## Capabilities

### 1. OWASP ZAP Baseline Scan

Quick passive scan for common vulnerabilities:

```bash
# Docker-based baseline scan
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-baseline.py \
  -t https://target.example.com \
  -J baseline-report.json

# With configuration file
docker run -v $(pwd):/zap/wrk:rw -t ghcr.io/zaproxy/zaproxy:stable zap-baseline.py \
  -t https://target.example.com \
  -c zap-baseline.conf \
  -J baseline-report.json

# Include AJAX spider for JavaScript-heavy apps
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-baseline.py \
  -t https://target.example.com \
  -j \
  -J baseline-report.json
```

### 2. OWASP ZAP Full Scan

Comprehensive active scanning:

```bash
# Full scan (includes active scanning)
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-full-scan.py \
  -t https://target.example.com \
  -J full-scan-report.json

# Full scan with longer timeout
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-full-scan.py \
  -t https://target.example.com \
  -m 60 \
  -J full-scan-report.json

# Scan with custom policy
docker run -v $(pwd):/zap/wrk:rw -t ghcr.io/zaproxy/zaproxy:stable zap-full-scan.py \
  -t https://target.example.com \
  -z "-config scanner.strength=INSANE" \
  -J full-scan-report.json
```

### 3. OWASP ZAP API Scan

For REST/GraphQL API testing:

```bash
# Scan with OpenAPI spec
docker run -v $(pwd):/zap/wrk:rw -t ghcr.io/zaproxy/zaproxy:stable zap-api-scan.py \
  -t openapi.yaml \
  -f openapi \
  -J api-scan-report.json

# Scan with GraphQL schema
docker run -v $(pwd):/zap/wrk:rw -t ghcr.io/zaproxy/zaproxy:stable zap-api-scan.py \
  -t https://api.example.com/graphql \
  -f graphql \
  -J graphql-scan-report.json

# API scan with auth header
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-api-scan.py \
  -t https://api.example.com/openapi.json \
  -f openapi \
  -z "-config replacer.full_list(0).description=auth \
      -config replacer.full_list(0).enabled=true \
      -config replacer.full_list(0).matchtype=REQ_HEADER \
      -config replacer.full_list(0).matchstr=Authorization \
      -config replacer.full_list(0).replacement='Bearer TOKEN'" \
  -J api-scan-report.json
```

### 4. Authenticated Scanning

```bash
# Form-based authentication
docker run -t ghcr.io/zaproxy/zaproxy:stable zap-full-scan.py \
  -t https://target.example.com \
  -z "-config authentication.method=formBasedAuthentication \
      -config authentication.loginUrl=https://target.example.com/login \
      -config authentication.username=testuser \
      -config authentication.password=testpass" \
  -J auth-scan-report.json

# Session token authentication
# Create context file first
docker run -v $(pwd):/zap/wrk:rw -t ghcr.io/zaproxy/zaproxy:stable zap-full-scan.py \
  -t https://target.example.com \
  -n context.context \
  -J auth-scan-report.json
```

### 5. OWASP Top 10 2021 Detection

#### A01:2021 - Broken Access Control

```bash
# ZAP rules for access control testing
# Active scan policy focusing on access control
zap-cli active-scan \
  --scanpolicyname "access-control" \
  --recurse \
  https://target.example.com

# Manual testing for IDOR
# Test parameter manipulation
curl -H "Authorization: Bearer $TOKEN" \
  "https://api.example.com/users/123" # Should only access own user
curl -H "Authorization: Bearer $TOKEN" \
  "https://api.example.com/users/456" # Test IDOR
```

#### A02:2021 - Cryptographic Failures

```bash
# SSL/TLS analysis with testssl.sh
docker run -it drwetter/testssl.sh https://target.example.com

# Check for weak ciphers
nmap --script ssl-enum-ciphers -p 443 target.example.com

# ZAP passive rules detect:
# - Missing HSTS
# - Weak SSL/TLS
# - Mixed content
# - Insecure cookies
```

#### A03:2021 - Injection

```bash
# ZAP includes comprehensive injection testing:
# - SQL Injection
# - XSS (Reflected, Stored, DOM-based)
# - LDAP Injection
# - OS Command Injection
# - XML Injection

# SQLMap for advanced SQL injection
sqlmap -u "https://target.example.com/search?q=test" --batch --forms
```

#### A04:2021 - Insecure Design

Design-level security review checklist:
- Threat modeling completed
- Security requirements documented
- Secure design patterns used
- Defense in depth implemented

#### A05:2021 - Security Misconfiguration

```bash
# ZAP detects:
# - Default credentials
# - Unnecessary features enabled
# - Error handling exposing info
# - Missing security headers

# Additional header checks
curl -I https://target.example.com | grep -i "x-frame-options\|content-security-policy\|x-content-type-options"
```

#### A06:2021 - Vulnerable Components

```bash
# Retire.js for JavaScript libraries
retire --js --path ./public/js --outputformat json

# ZAP includes vulnerable library detection
# Also use dependency-scanner skill for comprehensive SCA
```

#### A07:2021 - Authentication Failures

ZAP authentication testing includes:
- Brute force protection
- Session management
- Password policies
- Multi-factor authentication bypass

#### A08:2021 - Software and Data Integrity Failures

Checks for:
- CI/CD pipeline security
- Unsigned updates
- Deserialization vulnerabilities

#### A09:2021 - Security Logging Failures

Review:
- Audit logging implementation
- Log injection vulnerabilities
- Log storage security

#### A10:2021 - Server-Side Request Forgery

```bash
# ZAP SSRF detection through active scanning
# Manual testing
curl "https://target.example.com/fetch?url=http://169.254.169.254/latest/meta-data/"
```

### ZAP-MCP Features

- Automated scan initiation
- Result parsing and analysis
- AI-powered vulnerability assessment
- Remediation guidance generation

## Best Practices

### Scanning Strategy

1. **Baseline First** - Start with passive baseline scan
2. **Scope Definition** - Define clear target scope
3. **Authentication** - Configure proper auth for full coverage
4. **Rate Limiting** - Respect target rate limits
5. **Exclude Sensitive** - Exclude logout, delete, payment endpoints

### Scan Configuration

```yaml
# zap-baseline.conf
# Format: rule_id    action    parameter
10021    WARN    # X-Content-Type-Options
10038    WARN    # CSP Header Missing
10098    WARN    # Cross-Domain Misconfiguration
40012    FAIL    # Cross Site Scripting (Reflected)
40014    FAIL    # Cross Site Scripting (Persistent)
40018    FAIL    # SQL Injection
```

### CI/CD Integration

```yaml
# GitHub Actions example
name: OWASP Security Scan
on: [push, pull_request]

jobs:
  zap-scan:
    runs-on: ubuntu-latest
    steps:
      - name: ZAP Baseline Scan
        uses: zaproxy/action-baseline@v0.10.0
        with:
          target: 'https://staging.example.com'
          rules_file_name: '.zap-rules.tsv'

      - name: Upload Report
        uses: actions/upload-artifact@v3
        with:
          name: zap-report
          path: report_html.html
```

      "evidence": "Error message: SQL syntax error"
    }
  ],
  "artifacts": ["full-scan-report.json", "owasp-report.html"]
}
```

## Error Handling

### Common Issues

| Error | Cause | Resolution |
|-------|-------|------------|
| `Connection refused` | Target not reachable | Verify target URL and network |
| `Authentication failed` | Invalid credentials | Check auth configuration |
| `Scan timeout` | Large application | Increase timeout or scope |
| `Rate limited` | Too aggressive | Adjust scan speed settings |

## Constraints

- Always obtain proper authorization before scanning
- Never scan production systems without approval
- Configure appropriate scan speeds for target infrastructure
- Exclude destructive actions (logout, delete) from scope
- Respect rate limits and server capacity
- Document all findings with remediation guidance
