Overview: Security as Code (SaC)

Quick Definition

Security as Code is a cybersecurity approach that integrates security controls and policies directly into software development workflows. This methodology treats security configurations, policies, and compliance requirements as code that can be version-controlled, automated, and consistently deployed alongside application code.

In Security as Code implementations, security measures are defined using declarative languages, scripts, or configuration files that specify security requirements, access controls, vulnerability scanning parameters, and compliance policies. These security definitions are stored in version control systems alongside application code, enabling teams to track changes, collaborate on security improvements, and maintain consistency across environments.

The approach enables automatic enforcement of security policies during the software development lifecycle, from code commits through deployment. Security configurations can be tested, validated, and deployed using the same continuous integration and continuous deployment (CI/CD) pipelines used for application code.

Benefits include reduced human error, improved consistency across environments, faster incident response through automated remediation, and better collaboration between development and security teams. Security as Code also supports compliance efforts by providing auditable trails of security policy changes and implementations, making it easier to demonstrate adherence to regulatory requirements and security frameworks.
