RoE Lab
Pack secure-coding RoE + repo note — literacy file only, dest $MY_REPO.
Visual · secure_coding_roe_lab
Lab: write secure-coding RoE pack. $MY_REPO only. Original Cyberlium.
If the repo is not $MY_REPO in the pack, scanners do not get it.
Lessons 1–3 defined secure coding, wrote RoE, and locked the repo boundary. This lab ships the artifact later modules reuse: a secure-coding RoE file naming $MY_REPO, allowed actions (read code, add validation, run local tests per brief), and NEVER lines for stranger SaaS, live shops, and sqlmap on URLs you do not own. No production deploy required — this is paperwork discipline developers expect before any security tool runs. Next: Quiz — Secure Coding Mindset and RoE.
1. Lab contract: write the pack first
Create $HOME/cyberlium-lab/t17-m01-l04-roe-lab.txt with date, operator, $MY_REPO, allowed actions, and NEVER list.
Optional: one-line proof you can open $MY_REPO locally — still no scanner runs required in this lab.

Primary tools to practice this lesson: grep, openssl. Reference sites: OWASP RoE guidance (https://owasp.org/www-project-web-security-testing-guide/); NIST SSDF (https://csrc.nist.gov/publications/detail/sp/800-218/final). 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 URL examples and redact them to localhost or $MY_REPO. If a tutorial screenshot shows a live shop domain, rewrite mentally to your toy app before you copy habits.
Classmates run their own lab repos; do not 'share targets' by testing each other's production deploys.
3. Lock the proof
chmod 600 on the pack. Quiz is next — then Secure SDLC.
Secure teams archive RoE with review evidence; you are practicing that archive habit early.
4. What you ship: secure-coding RoE pack for $MY_REPO
RoE pack names $MY_REPO. NEVER lines present. chmod 600. No stranger SaaS.
5. What you record before the next lesson
Date. RoE pack path. $MY_REPO path note. File t17-m01-l04-roe-lab.txt chmod 600.
6. Wrong vs right: stranger apps vs YOUR repo
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Add a classmate's deploy URL 'as a second target.' Skip the file and run sqlmap anyway.
- Right: Write YOUR pack for $MY_REPO. chmod 600. Next: Quiz — Secure Coding Mindset and RoE.
Mission: freeze YOUR secure-coding RoE on disk
1) Write RoE pack with who/what/where/stop. 2) Name $MY_REPO. 3) Optional local repo path note. 4) chmod 600. Never list stranger URLs.
