To configure GCP IAM least privilege, create service accounts with minimal permissions and avoid assigning basic roles to minimize risk. This approach restricts identity access across multiple projects by applying security guardrails and validation.

The best way to manage GCP secrets without environment variables is enabling Secret Manager to centralize storage and access controls. This prevents hardcoded secrets and establishes secure rotation practices across your cloud deployments.

To set up a custom VPC with deny-by-default firewall rules, design quarantined networks instead of using the default VPC. This approach secures network traffic and allows configuring specific connectors for services like Cloud Run.

GCP does not strictly require a custom VPC for Cloud Run, but using a quarantined custom VPC with deny-by-default rules is a security best practice. This configuration avoids anti-patterns associated with the default network and secures connectors.

You should avoid basic roles and the default VPC in GCP because they are permissive anti-patterns that increase security risk. Replacing them with least privilege IAM and quarantined custom networks minimizes manual overhead and secures resources.
