Infrastructure as Code (IaC) is a cloud-computing practice that involves managing and provisioning cloud resources through machine-readable code, typically using YAML or JSON files, to ensure efficient and consistent deployment. While IaC offers advantages such as automation and scalability, it also introduces security risks, including hardcoded secrets, elevated privileges, and insecure defaults. To mitigate these risks, adopting a DevSecOps mindset, applying security best practices, and utilizing tools like AWS Secrets Manager and IDE security plugins are crucial. This approach incorporates security into the development pipeline, reducing vulnerabilities and ensuring compliance with standards. Tools like Bridgecrew and Tenable CS provide comprehensive security checks throughout the IaC lifecycle, enhancing the security posture by identifying and addressing flaws early.
