Lokal tarmoqqa haker o’zini kompyuteri va sniffer qurilmasini ulaydi va tarmoq routeri ip va mac manzilini aniqlaydi. (6.3-rasm)

6.3-rasm. Haker tarmoqda router ip va mac mazilini aniqlash jarayoni
Keyin haker o’zining komyuteri ip mac manzilini router ip va mac manziliga o’gartiradi. (6.4-rasm)

6.4-rasm.Haker kompyuterini ip va mac manzilini router ip va mac manzili etib o’zgartirishi

Va nihoyat haker qurbon kompyuteriga cheksiz ping so’rovini yuboradi. Natijada foydalanuvchi kompyuteri serverga murojati sniffer qurilmasi yordamida haker kompyuterija yuboriladi.(6.5-rasm)

6.5-rasm. Foydalanuvchi kompyuteriga ping so’rov yuborib paketlarini hakerga yo’naltirilishi.

6.6-rasm. Snifferda qurilmasida paketlar tahlili


Topshiriq.
Talaba Cisco Packet Tracer dasturini kompyuteriga o’rnatadi, local tarmoq quradi. Kompyuter va qurilamalarda ip manzil kiritadi. ARP tekshiradi. Sniffer qurilmasini local tammoqga qo’shadi va foydalanuvchi serverga yuborgan pakerlarini tutadi.
Bajargan ishlarini hisobotini tuzadi va tizimga yuklaydi.
