Learning Notes
Network Defense Essentials
Focused on core network security practices to identify threats early and strengthen defensive architecture.
Network hardeningThreat detectionIncident containment
What I Learned
- Understand common network attack paths and how attackers pivot across systems.
- Apply layered defense across segmentation, access policy, and endpoint controls.
- Use traffic and log indicators to triage suspicious behavior earlier.
How I Applied This
- Structured firewall and segmentation rules to reduce lateral movement risk.
- Improved alert triage by classifying events as reconnaissance, exploit, or post-exploit.
- Mapped incident response steps from detection to containment and recovery.
