Tarmoq — bu oddiy kabel va switchlar emas.
U go‘yoki o‘rgimchak to‘ri
🕸
Siz yolg‘iz emassiz.
Siz boshqa tashkilotlar, servislar, cloud platformalar va integratsiya qilingan tizimlar bilan bog‘langansiz
Endi tasavvur qiling…
Siz bilan integratsiya qilgan tashkilotga hujum bo‘ldi.
Ularning tizimi buzildi.
Va siz bu haqida xabar topdingiz.
Birinchi savol:
Bu sizga ta’sir qilganmi?
Ikkinchi savol:
Sizning tarmog'igiz qanchalik mustahkam?
Uchinchi savol:
Sizda monitoring bormi yoki faqat internet ishlayotganiga qarab xotirjam yuribsizmi?
😁
Kiberxavfsizlik — bu faqat o‘z tizimingizni himoya qilish emas.
Bu siz bog‘langan butun ekotizimni tushunish demak.
Va mening reaksiyam

Cisco ACL’larni boshqarishni osonlashtirish uchun object-group dan foydalaning!
👨💻
Bir nechta subnet yoki host’larni bitta nom ostida jamlash mumkin
👨💻
ACL’larda bir qatorda reference qilish → oson update va scalable
👨💻
Xatolar kamayadi, tarmoq policies toza va modul bo‘ladi
👨💻
Katta tarmoqlarda ACL’larni boshqarish endi oson va chiroyli!
vaziyatga qarab boshqa joylarda ham bog'lab ishlatsa bo'ladi

ip virtual-reassembly
bu buyruq IP fragmentlarni qayta yig‘adi (reassembly) va shu orqali NAT/ACL/Firewall’ni aldab o‘tish hujumlaridan himoya qiladi.
IP paketlar fragmentlarga bo‘linib kelishi mumkin (masalan MTU kichik bo‘lsa).
Hujumchilar shundan foydalanib:
ACL’ni fragmentlab chetlab o‘tish
NAT’ni buzish
Firewall’ni aldatish mumkin.
ip virtual-reassembly esa:
Kirayotgan fragmentlarni vaqtincha buffer’da yig‘adi
To‘liq paket bo‘lgandan keyin
ACL, NAT, crypto map kabi tekshiruvlarga yuboradi
ISR routerlarda:
NAT
CBAC (ip inspect)
Zone-Based Firewall
Crypto (IPsec)
bilan birga juda muhim.
Aniq bilaman bunaqa malumot kurslarda o'rgatishmaydi
