πŸ—£ IPSEC IKE

⏺ IPSec xavfsiz tarmoq protokollari to'plami bo'lib, asosan xavfsiz bo'lmagan tarmoqlar orqali virtual xususiy tarmoq (VPN) ulanishlarini o'rnatish uchun ishlatiladi. IPSec xavfsiz ulanishlarni ta'minlash uchun Internet Key Exchange (IKE) protokolidan foydalanadi va tarmoq orqali yuborilgan ma'lumotlar paketlarini autentifikatsiya qiladi va shifrlaydi.

⏺ IPSEC IKE Flood - bu DDoS hujumining bir turi bo'lib, hujum qiluvchi ko'pincha soxta chiquvchi IP-manzillar bilan katta miqdordagi trafikni yuboradi va bu VPN serverining IKE trafigiga javob berishiga sabab bo'ladi. Natijada, VPN server resurslarining haddan tashqari iste'moli qayd etiladi, bu esa uning qonuniy mijozlarga (foydalanuvchilarga) kirishni rad etadi.

πŸ—£ Web Application Firewall

WAF yoki Web Application Firewall web-ilova va Internet o'rtasidagi HTTP trafigini filtrlash va nazorat qilish orqali web-ilovalarni himoya qilishga yordam beradi. U odatda web-ilovalarni Cross-Site Scripting (XSS), SQL injection va boshqalar kabi hujumlardan himoya qiladi.

WAF - bu 7-qavat xavfsizligi (OSI modelida) va barcha turdagi hujumlardan himoyalanish uchun mo'ljallanmagan. Ushbu hujumga qarshi mudofaa usuli odatda bir qator hujum vektorlariga qarshi yaxlit mudofaa yaratadigan vositalar to'plamining bir qismidir.

WAF - teskari proksi-serverning bir turi bo'lib, u mijozlar serverga yetib borishdan oldin WAF orqali o'tayotganda serverni ta'sir qilishdan himoya qiladi.

DDoS hujumi paytida WAF oxirgi himoya qatlami bo'lib, bloklangan manzillarni trafikni filtrlash markaziga uzatadi. Bu sizga provayder tarmog'iga yaqinlashganda, boshqa tarmoq qurilmalarining resurslarini bo'shatib, zararli trafikni darhol to'xtatishga imkon beradi.

DDoS hujumlaridan himoya qilish uchun faqat WAF-dan foydalanish tavsiya etilmaydi , chunki u keng ko'lamli hujumda muvaffaqiyatsizlikka uchragan birinchi elementlardan biridir. Web-ilovani DDoS hujumlaridan himoya qilish uchun maxsus service lardan (Cloudflare va boshqalar) dan foydalanish ancha samaralidir.

DNS orqali DDoS hujum (DNS Amplification Attack)

Hacker sizning qaysidir qurilmangizni (Asosan router yoki Server) ni ishdan chiqarmoqchi bo'lsa u sizga juda ko'plab paket jo'natishi kerak va (Qurilma, Website, Server) uni ko'rib chiqolmay o'z ishini bajarmay qo'yishi kerak. demak maqsad shu.
Buning uchun u virus tarqatib zombi kompyuterlardan foydalanadi yoki kattaroq DNS serverda bir qator narsani o'zgartirsa kifoya. qanday deysizmi?
tasaavvur qiling...
Butun dunyo www.google.com dan foydalanadi va sekundiga milliardlab so'rovlar kelib tushadi Google ga.
Agar hacker google domaini ostiga sizning (Qurilma, Website, Server) ipsini biriktirib qo'ysa bormi...
sekundiga millionlab paketlar sizni qurilmangizga keladi. Juda katta ehtimollik bilan uncha so'rovga sizning (Qurilma, Website, Server) javob berolmaydi va xizmat ko'rsatishni rad etadi (DDoS) va shu bilan hacker o'zi hohlaganiga erishishi mumkin.


Bunday hujumlardan qanday himoyalanish mumkin?

Trafikni filtrlash: Tarmoq qurilmalarida trafikni filtrlashni sozlash, DNS serverlarga faqat ruxsat berilgan manbalardan tashqari kirishni cheklash.
DNS ni sozlash: O'z serveringizni hujum uchun ishlatishni oldini olish uchun, refleksiv so'rovlarni cheklash.
Trafikni monitoring qilish: Oddiy ravishda DNS serverlarga ko'p so'rovlarni qilish mumkinligini aniqlash uchun trafikni doimiy ravishda kuzatish.
CDN va DDoS himoyasi xizmatlaridan foydalanish: Hujumni aniqlash va bartaraf etishga yordam berishi mumkin bo'lgan CDN va DDoS himoyasi xizmatlaridan foydalanish.
