Security is the foundation of every network. Without it, attackers steal data, disrupt services, and compromise your infrastructure.
I'll cover these core concepts:
- CIA triad and what it protects
- Common attack types and how attackers think
- Defense in depth and layered protection
- Network segmentation and security zones
- Risk assessment and security policies
- Incident response when things go wrong
You'll learn to think like both a defender and an attacker. This mindset helps you build networks resilient against real-world threats.
