description	Guide for running a manual Docker security scan for the tracker runtime image and documenting results. Covers build, Trivy scan, CVE triage, per-CVE catalog updates, and scan history updates. Use when asked to run a manual container scan, triage Docker CVEs, or refresh security scan docs.

Run Manual Docker Security Scan

Use this workflow to run and document manual security scans for the tracker production container.

Scope

• Target image: tracker runtime image built from root Containerfile.
• Main severity gate: HIGH,CRITICAL.
• Documentation outputs:
  • docs/security/docker/scans/torrust-tracker.md
  • docs/security/docker/scans/README.md
  • docs/security/analysis/non-affecting/CVE-*.md (when non-affecting CVEs are analyzed)

Quick Commands

# 1) Build runtime image
docker build -t torrust-tracker:local -f Containerfile .

# 2) Gate scan (primary)
trivy image --severity HIGH,CRITICAL torrust-tracker:local

# 3) Full context scan (optional but recommended)
trivy image --severity MEDIUM,HIGH,CRITICAL torrust-tracker:local

Workflow

Step 1: Check Existing Catalog First

Before analyzing any CVE, search the existing catalog:

grep -R "CVE-<id>" docs/security/analysis/non-affecting/

If already present and requires-recheck-when conditions have not changed, reuse the existing verdict.

Step 2: Build and Scan

• Build local runtime image from Containerfile.
• Run the gate scan with HIGH,CRITICAL.
• Run optional full scan (MEDIUM,HIGH,CRITICAL) to capture trend context.

Step 3: Update Scan History Docs

Update:

• docs/security/docker/scans/torrust-tracker.md with:
  • date/time, Trivy version, totals by severity
  • notable CVEs and rationale
• docs/security/docker/scans/README.md summary table with latest status and date.

Step 4: Document New Non-Affecting CVEs

For any new non-affecting CVE, create docs/security/analysis/non-affecting/CVE-<id>.md with:

• frontmatter fields:
  • cve-id
  • date-analyzed
  • source
  • status: non-affecting
  • review-cadence
  • requires-recheck-when
• evidence-based explanation tied to tracker architecture
• conditions that would invalidate the current verdict

Step 5: Escalate Affecting CVEs

If a CVE is affecting:

• create/update a tracking issue
• include impact, affected component, exploitability context, and remediation plan
• update scan docs with current status and owner

Recheck Triggers

Re-evaluate catalog verdicts when any of these happen:

• Containerfile base image changes
• new runtime/system dependency is introduced
• code path changes that satisfy a CVE file's requires-recheck-when condition

Completion Checklist

• trivy gate scan executed (HIGH,CRITICAL)
• scan history files updated
• new CVEs cataloged or linked to existing catalog entries
• affecting CVEs escalated
• linter all passes
