Prebuilt build path
Follow these phases in order. Each one ends with a portfolio artifact you can show in GitHub, on your resume, or in interviews.
Step 1
Weeks 1-2
Build a segmented lab network
Show design discipline, not just device configuration.
- Design a small network with VLANs, routing, DHCP, DNS, and firewall rules.
- Document the topology and addressing plan like a change request.
Deliverable: A working lab with professional network documentation.
Step 2
Weeks 3-6
Troubleshoot and automate
Prove methodical debugging and modern network tooling.
- Capture and analyze traffic to debug three injected failure scenarios.
- Automate config backups or compliance checks with scripts.
Deliverable: Troubleshooting case studies plus automation scripts.
Step 3
Weeks 7-8
Package the proof for hiring
Turn the work into evidence recruiters and interviewers can verify quickly.
- Polish each repo README with screenshots, setup steps, architecture notes, and tradeoffs.
- Write resume bullets and interview talking points that map each project to Network Security Engineer job requirements.
Deliverable: Public GitHub proof, an updated resume, and interview-ready project stories.
