ACL keamanan berbasis modelKetika
sebuah permintaan subjek operasi pada suatu objek dalam sebuah model
keamanan ACL berbasis sistem operasi pertama memeriksa ACL untuk entri
yang berlaku untuk memutuskan apakah operasi yang diminta berwenang. Masalah
utama dalam definisi dari setiap model keamanan ACL berbasis menentukan
bagaimana daftar kontrol akses yang diedit, yaitu mana pengguna dan
proses diberikan ACL-modifikasi akses. Model ACL dapat diterapkan untuk koleksi benda-benda serta entitas individu dalam hierarki sistem.Filesystem ACL
SOAL LATIHAN
Konfigurasikan Skema di atas agar
1. Network 10 tidak bisa diakses
oleh network 40, sedangkan yang lain bisa
2. Hot 10.5 tidak bisa mengakses
host 50.7
3. Telnet
JAWAB:
Langkah-langkah:
- Buka Program Cisco Packet Tracer
- Pilih peralatan yang akan dipakai. Agar Sesuai demean Gambar di atas saya menggunakan: 7 Unit PC, 6 Buah Switch, dan 3 Buah Router
- Atur posisi semua peralatan hingga seperti gambar di atas.
- Hubungkan PC dengan Switch menggunakan kabel straigh-Though
- Hubungkan Switch degan Router menggunakan kabel straigh-Though
- Hubungkan Router dengan Router menggunakan kabel Serial DCE (sesuaikan dengan gambar kerja)
- Atur Konfigurasi Router Seperti dibawah ini

Setting IP Configuration
pada PC dan Server seperti di bawah ini, atau bisa menggunakan IP lain
dengan catatan masih satu network
Sebelum dikonfigurasikan ACLs cek
dulu koneksi semua peralatan, untuk itu bisa gunakan perintah Ping melalui
Command Prompt
Check Koneksi PC0 dengan PC 1
Check Koneksi PC0 dengan PC 2
Check Koneksi PC0 dengan PC 3
Check Koneksi PC0 dengan PC 4
Check Koneksi PC0 dengan PC 5
Check Koneksi PC0 dengan PC 6
Check Koneksi PC0 dengan Server
Setelah dikonfigurasikan ACLs maka
Ping PC2 dengan PC0
Ping PC0 dengan PC4
