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 LEARNScope-based network types: PAN, LAN, WLAN, CAN, MAN, WAN, GAN and SANAnalog vs digital transmission—why noise and modulation matter for securityWired vs wireless media: coax, twisted pair, fiber, radio, microwave, infraredKey devices and their weak spots: hub, switch, router, modem, firewallPerformance metrics that expose risk: bandwidth, throughput, latency, jitter, BDPHow Zero-Trust principles map onto modern multi-site SD-WAN designsNetwork Security https://www.youtube.com/watch?v=Y3ozkAFuiHc&list=PL0hT6hgexlYzX6AWwcyDbAZQUKYJL2Mdt&pp=gAQBSOC Playlisthttps://www.youtube.com/watch?v=zCLlrFZU0M8&list=PL0hT6hgexlYxd24Jb8OE7vZoas-iTcHAcCISO talkshttps://www.youtube.com/playlist?list=PL0hT6hgexlYwPTD-wC3oFBe27VGEiizg1NIST Serieshttps://www.youtube.com/watch?v=VcC_KabV_Ho&list=PL0hT6hgexlYy0vBwMv0eteiyAxB48RQzy&pp=gAQBiAQBGRC Serieshttps://www.youtube.com/watch?v=mq_vSLHm4r0&list=PL0hT6hgexlYztA41j1bceTfVagP9mtq28&pp=gAQBISO 27001 Videohttps://www.youtube.com/watch?v=sQqJH2naU6I&t=1454s&pp=ygUeaXNvIDI3MDAxIGltcGxlbWVudGF0aW9uIHN0ZXBzISO 27001 Implementation Guidehttps://www.youtube.com/watch?v=GBfwk10Hh-o&pp=ygUeaXNvIDI3MDAxIGltcGxlbWVudGF0aW9uIHN0ZXBzGRC Practical Serieshttps://www.youtube.com/playlist?list=PL0hT6hgexlYztA41j1bceTfVagP9mtq28GRC Interviewhttps://www.youtube.com/playlist?list=PL0hT6hgexlYz1Usn1Nrnur6OzVoz59zylInternal Audithttps://www.youtube.com/playlist?list=PL0hT6hgexlYyNWBcGYfabwumCr0GKmLWvStudy with MeTelegram Grouphttps://t.me/InfoseclearningMy Instagramhttps://www.instagram.com/prabhnair/My Spotifyhttps://open.spotify.com/show/16M7QBKdPDW7CCzBgrrZRE#networksecurity #computernetworking #infosec #socanalyst #computernetworking #itnetworking
