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.

═══ INSTALL ═══

Linux (Debian/Ubuntu):

Command — copy this

sudo apt install python3

macOS:

Command — copy this

brew install python3

Windows: Download https://python.org/downloads/

═══ LINUX / macOS ═══

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']
print('Remediation priority (YOUR account):')
for p in priority: print(f'  - {p}')
PY

Command — copy this

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

Command — copy this

grep -E 'Priority|YOUR account|never exploit' "$CLOUD_LAB/findings/remediation-priority.md"

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.
