Network Security Foundation MASTER Class 2025

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    • Network and Cybersecurity Interview Questi...   SOC Playlist    • Essential SOC Foundation Skills for Beginn...   CISO talks    • CISO Master Class   NIST Series    • NIST CSF - Identify Function ((Asset Manag...   GRC Series    • GRC Practical Approach - Part 1: Introduction   ISO 27001 Video    • Implementing ISO 27001 in an organization ...   ISO 27001 Implementation Guide    • ISO 27001 Like Never Seen Before: A Comple...   GRC Practical Series    • GRC Practical Series   GRC Interview    • GRC   Internal Audit    • Internal Audit   Study with Me Telegram Group https://t.me/Infoseclearning My Instagram   / prabhnair   My Spotify https://open.spotify.com/show/16M7QBK... #networksecurity #computernetworking #infosec #socanalyst #computernetworking #itnetworking
