|
||||
## 1. Overview
|
||||
|
||||
### What are Unknowns?
|
||||
|
||||
Unknowns are items that could not be fully classified during scanning due to:
|
||||
|
||||
- Missing VEX statements
|
||||
- Ambiguous indirect calls in call graphs
|
||||
- Incomplete SBOM data
|
||||
- Missing advisory information
|
||||
- Conflicting evidence from multiple sources
|
||||
|
||||
### Unknown Ranking
|
||||
|
||||
Unknowns are ranked using a 2-factor scoring model:
|
||||
|
||||
```
|
||||
score = 0.60 × blast + 0.30 × scarcity + 0.30 × pressure + containment_deduction
|
||||
```
|
||||
|
||||
| Factor | Weight | Description |
|
||||
|--------|--------|-------------|
|
||||
| Blast Radius | 0.60 | Impact scope (dependents, network exposure) |
|
||||
| Evidence Scarcity | 0.30 | How much data is missing |
|
||||
| Exploit Pressure | 0.30 | EPSS score, KEV status |
|
||||
| Containment | -0.20 | Mitigation factors (seccomp, read-only FS) |
|
||||
|
||||
### Band Assignment
|
||||
|
||||
| Band | Score Range | Priority | SLA |
|
||||
|------|-------------|----------|-----|
|
||||
| HOT | ≥ 0.70 | Critical | 24 hours |
|
||||
| WARM | 0.40 - 0.69 | Normal | 7 days |
|
||||
| COLD | < 0.40 | Low | 30 days |
|
||||

|
||||
|
||||
## 3. Triage Procedures
|
||||
|
||||
### 3.1 Daily Triage Workflow
|
||||
|
||||
**Schedule**: Daily at 9:00 AM
|
||||
|
||||
**Duration**: 30 minutes
|
||||
|
||||
**Participants**: Security analyst, on-call engineer
|
||||
|
||||
**Process**:
|
||||
|
||||
```bash
|
||||
# 1. Get today's queue snapshot
|
||||
stella unknowns snapshot --output daily-$(date +%Y%m%d).json
|
||||
|
||||
# 2. Review all HOT items
|
||||
stella unknowns list --band HOT --since 24h
|
||||
|
||||
# 3. For each HOT unknown, determine action:
|
||||
# - Escalate: Trigger immediate rescan
|
||||
# - Investigate: Needs manual analysis
|
||||
# - Defer: Move to WARM (with justification)
|
||||
# - Resolve: Evidence found, can close
|
||||
|
||||
# 4. Process each item
|
||||
stella unknowns triage unk-12345678-... --action escalate
|
||||
stella unknowns triage unk-87654321-... --action investigate --notes "Need VEX from vendor"
|
||||
stella unknowns triage unk-11111111-... --action defer --reason "False positive suspected"
|
||||
```
|
||||
|
||||
### 3.2 Triage Decision Matrix
|
||||
|
||||
| Reason Code | KEV | EPSS > 0.5 | Action |
|
||||
|-------------|-----|------------|--------|
|
||||
| `missing_vex` | Yes | Any | Escalate + Vendor outreach |
|
||||
| `missing_vex` | No | Yes | Escalate |
|
||||
| `missing_vex` | No | No | Request VEX |
|
||||
| `ambiguous_indirect_call` | Any | Any | Manual code review |
|
||||
| `incomplete_sbom` | Any | Any | Rescan with updated extractor |
|
||||
| `conflicting_evidence` | Any | Any | Manual analysis |
|
||||
|
||||
### 3.3 Triage Templates
|
||||
|
||||
```bash
|
||||
# Quick escalate (HOT + KEV)
|
||||
stella unknowns triage unk-... --action escalate \
|
||||
--priority P1 \
|
||||
--notes "KEV item, requires immediate attention"
|
||||
|
||||
# Request vendor VEX
|
||||
stella unknowns triage unk-... --action investigate \
|
||||
--notes "Requested VEX from vendor via security@vendor.com" \
|
||||
--due-date 7d
|
||||
|
||||
# Mark for code review
|
||||
stella unknowns triage unk-... --action investigate \
|
||||
--notes "Requires manual code review to resolve indirect call" \
|
||||
--assign @code-review-team
|
||||
|
||||
# Defer with justification
|
||||
stella unknowns triage unk-... --action defer \
|
||||
--reason "Component not deployed to production" \
|
||||
--evidence "deployment-manifest.yaml shows staging-only"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. Escalation Workflows
|
||||
|
||||
### 4.1 Automatic Escalation
|
||||
|
||||
Unknowns are automatically escalated when:
|
||||
|
||||
- Score increases above HOT threshold (0.70)
|
||||
- KEV status added to related CVE
|
||||
- EPSS score increases significantly (> 0.2 delta)
|
||||
- Blast radius increases (new dependents detected)
|
||||
|
||||
**Configure auto-escalation**:
|
||||
|
||||
```yaml
|
||||
# policy.unknowns.escalation.yaml
|
||||
autoEscalation:
|
||||
enabled: true
|
||||
triggers:
|
||||
- condition: score >= 0.70
|
||||
action: escalate
|
||||
notify: [security-team]
|
||||
- condition: kev == true
|
||||
action: escalate
|
||||
priority: P1
|
||||
notify: [security-team, management]
|
||||
- condition: epss_delta > 0.2
|
||||
action: escalate
|
||||
notify: [security-team]
|
||||
```
|
||||
|
||||
### 4.2 Manual Escalation
|
||||
|
||||
```bash
|
||||
# Escalate via CLI
|
||||
stella unknowns escalate unk-12345678-...
|
||||
|
||||
# Escalate with reason
|
||||
stella unknowns escalate unk-12345678-... \
|
||||
--reason "Customer reported potential exploit"
|
||||
|
||||
# Escalate to trigger rescan
|
||||
stella unknowns escalate unk-12345678-... --rescan
|
||||
|
||||
# Output:
|
||||
# Escalated: unk-12345678-...
|
||||
# Rescan job: rescan-job-001
|
||||
# Status: queued
|
||||
# ETA: 5 minutes
|
||||
```
|
||||
|
||||
### 4.3 Bulk Escalation
|
||||
|
||||
```bash
|
||||
# Escalate all KEV items
|
||||
stella unknowns escalate --filter "kev=true" --reason "KEV bulk escalation"
|
||||
|
||||
# Escalate high-score items
|
||||
stella unknowns escalate --filter "score>=0.8" --rescan
|
||||
|
||||
# Escalate by artifact
|
||||
stella unknowns escalate --artifact sha256:abc123... --reason "Production incident"
|
||||
```
|
||||
|
||||
### 4.4 Escalation SLA Tracking
|
||||
|
||||
```bash
|
||||
# Check SLA status
|
||||
stella unknowns sla-status
|
||||
|
||||
# Output:
|
||||
# HOT unknowns SLA (24h):
|
||||
# In SLA: 10 (83%)
|
||||
# Breached: 2 (17%)
|
||||
#
|
||||
# Breached items:
|
||||
# unk-111... (26h old) - missing_vex
|
||||
# unk-222... (30h old) - conflicting_evidence
|
||||
|
||||
# Get SLA breach notifications
|
||||
stella unknowns list --sla-breached
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 5. Resolution Procedures
|
||||
|
||||
### 5.1 Resolution Types
|
||||
|
||||
| Resolution | Description | Evidence Required |
|
||||
|------------|-------------|-------------------|
|
||||
| `not_affected` | Vulnerability doesn't apply | VEX statement or manual analysis |
|
||||
| `fixed` | Vulnerability patched | Version upgrade confirmation |
|
||||
| `mitigated` | Controls in place | Mitigation documentation |
|
||||
| `false_positive` | Incorrect classification | Analysis report |
|
||||
| `wont_fix` | Accepted risk | Risk acceptance form |
|
||||
|
||||
### 5.2 Resolve Unknown
|
||||
|
||||
```bash
|
||||
# Resolve as not affected
|
||||
stella unknowns resolve unk-12345678-... \
|
||||
--resolution not_affected \
|
||||
--justification "vulnerable_code_not_present" \
|
||||
--notes "Manual code review confirmed function not used"
|
||||
|
||||
# Resolve as fixed
|
||||
stella unknowns resolve unk-12345678-... \
|
||||
--resolution fixed \
|
||||
--justification "version_upgraded" \
|
||||
--evidence "Upgraded lodash to 4.17.21, CVE patched"
|
||||
|
||||
# Resolve as mitigated
|
||||
stella unknowns resolve unk-12345678-... \
|
||||
--resolution mitigated \
|
||||
--justification "inline_mitigations_exist" \
|
||||
--evidence "WAF rule WAF-001 blocks exploit pattern"
|
||||
|
||||
# Resolve as won't fix (risk accepted)
|
||||
stella unknowns resolve unk-12345678-... \
|
||||
--resolution wont_fix \
|
||||
--justification "risk_accepted" \
|
||||
--evidence "Risk acceptance ticket RISK-123" \
|
||||
--expires 90d # Re-evaluate in 90 days
|
||||
```
|
||||
|
||||
### 5.3 Bulk Resolution
|
||||
|
||||
```bash
|
||||
# Resolve all items for a fixed package version
|
||||
stella unknowns resolve-batch \
|
||||
--filter "purl=pkg:npm/lodash@4.17.20" \
|
||||
--resolution fixed \
|
||||
--justification "Upgraded to 4.17.21 fleet-wide" \
|
||||
--evidence "Fleet upgrade ticket FLEET-456"
|
||||
|
||||
# Resolve false positives from analysis
|
||||
stella unknowns resolve-batch \
|
||||
--file false-positives.json \
|
||||
--resolution false_positive
|
||||
```
|
||||
|
||||
### 5.4 Resolution Audit Trail
|
||||
|
||||
```bash
|
||||
# View resolution history
|
||||
stella unknowns history unk-12345678-...
|
||||
|
||||
# Output:
|
||||
# 2025-12-15 10:00:00 - Created (score: 0.62)
|
||||
# 2025-12-16 09:30:00 - Triaged by analyst@example.com
|
||||
# 2025-12-17 14:00:00 - Escalated (KEV added)
|
||||
# 2025-12-18 11:00:00 - Resolved by security@example.com
|
||||
# Resolution: not_affected
|
||||
# Justification: vulnerable_code_not_present
|
||||
# Notes: Manual code review confirmed function not used
|
||||
|
||||
# Export audit trail
|
||||
stella unknowns audit-export --from 2025-01-01 --to 2025-12-31 --output audit.json
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. Troubleshooting
|
||||
|
||||
### 6.1 Score Seems Wrong
|
||||
|
||||
**Symptom**: Unknown scored too high or too low.
|
||||
|
||||
**Diagnosis**:
|
||||
|
||||
```bash
|
||||
# View score breakdown
|
||||
stella unknowns show unk-... --score-details
|
||||
|
||||
# View proof tree
|
||||
stella unknowns proof unk-... --verbose
|
||||
```
|
||||
|
||||
**Common causes**:
|
||||
|
||||
1. **Stale EPSS data**: EPSS feed not updated
|
||||
2. **Incorrect blast radius**: Dependency data outdated
|
||||
3. **Missing containment data**: Seccomp/filesystem status unknown
|
||||
|
||||
**Resolution**:
|
||||
|
||||
```bash
|
||||
# Trigger score recalculation
|
||||
stella unknowns recalculate unk-...
|
||||
|
||||
# Force refresh of all input signals
|
||||
stella unknowns refresh unk-... --force
|
||||
```
|
||||
|
||||
### 6.2 Duplicate Unknowns
|
||||
|
||||
**Symptom**: Same issue appears multiple times.
|
||||
|
||||
**Diagnosis**:
|
||||
|
||||
```bash
|
||||
# Find potential duplicates
|
||||
stella unknowns duplicates --scan
|
||||
|
||||
# Output shows items with same CVE+PURL but different artifacts
|
||||
```
|
||||
|
||||
**Resolution**:
|
||||
|
||||
```bash
|
||||
# Merge duplicates
|
||||
stella unknowns merge \
|
||||
--primary unk-111... \
|
||||
--secondary unk-222... \
|
||||
--reason "Same CVE across artifact versions"
|
||||
```
|
||||
|
||||
### 6.3 Escalation Not Working
|
||||
|
||||
**Symptom**: Escalation doesn't trigger rescan.
|
||||
|
||||
**Diagnosis**:
|
||||
|
||||
```bash
|
||||
# Check escalation status
|
||||
stella unknowns escalation-status unk-...
|
||||
|
||||
# Check Scheduler connectivity
|
||||
stella health check --service scheduler
|
||||
|
||||
# Check job queue
|
||||
stella scheduler queue status rescan
|
||||
```
|
||||
|
||||
**Resolution**:
|
||||
|
||||
```bash
|
||||
# Retry escalation
|
||||
stella unknowns escalate unk-... --force
|
||||
|
||||
# Manual rescan trigger
|
||||
stella scan trigger --artifact sha256:abc123... --priority high
|
||||
```
|
||||
|
||||
### 6.4 Resolution Rejected
|
||||
|
||||
**Symptom**: Resolution attempt fails validation.
|
||||
|
||||
**Diagnosis**:
|
||||
|
||||
```bash
|
||||
# Check resolution requirements
|
||||
stella unknowns resolution-requirements unk-...
|
||||
|
||||
# Output:
|
||||
# Resolution requirements for unk-12345678-...
|
||||
# - Justification: required
|
||||
# - Evidence: required (reason: KEV item)
|
||||
# - Approver: required (band: HOT)
|
||||
```
|
||||
|
||||
**Resolution**:
|
||||
|
||||
```bash
|
||||
# Provide required evidence
|
||||
stella unknowns resolve unk-... \
|
||||
--resolution not_affected \
|
||||
--justification "vulnerable_code_not_present" \
|
||||
--evidence "Code review: CRV-123" \
|
||||
--approver security-lead@example.com
|
||||
```
