# Application Security & Secure Code Review
## Expertise
Comprehensive application security assessment and secure development lifecycle implementation, with focus on preventing vulnerabilities before they reach production.
## Secure Code Review
### Methodology
- **Static Analysis**: Automated scanning with tools like SonarQube, Semgrep, and Checkmarx
- **Manual Review**: In-depth examination of critical code paths and security controls
- **Threat Modeling**: STRIDE methodology for identifying potential attack vectors
- **Risk Assessment**: Prioritizing findings based on exploitability and business impact
### Common Vulnerability Classes
- **Injection Flaws**: SQL injection, command injection, XSS
- **Authentication Issues**: Broken auth, session management flaws
- **Access Control**: IDOR, privilege escalation, path traversal
- **Cryptographic Failures**: Weak algorithms, improper key management
- **Security Misconfigurations**: Default credentials, excessive permissions
## Security Testing
### Approaches
- **SAST (Static)**: Code-level vulnerability detection
- **DAST (Dynamic)**: Runtime security testing
- **IAST (Interactive)**: Hybrid approach combining SAST and DAST
- **Penetration Testing**: Real-world attack simulation
### Tools & Frameworks
- Burp Suite Pro for web application testing
- OWASP ZAP for automated scanning
- Custom scripts for specific vulnerability classes
- Continuous security testing in CI/CD pipelines
## Secure Development
### Security by Design
- Secure coding standards and guidelines
- Security champion programs
- Developer security training
- Security requirements in design phase
### DevSecOps Integration
- Security gates in CI/CD pipelines
- Automated vulnerability scanning
- Container and dependency scanning
- Infrastructure as Code security
## Achievements
- Identified and remediated critical vulnerabilities in production applications
- Implemented secure SDLC practices reducing vulnerabilities by 70%
- Led security training programs for development teams
- Established security review process for all production releases
