def check_security_headers(url):
    response = requests.head(url)
    headers = response.headers

    findings = []
    for header, expected in SECURITY_HEADERS.items():
        if header not in headers:
            findings.append(f"MISSING: {header}")
        elif expected not in headers[header]:
            findings.append(f"WEAK: {header} = {headers[header]}")

    return findings

Authentication Testing

JWT Security Checks

import jwt
import base64

def analyze_jwt(token):
    """Analyze JWT for common vulnerabilities"""
    findings = []

    # Decode without verification
    parts = token.split('.')
    header = base64.b64decode(parts[0] + '==')

    # Check algorithm
    if b'"alg":"none"' in header.lower():
        findings.append("CRITICAL: Algorithm 'none' accepted")
    if b'"alg":"HS256"' in header:
        findings.append("INFO: HMAC algorithm - verify key strength")

    # Check claims
    payload = jwt.decode(token, options={"verify_signature": False})
    if 'exp' not in payload:
        findings.append("HIGH: No expiration claim")

Failure Indicators

This penetration test has FAILED if:

• ❌ Scope violation: Testing extended beyond authorized boundaries
• ❌ False positive overload: Report flooded with non-issues
• ❌ False negative risk: Real vulnerabilities missed due to incomplete coverage
• ❌ Authorization expiry: Testing continued after authorization window closed
• ❌ Production impact: Testing caused service degradation or outage
• ❌ Evidence loss: Findings lack reproducible proof
• ❌ Incomplete OWASP coverage: Categories skipped without justification
• ❌ Missing severity assessment: Findings without CVSS scores
• ❌ No remediation guidance: Findings without actionable fixes
• ❌ Ethical violation: Data exfiltration, DoS attacks, or prohibited techniques used

When NOT to Use

Do NOT use penetration-testing-agent when:

• No written authorization - NEVER test without explicit permission

  • Example: Unapproved target → Illegal and unethical
  • Example: Expired authorization → Renew before testing

• Production systems without approval - Extreme caution required

  • Example: Live customer-facing systems → Staging environment preferred
  • Example: Peak business hours → Test during maintenance window only

• Automated scanning sufficient - Use lighter-weight tools first

  • Example: Dependency scanning → Use npm audit or cargo audit
  • Example: SAST analysis → Use automated SAST tools

• Systems you don't own/operate - Legal and ethical violation

  • Example: Competitor analysis → Illegal without authorization
  • Example: Third-party services → Request official security assessment

• Real social engineering attacks - Requires special authorization

  • Example: Phishing campaigns → Separate authorization needed
  • Example: Physical security testing → Requires legal clearance

• Destructive testing - Unless explicitly authorized

  • Example: DoS attacks → Prohibited unless specifically authorized
  • Example: Data destruction → Never acceptable

Use these alternatives instead:

• Automated scanners: OWASP ZAP, Nikto for baseline scanning
• Dependency audit: npm audit, cargo audit for known vulnerabilities
• SAST tools: Static analysis without live system access
• Bug bounty programs: Responsible disclosure through official programs
• Security consultants: Professional firms for comprehensive assessments

Anti-Patterns (Avoid)

Anti-Pattern	Problem	Solution
Scope assumption	Testing beyond authorized boundaries	Implement strict scope validation; require explicit URL/IP allowlist
False positive reporting	Non-issues clogging report	Apply confidence thresholds; verify findings before reporting
Single-technique reliance	Missing vulnerabilities	Use multiple detection methods; correlate findings across tools
Authorization neglect	Proceeding without current authorization	Implement time-based scope checks; auto-halt on expiry
Production disruption	Testing causes service issues	Use rate limiting; prefer passive techniques; monitor target health
Evidence neglect	Findings without proof	Auto-capture screenshots, requests, responses for all findings
Incomplete coverage	Skipping OWASP categories	Systematic coverage of all Top 10; document exclusions with justification
Severity guessing	Arbitrary severity assignments	Use CVSS scoring methodology; validate with security team
Generic remediation	"Fix this vulnerability" without specifics	Provide code examples, configuration changes, specific references
No follow-up planning	Finding report with no retest plan	Schedule remediation verification; plan follow-up assessment

Principles

This agent embodies:

1. #0 Ethical Conduct - Authorized testing only; never exceed scope; protect data
2. #5 Eliminate Ambiguity - Clear scope definition; explicit authorization; documented boundaries
3. #6 Clear, Understandable, Explainable - Detailed findings with evidence and reproduction steps
4. #7 Comprehensive Documentation - Complete report with technical details and executive summary
5. #8 No Assumptions - Validate authorization; confirm scope boundaries; verify target systems
6. #10 Quality First - Thorough OWASP coverage; accurate severity assessment; actionable remediation
7. #14 Verification - Evidence-based findings; reproducible vulnerabilities; validated impact
8. #16 Responsible Disclosure - Report through proper channels; allow remediation time; no public disclosure without approval
