100 Days Plan -DevSecOps Mastery Plan

1. About DevSecOps

DevSecOps (Development, Security, and Operations) is an approach that embeds security into every stage of the software development lifecycle (SDLC). It ensures that security is not an afterthought but a continuous process throughout the CI/CD pipeline. By automating security checks, organizations can identify vulnerabilities early, reduce risks, and deliver secure software faster.

Key Areas of Focus:

• Shift Left Security : Introducing security earlier in the SDLC.
• Automated Security Testing : Tools like SAST (Static Application Security Testing), DAST (Dynamic Application Security Testing), and SCA (Software Composition Analysis).
• Infrastructure as Code (IaC) Security : Securing cloud infrastructure using tools like Terraform and AWS CloudFormation.
• Container Security : Scanning Docker images and Kubernetes clusters for vulnerabilities.
• Compliance & Governance : Ensuring adherence to security policies and regulations.

Key Tools:

• CI/CD Pipelines : Jenkins, GitLab CI/CD, GitHub Actions.
• Security Testing : SonarQube, OWASP ZAP, Burp Suite.
• Container Security : Aqua Security, Anchore, Trivy.
• Cloud Security : AWS Security Hub, Azure Security Center, GCP Security Command Center.

2. Why Learn DevSecOps?

• High Demand : Organizations need DevSecOps professionals to integrate security into their DevOps pipelines.
• Career Growth : Lucrative salaries and opportunities in DevOps and cybersecurity.
• Critical Skill : Essential for delivering secure software in fast-paced environments.
• Certifications : Gain industry-recognized certifications like Certified DevSecOps Professional (CDP), AWS Certified Security, or Kubernetes Security Specialist (CKS).
• Real-World Impact : Help prevent breaches, reduce vulnerabilities, and ensure compliance with security standards.
