Network Security Foundation Master Class: learn core networking types, media and devices every blue-team analyst must know. We break down PAN-LAN-WAN, analog vs digital transmission, wired vs wireless links, plus hub-switch-router-firewall roles. Finish with real-world media-selection metrics (bandwidth, latency, jitter) so you can spot risks and harden any network. WHAT YOU’LL LEARN Scope-based network types: PAN, LAN, WLAN, CAN, MAN, WAN, GAN and SAN Analog vs digital transmission—why noise and modulation matter for security Wired vs wireless media: coax, twisted pair, fiber, radio, microwave, infrared Key devices and their weak spots: hub, switch, router, modem, firewall Performance metrics that expose risk: bandwidth, throughput, latency, jitter, BDP How Zero-Trust principles map onto modern multi-site SD-WAN designs Network Security https://www.youtube.com/watch?v=Y3ozkAFuiHc&list=PL0hT6hgexlYzX6AWwcyDbAZQUKYJL2Mdt&pp=gAQB SOC Playlist https://www.youtube.com/watch?v=zCLlrFZU0M8&list=PL0hT6hgexlYxd24Jb8OE7vZoas-iTcHAc CISO talks https://www.youtube.com/playlist?list=PL0hT6hgexlYwPTD-wC3oFBe27VGEiizg1 NIST Series https://www.youtube.com/watch?v=VcC_KabV_Ho&list=PL0hT6hgexlYy0vBwMv0eteiyAxB48RQzy&pp=gAQBiAQB GRC Series https://www.youtube.com/watch?v=mq_vSLHm4r0&list=PL0hT6hgexlYztA41j1bceTfVagP9mtq28&pp=gAQB ISO 27001 Video https://www.youtube.com/watch?v=sQqJH2naU6I&t=1454s&pp=ygUeaXNvIDI3MDAxIGltcGxlbWVudGF0aW9uIHN0ZXBz ISO 27001 Implementation Guide https://www.youtube.com/watch?v=GBfwk10Hh-o&pp=ygUeaXNvIDI3MDAxIGltcGxlbWVudGF0aW9uIHN0ZXBz GRC Practical Series https://www.youtube.com/playlist?list=PL0hT6hgexlYztA41j1bceTfVagP9mtq28 GRC Interview https://www.youtube.com/playlist?list=PL0hT6hgexlYz1Usn1Nrnur6OzVoz59zyl Internal Audit https://www.youtube.com/playlist?list=PL0hT6hgexlYyNWBcGYfabwumCr0GKmLWv Study with Me Telegram Group https://t.me/Infoseclearning My Instagram https://www.instagram.com/prabhnair/ My Spotify https://open.spotify.com/show/16M7QBKdPDW7CCzBgrrZRE #networksecurity #computernetworking #infosec #socanalyst #computernetworking #itnetworking
