7-8-LABARATORIYA ISHI

Topshirdi : Xonimqulov Jahongir
Qabul qildi : Toshboyev Jahongir

Mavzu: Cisco Packet Tracer dasturida SNTP protokoli bilan ishlash

Ishdan maqsad: Cisco Packet Tracer dasturi yordamida SNTP protokoli bilan ishlashni o’rganish. Tarmoq qurilmalari vaqtini NTP-server yordamida sozlash.

8-labaratoriya

Mavzu: Cisco Packet Tracer dasturida port xavfsizligini ta’minlash

Ishdan maqsad: Kommutatsiya jadvallari to`ldirilishiga yo`naltirilgan hujumlardan, tarmoqni himoya qilish imkonini beruvchi kommutatorning “port- security” funksiyasini sozlash bo`yicha amaliy ko`nikmalarga ega bo’lish.
