qilish mexanizmlarini sinflarga ajratadi, shuning uchun Cisco ASA 5510
kompaniyaga kerak bo'lganda funksiyalarni kengaytirishga imkon beradi.
Cisco ASA 5525-X - Cisco SecureX freymidan foydalangan holda, ushbu model
xavfsizligi yanada murakkab tarmoqqa ega bo'lgan o'rta kompaniyalar uchun juda
mos keladi. SecureX texnologiyasi Cisco taqdim etadigan xavfsizlik yechimlarining
eng so'nggi versiyasidir.
Ishni bajarish tartibi
1.
Cisco packet tracer dasturi ishga tushiriladi.
2.
AMALIY ISH uchun cisco 2960 kommutatori, 2911 marshruzatori, ASA0
5505 firewalli, server va kompyuterlar tanlanadi.
3.
Quyida keltirilgan topologiya quriladi.
4.
Qurilgan topologiya testlab ko`riladi.
2-rasm. Tadqiq qilinayotgan tarmoq topologiyasi.
Qurilgan topologiyada quyidagi buyruqlar teriladi:
ASA0 ga quyidagi buyruqlar ketma ketligi kiritiladi.
