# Phase 4: Security Design Review
**Type**: Evaluative
**Executor**: LLM
**Knowledge**: Control Sets, OWASP References
---
## ⚠️ MANDATORY: 4-Phase Gating Protocol (BLOCKING)
> **CRITICAL**: You MUST complete the following four stages in sequence and **output the result of each stage**. Skipping any stage will degrade analysis quality!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
### 🧠 THINKING - Phase 4 Entry Gate
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
**Purpose**: Understand deeply before acting. Prevent hasty actions based on incomplete understanding.
**⚠️ You MUST output THINKING results in the following format:**
```
🧠 THINKING - P4 Entry Gate
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📌 CORE PROBLEM
Evaluate project's design maturity across 16 security domains, identify security control gaps
📊 UPSTREAM DATA (Read from P1-P3 YAML)
| Metric | Value | Source |
|--------|-------|--------|
| P1 Total Modules | {actual_value} | P1_project_context.yaml → module_inventory.summary.total_modules |
| P2 Total Data Flows | {actual_value} | P2_dfd_elements.yaml → data_flow_traces.summary.total_flows |
| P2 Data Store Count | {actual_value} | P2_dfd_elements.yaml → data_store_inventory.summary.total_data_stores |
| P3 Boundary Count | {actual_value} | P3_boundary_context.yaml → boundary_context.boundaries length |
| Tech stack | {actual_value} | P1_project_context.yaml → project_context.tech_stack |
❓ UNKNOWNS
- Security controls to be confirmed through code review
- Best practices to be confirmed through KB queries
⚠️ RISKS
- Incomplete domain assessment (not all 16 domains covered)
- Missing traceability chain between Gap and Module/Flow
- Extended domain trigger detection missed
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⛔ STOP CHECK
- P1 YAML read? [YES/NO]
- P2 YAML read? [YES/NO]
- P3 YAML read? [YES/NO]
- Upstream data complete? [YES/NO]
- Ready to continue PLANNING? [YES/NO]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```
⛔ **STOP CONDITION**: If any STOP CHECK = NO → Read upstream data first before continuing
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
### 📋 PLANNING - Sub-task Decomposition
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
**Step 1: Read Upstream Data** (BLOCKING - MUST execute)
```bash
# Read P1-P3 YAML data (choose one method)
python scripts/phase_data.py --aggregate --phases 1,2,3 --format summary --root .
# Or read directly
cat .phase_working/{SESSION_ID}/data/P1_project_context.yaml
cat .phase_working/{SESSION_ID}/data/P2_dfd_elements.yaml
cat .phase_working/{SESSION_ID}/data/P3_boundary_context.yaml
```
⛔ If any file does not exist or is invalid → STOP and return to complete upstream Phase
**Step 2: Output Sub-task Table** (MANDATORY)
**⚠️ You MUST output PLANNING results in the following format:**
```
📋 PLANNING - P4 Sub-tasks
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
| # | Sub-task | Expected Output |
|---|----------|-----------------|
| T1 | Read P1-P3 data, extract module/flow/boundary inventory | Data structures |
| T2 | Assess 10 core security domains (AUTHN→DATA) | Domain assessment matrix |
| T3 | Detect extended domain trigger conditions (ext-11→ext-16) | Trigger detection results |
| T4 | Assess triggered extended domains | Extended domain assessment |
| T5 | Generate Gap inventory (GAP-xxx) | Gap inventory |
| T6 | Write P4_security_gaps.yaml | PRIMARY output |
| T7 | Write P4-SECURITY-REVIEW.md | SECONDARY output |
⛔ PLANNING CHECK
- Sub-tasks decomposed? [YES/NO]
- Ready to TaskCreate? [YES/NO]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```
**Step 3: TaskCreate for ALL sub-tasks** (MANDATORY)
⚠️ BEFORE starting any implementation, you MUST execute `TaskCreate` to create ALL sub-tasks!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
### ⚡ EXECUTION LOOP
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
For each sub-task:
1. `TaskUpdate(status: "in_progress")`
2. Execute sub-task
3. Verify: Does output meet expectations?
4. If verification passes: `TaskUpdate(status: "completed")` → proceed to next
5. If verification fails: Diagnose → Fix → Retry (max 3x) → If still failing: CHECKPOINT to request user decision
**Output Sequence** (CRITICAL):
1. **Write YAML FIRST**: `.phase_working/{SESSION_ID}/data/P4_security_gaps.yaml`
2. **Write MD SECOND**: `.phase_working/{SESSION_ID}/reports/P4-SECURITY-REVIEW.md`
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
### 🔍 REFLECTION - Completion Verification
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
**⚠️ After completing EXECUTION, you MUST output REFLECTION results in the following format:**
```
🔍 REFLECTION - P4 Completion Check
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
| Check Item | Status |
|------------|--------|
| All sub-tasks completed? (TaskList check) | [✅/❌] |
| P4_security_gaps.yaml exists and valid? | [✅/❌] |
| design_matrix contains all 16 domains? | [✅/❌] |
| Every Gap has unique ID (GAP-xxx)? | [✅/❌] |
| coverage_verification shows 100% coverage? | [✅/❌] |
| input_ref field points to P3_boundary_context.yaml? | [✅/❌] |
| Hook validation passed (exit 0)? | [✅/❌] |
⛔ COMPLETION GATE
- All checks passed? [YES/NO]
- Ready to proceed to P5? [YES/NO]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```
⛔ If ANY check fails → Fix and re-verify until ALL pass
---
## ⚠️ MANDATORY OUTPUT RULES
> **CRITICAL**: Phase 4 requires TWO outputs - a YAML data file AND a Markdown report.
### Dual Output Requirement
```
┌─────────────────────────────────────────────────────────────────────┐
│ PHASE 4 MUST PRODUCE TWO FILES: │
├─────────────────────────────────────────────────────────────────────┤
│ │
│ 1. DATA FILE (PRIMARY - Write First!) │
│ Path: .phase_working/{SESSION_ID}/data/P4_security_gaps.yaml │
│ Purpose: Structured gap data for P5/P6/P7 to read │
│ Format: Valid YAML with schema_version: "3.0.3 (20260209a)" │
│ │
│ 2. REPORT FILE (SECONDARY - Write After Data!) │
│ Path: .phase_working/{SESSION_ID}/reports/P4-SECURITY-REVIEW.md │
│ Purpose: Human-readable security design assessment │
│ Format: Markdown with assessment matrix and gap analysis │
│ │
│ ❌ FORBIDDEN: Writing only .md without .yaml │
│ ❌ FORBIDDEN: Embedding YAML blocks inside .md as data source │
│ ✅ REQUIRED: .yaml file is the authoritative data source │
│ │
└─────────────────────────────────────────────────────────────────────┘
```
### Required Data Sections in YAML
| Section | Validation |
|---------|------------|
| `security_gaps.gaps[]` | BLOCKING - all identified gaps with GAP-xxx IDs |
| `security_gaps.design_matrix` | BLOCKING - all 16 domains assessed |
| `security_gaps.summary` | BLOCKING - counts and statistics |
| `extended_domains_triggered[]` | CONDITIONAL - list triggered ext domains |
### Validation Gate
Phase 4 CANNOT complete until:
1. `.phase_working/{SESSION_ID}/data/P4_security_gaps.yaml` exists and is valid YAML
2. `design_matrix` contains all 16 domains (10 core + 6 extended)
3. Every gap has unique ID (GAP-xxx format) and risk_level assigned
4. Every domain has `assessed: true` or `assessed: false` (N/A)
5. `.phase_working/{SESSION_ID}/reports/P4-SECURITY-REVIEW.md` exists
### Coverage Verification (CRITICAL)
**P4 MUST verify complete coverage of P1/P2 inputs**:
```yaml
# In P4_security_gaps.yaml - REQUIRED section
coverage_verification:
# P1 Module Coverage
p1_modules:
total_modules: 15 # From P1.module_inventory.summary.total_modules
modules_assessed: 15 # Modules referenced in gaps or confirmed secure
coverage_percentage: 100 # MUST be 100%
unassessed_modules: [] # MUST be empty
# P2 Data Flow Coverage
p2_flows:
total_data_flows: 45 # From P2.dfd_elements.data_flows count
flows_assessed: 45 # Flows analyzed for security controls
coverage_percentage: 100 # MUST be 100%
unassessed_flows: [] # MUST be empty
# P2 Data Store Coverage
p2_stores:
total_data_stores: 8 # From P2.dfd_elements.data_stores count
stores_assessed: 8 # Stores with DATA domain assessment
coverage_percentage: 100 # MUST be 100%
unassessed_stores: [] # MUST be empty
```
**Validation Rules**:
- P1 Module Coverage: Every M-xxx from P1 must be referenced in at least one gap's `affected_elements` OR confirmed as secure
- P2 Flow Coverage: Every DF-xxx from P2 must be assessed for INPUT/OUTPUT/CRYPTO controls
- P2 Store Coverage: Every DS-xxx from P2 must be assessed for DATA domain compliance
**BLOCKING**: `coverage_percentage < 100%` for any category
---
### Domain Coverage Verification (GAP-5 FIX)
> **CRITICAL**: P4 MUST verify all 16 security domains are assessed with proper completeness criteria.

#### Domain Assessment Validation Rules
| Rule | Level | Description |
|------|-------|-------------|
| Core domain coverage | **BLOCKING** | All 10 core domains MUST be assessed |
| Extended trigger validation | **BLOCKING** | Triggered extended domains MUST be assessed |
| N/A justification | **WARNING** | Core domains marked N/A need documented reason |
| Check coverage | **WARNING** | `checks_passed / checks_performed < 0.5` triggers review |
| Gap-to-domain traceability | **BLOCKING** | Every GAP-xxx MUST reference exactly one domain |
#### Completeness Criteria Per Assessment Result
| Result | Criteria |
|--------|----------|
| **Yes** | All checklist items pass, no gaps identified |
| **Partial** | Some items pass, gaps identified but not critical |
| **No** | Critical controls missing, high-severity gaps |
| **N/A** | Domain not applicable (requires documented reason) |
**BLOCKING Conditions**:
- `core_domains.coverage_percentage < 100%`
- `extended_domains.assessment_coverage < 100%` (for triggered domains)
- Any gap without domain assignment
- Triggered extended domain with `assessed: false`
---
## Error Handling
| Error | Cause | Recovery Action |
|-------|-------|-----------------|
| P3 YAML not found | P3 not completed | Return to P3, complete boundary analysis |
| Domain assessment incomplete | Complex code | Document known state, mark domain as Partial |
| Extended domain trigger failure | Missing P1 data | Check P1 project_context, re-run detection |
| Gap count mismatch | YAML validation error | Verify gaps[] count matches summary.total_gaps |
**Fallback Strategy**: If domain assessment cannot be completed due to insufficient data, mark domain with `assessed: partial` and document the limitation.
---
## Input Context
← P1/P2/P3: All cumulative findings (from `{SESSION_ID}/data/` directory)
**Required Input Files**:
- `P1_project_context.yaml` - For tech stack detection (extended domain triggers)
- `P2_dfd_elements.yaml` - For security control mapping
- `P3_boundary_context.yaml` - For boundary-aware gap analysis
### ⚠️ MANDATORY: Query P1-P3 Data Before Analysis
**Before starting P4 analysis**, LLM MUST execute these queries to obtain upstream data:
```bash
# Step 1: Get aggregate summary from P1-P3
python scripts/phase_data.py --aggregate --phases 1,2,3 --format summary --root .
# Step 2: Get P1 modules for coverage tracking
python scripts/phase_data.py --query --phase 1 --type modules --root .
# Step 3: Get P2 DFD elements for security mapping
python scripts/phase_data.py --query --phase 2 --type dfd --root .
# Step 4: Get P3 boundaries for gap context
python scripts/phase_data.py --query --phase 3 --summary --root .
```
**Or read YAML directly**:
```bash
# PRIMARY sources - ALL REQUIRED
cat .phase_working/{SESSION_ID}/data/P1_project_context.yaml
cat .phase_working/{SESSION_ID}/data/P2_dfd_elements.yaml
cat .phase_working/{SESSION_ID}/data/P3_boundary_context.yaml
```
**CRITICAL**: Do NOT assess security domains from memory. MUST read P1-P3 data first!
**P3 Boundary Integration**:
- Use P3's `boundaries[]` to identify security control points
- Map gaps to `cross_boundary_flows[]` for risk context
- Reference `data_nodes[]` sensitivity when assessing DATA domain
- Consider Model/Agent boundary types for ext-13/ext-16 assessment
## Output Context
→ P5: `security_gaps` {gaps[], design_matrix{}}
---
## Core Analysis Goal
Evaluate project's design maturity across all 16 security domains, identify gaps between current implementation and security best practices.
---
## Knowledge Reference (Progressive Loading)
1. **Always load**: `security-design.yaml` (16 domains overview)
2. **Per domain**: `control-set-*.md` when assessing that domain
3. **For details**: `reference-set-*.md` for specific implementation guidance
**Query Commands**:
```bash
$SKILL_PATH/kb --control authentication # Domain-specific controls
$SKILL_PATH/kb --stride-controls S # STRIDE category controls
$SKILL_PATH/kb --control api --full # Full control details
$SKILL_PATH/kb --control {ext_domain} --full # Extended domain (may have limited support)
```
### KB Usage Log (MANDATORY per GAP-4 Contract)
> **CRITICAL**: P4 MUST query KB for each assessed security domain per KBQueryContract in assets/contracts/data-model.yaml
**Required Queries**:
1. `--control {domain_code}` - For each core domain (AUTHN, AUTHZ, INPUT, etc.)
2. `--stride-controls {S|T|R|I|D|E}` - For STRIDE-to-domain mapping validation
```yaml
# In P4_security_gaps.yaml - MANDATORY section (GAP-4 Contract)
kb_usage_log:
# Query record for auditability

action_taken: "Used LLM knowledge for ext-16 assessment"
domain_affected: AGENT
kb_available: true
note: "Extended domains (ext-11 to ext-16) may not have full KB support"
```
**Validation Rules** (GAP-4 Contract):
- **WARNING**: `kb_coverage_percentage < 50%` for core domains (01-10)
- **INFO**: Extended domains (ext-11 to ext-16) queries are optional
- **BLOCKING**: None - KB queries are best-effort but strongly recommended

## Assessment Process
For each domain:
1. **Identify Implementation**: What security controls exist in the code?
2. **Compare to Standards**: How does it compare to OWASP/industry standards?
3. **Assess Maturity**: Rate as Yes/No/Partial
4. **Document Gaps**: What's missing or inadequate?
5. **Assign Risk Level**: High/Medium/Low based on impact
---
## Assessment Matrix Template
| Domain | Code | Current Implementation | Assessment | Gap Description | Risk Level | KB Ref |
|--------|------|----------------------|------------|-----------------|------------|--------|
| Authentication | AUTHN | OAuth2 + local auth | Partial | MFA not implemented | High | control-set-01 |
| Authorization | AUTHZ | Role-based access | Yes | - | Low | control-set-02 |
| Input Validation | INPUT | Basic sanitization | Partial | Missing schema validation | Medium | control-set-03 |
| ... | ... | ... | ... | ... | ... | ... |
**Assessment Values**:
- **Yes**: Fully implemented per standards
- **Partial**: Partially implemented, gaps exist
- **No**: Not implemented
- **N/A**: Not applicable to this project
