Infrastructure drift refers to the difference between what's defined in your Infrastructure as Code (IaC) configuration and the real-time state of infrastructure in the cloud. This can be caused by human input, poor configuration, applications making unwanted changes, or other factors. Drift detection is a continuous process that identifies deviations from IaC configurations that pose security risks to organizations. If left unmanaged, drift can lead to data breaches, application downtime, and deployment failures. However, with effective drift management, organizations can standardize infrastructure setup, reduce errors, and improve security controls. A comprehensive approach to IaC security includes increasing IaC coverage, adopting a tool for scanning configurations during development and build pipelines, leveraging IaC to detect synchronized infrastructure, employing an open-source drift detection tool, taking action on findings, and closing the feedback loop. When choosing a drift management tool, consider factors such as access levels and least-privileged policies to ensure effective security.
