    713-19 guruh talabasi Raxmonova Mahliyoningning
    Tarmoq xavfsizligi fanidan bajargan
    LABORATORIYA ISHI №1


    1-Laboratoriya ishi
    Mavzu: Tarmoq qurilmalarida dastlabki xavfsizlik sozlamalarini o’rnatish – TELNET , SSH.

    Ishdan maqsad: Tarmoq qurilmalarida TELNET va SSH protokollarini sozlashni o’rganish.
    Ishni bajarish tartibi:
    SSH protokolini ko’rib chiqamiz.

    • Cisco Packet Tracer dasturida kerakli qurilmalarni tanlab tarmoq topologiyasini qurib olamiz.




    • SSH uchun kerak bo’ladigan buyruqlarni routerimizga kiritib olamiz.





    • SSH protokolimiz tayyor bo’ldi endi uni testlab ko’rishdan oldin har bir kompyuterga IP manzillar berib chiqamiz.




    • SSH protokolimizni tekshirib ko’ramiz.


    Protokolimiz xatosiz ishladi va shularni o’rgandim.


    2-Laboratoriya ishi
    Mavzu: Kommutatorda port xavfsizligini(port security) sozlash
    Ishni bajarish tartibi:





    • Kommutatorda port xavfsizligini sozlash uchun portlariga kerakli buyruqlarni CLI oynasi orqali yozib chiqamiz undan oldin esa kompyuterlarimizga ip manzillar berib olamiz.




    Yuqorida Secure -MAC ni dynamic aniqlash korsatilgan.

    Endi esa static aniqlashni ko’ramiz.



    Xavfsizlik buzilishiga javob berish rejimini sozlash


    Ishlatilmaydigan portlarni o’chirib qo’ysak ham bo’ladi.
    Switch>enable
    Switch#configure terminal
    Switch(config)#hostname Sw1
    Sw1(config)#interface fa0/1
    1. Portni access rejimiga o`zgartirish
    Sw1(config-if)#switchport mode access
    2. Portda port-securityni ishga tushurish
    Sw1 (config-if)#switchport port-security
    3. Secure-MAC ni dinamik aniqlashni ko`rsatish
    Sw1 (config-if)#switchport port-security mac-address sticky
    Sw1 (config-if)#exit
    4. Secure-MAC ni statik aniqlashni ko`rsatish
    Sw1(config)#interface fastEthernet 0/2
    Sw1(config-if)#switchport mode access
    Sw1(config-if)#switchport port-security
    Sw1(config-if)#switchport port-security mac-address 000B.BE9B.EE4A
    Sw1(config-if)#end
    5. Xavfsizlik buzilishigi javob berish rejimini sozlash
    Sw1(config)#interface fastEthernet 0/3
    Sw1(config-if)#switchport mode access
    Sw1(config-if)#switchport port-security
    Sw1(config-if)#switchport port-security mac-address sticky
    Sw1(config-if)#switchport port-security violation protect
    Sw1(config-if)#end
    6. Ishlatilmayotgan portlarni o`chirish
    Sw1(config)#interface range fastEthernet 0/5-24
    Sw1(config-if-range)#shutdown
