            "xss": self._check_xss(system),
            "command": self._check_command_injection(system)
        }

3. Protocol Analysis

Analysis System

class WebProtocolAnalyzer:
    def __init__(self):
        self.protocols = {
            "http": ["http", "https", "http2"],
            "security": ["ssl", "tls", "certificates"],
            "authentication": ["oauth", "saml", "jwt"]
        }
    
    def analyze_protocols(self, system: str):
        # Protocol analysis
        results = {}
        for protocol_type, protocols in self.protocols.items():
            results[protocol_type] = self._analyze_protocols(system, protocols)
        return self._compile_analysis(results)
    
    def _analyze_protocols(self, system: str, protocols: list):
        # Protocol analysis
        return {
            "implementation": self._check_implementation(system, protocols),
            "security": self._check_security(system, protocols),
            "performance": self._check_performance(system, protocols)
        }

4. Penetration Testing

Testing System

class WebPenetrationTester:
    def __init__(self):
        self.test_phases = {
            "reconnaissance": self._perform_reconnaissance,
            "analysis": self._perform_analysis,
            "exploitation": self._perform_exploitation,
            "post_exploitation": self._perform_post_exploitation
        }
    
    def test_web_system(self, system: str):
        # Penetration testing
        results = {}
        for phase, test_func in self.test_phases.items():
            results[phase] = test_func(system)
        return self._compile_report(results)

        # Exploitation phase
        return {
            "app_exploitation": self._exploit_app(system),
            "server_exploitation": self._exploit_server(system),
            "data_exploitation": self._exploit_data(system)
        }

    def __init__(self):
        self.findings = []
        self.reports = []
        self.recommendations = []
    
    def document_finding(self, finding: dict):
        # Documenting a finding
        self.findings.append({
            "id": self._generate_id(),
            "type": finding["type"],
            "severity": finding["severity"],
            "description": finding["description"],
            "impact": self._assess_impact(finding),
            "reproduction": self._document_reproduction(finding),
            "remediation": self._suggest_remediation(finding)
        })
    
    def generate_report(self, format: str = "pdf"):
        # Report generation
        report = {
            "summary": self._generate_summary(),
            "technical_details": self._compile_details(),
            "findings": self._compile_findings(),
            "recommendations": self._compile_recommendations()
        }
        return self._export_report(report, format)
