Setting this up goes beyond policies regarding secrets; it should include hardening the full IAM setup, as it could otherwise allow for privilege escalation attacks. Ensure you never allow open \"pass role\" privileges or unrestricted IAM creation privileges, as these can use or create credentials that have access to the secrets. Next, make sure you tightly control what can impersonate a service account: are your machines' roles accessible by an attacker exploiting your server? Can service roles from the data-pipeline tooling access the secrets easily? Ensure you include IAM for every cloud component in your threat model (e.g., ask yourself: how can you do elevation of privileges with this component?). See this blog entry for multiple do's and don'ts with examples.\n\nLeverage the temporality of the IAM principals effectively: e.g., ensure that only specific roles and service accounts that require it can access the secrets. Monitor these accounts so that you can tell who or what used them to access the secrets.\n\nNext, make sure that you scope access to your secrets: one should not be simply allowed to access all secrets. In GCP and AWS, you can create fine-grained access policies to ensure that a principal cannot access all secrets at once. For Azure Key Vault, use the recommended Azure RBAC permission model with least-privilege roles. Azure RBAC supports role assignments at the scope of individual keys, secrets, and certificates for limited sharing scenarios, but Microsoft recommends separate vaults per application and environment as the primary security boundary.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
