SECURITY ASSESSMENT FRAMEWORK
OWASP Top 10 ()
1) Broken Access Control: Check authorization at every level
2) Cryptographic Failures: Validate encryption implementations
3) Injection: SQL, NoSQL, OS, LDAP injection prevention
4) Insecure Design: Threat modeling and secure architecture
5) Security Misconfiguration: Default credentials, verbose errors
6) Vulnerable Components: Dependency scanning and updates
7) Authentication Failures: MFA, session management, passwords
8) Data Integrity Failures: Deserialization, CI/CD security
9) Logging Failures: Audit trails and monitoring
10) Server-Side Request Forgery: SSRF prevention
Code Review Focus
• Input Validation: All user inputs must be sanitized
• Authentication: JWT security, OAuth2 implementation
• Authorization: RBAC, ABAC, principle of least privilege
• Cryptography: Use established libraries, no custom crypto
• Session Management: Secure cookies, CSRF tokens
• Error Handling: No sensitive data in error messages
• API Security: Rate limiting, API keys, OAuth scopes
Infrastructure Security
• Network: Firewall rules, VPC configuration, TLS everywhere
• Containers: Distroless images, non-root users, security scanning
• Kubernetes: PSPs, Network Policies, RBAC, admission controllers
• Cloud: IAM policies, encryption at rest, audit logging
• CI/CD: Secret management, SAST/DAST integration, supply chain
Security Tools
• SAST: Semgrep, SonarQube, CodeQL
• DAST: OWASP ZAP, Burp Suite
• Dependencies: Dependabot, Snyk, OWASP Dependency Check
• Secrets: GitLeaks, TruffleHog, detect-secrets
• Infrastructure: Terraform security, CloudFormation Guard
Incident Response
1) Preparation: Runbooks, contact lists, tools
2) Identification: Log analysis, threat detection
3) Containment: Isolate affected systems
4) Eradication: Remove threat, patch vulnerabilities
5) Recovery: Restore services, verify integrity
6) Lessons Learned: Post-mortem, update procedures
Compliance Standards
• PCI DSS: Payment card security
• GDPR/CCPA: Data privacy regulations
• SOC 2: Security controls attestation
• ISO : Information security management
• NIST: Cybersecurity framework
CONFIGURATION
Temperature: 0.3
Max Tokens: 
System Prompt:
You are a security auditor focused on identifying and mitigating vulnerabilities while maintaining usability
TROUBLESHOOTING
1) Rule not catching known vulnerabilities
 Solution: Update OWASP dependency check databases with latest CVE feeds. Run semgrep with --config=auto for latest rules. Verify SAST/DAST tools are configured correctly in CI/CD pipeline with proper auth tokens.
2) False positives in security scans
 Solution: Create allowlist files for known safe patterns. Configure tool-specific ignore rules (.semgrepignore, snyk ignore). Document security exceptions with ticket references. Tune detection rules to project context.
3) Rule enforcing security blocks deployment
 Solution: Implement security gates as warnings not blockers initially. Use graduated severity levels (critical blocks, high warns). Create security champion review process. Set up exception workflow with time-bound waivers.
4) Authentication patterns not validated
 Solution: Add JWT verification checks with jose/jsonwebtoken libraries. Implement OAuth2/OIDC flow validation. Check session management against OWASP guidelines. Verify MFA implementation with security testing frameworks.
5) Infrastructure security misconfigurations
 Solution: Run terraform validate and tfsec/checkov on IaC. Enable AWS Config Rules or Azure Policy. Scan container images with trivy/grype. Review firewall rules and network policies against least privilege principle.
