Detailed Cycle Plan¶
CYCLE 1: Security Testing Fundamentals (~4,000 lines)¶
Topic 1: Security Testing Philosophy¶
What will be covered: - What is Security Testing?
Definition:
Security testing validates that ATP meets security requirements,
identifies vulnerabilities, and ensures compliance with security
standards and regulations.
Objectives:
1. Identify security vulnerabilities
2. Validate security controls (authentication, authorization, encryption)
3. Ensure compliance (SOC 2, GDPR, HIPAA, PCI DSS)
4. Validate tamper-evidence and integrity
5. Test multi-tenant isolation
6. Verify zero-trust architecture
7. Prevent security incidents
8. Provide audit evidence
ATP Focus:
- Authentication/authorization (JWT, OAuth, RBAC)
- Multi-tenant isolation (RLS, encryption, access control)
- Tamper-evidence (hash chains, signatures, WORM)
- Compliance (SOC 2, GDPR, HIPAA, PCI DSS)
- Encryption (at rest, in transit)
- Vulnerability prevention (OWASP Top 10)
-
Security Testing vs. Functional Testing
Functional Testing: - Tests: "Does it work correctly?" - Focus: Business requirements - Example: "Can user ingest audit event?" Security Testing: - Tests: "Can it be exploited?" - Focus: Security requirements - Example: "Can unauthorized user access audit data?" Relationship: - Security testing complements functional testing - Both required for production readiness - Security tests run in addition to functional tests -
Security Testing Pyramid
/\ / \ Penetration Testing (Manual) /____\ / \ DAST (Dynamic Analysis) /________\ / \ SAST (Static Analysis) /____________\ / \ Unit Security Tests (Automated) /________________\ Unit Security Tests (70%): - Fast, automated - Authentication/authorization logic - Encryption/decryption - Input validation - Example: "JWT token validation test" SAST (20%): - Source code scanning - Automated vulnerability detection - Security pattern matching - Example: "Hardcoded secrets detection" DAST (8%): - Runtime vulnerability scanning - API security testing - Web application scanning - Example: "OWASP ZAP scan" Penetration Testing (2%): - Manual security assessment - Exploit attempts - Red team exercises - Example: "Full penetration test (quarterly)" -
Security Testing Principles
1. Shift-Left Security - Test security as early as possible (development) - SAST in IDE, pre-commit hooks - Security tests in CI/CD 2. Defense in Depth - Multiple layers of security testing - Unit tests + SAST + DAST + Penetration testing - No single point of failure 3. Continuous Security Testing - Automated security tests in CI/CD - Regular dependency scanning - Continuous vulnerability monitoring 4. Compliance-Driven - Tests aligned with compliance requirements - SOC 2, GDPR, HIPAA controls validation - Audit-ready test evidence 5. Threat Model-Based - Tests based on threat model - Focus on high-risk areas - Attack surface coverage 6. Zero-Trust Validation - Test "never trust, always verify" - Validate all authentication/authorization - Test tenant isolation 7. Realistic Attack Scenarios - Test actual attack patterns - OWASP Top 10 coverage - Known vulnerability patterns

Topic 35: Security Testing Best Practices¶
What will be covered: - Best Practices Checklist
✅ DO:
- Test security as early as possible (shift-left)
- Automate security tests in CI/CD
- Test all authentication/authorization paths
- Validate multi-tenant isolation
- Test tamper-evidence mechanisms
- Regular dependency scanning
- OWASP Top 10 coverage
- Compliance control validation
- Regular penetration testing
- Security metrics tracking
❌ DON'T:
- Skip security tests for "quick fixes"
- Ignore "low severity" vulnerabilities
- Rely only on automated tools
- Test only happy paths
- Ignore false positives without investigation
- Skip compliance testing
- Forget to test tenant isolation
- Ignore dependency vulnerabilities
- Skip regular penetration testing
- Ignore security metrics trends
