Peneliti keamanan memperingatkan kelemahan tumpukan TCP/IP dalam perangkat teknologi operasional

August 6, 2021 by Winnie the Pooh

Kerentanan keamanan dalam protokol komunikasi yang digunakan oleh sistem kontrol industri dapat memungkinkan penyerang dunia maya untuk merusak atau mengganggu layanan, serta mengakses data di jaringan.

Dijuluki INFRA:HALT, kumpulan 14 kerentanan keamanan telah dirinci oleh peneliti keamanan siber di Forescout Research Labs dan JFrog Security Research, yang memperingatkan bahwa jika dibiarkan, kelemahan tersebut dapat memungkinkan eksekusi kode jarak jauh, penolakan layanan, atau bahkan kebocoran informasi.

Semua kerentanan terkait dengan tumpukan TCP/IP – protokol komunikasi yang biasa digunakan di perangkat yang terhubung – di NicheStack, digunakan di seluruh teknologi operasional (OT) dan infrastruktur industri.

Beberapa kerentanan yang baru ditemukan berusia lebih dari 20 tahun, masalah umum dalam teknologi operasional, yang masih sering berjalan pada protokol yang dikembangkan dan diproduksi bertahun-tahun yang lalu.

Forescout telah merinci setiap kerentanan dalam posting blog – mereka terkait dengan proses paket yang salah yang memungkinkan penyerang mengirim instruksi untuk membaca atau menulis di bagian memori yang seharusnya tidak.

Semua versi NicheStack sebelum versi 4.3, termasuk NicheLite, dipengaruhi oleh kerentanan, yang telah diungkapkan ke HCC Embedded, yang mengakuisisi NicheStack pada 2016.

Bleum pasti berapa total perangkat OT yang rentan, tetapi para peneliti dapat mengidentifikasi lebih dari 6.400 perangkat yang rentan dengan menggunakan Shodan, mesin pencari Internet of Things.

Untuk membantu melindungi teknologi operasional dari segala jenis serangan siber, para peneliti di Forescout merekomendasikan agar segmentasi jaringan diterapkan, sehingga teknologi operasional yang tidak perlu terpapar ke internet tidak dapat ditemukan dari jarak jauh – dan teknologi yang tidak perlu terhubung ke internet sama sekali berada di jaringan yang terpisah dengan celah udara.
