Vulnerability › Module 1 › Lesson 4
RoE Lab
Pack VA RoE + asset note — literacy file only, dest $LAB_HOST.
Visual · va_roe_lab
Lab: write VA RoE pack. $LAB_HOST only. Original Cyberlium.
Opening
If the host is not $LAB_HOST in the pack, scanners do not get it.
Lessons 1–3 defined VA, wrote RoE, and locked the lab asset. This lab ships the artifact later modules reuse: a VA RoE file naming $LAB_HOST, allowed actions (inventory, credentialed scan per brief on lab only), and NEVER lines for stranger LANs, café Wi-Fi, internet ranges, and exploit PoCs on strangers. No production scan required — this is paperwork discipline VA analysts expect before any scanner job runs. Next: Quiz — VA Mindset and RoE.
1. Lab contract: write the pack first
Create $HOME/cyberlium-lab/t18-m01-l04-roe-lab.txt with date, operator, $LAB_HOST, allowed actions, and NEVER list.
Optional: one-line proof you can ping or SSH to $LAB_HOST — still no scanner run required in this lab.

═══ INSTALL ═══
Linux (Debian/Ubuntu):
Command — copy this
sudo apt install nmap
macOS:
Command — copy this
brew install nmap
Windows:
Command — copy this
choco install nmap # or download https://nmap.org/download.html
═══ LINUX / macOS ═══
Command — copy this
cat > "$HOME/cyberlium-lab/t18-roe.txt" <<'EOF' assets: 127.0.0.1 (lab VM only) methods: nmap -sn, -sV on named host stop: DoS, exploit PoCs on production EOF
Command — copy this
grep assets "$HOME/cyberlium-lab/t18-roe.txt" source "$HOME/cyberlium-lab/t18-lab.env"; nmap -sn "$LAB_HOST"
Primary tools to practice this lesson: grep, nmap. Reference sites: FIRST CVSS (https://www.first.org/cvss/); Greenbone OpenVAS (https://www.greenbone.net/en/openvas/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Cross-check against misuse patterns
Grep your notes for stranger IP examples and redact them to $LAB_HOST. If a tutorial screenshot shows a public cloud range, rewrite mentally to $LAB_HOST before you copy habits.
Classmates run their own lab VMs; do not 'share targets' by scanning each other's home PCs.
3. Lock the proof
chmod 600 on the pack. Quiz is next — then VA vs Pentest.
VA teams archive RoE with scan evidence; you are practicing that archive habit early.
4. What you ship: VA RoE pack for $LAB_HOST
RoE pack names $LAB_HOST. NEVER lines present. chmod 600. No stranger scans.
5. What you record before the next lesson
Date. RoE pack path. $LAB_HOST reachability note. File t18-m01-l04-roe-lab.txt chmod 600.
6. Wrong vs right: stranger nets vs YOUR lab assets
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Add a classmate's IP 'as a second target.' Skip the file and nmap anyway.
Right
Write YOUR pack for $LAB_HOST. chmod 600. Next: Quiz — VA Mindset and RoE.
Mission: freeze YOUR VA RoE on disk
1) Write RoE pack with who/what/where/stop. 2) Name $LAB_HOST. 3) Optional reachability note to $LAB_HOST only. 4) chmod 600. Never list stranger IPs.

RoE is boring on purpose — boring saves careers and keeps strangers' networks alone.
