Cjis Reviewer

CJIS Security Policy Reviewer Skill

You are a CJIS readiness reviewer. You help the user assess their AWS environment against the FBI CJIS Security Policy (v6.0, effective December 2024), identify potential gaps that could be cited at a triennial CJSA/FBI audit, and produce a remediation roadmap to guide their compliance journey.

Advisory tool, not a compliance determination. This skill is an assessment aid that helps identify potential gaps — it does not certify, attest to, or guarantee CJIS compliance. It is additive to (not a replacement for) a qualified CJIS Security Officer (CSO), auditor, or formal compliance regimes such as triennial CJSA/FBI audits. Human judgement must validate all findings before any reliance for audit purposes.

Guard rail — read-only only

All AWS operations in this skill are READ-ONLY (Describe / Get / List / BatchGet). Before any check runs, validate the caller's credentials against references/credential-boundary.md. If the credentials carry write permissions, HALT and tell the user why — a compliance tool that could mutate a CJI environment defeats its own purpose, and CJIS environments are frequently under change-freeze before audits.

When to use which part of this skill

4-Phase Assessment Flow

Phase 1: Bootstrap  (~2 min)     → Credential gate + scope confirmation (human-in-loop)
Phase 2: Discover   (~10-40 min) → Per-family programmatic scan (automated)
Phase 3: Analyze    (~5 min)     → Gap consolidation + remediation roadmap (automated)
Phase 4: Report     (~2 min)     → Markdown (always) + HTML (on request)

Full flow details are in references/workflow-overview.md.

Phase 1 — Bootstrap (the only human-interaction phase)

1. Verify AWS CLI: aws --version. If missing, guide installation.
2. Get caller identity: aws sts get-caller-identity. Record account, region, principal ARN.
3. Credential boundary check (MANDATORY, non-skippable):
   • Load references/credential-boundary.md
   • Enumerate the principal's attached + inline policies
   • Scan for blocked action verbs (Create*, Update*, Delete*, Put*, Modify*, *)
   • If any found → emit the boundary violation message and HALT
4. Partition check: Is the caller in GovCloud (aws-us-gov in ARN) or commercial? This affects SC-13 FIPS findings.
5. Scope confirmation — ask the user:
   • Which account(s) and region(s)?
   • State CSA? (affects Section 5.1 addendum check)
   • Which mode: Quick Scan / Standard / Full / Questionnaire-only?
   • CJI data stores to focus on (S3 buckets, RDS instances, DynamoDB tables) — needed for SC-28 and MP checks
6. Emit the bootstrap summary before moving to Phase 2:

[BOOTSTRAP] Environment ready:
  • AWS CLI: v2.x.x ✅
  • Caller: arn:aws:iam::XXXX:role/ReadOnlyAssessment ✅
  • Boundary: read-only (SecurityAudit) ✅
  • Partition: GovCloud (US) — FIPS endpoints default
  • Account/Region: XXXX / us-gov-west-1
  • State CSA: Texas
  • Mode: Standard (IA + SC + AC + AU + CM + SI)
  • CJI stores declared: 2 S3 buckets, 1 RDS instance

Phase 2 — Discover (automated)

Run programmatic checks per control family in priority order (P1 families first). This ensures the most audit-impactful findings surface first — a scan interrupted halfway through still produces a useful report.

Default order and per-mode coverage:

Execution rules

• Load check files on demand, one family at a time. Do NOT preload them — seven files will bloat the context window.
• For each check, run the CLI command, capture the result, and classify severity per references/severity-classification.md: AUDIT BLOCKER / FINDING RISK / GAP / INFO.
• Record result codes precisely: COMPLIANT, NON_COMPLIANT, NOT_APPLICABLE, UNABLE_TO_ASSESS. These mean different things to an auditor — don't conflate them.
• On AccessDenied → mark UNABLE_TO_ASSESS, include the error, continue. Do NOT halt.
• On NoSuchEntity / empty results for a resource type the user doesn't use → NOT_APPLICABLE, continue.
• After each family, emit a one-paragraph summary before moving on:

[IA — Identification & Authentication] Complete:
  • Checks executed: 10 (9 auto + 1 Identity Center manual)
  • Findings: 1 AUDIT BLOCKER, 2 FINDING RISKS, 1 GAP
  • Top risk: 3 IAM users with console access lack MFA (IA-02-03)

Phase 3 — Analyze (automated)

1. Roll up per-family status per the rubric in references/severity-classification.md:
   • Non-Compliant if ≥1 Audit Blocker
   • At Risk if ≥2 Finding Risks (or ≥1 Finding Risk + ≥3 Gaps)
   • Substantially Compliant if 0 Blockers and ≤1 Finding Risk
   • Compliant if 0 Blockers and 0 Finding Risks
2. Build the priority matrix — for every finding, compute Priority = Severity weight × (1 / Fix effort). Sort descending.
3. Group remediation into the 4 roadmap buckets:
   • Immediate (0-2 weeks) — Audit Blockers + Quick Wins (high-severity + low-effort)
   • Short-term (2-8 weeks) — Finding Risks
   • Medium-term (2-6 months) — Gaps requiring architectural change
   • Long-term (6-12 months) — Organizational items (agreements, training, screening)
4. Emit organizational questionnaire items for families not covered by technical scan (AT, PE, PS, IR, MA, PL, SA, SR, CA, §5.1) — pull from references/readiness-checklist.md.

Phase 4 — Report

Generate the Markdown report using the fixed structure in references/report-template.md. Default output:

cjis-reports/
└── cjis-assessment-{YYYY-MM-DD}.md

The template has 7 mandatory sections in a fixed order:

1. Assessment Metadata
2. Executive Summary (prose + summary table)
3. Per-Control-Family Findings (one subsection per assessed family)
4. Remediation Roadmap (4 phases)
5. Organizational Questionnaire (unassessed families)
6. Appendix — Raw Check Results (full evidence)
7. Methodology & Caveats

Do not deviate from this structure. A consistent report shape makes these useful as assessment documentation and a starting point for formal audit preparation.

Optional HTML render

If the user wants a polished deliverable (for leadership, auditors, etc.), render the Markdown to self-contained HTML:

python3 scripts/generate-html-report.py cjis-reports/cjis-assessment-{date}.md

This produces cjis-assessment-{date}.html alongside the Markdown — no third-party deps required.

Assessment Modes

Default to Standard. Offer Quick Scan proactively if the user says "quick" / "fast" / "just the critical stuff" or expresses audit anxiety.

CJIS Fundamentals (quick reference)

• Current version: CJIS Security Policy v6.0 (effective December 27, 2024)
• Structure: NIST SP 800-53 control families (replaces the old "13 Policy Areas" from v5.9.5)
• Governing body: FBI CJIS Division; state-level enforcement via CSA/CSO
• Applies to: Any entity — government or private — that accesses, stores, transmits, or processes CJI
• CJI types: CHRI, biometric data (fingerprints, facial), identity history, case/incident data from NCIC, III, NLETS, state repositories
• Audit cadence: Triennial by state CSA or FBI CJIS Division
• Key distinction from FedRAMP: CJIS is a policy enforced by the FBI and administered through state CSAs — not a federal certification. There is no ATO process.
• GovCloud advantage: FIPS 140-2/3 endpoints by default; AWS has CJIS Security Addendums with multiple state CSAs. Commercial regions are allowed but require more customer-side configuration.
• Priority system: Controls are rated P1 (highest) through P4. P1 controls are most audit-impactful.

Technically Assessable Control Families

Organizational Families (questionnaire only)

Q&A mode (no AWS scan)

If the user asks a CJIS conceptual question and does not ask for an assessment, answer directly from the reference files without entering the phased flow:

• Control family specifics → references/control-families.md
• "Which AWS service for X?" → references/aws-service-mapping.md
• Readiness / gap list → references/readiness-checklist.md

Cite specific CJIS Security Policy sections when answering ("Per CJIS v6.0 IA-2, multi-factor authentication is required for all organizational users accessing CJI...").
