DevSecOps Pillar 5: Automation – Scaling Security with Efficiency
Introduction
For business leaders, securing software at the pace of modern development demands efficiency. The Cloud Security Alliance's fifth pillar, Automation, embeds security into the software development lifecycle (SDLC) by leveraging automated tools and workflows to reduce errors and accelerate delivery. In this fifth post of our seven-part series, we explore the tools, processes, and workflows that make automation the backbone of DevSecOps, enabling your organization to deliver secure software seamlessly.
What is Automation in DevSecOps?
Automation integrates security checks into development pipelines, minimizing manual effort and catching issues early. As outlined in the CSA's Six Pillars of DevSecOps, this pillar uses tools to scan code, monitor environments, and enforce policies in real time, ensuring security keeps pace with agile workflows. By automating repetitive tasks, teams focus on innovation while maintaining robust security and compliance.
Key Tools for Automation
SAST (Static Application Security Testing)
Automatically scans source code for vulnerabilities during development, identifying issues before deployment.
SCA (Software Composition Analysis)
Scans open-source libraries and other dependencies for known vulnerabilities or licensing issues, ensuring secure dependencies.
DAST (Dynamic Application Security Testing)
Tests running applications for runtime vulnerabilities, complementing static scans.
Container Security Tools
Automatically scan container images for misconfigurations or vulnerabilities in cloud-native environments.
IaC Scanning (Infrastructure as Code)
Validates cloud infrastructure templates to prevent insecure deployments.
Processes to Enable Automation
Shift-Left Security
Automate security checks early in the SDLC, such as during code commits, to reduce rework.
Continuous Integration
Embed automated scans into every build to catch vulnerabilities in real time.
Prioritized Remediation
Use automation to flag high-risk issues (e.g., OWASP Top 10) for immediate attention.
Feedback Loops
Configure tools to provide actionable insights (e.g., suggested fixes) to developers, streamlining resolution.
Workflows for Seamless Automation
CI/CD Pipeline Integration
Embed SAST, SCA, and DAST into CI/CD pipelines for automatic scans at each commit or build.
Pre-Commit Checks
Use IDE plugins to run lightweight scans before code is committed, catching issues early.
Automated Remediation
Configure tools to suggest or apply fixes, like updating vulnerable libraries, directly in workflows.
Monitoring Dashboards
Provide real-time visibility into scan results, empowering teams to act quickly.
Real-world Example
Spotify, a leading audio streaming platform, automates security scans in its CI/CD pipelines using SAST and SCA, enabling rapid feature releases while maintaining security across thousands of daily deployments.
Conclusion
Automation empowers DevSecOps by embedding security into fast-paced development without manual overhead. By leveraging automated tools and streamlined workflows, teams deliver secure, high-quality software efficiently. Next, we'll explore Measure, Monitor, Report, and Action.
