RBAC, Secrets & Least-Privilege

For banking & government systems, made role-based access, least-privilege service accounts and careful secrets handling first-class design concerns.

Context: compliance-grade systems where a breach is unacceptable. Decision: granular RBAC, least-privilege for every service account, secrets stored securely (mode 0600 / vaulted, never in code), and full audit trails. Trade-off: more setup and stricter workflows for defensible, compliant security.
