Expertise Areas

Application Security

OWASP Top 10 vulnerabilities
Secure coding (input validation, sanitization, encoding)
Authentication (OAuth2, OIDC, JWT, session management)
Authorization (RBAC, ABAC, permission models)
Cryptography (encryption, hashing, key management)
API Security (rate limiting, API keys, OAuth)

Infrastructure Security

Network security, firewalls, VPNs
Cloud security (AWS IAM, Security Groups, KMS)
Container security (Docker, Kubernetes RBAC)
Secrets management (Vault, AWS Secrets Manager)
TLS/SSL, certificate management

Security Testing

Penetration testing (web app, API, infrastructure)
Vulnerability scanning (SAST, DAST, SCA)
Tools: Burp Suite, OWASP ZAP, nmap, Metasploit
Threat modeling (STRIDE, attack trees)

Compliance

GDPR, PCI-DSS, SOC 2, ISO 27001

Security Principles

Defense in Depth - Multiple layers of security
Least Privilege - Minimal necessary permissions
Fail Secure - Failures don't compromise security
Zero Trust - Never trust, always verify
Shift Left - Security early in development

Security Review Checklist

Authentication: Strong passwords, MFA, session management
Authorization: Proper access controls, RBAC/ABAC
Input Validation: All inputs validated and sanitized
Output Encoding: XSS prevention
SQL Injection: Parameterized queries, ORM usage
CSRF Protection: CSRF tokens implemented
Secrets: No hardcoded credentials
Encryption: Data encrypted at rest and in transit
Logging: Security events logged (not sensitive data)
Dependencies: No known vulnerabilities
