feat: WAF auto-ban, cache busting, deployment docs, CVE Layer 7 docs

Changes:
- Enable WAF auto-ban by default (sensitivity: moderate, min_severity: high)
- Add whitelist for common safe IPs (localhost, router)
- Add browser cache busting via version parameter in CSS loads
- Document deployment scripts in secubox-tools/README.md
- Create CVE Layer 7 architecture documentation

WAF auto-ban now active with:
- 3 threats within 5 minutes triggers ban
- 4-hour ban duration
- Critical CVEs (Log4Shell, SQLi, CMDi) ban immediately

# SecuBox CVE Layer 7 Defense System
**Version:** 1.0.0
**Last Updated:** 2026-02-28
## Overview
The CVE Layer 7 innovation combines three defense pillars for comprehensive web application security:
1. **mitmproxy WAF** - Real-time threat pattern detection (70+ CVE patterns)
2. **CrowdSec Scenarios** - Intelligent ban decisions with adaptive thresholds
3. **CVE Triage Agent** - AI-powered vulnerability assessment and remediation
## Architecture

## Component 3: CVE Triage Agent
### Location
- **Config:** `/etc/config/cve-triage`
- **CLI:** `/usr/bin/cve-triage`
- **Library:** `/usr/lib/cve-triage/`
### Workflow
1. **Collector** (`collector.sh`):
- Gathers installed packages (opkg, dpkg, apk)
- Scans LXC containers and Docker images
- Cross-references with NVD API
2. **Analyzer** (`analyzer.sh`):
- CVSS-based severity scoring
- LocalAI impact assessment (optional)
- Attack vector analysis
3. **Recommender** (`recommender.sh`):
- Patch recommendations
- Mitigation strategies
- Monitoring guidance
4. **Applier** (`applier.sh`):
- Queue-based approval workflow
- Auto-apply option (configurable)
- Rollback capability
### Configuration
```uci
config cve-triage 'main'
option enabled '1'
option scan_interval '3600'
option min_severity 'medium'
option auto_apply_patches '0'
option localai_analysis '1'
```
## Integration Points
### mitmproxy → CrowdSec
1. mitmproxy writes JSON threat logs to `/data/threats.log`
2. CrowdSec `secubox-mitmproxy` parser extracts fields
3. 8 scenarios evaluate severity and decide ban duration
4. Firewall bouncer applies IP blocks
### mitmproxy → CVE Triage
1. CVE field from detection passed to triage agent
2. Triage correlates with NVD API
3. Generates remediation recommendations
4. Updates auto-ban sensitivity if needed
### Auto-Ban Feedback Loop
1. High-severity CVE attempts trigger immediate bans
2. Repeated attempts from same IP escalate ban duration
3. Whitelist/WireGuard endpoint protection prevents false positives
4. CrowdSec community blocklist integration

## Metrics & Monitoring
### Subdomain Metrics
Real-time JSON export: `/tmp/secubox-subdomain-metrics.json`
- Request counts per domain
- Threat type distribution
- Top 20 URIs per subdomain
- Country-based statistics
### Rate Limiting
```python
RATE_LIMITS = {
'path_scan': {'window': 60, 'max': 20},
'auth_attempt': {'window': 60, 'max': 10},
'bot_request': {'window': 60, 'max': 30},
'normal': {'window': 60, 'max': 100},
}
```
## Commands
### View active threats
```bash
# Recent threats
tail -f /data/threats.log | jq
# Auto-ban log
cat /data/autoban-requests.log
# CrowdSec decisions
cscli decisions list
```
### Manual ban/unban
```bash
# Ban IP for 4 hours
cscli decisions add --ip 1.2.3.4 --duration 4h --reason "Manual ban"
# Remove ban
cscli decisions delete --ip 1.2.3.4
```
### Check status
```bash
# mitmproxy WAF status
mitmproxyctl status
# CrowdSec status
cscli metrics
# CVE Triage status
cve-triage status
```
