Knowledge Base Intro

This knowledge base covers essential DevSecOps concepts, tools, and best practices for building secure, scalable, and maintainable systems. Explore the sections below to deepen your understanding of modern software development and operations.

What is DevSecOps?​

DevSecOps extends traditional DevOps practices by integrating security at every phase of the software development lifecycle. Rather than treating security as an afterthought, DevSecOps embeds security controls, testing, and validation throughout the development pipeline.

Core Principles​

Shift Left Security: Identify and address security issues early in development rather than waiting for production deployment. This includes static code analysis, dependency scanning, and security-focused code reviews.

Automation First: Automate security testing, vulnerability scanning, and compliance checks within CI/CD pipelines to maintain consistent security postures without manual intervention.

Shared Responsibility: Security becomes a collective responsibility across development, operations, and security teams rather than being siloed in a separate security department.

Continuous Monitoring: Implement real-time security monitoring and logging to detect anomalies, unauthorized access attempts, and potential breaches in production systems.

Key Security Practices​

Static Application Security Testing (SAST): Analyze source code for security vulnerabilities before runtime. Tools like SonarQube, Checkmarx, and Semgrep scan code for common security flaws including injection vulnerabilities, authentication issues, and insecure configurations.

Dynamic Application Security Testing (DAST): Test running applications to identify security vulnerabilities that only appear during execution. Tools like OWASP ZAP and Burp Suite simulate attacks against live applications.

Software Composition Analysis (SCA): Scan third-party libraries and dependencies for known vulnerabilities. Tools like Snyk, Dependabot, and OWASP Dependency-Check maintain databases of CVEs and provide automated alerts for vulnerable components.

Container Security: Scan container images for vulnerabilities, misconfigurations, and embedded secrets. Tools like Trivy, Aqua Security, and Anchore analyze container layers and identify security risks before deployment.

Infrastructure as Code Security: Validate infrastructure configurations for security misconfigurations, exposed credentials, and compliance violations. Tools like Checkov, tfsec, and Terraform Sentinel enforce security policies on infrastructure definitions.

Secrets Management: Never store credentials, API keys, or certificates in source code or configuration files. Use dedicated secret management solutions like HashiCorp Vault, AWS Secrets Manager, or Azure Key Vault to secure sensitive data.

Security in CI/CD Pipelines​

Integrate security gates at each pipeline stage:

  1. Pre-commit hooks validate code quality and scan for secrets before commits reach version control
  2. Build stage runs SAST tools and dependency scans to catch vulnerabilities early
  3. Test stage executes security-focused unit and integration tests
  4. Container image scanning validates base images and runtime configurations
  5. Pre-deployment DAST testing validates application security in staging environments
  6. Runtime security monitoring detects anomalies and unauthorized activities in production

Compliance and Governance​

DevSecOps practices support regulatory compliance requirements including GDPR, HIPAA, PCI-DSS, and SOC 2. Automated compliance checks ensure systems meet security standards consistently:

Policy as Code: Define security policies in code using tools like Open Policy Agent (OPA) to enforce consistent security controls across all environments.

Audit Trails: Maintain comprehensive logs of all system activities, configuration changes, and security events for compliance auditing and incident investigation.

Access Control: Implement principle of least privilege and role-based access control (RBAC) to limit user permissions to only what is necessary for their role.
