DevSecOps Pillar 3: Pragmatic Implementation – Building Scalable, Secure Workflows
Introduction
For business leaders, adopting DevSecOps must balance security with development speed. The Cloud Security Alliance's third pillar, Pragmatic Implementation, emphasizes practical, scalable approaches to embed security into software development without overwhelming teams. In this third post of our seven-part series, we explore the tools, processes, and workflows that make DevSecOps achievable, ensuring your organization delivers secure software efficiently.
What is Pragmatic Implementation?
Pragmatic Implementation focuses on selecting tools and processes that align with your organization's maturity, size, and goals. Instead of adopting complex, one-size-fits-all solutions, this pillar advocates starting small, iterating, and scaling security practices sensibly. As outlined in the CSA's Six Pillars of DevSecOps, it's about integrating security into existing workflows without disrupting development, ensuring teams can adopt practices incrementally while maintaining agility.
Key Tools for Pragmatic Implementation
SAST (Static Application Security Testing)
Scans source code for vulnerabilities during development, catching issues early without slowing coding.
SCA (Software Composition Analysis)
Analyzes open-source components to identify known vulnerabilities, ensuring third-party code is secure.
DAST (Dynamic Application Security Testing)
Tests running applications to uncover runtime vulnerabilities, complementing static scans.
Container Security Tools
Scan container images for misconfigurations or vulnerabilities, critical for cloud-native environments.
IaC Scanning (Infrastructure as Code)
Validates cloud infrastructure templates to prevent insecure configurations before deployment.
Processes to Enable Success
Incremental Adoption
Start with one tool (e.g., SAST) in a single pipeline, then expand to others as teams gain confidence.
Risk-Based Prioritization
Focus on high-impact vulnerabilities (e.g., OWASP Top 10) to address critical risks without overwhelming developers.
Shift-Left Security
Embed security checks early in the development cycle, such as during code commits, to reduce rework.
Feedback Loops
Create channels for developers and security teams to review findings and refine processes, ensuring continuous improvement.
Workflows for Seamless Integration
CI/CD Integration
Embed SAST and SCA into CI/CD pipelines to automate security scans during builds, providing real-time feedback to developers.
Pre-Commit Checks
Use linters or lightweight scans in developer IDEs to catch issues before code is committed.
Sprint Integration
Include security tasks in sprint planning, such as reviewing SCA results, to align with development goals.
Automated Remediation
Configure tools to suggest fixes (e.g., updated libraries) and integrate with ticketing systems for tracking.
Real-world Example
Etsy scaled DevSecOps by starting with automated SAST in their CI/CD pipeline, enabling developers to address vulnerabilities during coding, which supported their 50+ daily deployments.
Conclusion
Pragmatic Implementation ensures DevSecOps is practical and scalable, embedding security into workflows without disrupting development. By choosing the right tools and processes, you empower teams to build secure software efficiently. Next, we'll explore Bridging Compliance and Development.
