  - Error handling and logging
  - Data protection
  - System configuration

  - FIO series (File I/O)

### Error Handling Examples

#### Python
```python
# Bad: Exposing stack trace
try:
    result = dangerous_operation()
except Exception as e:
    return f"Error: {str(e)}", 500

# Good: Generic error message
try:
    result = dangerous_operation()
except Exception as e:
    logger.error(f"Operation failed: {str(e)}")
    return "An error occurred. Please contact support.", 500
```

#### Java
```java
// Bad: Verbose exception
public void processRequest(String id) throws Exception {
    if (!isValid(id)) {
        throw new Exception("Invalid ID: " + id + " in database table users");
    }
}

// Good: Generic exception
public void processRequest(String id) throws Exception {
    if (!isValid(id)) {
        logger.error("Invalid ID provided: " + id);
        throw new InvalidInputException("Invalid request parameter");
    }
}
```

#### PHP
```php
// Bad: Displaying errors
ini_set('display_errors', 1);
error_reporting(E_ALL);

// Good: Logging errors
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ALL);
```

### Information Disclosure in Bug Bounties

#### Typical Scope
- Exposed .git repositories
- Backup file disclosure
- API key leakage
- Error message information
- Version disclosure

#### Severity Ratings
- **Critical:** Database credentials, admin passwords, API keys with full access
- **High:** Source code disclosure, authentication bypass via headers
- **Medium:** Framework version disclosure (if actively exploitable)
- **Low:** Server version headers, verbose errors without sensitive data
- **Informational:** Generic version information

#### Best Practices for Reporting
1. **Proof of Concept:** Show exactly what's disclosed
2. **Impact Analysis:** Explain potential exploitation
3. **Reproduction Steps:** Clear, detailed steps
4. **Remediation:** Suggest fixes
5. **Responsible Disclosure:** Don't download entire databases
