What is DevSecOps?

Back to learning

DevSecOps is a methodology that integrates security practices into every stage of the software development lifecycle. By embedding security into DevOps workflows, organisations can deliver secure applications at the speed and scale required by modern digital business.

Core Principles

Shift-Left Security

Shift-left security identifies and addresses security issues early in development when they're less expensive to fix, including security requirements definition, threat modelling, and automated testing.

Security as Code

Security as Code treats security policies and controls as code that can be version controlled, automatically deployed, and programmatically validated.

Continuous Monitoring

Real-time security monitoring throughout the application lifecycle with automated threat detection, continuous compliance validation, and integrated security metrics.

Key Practices

CI/CD Security Integration

DevSecOps integrates security into CI/CD pipelines through:

• SAST: Static application security testing for code vulnerabilities
• DAST: Dynamic security testing of running applications
• SCA: Software composition analysis for third-party component vulnerabilities
• Infrastructure Scanning: Validation of infrastructure configurations

Infrastructure Security

Infrastructure as Code security ensures secure-by-default deployments with automated compliance validation and container security scanning.

Implementation

Cultural Transformation

Successful DevSecOps requires:

• Shared Responsibility: Security becomes everyone's responsibility
• Cross-Functional Teams: Teams with integrated security expertise
• Security Champions: Developers who advocate security within teams
• Continuous Learning: Ongoing security training programs

Modern Tools

Application Security Platforms provide DevSecOps-friendly features including API-first architecture, policy as code, automated response, and native DevOps integration.

Benefits

Security Improvements

• Early threat detection in the development cycle
• Secure-by-default configurations
• Automated incident response capabilities
• Consistent security practices across applications

Development Velocity

• Reduced manual security processes
• Security issues addressed during development
• Integrated continuous deployment validation
• Fewer security-related delays and rollbacks

DevSecOps enables organisations to deliver secure applications while maintaining development velocity through automation, cultural transformation, and integrated security platforms.
