Core Principles of DevSecOps

DevSecOps is a cultural and technical movement that integrates security practices into the DevOps process. It emphasizes collaboration, automation, and continuous improvement to ensure security is a shared responsibility across development, operations, and security teams.

These principles guide the implementation and culture of DevSecOps:

a. Shift Left: Security Early and Often

• Concept: Integrate security considerations and testing as early as possible in the software development lifecycle (SDLC). Don't wait until the pre-production or deployment phase.
• Actions:
  • Security requirements definition during planning.
  • Threat modeling during design.
  • Static Application Security Testing (SAST) during coding.
  • Security training for developers.
  • Secure code reviews.

b. Automation: Security at Speed

• Concept: Automate security checks, tests, and processes to match the speed of DevOps. Manual security processes are too slow for modern CI/CD pipelines.
• Actions:
  • Automated SAST, DAST (Dynamic Application Security Testing), IAST (Interactive Application Security Testing) in CI/CD pipelines.
  • Automated vulnerability scanning for dependencies and containers.
  • Automated compliance checks.
  • Automated security patching and configuration management.

c. Continuous Integration/Continuous Delivery (CI/CD) Security

• Concept: Embed security controls and tests directly into the CI/CD pipeline. Every code commit and build should trigger automated security evaluations.
• Actions:
  • Security gates in the pipeline (e.g., fail build if critical vulnerabilities are found).
  • Secrets management integration.
  • Container image scanning before deployment.
  • Infrastructure as Code (IaC) scanning.

d. Security as Code: Manage Security Like Software

• Concept: Define and manage security policies, configurations, and compliance requirements using code and version control, just like application or infrastructure code.
• Actions:
  • Security policies written in machine-readable formats (e.g., YAML, JSON).
  • Version control for security configurations (e.g., firewall rules, IAM policies).
  • Automated deployment and enforcement of security policies.
  • Using tools like Open Policy Agent (OPA).

e. Collaboration and Communication: Breaking Down Silos

• Concept: Foster strong collaboration and shared responsibility for security among development, security, and operations teams. Security is everyone's job.
• Actions:
  • Cross-functional teams.
  • Regular communication channels and feedback loops.
  • Shared security dashboards and metrics.
  • Security champions program within development teams.

f. Threat Modeling: Proactive Risk Identification

• Concept: Systematically identify potential threats, vulnerabilities, and attack vectors for an application or system during the design and development phases.
• Actions:
  • Regular threat modeling sessions for new features and major changes.
  • Using methodologies like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege).
  • Documenting and mitigating identified threats.

g. Least Privilege: Minimize Attack Surface

• Concept: Grant only the minimum necessary permissions and access rights to users, systems, and services to perform their tasks.
• Actions:
  • Role-Based Access Control (RBAC).
  • Regular access reviews and audits.
  • Just-In-Time (JIT) access.
  • Network segmentation.

  • Endpoint security.
  • Data encryption at rest and in transit.
