Tugas Keamanan Sistem Lanjut (Studi Kasus : ITB dan Detik)

Diambil dari tulisan yang penulis post di blog pribadi dalam rangka tugas salah satu mata kuliah semester kemarin.

Berikut hasil dokumentasi tugas mata kuliah Keamanan Sistem Lanjut yang diajarkan oleh Bapak Budi Rahardjo dan URLnya telah diposting di Blended Learning ITB.

Untuk materi kuliah silahkan ambil di sini atau di sini.

Untuk eksperimen tugas ini seperti biasa menggunakan sistem operasi Linux Ubuntu 9.04 (satu – satunya OS yang saya miliki dan saya install di di laptop Toshiba), koneksi internet dan intranet ITB, serta materi kuliah dan buku catatan perkuliahan ini.

Soal untuk tugas ini (diambil dariBlended Learning ITB) :
1.) Cari pemilik domain dari data whois untuk itb.ac.id dan sebuah domain lain (yang disebutkan di kelas : www.detik.com)
2.) Cari name server (NS) dari domain itb.ac.id dan domain lain tersebut
3.) Cari mx record (MX) dari domain itb.ac.id dan domain lain tersebut
4.) Lakukan zone transfer terhadap domain itb.ac.id dan hitung jumlah 4th level domain. (Catatan: coba buat program / skrip yang bisa melakukan hal tersebut.)
5.) Dapatkan Anda melakukan zone transfer terhadap domain lain tersebut?

Untuk menjawab soal pertama, saya membuka terminal dan mengetikkan command whois.
Hasilnya seperti ini :
ITB :

putu-shinoda@my-machine:~$ whois itb.ac.id
% This is the register.net.id Whois server.
% For more detailed information, please check the website

Domain servers in listed order:

NS.DETIK.NET.ID
NS1.DETIK.NET.ID

Ini penampakannya gan

Dari kedua hasil tersebut, ada banyak info yang diperoleh : kapan domain dibuat, kapan berakhirnya, siapa pengurusnya, alamat, instansi, dan lain – lain. Attacker kerap menggunakan cara ini dalam rangka mengumpulkan info target sebanyak – banyaknya. Selain menggunakan terminal, dapat juga dilakukan via website di http://who.is/

Untuk soal kedua, cukup gunakan command nslookup dan host di terminal.
Hasilnya sebagai berikut :
ITB :

putu-shinoda@my-machine:~$ nslookup itb.ac.id

Soal keempat mengenai zona transfer.
Jaringan yang tangguh dan (paham) mengenai keamanan, memang seharusnya melakukan zona transfer dari dalam (intranet) saja dan tidak memperbolehkan dari luar (internet). Demikian juga untuk ITB dan Detik, saat ane coba dari luar (internet), keduanya sama – sama merefused. Namun saat saya mencoba melakukan zona transfer dan menghitung ada berapa domain tingkat 4 yang dimiliki oleh ITB via intranet ITB, hal ini bisa dilakukan dengan baik. Saya menggunakan IP private di jaringan internal perpustakaan umum ITB wireless via DHCP.

Adapun domain tingkat 4 misalkan paume.itb.ac.id. Berdasarkan hasil percobaan dengan menggunakan command host -l, diperoleh 497 buah domain tingkat 4 di jaringan ITB. Berikut listnya :

(dilakukan dari jaringan lokal, dari luar/internet akan direfused)
