Remediation Lab
Patch one P1 on YOUR lab VM, update tracker, retest, document — no exploit PoCs.
Visual · t18_remediation_lab
Lab: remediate + retest on $LAB_ASSETS. Original Cyberlium.
Patch your lab VM, rescan it, close the row — that is defender closure, not neighbor router chaos.
On $LAB_ASSETS: (1) pick one P1 from remediation tracker; (2) apply patch or documented compensate on YOUR lab VM (snapshot first); (3) update tracker Owner/Due/Status; (4) retest with safe method; (5) mark Closed with evidence. Optional: accept one low finding with review date and justification. chmod 600 all notes. No patching systems you do not own, no exploit validation, no scanning new unauthorized hosts.
1. Patch or compensate
Snapshot VM before change. Record package versions before/after.
If compensate only — document rule and schedule patch follow-up.

2. Tracker update
Status progression Open → In Progress → Closed with dates.
Link retest evidence to report finding ID.
3. Teardown

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: Patch neighbor device 'to help them' without permission.
- Right: Remediation + retest on $LAB_ASSETS. Next: quiz.
