunakan kode yang ada yang berjalan dari memori yang dapat dieksekusi dengan cara yang kreatif untuk mengubah perilaku program,” jelas Baiju V Patel dari Microsoft.

Kerentanan ini termasuk serangan yang melewati sandbox browser atau melakukan eksekusi kode jarak jauh saat mengunjungi situs web.

Intel CET adalah solusi berbasis perangkat keras yang memblokir upaya ini dengan memicu pengecualian saat aliran alami diubah.

Minggu ini, pimpinan penelitian kerentanan Microsoft Edge Johnathan Norman mentweet bahwa Microsoft Edge 90 akan mendukung fitur Intel CET dalam proses non-perender.

Fitur keamanan ini tampaknya tidak khusus untuk Microsoft Edge tetapi akan hadir di semua browser Chromium, termasuk Google Chrome, Brave, dan Opera.
