    Korporativ tarmoq qanday ishlaydi
    Korporativ tarmoq ish stoli kompyuterlari, serverlar va boshqa qurilmalar o'rtasida ma'lumotlarni uzatishni boshqaradigan yuqori tezlikdagi kalitlar va routerlar yordamida ishlaydi. Tarmoq kalitlari va marshrutizatorlari optik tolali va keng polosali ulanishlarga jismonan ulangan va ko'pincha qurilmalarda proshivkaning bir qismi sifatida xavfsizlik devori dasturlarini ishga tushirish uchun ishlatiladi. Administratorlar va tarmoq ta'minotchilari Ethernet kabellari yoki Wi-Fi yordamida ish stoli kompyuterlarini ofislar, o'quv muassasalari yoki fabrikalardagi routerlarga ulaydi. Har bir oxirgi qurilmaga tarmoqdagi identifikatsiya raqami beriladi. Hisob ma'lumotlari tekshirilgandan so'ng xodimlar tizimga kirishlari uchun siz foydalanuvchi hisoblarini ham yaratishingiz kerak. Tizim ma'murlari tarmoq uchun xavfsizlik devori qoidalarini va Internetga kirish cheklovlarini tashkiliy boshqaruv talablariga muvofiq sozlaydi.
    Korporativ LANdan foydalanib, siz bir vaqtning o'zida bir nechta foydalanuvchi uchun maxsus litsenziya shartnomalari bo'yicha dasturiy ta'minotni ishga tushirishingiz yoki printerlarni ulashishingiz mumkin. Xususiy ma'lumotlar markazi ma'lumotlar bazasi ilovalari va boshqa xodimlar dasturiy ta'minotiga xizmat ko'rsatuvchi LAN tarmog'ida joylashgan bo'lishi mumkin, bu erda veb-serverlar fayllarni uzatish uchun HTTP/S va TCP/IP standartlaridan foydalangan holda jamoat resurslariga kirishadi. LAN serveriga kirish odatda faqat vakolatli xodimlar uchun cheklangan. So'nggi 10 yil ichida korporatsiyalar korporativ xavfsizlik siyosatiga integratsiya qilinishi kerak bo'lgan AT xizmatlari uchun provayderlar va ommaviy bulut platformalariga tobora ko'proq murojaat qilmoqdalar. Endi xavfsizlik devorlari VPN orqali xavfsiz, shifrlangan tarmoq ulanishlaridan foydalangan holda uzoq muhitlarda joylashtirilgan SaaS ilovalarini qo'llab-quvvatlash uchun sozlanishi kerak.


    Laboratoriya ishining amaliy qismi
    8-sonli laboratoriya ishi loyihasini ochamiz.


    Korporativ tarmoq loyihasi.


    Tugallangan laboratoriya ishlari asosida loyihalashtiriladigan korporativ tarmoq turli shaharlarda joylashgan 2 ta kichik tarmoq, bitta tashkilotni oʻz ichiga oladi. Birinchi kichik tarmoqni 1-filialga ajratamiz, ikkinchi tarmoqni 2-tarmoqqa ajratamiz.

    Biz ping orqali malumotlar almashinish jarayonlarini tekshirdik.
