DevSecOps
Integration of security practices into software development and deployment pipelines, implementing automated security testing, vulnerability management, and secure infrastructure deployment methodologies.
Overview
DevSecOps represents the integration of security practices within the DevOps process, emphasizing security automation, continuous security testing, and infrastructure security. This category focuses on embedding security controls throughout the software development lifecycle, from code commit to production deployment.
Core Competencies
Static Application Security Testing (SAST)
Automated source code analysis to identify security vulnerabilities, coding standard violations, and potential security flaws before deployment.
Tools and Techniques:
- Semgrep: Multi-language pattern-based code analysis
- Bandit: Python security linter
- SonarQube: Code quality and security platform
- Custom security rule development
Dynamic Application Security Testing (DAST)
Runtime application security testing to identify vulnerabilities in deployed applications through black-box testing methodologies.
Capabilities:
- OWASP ZAP: Automated web application scanning
- Burp Suite: Advanced security testing platform
- API security testing frameworks
- Authenticated application testing
Software Composition Analysis (SCA)
Identification and management of open-source components, dependencies, and associated security vulnerabilities.
Technologies:
- Snyk: Dependency vulnerability scanning
- Dependabot: GitHub dependency automation
- OWASP Dependency-Check: Software composition analysis
- Software Bill of Materials (SBOM) generation
Container Security
Security implementation for containerized applications, covering image scanning, runtime protection, and orchestration security.
Focus Areas:
- Trivy: Container vulnerability scanner
- Clair: Static vulnerability analysis
- Image signing and verification
- Container runtime security monitoring
Infrastructure as Code Security
Security validation of infrastructure code to prevent misconfigurations and ensure compliance before deployment.
Tools:
- Checkov: Multi-cloud IaC security scanner
- tfsec: Terraform security analysis
- Terrascan: Policy-as-code for infrastructure
- Cloud configuration compliance
