Zero Trust CI/CD: Keyless Bitbucket Deployment on Google Cloud
Using static Service Account (SA) keys in CI/CD pipelines has long been a common method for authenticating to Google Cloud Platform (GCP). However, storing long-lived credentials inside external pipeline environment variables introduces severe security vulnerabilities and ongoing operational friction. Google Mandiant demonstrated in a threat intelligence blog post ( Holes in Your Bitbucket: Why…
This article discusses the security risks associated with using static Service Account keys for authenticating to Google Cloud Platform (GCP) in Bitbucket CI/CD pipelines and how Workload Identity Federation (WIF) provides a modern, keyless authentication mechanism. It explains the benefits of WIF, which include short-lived token exchange, fine-grained scope control, and reduced security risks.
The article outlines the steps required to enable WIF in GCP projects, including creating a Workload Identity Pool and Provider, mapping Bitbucket identity to a GCP Service Account and granting necessary permissions.
