This credential improved my network defense mindset, from traffic visibility to layered hardening and incident containment.

## Focus areas

- Network hardening
- Threat detection
- Incident 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.

## Applied in projects

- 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.
