Remediation Priority
Remediation priority literacy — risk score, exposure, asset criticality, effort — rank `$CLOUD_LAB` finding backlog.
Visual · t31_remediation_priority
Remediation priority = named ranking rows. $CLOUD_LAB. Original Cyberlium.
Opening
Not every finding gets fixed today — name priority factors on YOUR lab backlog before drowning the team in low-severity noise.
Remediation priority literacy names: severity score, internet exposure category, asset criticality stub, exploitability category (without PoC — literacy from CVE/public exposure), fix effort estimate, and compensating control category. Analyst ranks five `$CLOUD_LAB` findings from Modules 6–8 — documents priority order with one-line rationale each — without reprioritizing to skip public exposure, without claiming 'accept all critical' without note, without unauthorized prod emergency change. Cyberlium teaches defender triage vocabulary — ordered backlog for mentor review. Refused: hiding critical findings at bottom, prod change without RoE, priority fraud. Lab row: prioritized finding list five items with rationale column.
1. Priority factors
Severity, exposure, criticality, exploitability literacy, effort — five ranking anchors.
Public exposure + critical severity typically outranks internal low — document rule.

Command — copy this
export CLOUD_LAB=${CLOUD_LAB:-$HOME/cyberlium-lab/t31-cloud}
python3 - <<'PY'
priority = ['Critical: public data + internet exposure', 'High: overprivileged IAM admin role', 'Medium: missing MFA on single user', 'Low: unused legacy resource cleanup']

cat > "$CLOUD_LAB/findings/remediation-priority.md" <<'EOF' # Remediation Priority — YOUR account findings 1. Exposed data (public S3, open SG on 22/3389) 2. Identity (admin roles, no MFA, stale keys) 3. Logging gaps (CloudTrail off, no Sentinel connector) 4. Container/K8s (privileged pods, missing NetworkPolicy) 5. Hygiene (unused resources, unpatched base images) Fix in YOUR account — never exploit stranger misconfigs EOF

Primary tools to practice this lesson: grep, python3. Reference sites: CVSS (https://www.first.org/cvss/); AWS priority (https://docs.aws.amazon.com/securityhub/latest/userguide/securityhub-findings-format.html); Azure secure score (https://learn.microsoft.com/en-us/azure/defender-for-cloud/secure-score-security-controls). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Backlog discipline
Each row links Module 8–6 finding ID — traceable to evidence pack.
Compensating control requires owner stub and review date UTC.
3. Refused
No priority fraud; no skip public bucket without documented accept.
Priority literacy supports fix order — not finding suppression.
4. What you ship: prioritized finding backlog
Five findings ranked + rationale each + NEVER hide critical line.
5. What you record before the next lesson
Prioritized finding backlog path.
6. Wrong vs right: stranger tenants vs YOUR cloud accounts
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Rank public S3 exposure finding last because 'lab only so ignore.'
Right
Prioritized backlog from `$CLOUD_LAB` findings. Next: Responsible Cloud.
Mission: prioritized finding backlog
1) Name five priority factors. 2) Rank five lab findings. 3) Rationale column per row. 4) Write NEVER hide critical line.
