Day 25: TCP/IP models explain in cybersecurity

📘 Day 25: TCP/IP Model in Cybersecurity (Mapped to OSI + WhatsApp Case Study) In this lesson, I break down the TCP/IP model and clearly map its 4 layers to the 7 OSI layers, showing how real-world cybersecurity works beyond theory. 🔹 I explain the 4 TCP/IP layers (Network Access, Internet, Transport, Application) 🔹 I map each TCP/IP layer to the corresponding OSI layers 🔹 I use WhatsApp as a real-life case study 🔹 I show threats at each layer (eavesdropping, spoofing, MITM, session hijacking, DDoS) 🔹 I explain the defensive controls WhatsApp security engineers use such as encryption, authentication, certificate validation, and traffic protection 🧠 Why this matters: Security teams don’t defend “the internet” they defend layers. Understanding TCP/IP + OSI helps you know where attacks happen and how they’re stopped. 🔐 Key takeaway: If you can map threats to layers, you can design strong defenses like a real security engineer. Ideal for cybersecurity beginners, SOC analysts, cloud security learners, and DevSecOps engineers. 🔗 Connect & Learn More • 🎥 YouTube:    / @sirlakewest   • 🎵 TikTok:   / sir_lakewest   • 💼 LinkedIn:   / olalekan-musa   #CyberSecurity #TCPIP #OSImodel #NetworkSecurity #InfoSec #CloudSecurity #BlueTeam #DevSecOps #EthicalHacking #LearnCyber #TechNigeria
