Bugun biz 25 nafar davlat tashqilotlari adminlariga gibrit shaklidagi Cisco CCNA kursimizga start berdik
Dars oxrida bugungi mavzular boycha kichik bir test o’tkazdik va 1/2/3 o’rinlarga sovg’alar topshirdik

🔐 Kecha SOC yo'nalishida juda foydali treningda bo'ldim!
Fortinet mutaxassislari bilan birga 3 ta muhim mavzuni chuqur ko'rib chiqdik:
1️⃣ SOC & Zero Trust
ZTNA va EMS yordamida masofadan ulangan qurilmalarni to'liq nazorat qilish va ko'rish mumkinligini o'rgandim. "Hech kimga ishonma, hamma narsani tekshir" — Zero Trust tamoyili amalda qanday ishlashini ko'rdim.
2️⃣ SOC Hunt & Detect
FortiRecon, NDR va Deception texnologiyalari yordamida yashirin tahdidlarni qanday qidirib topish mumkinligini o'rgandim. Ayniqsa Deception — hujumchini aldab, uni tuzog'ga tushirish texnikasi — juda qiziqarli bo'ldi.
3️⃣ SOC Automation
FortiSIEM + FortiSOAR birikmasi qanday qilib SOC jamoasining qo'lda bajaradigan ishini avtomatlashtirishi va vaqtni tejashini ko'rdim.
Har bir prezentatsiya real holatlar va amaliy misollar bilan to'ldirilgan edi. Bilimlarni mustahkamlash uchun ajoyib format! 💪

Cisco CCNA imtihonini v1.1 dan v2.0 ga yangilamoqda va o'zgarishlarga e'tibor berishga arziydi.
Men ikkala loyihani ham ko'rib chiqdim va bir nechta narsalar darhol ajralib turdi. Yangi versiyada Agentic AI, OSPFv3, DNS va yanada rivojlangan muammolarni bartaraf etish kabi mavzular keltirilgan, bu sanoat tez rivojlanayotgani va sertifikatlash ham shunga mos ravishda harakat qilayotganining aniq belgisidir.
O'zgarishlar:
📘 CCNA v1.1 (Current)
• Network Fundamentals — 20%
• Network Access — 20%
• IP Connectivity — 25%
• IP Services — 10%
• Security Fundamentals — 15%
• Automation & Programmability — 10%
📗 CCNA v2.0 (Upcoming)
• Network Infrastructure & Connectivity — 25%
• Switching & Network Access — 25%
• IP Routing — 20%
• Network Services & Security — 20%
• AI & Network Operations — 10%

✅ Security Profile qachon kerak?
Faqat "Allow" (ruxsat berish) action bilan sozlangan Security Policy qoidalarida
Ruxsat berilgan trafikni qo'shimcha tekshirish uchun ishlatiladi
❌ Security Profile qachon kerak emas?
"Deny" (bloklash) action bilan sozlangan qoidalarda
Sababi: trafik allaqachon bloklangan, qo'shimcha tekshiruv shart emas

FortiGate Security Profiles
Packet Allowed by Policy
Paketlar avval Security Policy tomonidan o'tkazilishga ruxsat beriladi

🚀 GenAI network konfiguratsiyalarni soniyalar ichida yaratishi mumkin.
Lekin production outage, noto‘g‘ri route filtering yoki failover muammolari yuz bersa — javobgarlik hali ham engineer zimmasida qoladi.
Farq shunda: bu automation va haqiqiy engineering o‘rtasidagi tafovut.
AI network engineer’larni almashtirmaydi.
Aksincha, AI va zamonaviy tool’lardan foydalana oladigan engineer’lar boshqalardan ancha oldinda bo‘ladi.
Networking o‘lyaptimi? Yo‘q.
U evolyutsiya qilyapti.
Bugungi asosiy savol:
❌ “AI network engineer’larni almashtiradimi?”
✅ “Siz yangi texnologiyalarni yetarlicha tez o‘rganyapsizmi?”

Har bir tarmoq tashqaridan oddiy ko'rinadi, muhandislar o'z protokoli nima uchun eng yaxshi ekanligini tushuntirishni boshlamaguncha.
Har bir barqaror dizayn ortida son-sanoqsiz munozaralar, kuchli fikrlar, muammolarni bartaraf etish bo'yicha kurashlar va unutilmas "buni kim sozlagan?" lahzalari yotadi.
Tarmoq shunchaki paketlarni bir nuqtadan ikkinchisiga o'tkazish emas, balki mantiq, strategiya va boshqariladigan betartiblikning aralashmasidir.
Turli protokollar turli yo'llarni bosib o'tishi mumkin, ammo yakuniy maqsad har doim bir xil: trafik oqimini saqlab qolish.
Va dizayn muhokamalari va real dunyodagi uzilishlar o'rtasida har bir muhandis ishlab chiqarishda eng katta qiyinchilik har doim ham tarmoq emas, balki uni loyihalashtiruvchi odamlar ekanligini bilib oladi.
Agar siz Routing protokoli bo'yicha mutaxassis bo'lishni istasangiz, biz bilan bog'laning

GRE tunnel va IPsec
IPsec nima qila olmaydi? Faqat unicast IP trafikni shifrlaydi. Multicast trafikni o'tkazmaydi, shunchaki tashlab yuboradi.
Bu nega muammo? Barcha dinamik routing protokollari (OSPF, EIGRP va boshqalar) bir-birini topish uchun multicast orqali "hello" yuboradi. Agar multicast o'tmasa — routing ishlamaydi.
GRE nima qiladi? Multicast trafikni oddiy unicast IP paket ichiga "o'raydi" (encapsulation). IPsec esa unicastni ko'rib, uni xursandchilik bilan shifrlaydi.
GRE — IPsec ko'ra olmaydigan narsani ko'radi.
IPsec — GRE himoya qila olmaydigan narsani himoya qiladi.
GRE aslida IPsec tufayli yaratilmagan" — GRE ancha oldinroq, boshqa maqsadlar uchun ixtiro qilingan. IPsec bilan birgalikda ishlatilishi keyinchalik kelgan.

Firewall Policy Process
Analyze Packet:
Firewall kirayotgan paketni tekshiradi:
source (qayerdan keldi)
destination (qayerga ketmoqda)
service/protocol (HTTP, HTTPS va hokazo)
Locate Policy
Paket atributlariga mos security policy qidiriladi.
Evaluate Rules
Rule’lar yuqoridan pastga tekshiriladi va birinchi mos kelgan rule tanlanadi.
Apply Action
Mos rule topilgach action bajariladi:
accept (ruxsat berish)
deny (bloklash)
Process Traffic
Yakunda trafik o‘tkaziladi yoki to‘xtatiladi.

Marshrutlash protokoli holatlarini o'zlashtirish: BGP va OSPF va IS-IS🚀
Marshrutlash protokollarini tushunish muhim, ammo ularning holatlarini bilish sizni tarmoqda chinakam boshqalardan ajratib turadi.
🛠 Muammolarni bartaraf etish bo'yicha maslahatlar:
BGP stuck in Active?->TCP (179-port), ulanish imkoniyati, ACLlarni tekshiring
OSPF stuck in 2-Way?->Eshittirish tarmoqlarida normalmi, DR/BDR ni tekshiring
IS-IS adjacency issues?->IIH paketlarini va daraja mos kelmasligini tekshiring

OSPF internet-provayder tarmoqlarini qanday boshqaradi (Oddiy vizual qo'llanma)
Bugungi internet-provayder muhitida marshrutizatsiya shunchaki ulanish haqida emas, balki tezlik, masshtablash va barqarorlik haqida. Aynan shu yerda OSPF (Eng qisqa yo'lni birinchi bo'lib ochish) muhim rol o'ynaydi.

Cyber Kill Chain — bu kiberhujum qanday bosqichma-bosqich amalga oshirilishini tushuntiradigan model.
U hujumni 7 ta asosiy bosqichga bo‘ladi:
1. Reconnaissance (Razvedka)
Hujumchi ma’lumot to‘playdi
— kompaniya, xodimlar, tizimlar haqida
👉 Masalan: ijtimoiy tarmoqlarni o‘rganish
2. Weaponization (Qurollantirish)
Topilgan ma’lumot asosida zararli vosita tayyorlanadi
👉 Masalan: virusli fayl yoki exploit yaratish
3. Delivery (Yetkazish)
Zararli fayl yoki link yuboriladi
👉 Ko‘pincha email orqali (phishing)
4. Exploitation (Foydalanish)
Tizimdagi zaiflikdan foydalaniladi
👉 Foydalanuvchi linkni bosadi yoki faylni ochadi
5. Installation (O‘rnatish)
Zararli dastur qurilmaga o‘rnatiladi
👉 Masalan: malware
6. Command and Control (C2)
Hujumchi qurilma ustidan masofadan nazorat o‘rnatadi
👉 Tashqi server bilan aloqa qiladi
7. Actions on Objectives (Maqsadga erishish)
Asosiy zarar shu yerda qilinadi:
ma’lumot o‘g‘irlash
tizimni buzish
pul talab qilish (masalan, ransomware)
