What is Policy as Code (PaC) & How Do You Implement It?

Policy as code (PaC) is a method of defining and enforcing policies through code, stored and managed in a centralized policy engine. It helps maintain security, compliance, and operational standards in large-scale deployments by automating the management of policies. Key benefits include efficiency, consistency, speed, governance and compliance, visibility, collaboration, version control, and reduced configuration drift. Implementing PaC involves gathering data, choosing a suitable tool, writing policies as code, integration testing, deployment, monitoring, and setting up governance processes for future changes. Open Policy Agent (OPA) is an example of a popular policy management tool that implements policies using the Rego language.
