# Web Security Testing Workflow

## Overview

Specialized workflow for testing web applications against OWASP Top 10 vulnerabilities including injection attacks, XSS, broken authentication, and access control issues.

## When to Use This Workflow

Use this workflow when:
- Testing web application security
- Performing OWASP Top 10 assessment
- Conducting penetration tests
- Validating security controls
- Bug bounty hunting

## Workflow Phases

### Phase 1: Reconnaissance

#### Skills to Invoke
- `top-web-vulnerabilities` - OWASP knowledge

#### Actions
1. Map application surface
2. Identify technologies
3. Discover endpoints
4. Find subdomains
5. Document findings

#### Copy-Paste Prompts
```
```

### Phase 2: Injection Testing

#### Skills to Invoke

#### Actions
1. Test SQL injection
2. Test NoSQL injection
3. Test command injection
4. Test LDAP injection
5. Document vulnerabilities

#### Copy-Paste Prompts
```
```

```
```

### Phase 3: XSS Testing

#### Skills to Invoke

#### Actions
1. Test reflected XSS
2. Test stored XSS
3. Test DOM-based XSS
4. Test XSS filters
5. Document findings

#### Copy-Paste Prompts
```
```

### Phase 4: Authentication Testing

#### Skills to Invoke
- `broken-authentication` - Authentication testing

#### Actions
1. Test credential stuffing
2. Test brute force protection
3. Test session management
4. Test password policies
5. Test MFA implementation

#### Copy-Paste Prompts
```
Use @broken-authentication to test authentication security
```

### Phase 5: Access Control Testing

#### Skills to Invoke

#### Actions
1. Test vertical privilege escalation
2. Test horizontal privilege escalation
3. Test IDOR vulnerabilities
4. Test directory traversal
5. Test unauthorized access

#### Copy-Paste Prompts
```
```

```
```

### Phase 6: Security Headers

#### Skills to Invoke
- `security-and-hardening` - Security headers

#### Actions
1. Check CSP implementation
2. Verify HSTS configuration
3. Test X-Frame-Options
4. Check X-Content-Type-Options
5. Verify referrer policy

#### Copy-Paste Prompts
```
Use @security-and-hardening to audit security headers
```

### Phase 7: Reporting

#### Skills to Invoke
- `reporting-standards` - Security reporting

#### Actions
1. Document vulnerabilities
2. Assess risk levels
3. Provide remediation
4. Create proof of concept
5. Generate report

#### Copy-Paste Prompts
```
Use @reporting-standards to create security report
```
