Shift Left Security in DevSecOps

Introduction

Shift Left Security is a development approach that integrates security practices early in the software development lifecycle (SDLC). This proactive strategy aims to address security vulnerabilities and compliance requirements before they become costly issues later in the process.

Key Concepts

• Security as Code: Treating security policies and checks as code ensures they are versioned and reproducible.
• Continuous Integration/Continuous Deployment (CI/CD): Integrating security checks within CI/CD pipelines allows for early detection of vulnerabilities.
• Automation: Automated security testing tools help identify issues without manual intervention, improving efficiency.

Step-by-Step Process

The following flowchart outlines the key steps in implementing Shift Left Security:

Best Practices

1. Incorporate security training for developers to recognize potential vulnerabilities.
2. Utilize static application security testing (SAST) tools during the coding phase.
3. Implement dynamic application security testing (DAST) during runtime to detect issues in a live environment.
4. Run regular dependency checks to ensure third-party libraries are secure.
5. Employ runtime application self-protection (RASP) to monitor and protect applications in real-time.
