Infrastructure as Code (IaC) security in DevSecOps ensures that infrastructure—like servers, networks, and configurations—is managed through code while embedding security controls at every stage. Instead of manually setting up systems, IaC uses templates and automation, reducing human error and enhancing consistency. Security policies, vulnerability scans, and compliance checks are integrated into the code pipeline itself. This means potential risks are detected early, preventing insecure deployments. Learning IaC security is vital for cloud-native environments where automation dominates. With proper DevSecOps Training, professionals can implement IaC securely, enforce standards, and streamline both agility and security in modern development workflows.
